You can check the SEO of a website for free in about ten minutes. You do not need a paid suite for the first pass: a few free tools and a clear order of checks are enough to find the problems that hold most small sites back.
Start with the question: can Google find and index your pages?
Everything else depends on this. If a page is blocked or not indexed, better titles will not help. Check three things first:
- Indexing. Search for
site:yourdomain.comin Google. If almost nothing appears, the site has an indexing problem, not a content problem. Google Search Console, which is free, shows the exact reason per URL in the Pages report. - robots.txt. Open
yourdomain.com/robots.txt. A singleDisallow: /left over from a staging site blocks crawling of the whole domain. - Noindex. View the page source and search for
noindex. It can sit in a meta robots tag or in an HTTP header.
Check the basics on each important page
Pick your home page, your main category or service page and one article. For each one, look at:
- Title tag. One per page, written for that page, with the main topic near the start. Long titles are cut off in results, so keep them under roughly 60 characters.
- Meta description. Not a ranking factor on its own, but it is the text people read before clicking. Describe what the page offers in one or two sentences.
- One H1 that matches the topic, followed by H2 and H3 headings in a logical order.
- Canonical tag. It should point to the clean version of the URL. A missing or wrong canonical is a common cause of duplicate pages competing with each other.
- Image alt text for images that carry meaning.
Check speed and mobile use
Run the page through PageSpeed Insights. Google's published thresholds for a good experience are a Largest Contentful Paint of 2.5 seconds or less, an Interaction to Next Paint of 200 milliseconds or less and a Cumulative Layout Shift of 0.1 or less. Heavy images, render-blocking scripts and a slow first response from the server are the usual causes of poor results. Open the page on a phone as well: text that needs zooming or buttons that are too close together hurt both users and rankings.
Check security and trust signals
Search engines and browsers judge the same technical foundations. Confirm that the site loads over HTTPS without warnings, that HTTP redirects to HTTPS in a single step and that no images or scripts load over plain HTTP. Security headers such as HSTS and a Content-Security-Policy are not direct ranking factors, but a site that triggers browser warnings loses visitors before SEO matters.
Use an automated scan to cover everything at once
Doing all of this by hand for every page is slow. An automated checker runs the same checks in one pass and sorts the results. SEOCheck-AI scans a domain and reports on indexability, on-page SEO, content, performance, trust and security, and readiness for AI search. Each check has a status, a score and a plain-language fix. It does not measure rankings, traffic or backlinks, so use Search Console alongside it for those.
Common mistakes when checking SEO yourself
- Checking only the home page. Templates differ. A product page, a blog post and a category page can each have their own problems, so test one of each type.
- Trusting a single tool. A scan finds technical issues, Search Console shows real queries and indexing, and PageSpeed Insights covers speed. Each answers a different question.
- Fixing symptoms instead of causes. If fifty pages share the same missing title, fix the template once rather than editing fifty pages.
- Ignoring the date of the data. Search Console data lags by a day or two, and a scan shows the site as it is at that moment. Compare like with like.
Turn the results into a fix list
Do not try to fix everything. Work in this order:
- Anything that blocks indexing: robots rules, noindex, broken canonicals, pages returning errors.
- Site-wide problems that repeat on every page, such as missing titles from a template or slow server response.
- Page-level improvements on the pages that already get impressions in Search Console.
- Small polish: alt text, heading structure, minor warnings.
Re-run the check after each batch of fixes so you can see what changed. For a broader list to follow, see the technical SEO audit checklist.
FAQ
Is it really possible to check SEO for free?
Yes. Google Search Console, PageSpeed Insights and a free automated scan cover indexing, speed and technical problems. Paid tools add keyword research, rank tracking and backlink data.
How often should I check my website SEO?
Check after every significant change such as a redesign, a migration or a new template, and run a routine check about once a month.
What is the single most important thing to check first?
Whether your important pages are indexed. Without indexing, nothing else you fix will show up in search.
Check your own website
Reading a checklist is useful, but a scan shows what is actually wrong on your site. Run a free SEO check, enter your domain and get a score for each area with a ranked list of fixes. The baseline report needs no account. You can also read what the SEO checker analyzes or open the free SEO check page for an example report.
