WHAT IT IS
A technical SEO audit is a structured review of the technical and on-page elements that affect how search engines crawl, index and understand your website. This free technical SEO audit tool checks nine of them on every page it can reach: the title tag, meta description, H1 heading, image alt attributes, word count, canonical tag, noindex directive, mobile viewport tag and whether the page loads at all.
SEO problems rarely live on one page. A meta description template that was never set up, a theme that outputs two H1 tags, or a plugin setting that adds noindex all repeat across dozens or hundreds of URLs. Checking one page tells you that page is fine. Checking the whole site shows you the pattern, and a pattern is usually one fix.
WHAT IT CHECKS
| Check | What it flags | Why it matters | How to fix it |
|---|---|---|---|
| Title tag | Missing, or outside 30 to 60 characters | The title is the headline in search results and a strong relevance signal. | Write a unique title per page, put the topic first and keep it near 60 characters. |
| Meta description | Missing, or outside 70 to 160 characters | Not a ranking factor, but it shapes the snippet and the click. | Write a unique summary of 120 to 160 characters with a reason to click. |
| H1 heading | Missing, or more than one | One H1 states the page topic clearly to readers and crawlers. | Use exactly one H1 that matches the topic of the page. |
| Image alt attributes | Images with no alt attribute | Alt text supports accessibility and image search. | Add short, descriptive alt text. Use empty alt only for decorative images. |
| Word count | Fewer than 300 words | Very thin pages often fail to answer the search intent. | Add useful detail, or merge, redirect or noindex pages that serve no purpose. |
| Canonical tag | No canonical declared | Canonicals tell Google which URL is the preferred version. | Add a self-referencing canonical to every indexable page. |
| Noindex directive | Pages set to noindex | A stray noindex removes a page from search results. | Remove noindex from pages that should rank. Check for a leftover staging setting. |
| Viewport tag | No mobile viewport tag | Google indexes the mobile version of your pages first. | Add the viewport meta tag to the page head. |
| Load errors | 404 and 500 responses, redirect loops and timeouts | Broken URLs in a sitemap waste crawl budget and frustrate visitors. | Fix the page, redirect it, or remove it from the sitemap. |
HOW TO USE IT

COMMON CAUSES
TIMING
Run one after every redesign, migration or major plugin change, because that is when technical problems are introduced. Active sites benefit from a monthly check, and stable sites should audit at least once a quarter. Run it again after each round of fixes to confirm the problems are gone.

FAQ
A technical SEO audit tool crawls your website and reports problems that affect how search engines crawl, index and understand your pages, such as missing titles, missing canonical tags and broken URLs.
Yes. It is free with no signup, no email and nothing to install.
It checks as many pages as it can within about 90 seconds. Fast sites often get several hundred pages checked. If the limit is reached, the report tells you that not every page was checked.
It looks for a sitemap referenced in robots.txt, then tries common sitemap locations directly. If neither exists, it falls back to scanning the links on the homepage.
For each page it checks the title tag, meta description, H1 headings, image alt attributes, word count, canonical tag, noindex directives and the mobile viewport tag. Pages that cannot be fetched are listed as errors.
A page can fail if it blocks automated requests, returns an error such as 404 or 500, redirects in a loop, or takes too long to respond. Those pages are listed as errors instead of being skipped silently.
No. It covers on-page and technical basics across many pages. A full audit also covers Core Web Vitals, indexing status, JavaScript rendering, redirect chains, internal linking and server logs.
Run one after every redesign, migration or major plugin change, monthly for active sites and at least quarterly for stable ones.
Yes. Use the Export CSV button to download every page with its issues, title, meta description length, H1 count, image and word count data, so you can share it with a developer or client.
No. It fetches public pages to run the checks and does not save the pages or the results. A short-lived counter per connection is kept for rate limiting.
