A free website audit tool checks your site for the technical issues that quietly hurt rankings and user experience — broken links, missing meta tags, and more. Here’s what a good audit actually checks, and two free tools you can run right now.
What Is a Website Audit?
A website audit is a systematic check of your site’s technical health — the things that affect whether search engines can crawl and rank your pages, and whether visitors have a smooth experience once they land on them. A basic audit typically covers three areas: on-page SEO (titles, meta descriptions, headings), site structure (URLs, internal links, broken links), and site-wide foundations (sitemap, robots.txt, HTTPS).
It’s different from a full SEO strategy. An audit doesn’t tell you what to write about or which keywords to target — it tells you whether the technical foundation of your site is solid enough for that content to actually get found.
Why You Should Audit Your Website Regularly
Websites don’t stay static. Pages get added, renamed, and deleted. Plugins get updated. Content gets migrated. Every one of those changes is a chance for something small to break — a link that now 404s, a page that lost its meta description, a heading structure that got scrambled during a redesign.
None of these issues will crash your site. What they do is accumulate, quietly, until a site that used to rank well starts slipping for reasons that are genuinely hard to spot just by browsing it yourself.
What a Good Website Audit Actually Checks
Here’s the core checklist most technical audits — free or paid — are built around:
| Area | What’s Checked | Why It Matters |
|---|---|---|
| Titles & meta descriptions | Missing, duplicate, or wrong-length tags | Your first impression in search results |
| Headings (H1s) | Missing or multiple H1 tags per page | Helps search engines understand page topic |
| Images | Missing alt text | Accessibility + image search visibility |
| Links | Broken internal and external links | Wastes crawl budget, breaks user trust |
| URL structure | Case, underscores, length, canonical tags | Clean signals for both users and search engines |
| Site foundations | robots.txt, sitemap.xml, HTTPS | Whether search engines can find and trust your site at all |
Run a Free SEO Audit
Paste your URL below and our crawler checks the first item in the table above — titles, meta descriptions, headings, alt text, canonical tags, and site-wide foundations — across up to 20 pages of your site.
We will crawl up to 20 pages and check for common SEO and URL issues. This can take 20-40 seconds.
Run a Free Broken Link Check
Broken links get their own dedicated checker, since a thorough link check means testing every single link found — not just the page it’s on. Paste your homepage URL below and we’ll crawl up to 25 pages, checking every internal and external link for a working response.
We'll crawl up to 25 pages of this site (starting from the homepage) and report every link that returns a 404 or fails to load. This can take 20-60 seconds.
🧰 Prefer both tools on one page?
Our Testing Tools page runs the SEO audit and the broken link checker side by side, so you can test everything in one visit.

For most small business and marketing sites, a quarterly audit is a reasonable baseline. Run one immediately after any major change too — a redesign, a content migration, a switch in hosting, or a bulk cleanup of old pages. Each of those is exactly when broken links and missing tags tend to appear.
- E-commerce or high-traffic sites: monthly, since product pages change constantly
- Content/blog-focused sites: quarterly, plus a check after any bulk edits
- Any site, after a redesign or migration: immediately, before and after launch
Frequently Asked Questions
Is a free website audit tool as good as a paid one?
For the core technical checks — titles, meta tags, headings, broken links, site foundations — a free tool covers the same fundamentals as most paid platforms. Paid tools generally add scale (crawling thousands of pages), historical tracking, and deeper competitive/keyword data.
How long does a website audit take?
A browser-based audit of a small to mid-sized site typically finishes in under a minute. A full manual audit with strategic recommendations takes longer — usually a few hours to a few days, depending on site size.
Do I need to sign up to run a website audit?
Not for a basic technical check. Both tools on this page run without an account — paste a URL and get results directly on the page.
Will running an audit slow down my site?
No. A crawler makes standard page requests the same way a normal visitor or search engine bot would, at a controlled rate — it won’t affect your site’s performance for other visitors.
You don’t need a big platform or a monthly subscription to know whether your website’s technical basics are in order. You need ten minutes and a URL bar.— Testionix Team, Ahmedabad
