What Should an SEO Audit Include? 25-Point Checklist

What Should a Good SEO Audit Include?

If an SEO company tells you the first step is an audit, that's usually reasonable.

The harder question is:

What should a good SEO audit actually include?

Some SEO audits are genuinely useful.

They identify why your website isn't ranking, show where competitors are beating you, uncover technical problems, find missed keyword opportunities, and tell you exactly what should be fixed first.

Others are essentially:

A 75-page PDF exported from an SEO tool.

Lots of charts.

Lots of warnings.

Very little explanation about what actually matters.

A good SEO audit should examine technical SEO, crawling and indexing, website structure, on-page optimization, content, keywords, backlinks, local SEO, competitors, user experience, conversions, and measurement—and then prioritize the findings based on business impact.

The last part is especially important.

An audit isn't valuable because it finds 247 problems.

It's valuable because it tells you:

Which problems are actually preventing you from getting found—and what should you do about them?

This guide explains everything a good SEO audit should include, which findings matter most, and how to tell whether you're receiving useful SEO analysis or just an automated report.

What Is an SEO Audit?

An SEO audit is a systematic review of your website and broader search presence designed to identify problems and opportunities affecting your visibility in search engines.

Think of it like an inspection.

Before deciding what SEO work to perform, you first need to understand the current condition of the property.

An audit can uncover issues such as:

  • Important pages not appearing in Google

  • Broken internal links

  • Weak service pages

  • Poor keyword targeting

  • Duplicate content

  • Technical problems

  • Missing local signals

  • Weak backlinks

  • Poor website structure

  • Slow or frustrating pages

  • Google Business Profile problems

  • Competitors with stronger content

  • Valuable keywords you're not targeting

  • Traffic that isn't converting

Google itself recommends that businesses considering an SEO provider ask for a technical and search audit that explains what should be improved and why. citeturn926460search5

The best SEO audits don't stop at identifying issues.

They turn those findings into an action plan.

The 12 Core Areas a Good SEO Audit Should Include

A comprehensive SEO audit should generally examine these areas:

  1. Crawling and indexing

  2. Technical SEO

  3. Site architecture

  4. On-page SEO

  5. Keyword targeting

  6. Content quality and gaps

  7. Internal linking

  8. Backlinks and authority

  9. Local SEO

  10. Competitor analysis

  11. User experience and conversions

  12. Analytics and measurement

Let's break each one down.

1. Crawling and Indexing

Before worrying about rankings, you need to answer a more fundamental question:

Can Google actually find and index your important pages?

Google explains that crawling and indexing are foundational to appearing in Search. Pages need to be accessible to Googlebot and contain indexable content before they can become eligible to appear in results. citeturn926460search11turn926460search16

A good SEO audit should investigate:

  • Which pages Google knows about

  • Which pages are indexed

  • Which important pages aren't indexed

  • Which pages shouldn't be indexed

  • Robots.txt rules

  • Noindex tags

  • Canonical tags

  • XML sitemap setup

  • Redirects

  • HTTP status codes

  • Crawl errors

  • Duplicate URLs

Example

Imagine your business has a page for:

Emergency Plumbing Services

It's one of your most profitable services.

But the page accidentally contains a noindex directive.

You could spend months improving the content and building backlinks to that page without solving the fundamental problem.

Google isn't indexing it.

That is why a proper SEO audit starts with technical accessibility.

2. Technical SEO

Technical SEO looks at whether your website is built in a way that allows search engines to efficiently access, understand, and serve its pages.

A technical SEO audit may examine:

  • Broken links

  • Redirect chains

  • 404 pages

  • Duplicate URLs

  • Canonicalization

  • Sitemap errors

  • Structured data

  • HTTPS

  • JavaScript rendering

  • Mobile compatibility

  • Page speed

  • Core Web Vitals

  • Server errors

Google's technical requirements emphasize that Googlebot must be able to access a working page and that the page must contain indexable content. citeturn926460search11

Don't Treat Every Technical Warning as an Emergency

This is important.

SEO tools love finding errors.

That doesn't mean every warning deserves immediate attention.

An automated audit might report:

172 images missing alt attributes.

Potentially worth fixing.

But if your highest-value service pages are accidentally blocked from indexing, that's clearly more urgent.

A good SEO expert separates:

Critical problems

from:

Things that would be nice to clean up.

3. Website Speed and Core Web Vitals

Website experience should also be reviewed.

Google's Core Web Vitals currently focus on real-world user experience related to loading performance, responsiveness, and visual stability. citeturn926460search4

An audit should look for major problems such as:

  • Extremely slow pages

  • Large unoptimized images

  • Excessive JavaScript

  • Layout shifts

  • Poor mobile performance

  • Scripts delaying interaction

However, page speed shouldn't become an obsession.

A site scoring 92 instead of 96 isn't necessarily your biggest SEO problem.

The audit should put technical performance into context alongside content, authority, and search intent.

4. Mobile SEO

Your audit should verify that important content and functionality work properly on mobile devices.

Google uses the mobile version of websites for indexing and ranking under mobile-first indexing. citeturn926460search17

Review:

  • Mobile navigation

  • Text readability

  • Buttons

  • Forms

  • Phone links

  • Page layout

  • Popups

  • Missing mobile content

  • Loading performance

For a local service business, this is especially important.

Someone whose furnace stops working may search from their phone and call immediately.

If your website is technically optimized but the phone number is almost impossible to tap, you're losing opportunities.

5. Site Architecture

Site architecture describes how your pages are organized and connected.

A strong website structure helps both visitors and search engines understand:

  • What your business does

  • Which pages are most important

  • How services relate

  • How supporting content connects to commercial pages

Imagine an HVAC website structured like this:

Homepage

→ AC Services
→ Furnace Services
→ Heat Pumps
→ Indoor Air Quality

Under AC Services:

→ AC Repair
→ AC Installation
→ Emergency AC Repair

That is much easier to understand than placing 75 unrelated pages into one giant website structure.

A good audit should evaluate:

  • Navigation

  • URL structure

  • Page hierarchy

  • Orphan pages

  • Content depth

  • Service organization

  • Location pages

  • Internal linking

6. On-Page SEO

Next, the audit should examine whether important pages clearly communicate what they're about.

On-page SEO commonly includes:

  • Page titles

  • Meta descriptions

  • H1 headings

  • Subheadings

  • Page content

  • URLs

  • Images

  • Internal links

  • Calls to action

  • Structured data where appropriate

The goal isn't to repeat a keyword 47 times.

It's to make the page clearly useful for the searcher's intent.

Example

Suppose a plumber has one page called:

Services

That page briefly mentions:

  • Water heaters

  • Sewer repair

  • Drain cleaning

  • Leak detection

  • Repiping

Meanwhile, competitors have detailed pages for each service.

The audit might recommend creating dedicated pages because one thin “services” page may not adequately address all those distinct search intents.

7. Keyword Targeting

An SEO audit should tell you whether your website targets the searches most likely to produce business.

Not just high-volume keywords.

Valuable keywords.

For example, an HVAC company might encounter:

Informational

“How long does an AC unit last?”

Commercial

“best HVAC company in Denver”

Transactional

“AC repair near me”

Different keywords represent different stages of the buying journey.

A useful keyword audit should evaluate:

  • Existing keyword rankings

  • High-intent keywords

  • Missing service keywords

  • Local keywords

  • Informational opportunities

  • Search intent

  • Competitor keywords

  • Pages ranking for the wrong query

  • Keyword cannibalization

Keyword Cannibalization

This can happen when several pages compete for very similar searches.

For example:

  • /ac-repair

  • /air-conditioner-repair

  • /air-conditioning-service

  • /ac-service

If all four pages serve essentially the same purpose, your website may have created unnecessary overlap.

The audit should identify whether pages should be:

  • Combined

  • Redirected

  • Repositioned

  • Differentiated

8. Content Quality

Content is one of the most important parts of a modern SEO audit.

Google's current guidance emphasizes creating helpful, reliable, people-first content rather than content primarily designed to manipulate search rankings. citeturn926460search12

Your audit should evaluate:

  • Thin pages

  • Outdated content

  • Duplicate content

  • Generic content

  • Missing information

  • Weak service pages

  • Existing articles

  • Search intent

  • Content freshness

  • Expertise

  • Original information

Ask:

Does this page actually deserve to rank?

That's a better question than:

Does this page have 1,500 words?

What Good Content Analysis Looks Like

Imagine you're a roofer targeting:

“How much does a new roof cost?”

An audit might compare your page against the current search results and find that competitors provide:

  • Pricing ranges

  • Cost by roof size

  • Cost by material

  • Labor considerations

  • Tear-off costs

  • Location factors

  • FAQs

Your article provides only:

“Roof prices vary. Contact us for an estimate.”

Technically, you have a page targeting the keyword.

Practically, you're not answering the question well.

That is a content problem.

9. Content Gap Analysis

A content audit shouldn't only analyze what already exists.

It should identify what is missing.

For example, your competitors may attract customers from searches such as:

  • How much does AC repair cost?

  • How long does a furnace last?

  • Should I repair or replace my AC?

  • Heat pump vs furnace

  • Why is my AC blowing warm air?

If you don't have useful pages answering those questions, you may be missing opportunities to reach customers earlier in their buying process.

A content gap analysis can identify:

  • Missing service pages

  • Missing location pages

  • Missing informational topics

  • Comparison topics

  • Cost-related searches

  • FAQs

  • Competitor content opportunities

This is where the audit begins turning into an actual content strategy.

If you're interested in how content fits into a broader organic strategy, the Helios Lab SEO blog covers SEO content, local search, backlinks, pricing, and hiring SEO providers.

10. Internal Linking

Internal links connect pages within your own website.

They're easy to overlook.

A good audit should identify:

  • Important pages with very few internal links

  • Orphan pages

  • Contextual linking opportunities

  • Poor navigation

  • Broken internal links

  • Overuse of generic anchor text

Imagine you publish an article:

“How Much Does Furnace Replacement Cost?”

That article should probably link naturally to your:

Furnace Replacement Service

page.

And your furnace service page might link to relevant educational resources.

This creates a logical path:

Informational content → commercial service → conversion

Internal linking isn't just an SEO checkbox.

It helps visitors move through your website.

11. Backlink Profile

Backlinks are links from other websites to yours.

A backlink audit should analyze:

  • Which websites link to you

  • Which pages attract links

  • Whether links are relevant

  • Whether suspicious links exist

  • Competitor backlink gaps

  • Local backlink opportunities

  • Lost backlinks

  • Linkable content

The important distinction is quality versus quantity.

A competitor having 2,000 backlinks does not necessarily mean you need 2,001.

You need to understand:

Where is their authority coming from?

For example:

  • Local organizations

  • News publications

  • Industry sites

  • Associations

  • Suppliers

  • Relevant editorial content

Those patterns can reveal realistic opportunities.

12. Competitor Analysis

No SEO audit is complete without looking at who already occupies the search results you want.

Your business doesn't rank in a vacuum.

If four competitors consistently outrank you, your audit should investigate why.

Compare:

  • Website authority

  • Service pages

  • Content

  • Backlinks

  • Reviews

  • Google Business Profiles

  • Site structure

  • Local citations

  • Keyword coverage

The useful question is:

“What do the businesses beating us consistently do better?”

Then:

“Which of those differences can we realistically close?”

Competitor analysis turns SEO from guesswork into a comparison.

13. Local SEO Audit

For a local business, this should be a major section—not an afterthought.

A local SEO audit should evaluate:

  • Google Business Profile

  • Business categories

  • Services

  • Business information

  • Reviews

  • Review velocity

  • Local rankings

  • Map pack visibility

  • Citations

  • Name/address/phone consistency

  • Location pages

  • Local competitors

  • Local backlinks

At Helios Lab, our current Local SEO service begins with auditing the website, Google Business Profile, local listings, speed, mobile setup, and citations before moving into fixes and ongoing tracking. The site currently describes the process as identifying why the business isn't ranking and then fixing the issues rather than simply handing over a report. citeturn448532view0

Google Business Profile Audit

Review:

  • Primary category

  • Secondary categories

  • Business name

  • Phone number

  • Website URL

  • Services

  • Hours

  • Photos

  • Reviews

  • Description

  • Duplicate profiles

For a local business, the website is only part of your search presence.

14. Citation Audit

Citations are online listings or references containing business information such as:

Name + address + phone number

An audit may uncover:

  • Old phone numbers

  • Incorrect addresses

  • Duplicate listings

  • Missing profiles

  • Inconsistent business names

These problems are especially common when:

  • Businesses move

  • Companies rebrand

  • Phone numbers change

  • Multiple locations open

Your audit should identify the important inconsistencies rather than simply promise to submit your business to hundreds of meaningless directories.

15. Review and Reputation Analysis

Reviews influence both conversion and local visibility.

A local SEO audit should compare:

  • Review count

  • Average rating

  • Review recency

  • Review cadence

  • Competitor reviews

  • Review responses

But avoid turning review optimization into something manipulative.

The objective should be establishing a consistent, legitimate process for asking real customers for feedback.

16. Conversion Analysis

This is an area many SEO audits miss completely.

SEO's job isn't only getting traffic.

It's helping acquire customers.

Your audit should therefore look at whether visitors can easily take the next step.

Review:

  • Phone number visibility

  • Mobile click-to-call

  • Contact forms

  • Quote forms

  • Booking flows

  • Calls to action

  • Reviews/testimonials

  • Trust signals

  • Service area clarity

Imagine your website moves from 1,000 to 2,000 monthly visitors but still generates five leads.

You may not need more traffic.

You may need a better website experience.

17. Analytics and Tracking

A serious SEO audit should verify whether results can actually be measured.

Google Search Console can show how Google crawls, indexes, and serves your website and how your pages perform in Search. Google also recommends combining Search Console and Analytics data for a more complete view of how users discover and interact with a site. citeturn926460search30turn926460search19

Check:

  • Google Search Console

  • Google Analytics

  • Conversion events

  • Phone tracking

  • Form tracking

  • Organic traffic

  • Landing pages

  • Search queries

For a local business, you eventually want to move beyond:

“Organic sessions increased 34%.”

Toward:

“Organic search generated 23 calls and 11 quote requests.”

18. AI Search Visibility

In 2026, I'd also expect a modern SEO audit to consider how your business appears across emerging AI-powered search experiences.

But don't let someone sell you a fake separate “AI audit” full of unsupported hacks.

Google's current guidance says the same foundational SEO practices remain relevant to its AI Overviews and AI Mode. It recommends clear technical structure, unique content, accurate information, and measuring visibility through Search Console rather than chasing special AI-only tricks. citeturn926460search15

So an AI-search review can reasonably ask:

  • Is your content clear enough to extract answers from?

  • Are important claims specific?

  • Do you publish original information?

  • Is your business information consistent?

  • Does your site demonstrate expertise?

  • Are you earning legitimate mentions and links?

  • Are your important pages indexable?

The answer shouldn't be:

“Install a secret AI file and you'll rank in ChatGPT.”

What Should the Final SEO Audit Deliverable Look Like?

This may be the most important part.

A great audit shouldn't end with:

“Here are 143 issues. Good luck.”

It should organize findings by priority.

I prefer four levels.

Priority

Meaning

Example

Critical

Blocking search visibility or causing major loss

Important pages not indexed

High

Strong potential effect on rankings/leads

Missing core service pages

Medium

Worth improving after major issues

Weak internal linking

Low

Cleanup or minor optimization

Small metadata improvements

Then each recommendation should answer:

What's Wrong?

Example:

“Your AC installation page is not indexed.”

Why Does It Matter?

“This is one of your highest-value services, so the page currently has almost no opportunity to generate organic search traffic.”

What Should Be Done?

“Identify the indexing cause, correct it, request recrawling, and verify indexing in Search Console.”

Who Should Fix It?

Developer, SEO specialist, writer, business owner, etc.

What Should Be Fixed First?

Priority.

That's a useful audit.

What Should NOT Be in an SEO Audit?

Be skeptical when an audit is dominated by things such as:

  • Proprietary SEO scores

  • Hundreds of low-impact warnings

  • Keyword density percentages

  • Arbitrary word-count targets

  • Huge lists of generic recommendations

  • No competitor context

  • No prioritization

  • No explanation

  • No business impact

SEO tools are useful.

But software output isn't the same as professional analysis.

Google's June 2026 guidance on third-party SEO tools specifically reminds businesses that external SEO tools do not have access to Google's internal ranking data and that their scores and predictions are their own. citeturn926460search18

Your audit should use tools as inputs.

Not treat their scores as Google itself.

Free SEO Audit vs. Paid SEO Audit

Both can be useful.

Free SEO Audit

A free audit usually works best as a preliminary assessment.

You might expect:

  • Major technical problems

  • Current rankings

  • Google Business Profile issues

  • Local listing problems

  • Obvious content gaps

  • High-level competitor analysis

The purpose is usually to identify whether there's enough opportunity to justify working together.

Helios Lab currently offers this type of initial review, describing its SEO audit process as scanning the website, Google profile, and local listings to identify why customers may not be finding the business. citeturn714291view2

Paid SEO Audit

A paid standalone audit can reasonably go much deeper.

It may include:

  • Technical crawling

  • Full indexing analysis

  • Detailed content audit

  • Keyword mapping

  • Backlink analysis

  • Competitor analysis

  • Site architecture

  • Technical implementation recommendations

  • Content strategy

  • Prioritized roadmap

The key isn't whether the audit is free or paid.

It's whether its depth matches what was promised.

How Long Should an SEO Audit Take?

There is no universal number.

A five-page local business website doesn't need the same audit as:

  • A 50,000-page ecommerce site

  • A national marketplace

  • A 100-location service company

Scope should depend on:

  • Website size

  • Number of locations

  • Technical complexity

  • Existing content

  • Competitiveness

  • Business goals

Be cautious of anyone claiming they fully audited a complex website in five minutes.

Software can crawl it quickly.

Analysis requires interpretation.

How Often Should You Perform an SEO Audit?

You don't need a massive audit every month.

For most small businesses, an in-depth audit is especially useful:

  • Before beginning SEO

  • After a major website redesign

  • After a domain migration

  • When traffic drops unexpectedly

  • When rankings plateau

  • When acquiring a business/site

  • When changing SEO providers

Ongoing SEO should then include monitoring so major issues are caught before another full audit is necessary.

The 25-Point SEO Audit Checklist

Here's a simple checklist you can use when evaluating an audit.

A good SEO audit should answer:

Technical


  • Can Google crawl important pages?


  • Are important pages indexed?


  • Are robots/noindex rules correct?


  • Is the sitemap configured properly?


  • Are redirects and errors handled correctly?


  • Does the site work well on mobile?


  • Are there significant speed or Core Web Vitals issues?

Website


  • Is the site architecture logical?


  • Are important service pages present?


  • Are pages targeting the right search intent?


  • Are titles and headings clear?


  • Is internal linking strong?

Content


  • Is existing content actually useful?


  • Are important topics missing?


  • Are pages duplicated or competing against each other?


  • Are there opportunities to add original expertise?

Authority


  • Who links to the website?


  • Are backlinks legitimate and relevant?


  • Where do competitors earn their authority?

Local SEO


  • Is the Google Business Profile optimized?


  • Are citations accurate?


  • How strong are reviews versus competitors?


  • How visible is the business in local/map results?

Business Performance


  • Is organic traffic being measured?


  • Are phone calls and forms tracked?


  • Which SEO problems should be fixed first?

If the audit cannot clearly answer those questions, it probably isn't finished.

Frequently Asked Questions About SEO Audits

What should a good SEO audit include?

A good SEO audit should review technical SEO, crawling and indexing, website architecture, on-page optimization, keyword targeting, content quality, internal linking, backlinks, competitors, local SEO, conversion performance, and analytics.

Most importantly, it should prioritize recommendations based on impact.

What is the most important part of an SEO audit?

The most important part is identifying what is actually preventing the website from performing better.

Finding problems is relatively easy.

Prioritizing the right problems is where expertise matters.

What is a technical SEO audit?

A technical SEO audit examines whether search engines can efficiently crawl, render, understand, and index a website.

It may review indexing, robots directives, sitemaps, redirects, status codes, canonicalization, mobile performance, structured data, and other technical elements.

Does an SEO audit include keywords?

It should.

A good audit should analyze what keywords the website currently ranks for, which commercial keywords matter, what competitors rank for, and which valuable searches aren't currently targeted.

Does an SEO audit include backlinks?

A comprehensive audit should evaluate the website's backlink profile and compare it with competitors.

The goal isn't simply counting links. It should identify authority gaps, suspicious patterns, strong existing links, and realistic opportunities.

Should a local SEO audit include Google Business Profile?

Absolutely.

For a local business, the audit should examine the website and Google Business Profile, citations, reviews, local competitors, location pages, and map visibility.

Can I do an SEO audit myself?

Yes.

Tools such as Google Search Console can help business owners identify many issues. Google's Search Console provides first-party data about crawling, indexing, search queries, and Search performance. citeturn926460search30

The challenge is usually determining which findings matter most and how to fix them.

Are automated SEO audits accurate?

Automated tools can identify many technical conditions and potential problems.

They are less reliable at determining business priorities, search intent, content usefulness, competitor strategy, and whether a particular warning is actually important.

Use automated audits as diagnostic inputs—not as the final strategy.

How much should an SEO audit cost?

Pricing varies substantially depending on website size, depth, complexity, and whether the audit includes strategy and implementation.

Some agencies offer limited initial audits at no cost as part of the sales process, while comprehensive standalone audits can be paid projects.

Compare scope rather than price alone.

Should an SEO agency fix the problems it finds?

That depends on the agreement.

Some audits are standalone consulting projects.

Others lead directly into implementation.

Before buying, clarify whether you're receiving:

Diagnosis only

or:

Diagnosis + implementation.

Will an SEO audit guarantee higher rankings?

No.

An audit identifies problems and opportunities. Fixing those issues can improve a site's ability to compete, but no provider can guarantee Google's exact ranking response.

The Bottom Line: A Good SEO Audit Should Tell You What to Do Next

A good SEO audit is not a collection of warnings.

It's a decision-making document.

When it's finished, you should understand:

Where are we losing visibility?

What are competitors doing better?

Which technical problems matter?

Which pages need improvement?

What content are we missing?

Do we have enough authority?

Is our local SEO competitive?

Can we measure leads?

And most importantly:

What should we fix first?

That's the difference between an audit and a software export.

The tool finds problems.

The SEO expert determines which problems matter.
