A website health check crawls your site like a search engine, opens its pages like a visitor, and lists what is broken, slow or hard to use. SignalCrawler's free scan does both and gives you the results as a report with evidence, a prioritised plan and a bug list you can hand to a developer.
What it covers
| Area | Examples of what it finds |
|---|---|
| Indexing | noindex or robots.txt blocks on pages you want in Google, sitemap problems, soft 404 pages |
| Links and redirects | broken internal links, redirect chains and loops, links to redirects, broken images |
| Technical SEO | missing or duplicate titles and descriptions, canonical mistakes, hreflang errors |
| Mobile layout | horizontal scroll, overlapping and cut-off elements at ten widths, small tap targets and text |
| Speed | Lighthouse lab metrics on sampled pages and, where Google has them, real-user Core Web Vitals |
| Accessibility basics | missing alt text, contrast, keyboard focus, form labels |
| Trust and AI search | structured data, Open Graph tags, robots.txt rules for AI crawlers |
The most common findings across the 24 sites SignalCrawler audited in September and October 2026: unused JavaScript (22 sites), tap targets that are too small on phones (20), images without width and height (17), titles likely to be cut off in search results (18) and internal links to redirects (11).
What you get
- Findings with evidence: the affected URLs, the page template, screenshots for layout problems, and the measured values.
- A plan: findings grouped into tasks, ordered by impact and reach, with the trade-offs marked where a change needs a team decision or a test first.
- A bug list: a spreadsheet in the format testers use, with a status column and screenshots.
How it compares with free tools you may already use
PageSpeed Insights checks one page's speed; Search Console shows what Google decided about your pages; a desktop crawler lists technical issues. A health check combines the three views and adds what a person testing the site on a phone would notice. See free website audit tools compared.
