“SEO audit,” “SEO checker,” “website audit,” “SEO report” — people search for all of these expecting roughly the same thing: some tool to look at their website and tell them what’s wrong. Fair question, and the honest answer is that a proper audit is checking a fairly specific, unglamorous list of things. Here’s what’s actually behind the report.
It’s not one thing — it’s a checklist
A good SEO audit crawls your website the way a search engine does, then checks it against the things that affect whether Google can find your pages, understand them, and want to show them to someone searching. None of it is secret. Here’s what’s actually on the list.
1. Page titles, meta descriptions, and canonical tags
Every page has a title and a short description that shows up in Google’s search results — if yours are missing, generic (“Home”), or duplicated across multiple pages, Google has less to work with. Canonical tags tell Google which version of a page is the “real” one when the same content is reachable more than one way (with or without www, with or without a trailing slash) — get this wrong and you can accidentally split your own page’s ranking in two.
2. Duplicate pages, thin content, and missing search intent
If two pages on your site say almost the same thing, Google has to guess which one to show — and often shows neither with much confidence. “Thin content” means a page with barely anything on it (a service page that’s one sentence long, say). “Search intent” is just whether the page actually answers the question someone typed in — a page titled “Our Services” that never mentions what those services are doesn’t match much of anything.
3. Sitemap gaps and pages that are hard for crawlers to find
A sitemap is a list of your pages that you hand to Google directly, so it doesn’t have to stumble onto everything by clicking around. If a page isn’t in the sitemap and isn’t linked from anywhere else on your site, Google may never find it at all — which means it can’t rank for anything, no matter how good the content is.
4. Broken internal links and dead external links
A link on your own site pointing to a page that no longer exists is a small trust signal against you, and a frustrating dead end for a visitor who was one click from calling you. Links out to other sites that now 404 have the same effect in miniature. Neither is disqualifying on its own, but a site with a dozen of them looks unmaintained — to Google and to a real person.
5. Missing image alt text and basic accessibility signals
Alt text is the written description behind an image — it’s what a screen reader announces to someone who can’t see the image, and it’s also one more piece of information Google uses to understand a page. A site full of unlabelled images isn’t just a missed SEO opportunity; it’s a worse experience for anyone using assistive technology to browse it.
What a free checker tool can and can’t tell you
Most free tools — including ours — are genuinely useful for the list above: the technical, crawlable, “yes or no” issues. What they generally can’t tell you is whether your actual writing answers the question someone’s searching for, or whether your business is a good match for the people typing that search in. That part still takes a human read, not a crawler.
What to actually do with the results
An audit report is a list of problems, not a priority order — that part’s on you (or whoever you hand it to). Some rough guidance:
- Fix broken links and missing titles first. These are quick, low-risk, and directly affect how Google reads every page.
- Treat duplicate or thin content as a bigger job. It usually means rewriting or merging pages, not just editing a tag — budget proper time for it.
- Don’t panic about every warning. A 40-item report doesn’t mean 40 things are broken; some flags are minor and some barely matter for a small local site. If you’re not sure which is which, that’s a reasonable thing to ask a developer to triage for you.
The honest answer
An SEO audit isn’t checking anything mysterious — it’s confirming that Google can actually crawl, read, and trust your site, which is the unglamorous groundwork underneath everything else people call “SEO.” If you want to see exactly where your own site stands, our free SEO check runs this same list against your URL and emails you a plain-English report — no login required.
