Free Website SEO Audit Tool

What does this website SEO audit check?

This free website SEO audit tool reads the page you enter the same way a search engine crawler does, then runs more than 20 checks across five groups: content, technical SEO, social sharing, security and speed. Each check is weighted by how much it usually affects rankings, and the results are combined into one simple score.

Here is what we look at:

• Content: title tag length, meta description, the H1 heading, H2 subheadings, word count and image alt text.
• Technical: canonical tag, robots meta tag (a hidden noindex can remove a page from Google), mobile viewport, language attribute, structured data, favicon, robots.txt and sitemap.xml.
• Security: HTTPS, a redirect from HTTP to HTTPS and the HSTS header.
• Speed: HTML size, server response time, gzip or Brotli compression and redirect chains.
• Social: Open Graph tags that control how your link looks on Facebook, LinkedIn and WhatsApp.

How to run a free SEO audit

1. Type or paste the full address of the page, for example your homepage or a service page.
2. Click Run free audit. Our server downloads the page, then the checks run in your browser.
3. Read your score, then work through the items marked Fail first, followed by Improve.
4. Fix the issues on your site and run the audit again to confirm the score went up.

If your page is not public yet, switch to the Paste HTML code tab and paste the source code instead.

How to read your SEO score

A score of 80 or more means the basics are in good shape. Between 55 and 79 there are several quick wins waiting. Below 55 usually means important elements such as the title, description or H1 are missing, or the page is blocked from indexing. Remember that a perfect technical score does not guarantee rankings. Google also weighs how helpful your content is, your backlinks and your reputation, as explained in the Google SEO Starter Guide.

Why a regular SEO audit matters

Websites change all the time. A developer updates a theme, a plugin adds a second title tag, someone sets a staging page to noindex and forgets to switch it back, or an SSL certificate quietly expires. None of these mistakes are visible to a normal visitor, but each one can cost you rankings and traffic. A quick website SEO audit catches them before Google does.

Running an audit is also the fastest way to understand a website you have never seen before. If you are a freelancer or an agency taking on a new client, an audit gives you a clear starting list in under a minute. If you own a small business website, it shows you which problems are worth paying someone to fix and which ones you can safely ignore.

A good habit is to audit your most important pages once a month and again after every redesign, migration or big content update.

The four pillars of on-page SEO

Most SEO problems fall into one of four groups, and this audit covers all of them:

1. Content signals. Search engines read your title tag, meta description and headings first. A missing H1, a title that is cut off in results or a page with only a few dozen words gives Google very little to work with.
2. Crawling and indexing. If robots.txt blocks a folder, a canonical tag points to the wrong URL or a robots meta tag says noindex, the page may never appear in search, no matter how good it is.
3. Security and trust. HTTPS is a confirmed ranking signal and browsers mark plain HTTP pages as "Not secure". A redirect from HTTP to HTTPS and the HSTS header make sure every visitor lands on the secure version.
4. Speed and experience. Large HTML files, slow server responses, missing compression and long redirect chains all make a page feel slow. Google's Core Web Vitals measure this experience directly.

Common problems the audit finds

From the checks it runs, these are the issues that come up most often on real websites:

• Title tags that are too long, so Google cuts them off with "..." and your main message disappears.
• Missing or duplicate meta descriptions, which leaves Google to pick random text from the page.
• No H1 or several H1 headings, which makes the main topic of the page less clear.
• Images without alt text, which hurts accessibility and image search.
• No canonical tag, so the same page can be indexed under several URLs.
• No sitemap.xml or robots.txt, which makes it harder for search engines to discover your pages.
• No compression, so the page is several times bigger than it needs to be.

Each of these has a dedicated free tool on this site if you want to dig deeper, such as the Meta Tag Checker, Heading Checker and Image Alt Checker.

How to prioritise your fixes

Do not try to fix everything at once. Work in this order:

1. Anything that blocks indexing (noindex, blocked by robots.txt, wrong canonical). These can make a page invisible.
2. Security issues (no HTTPS or no redirect to HTTPS).
3. Title tag and meta description, because they decide whether people click your result.
4. Headings, content length and alt text.
5. Speed improvements such as compression and fewer redirects.

After each round of fixes, run the audit again to confirm the score went up. For a full picture of speed, combine this audit with Google PageSpeed Insights, and for indexing data straight from Google, connect your site to Google Search Console.
