Free Website Health Checker

Analyze any page for 189 checks across SEO, security, performance & accessibility.

Enter a URL above to get started.

What the free website health check looks at

Paste one URL and Dr Urls fetches that live page, then runs 189 checks against it across four areas. Every problem found is ranked by how much it matters and comes with the exact fix. No account, nothing to install. The free check covers the one page you enter; a full audit crawls the whole site.

SEO93 checks

A technical SEO exam of any URL: crawlability, indexing, metadata, content and structured data, ranked, each with the fix.

Performance51 checks

Core Web Vitals from PageSpeed Insights, plus every render-blocking resource, oversized image and layout problem, ranked.

Security22 checks

HTTPS, security headers, mixed content and cookie flags on any URL — each weakness with the exact setting to change.

Accessibility23 checks

Missing alt text, unlabelled controls, broken headings and contrast failures — the problems search engines and lawyers notice.

How it works

  1. Step 1

    Paste a URL

    Any public page: a homepage, a product page, a landing page you are about to launch.

  2. Step 2

    We examine the live page

    The page is fetched as it is served today, headers included, and every check runs against that response.

  3. Step 3

    Fix what matters first

    Issues arrive worst first. Copy the list as a brief for your coding agent, or start a full-site audit.

Questions

How do I check the health of a URL?
Paste the address into the box at the top of this page. Dr Urls fetches that page as it is served today and runs 189 checks on it — SEO, speed, security and accessibility — then lists every problem worst first, each with the change that fixes it.
Is the website health check free?
Yes. Checking a page needs no account and no card, up to 3 checks an hour. A free account adds 5 full-site audits a month, each crawling up to 50 pages rather than one, and keeps them in your dashboard.
What is the difference between this check and a full audit?
This check examines the one page you enter. A full audit crawls your site, up to your plan's page limit, runs the same checks on every page, and adds the ones that only exist across pages: duplicate titles, descriptions and headings, internal links that land on an error, a missing or unreadable sitemap, and, when it reaches the whole site, pages your sitemap lists that nothing links to.
Can I hand the results to an AI coding agent?
Yes. Every result can be copied as a Markdown brief that lists each issue with why it matters and the exact fix, ready to paste into Claude Code, Cursor or any agent.

Every issue the check can report has its own explanation and fix in the issue guide, which covers 235 issues in all.
