SEO Audit: What It Is, What It Checks, and How to Do One
Updated: 5 days ago
By Spencer Capron, founder of Capron Media. Updated October 30, 2026.
An SEO audit is a check of how well search engines can find, read and rank your website, ending in a list of what to fix first. This guide covers what an audit checks, how to do one yourself, what a paid audit adds, and how often to run one.
What is an SEO audit?
An SEO audit is a review of how well search engines can find, understand and rank a website. It checks the site's technical setup, each page's content and headings, the links other sites point at it, and whether AI answers mention it. It ends with a list of fixes, in the order to make them.
At Capron Media, we describe an SEO audit as an inspection, not a repair. The audit tells you what needs work and how urgent it is. Making the changes is a separate step.
A list of warnings from a tool is not an audit on its own. A crawler can flag hundreds of issues in a few minutes, and many of them will not change your rankings. The audit is the judgement that sorts them: which few matter on your site, and why.
SEO audit vs website audit: what is the difference?
A website audit can cover design, security, accessibility, conversions and SEO. An SEO audit, sometimes called an SEO website audit or SEO site audit, looks only at what affects how a site shows up in search: whether pages can be crawled and indexed, how they are built and written, and what other sites say about them.
If your question is "why do people find my site but not buy?", that is a wider website audit. If it is "why can't people find my site?", start with an SEO audit.
Why is an SEO audit important?
An SEO audit is important because search problems can be invisible from the outside. A page can look fine and still be blocked from Google, compete with another of your own pages, or answer a question nobody asks. An audit finds those problems, ranks them by impact, and tells you which to fix first, so effort goes where it counts.
Three reasons owners run one:
Something changed. Traffic dropped, a redesign is coming, or the site moved platforms.
Nothing is happening. The site has been live for months and does not show up for the searches that matter.
You are about to spend. Before you pay anyone to do SEO work, an audit tells you what the work should be.
What are the three types of SEO audit?
The three main types are technical, on-page and off-page. A technical audit checks whether search engines can reach and read your pages. An on-page audit checks each page's words, headings and links. An off-page audit checks the links and mentions your site gets from other websites. Some audits now add content, local search and AI search.
Type | What it checks | A typical finding | Go deeper |
Technical | Crawling, indexing, robots.txt, XML sitemaps, canonical tags, redirects, speed, mobile, HTTPS | A service page set to noindex, so Google never shows it | Technical SEO audit |
On-page | Titles, meta descriptions, headings, internal links, images | A page with no H1 heading | |
Content | Whether each page answers a real search, and whether two pages compete | Two posts written for the same search, competing with each other | Content audit |
Off-page | Links and mentions from other sites | Competitors have links from local and trade sites that you do not | See "Links" below |
Local (if you serve an area) | Google Business Profile, reviews, NAP (name, address, phone) listings | The hours on the profile differ from the website | Local SEO audit |
AI search | Whether AI answers name you, and whether AI crawlers can read your site | An AI answer to your main question cites three competitors and not you | AI search engine optimization |
What does an SEO audit check?
A full SEO audit checks six areas: technical health, each page's on-page setup, content quality, links from other sites, local listings if you serve an area, and visibility in AI answers. It also compares your site with the sites ranking above you, because that gap can show why they outrank you.
Area | What it checks | How to check it free |
Technical | Can search engines crawl and index every page you want found? | Google Search Console's Pages report; a crawler such as Screaming Frog |
On-page | Does each page have a clear title, one H1 and headings in the searcher's words? | View the page source, or a crawler's titles and headings report |
Content | Does each page answer one real search, without a second page of yours competing? | Search Console's queries for each page; search the question and read the top three results |
Links | Which sites link to you, and to your competitors but not you? | Search Console's Links report shows yours; competitors need a paid tool |
Local | Is your Google Business Profile complete, and do name, address and phone match everywhere? | Your Business Profile dashboard; search your business name |
AI answers | Do AI Overviews and chat tools name you for your customers' questions? | Ask them the questions yourself and note who is cited |
Technical SEO
Crawling and indexing: can search engines reach every page you want found? Our guide to tools that test website crawlability shows how to check, and how search engines crawl websites explains what the crawler does.
Sitemaps and registration: is the XML sitemap submitted to Google and Bing? See how to register your website with search engines.
Duplicate pages and canonical tags: does the same content live at more than one address, and does a canonical tag say which one counts? See whether repeated content hurts SEO.
Broken links and redirects: do links lead to a working page in one step?
Speed and mobile: does the page load quickly and work on a phone? Google's Core Web Vitals measure this.
Hosting and HTTPS: is the site served securely, and does the server respond reliably? See what hosting actually changes for SEO.
The full list is in our technical SEO audit guide.
On-page SEO
Titles, meta descriptions and headings: does each page say plainly what it is about, in the words people search with? See what an on-page SEO check covers.
One H1 per page: a page with no H1, or several, makes its main topic harder to read.
Internal links: do your pages link to each other in a way that shows what is related?
Images: does each image have alt text that describes it?
The basics every page needs: see how to make a site SEO compliant.
Content
Search intent: does the page answer what the searcher wants, in the form they expect? See the golden rule of SEO.
One page per search: is each important search answered by one page, not two of yours competing?
Coverage: are there questions your customers ask that no page on your site answers? See what to do after keyword research and what content-led SEO is.
Freshness: are dates, prices and facts still true?
A content audit goes through every page this way and decides what to keep, update, merge or remove.
Off-page, local and AI search
Links: a backlink audit asks which sites link to you, whether they are relevant, and how they compare with competitors' links.
Local: for a business that serves an area, the Google Business Profile, reviews and NAP listings. See the local SEO audit guide.
AI answers: whether Google's AI Overviews and tools like ChatGPT mention you for the questions your customers ask.
What should an SEO audit report give you?
A good SEO audit report gives you a short list of fixes in priority order. Each finding should name the page it affects, show the evidence, say what to change, and say why it matters. It should also say what it could not check, so a gap in the data is not mistaken for a clean result.
A finding should name | Why |
The page or pages affected | A finding with no page named cannot be acted on |
The evidence | You can check it yourself, or show it to whoever makes the fix |
The fix | So you know whether it is a five-minute edit or a project |
The priority | So the few changes that matter come first |
What was not checked | So a missing account or blocked page is not read as "no problems" |
An SEO audit example
When we audited our own site in October 2026, we checked all 94 live blog posts on capronmedia.com against Search Console and keyword data, and 48 had no recorded target search. 22 were competing with another of our own pages for the same search, in 8 groups; one pair was this guide and our own SEO audit page. Three site pages, Pricing, About and Blog, had no H1 heading. The audit tells you what to fix and in what order; the fixing is separate. On October 30, 2026, we rewrote and republished 92 of those posts, starting with this guide, and merged the other 2 into related posts; that was our own work. The full SEO audit example shows every finding and how to read them, or you can order the full SEO Audit.
How do you do an SEO audit?
Do an SEO audit in order: confirm search engines can reach the site, crawl it for errors, check speed and mobile, review each important page, compare your content with what ranks, check your links, check AI answers, then sort the findings by impact. The short checklist below follows that order.
A short SEO audit checklist
Check what Google already knows. In Google Search Console, open the Pages report to see which pages are indexed and why others are not.
Check your sitemap and robots.txt. Make sure the XML sitemap is submitted in Google and in Bing Webmaster Tools, and that robots.txt does not block pages you want found.
Crawl the site. A crawler visits every page the way a search engine does and lists broken links, redirect chains, noindex tags and duplicate pages.
Check speed and mobile. Run your main pages through PageSpeed Insights and look at the Core Web Vitals report in Search Console.
Review each important page. Title, meta description, one clear H1, headings that match what people search, alt text, and links to related pages.
Look for pages competing with each other. If two of your pages show up for the same search, decide which one should own it.
Compare your content with what ranks. Search your main question and read the top three results. Note what they answer that you do not.
Check your links. See which sites link to you, and which link to competitors but not to you.
Check AI answers. Ask Google and ChatGPT the questions your customers ask. Note who gets named and cited.
Put the findings in order. Sort by impact and effort, and write down who will make each fix.
For every check, with how to do each one free, see the full SEO audit checklist.
If your traffic has suddenly dropped, start with the dates. Our guides to recovering a website that is losing traffic and what to do when a Google core update hits cover that case.
Can you do an SEO audit yourself?
Yes. A beginner can run a basic SEO audit with free tools: Google Search Console, PageSpeed Insights and a site crawler will catch the obvious problems. The hard part is judgement: knowing which of the issues a tool flags will actually change your rankings, and which can wait.
A paid audit adds that judgement, plus the parts free tools do not cover well: a comparison with competitors, a review of links, and a check of AI answers.
Which tools are used for an SEO audit?
These five cover most of an audit. The first three are free. The last row is our own free option.
Tool | What it is for | Cost |
Google Search Console | Which pages are indexed, which searches you appear for, errors Google found | Free |
Bing Webmaster Tools | The same for Bing | Free |
PageSpeed Insights | Page speed and Core Web Vitals | Free |
A site crawler, such as Screaming Frog or Sitebulb | Broken links, redirects, missing titles, duplicate pages | Screaming Frog's free version crawls up to 500 URLs per crawl (as of October 30, 2026); Sitebulb is paid, with a free trial |
An SEO suite, such as Semrush or Ahrefs | Keywords, competitors and backlinks | Paid |
Capron Media (ours) | Free Lite subscription, site health: see what on your site needs fixing, counted by urgency, with the top three in plain words. Lite does not include the work on your site. Starter does. | Free |
We compare more of them, with what each is good at, in SEO audit tools compared.
Can ChatGPT do an SEO audit?
ChatGPT can help with parts of an SEO audit, not the whole thing. It can read a page you paste in, explain a warning from a tool, and suggest clearer titles. It cannot see your Search Console data unless you export it, it is not a site crawler, and it can state things that are wrong. Check what it tells you.
Free SEO audit vs paid SEO audit
A free SEO audit is usually a short read of your biggest issues. A paid audit goes through every page and finding, compares you with competitors, and gives you a full plan. Start free to see whether there is anything worth fixing; pay when you want the whole list.
A free website health check or SEO health check tool gives you a score and a list of warnings in a minute or two. It is a fair place to start, as long as you remember a score is not a plan.
At Capron Media, the free check comes with a free Lite subscription, and the full SEO Audit is ordered in your portal. Here is what each covers:
Free check | Full SEO Audit | |
What to fix first across the site | Top three | Every finding |
Your home page | Top three | Page by page |
Local results | Top three | In full |
Competitors and gaps | Not included | Included |
AI answers | Not included | Included |
Teardown and PDF | Not included | Included |
Your own Search Console and Analytics data | Not included | For your own site |
A free check reads public data, so there is nothing to connect.

How much is an SEO audit?
SEO audit prices vary with the size of the site, how deep the audit goes, and how much a person reads rather than a tool. At Capron Media, the full SEO Audit is $250, paid once; see what the full SEO Audit covers before you order.
How long does an SEO audit take?
A tool crawl of a small site takes minutes. A full audit, with a person reading the results and writing the plan, usually takes days, and longer for a large site. At Capron Media, a full SEO Audit is delivered in 3 to 5 business days from when your payment is confirmed and your business details are complete.
How often should you get an SEO audit?
For a small business website, we suggest a full SEO audit about once a year, plus one before a redesign or platform move, and one after a sudden drop in traffic. Advice varies: some agencies say every quarter. Between audits, keep watching what changed so a new problem does not wait a year.
Get an audit sooner if:
your traffic or rankings dropped and you do not know why;
you are about to redesign the site or move platforms (see website redesign mistakes that destroy rankings);
the site gets visitors but no enquiries;
you have never had one.
Between audits: SEO monitoring. Monitoring is the light, regular check that runs between full audits: where you rank, what moved, and whether a new problem appeared. Our guide to SEO monitoring covers the tools. After an audit, a free Lite subscription keeps showing what on your site needs fixing and what changed since the last check.
Does an SEO audit cover AI search?
A current SEO audit should. AI answers such as Google's AI Overviews and ChatGPT now answer many questions before anyone clicks. An AI SEO audit checks whether AI crawlers can read your site, whether your pages answer questions plainly enough to be quoted, and whether AI answers name you for the questions your customers ask.
SEO is not being replaced; it is widening. Google's AI Overviews mostly cite sites that already rank. In a July 2025 study of 5,000 keywords, Semrush found AI Overviews cited a site from Google's top 10 for the same search about 86% of the time, and a page from that top 10 about 67% of the time. So much of the work that gets a page into Google's top 10 is the same work that gets it cited there.
The full SEO Audit from Capron Media includes AI answers. For the wider picture, see our guide to AI search engine optimization.
Will an SEO audit improve my rankings?
Not on its own. An audit tells you what to fix; rankings change when the fixes are made, starting with the ones that matter most. You can make them yourself, hand the report to whoever runs your site, or have someone make them for you.
At Capron Media, the audit report ends with what to do next. If you want the changes made for you, the Starter subscription makes them on the site you already own. If the audit points to a larger piece of work, it can be quoted as a separate SEO project. If you would rather make the changes yourself, start with how to improve SEO on your website.
How do you choose who does your SEO audit?
Ask to see a sample report before you pay. A good provider shows findings tied to named pages, puts them in order, gives the price in writing, says what data it could not see, and has a person check the report. Be wary of anyone promising rankings by a date.
Ask | A good answer |
Can I see a sample report? | Yes, with findings tied to pages and put in order |
What will it cost, and what does that cover? | A price in writing, before the audit starts |
Who reads the results? | A person reviews the report before you get it |
What can you not see? | They say which data was missing or limited |
What happens after? | The report ends with next steps, and says who can make the fixes |
If you want one done for you, see our SEO audit services: start with the free check, then order the full audit when you want everything.
