What an audit covers
squirrelscan checks your site against 249+ rules across 21 categories. Here are the areas it covers.
SEO and crawlability
Meta tags, headings, canonicals, robots.txt, sitemaps, and internal link structure. The fundamentals search engines read first.
Performance
The rules behind Core Web Vitals: render-blocking resources, oversized images, layout shift, and slow responses.
Security
HTTPS, security headers like CSP and HSTS, mixed content, and signs of compromise across every page.
Accessibility
Alt text, contrast, labels, and structure so your pages work for real users and assistive tech.
Content and structured data
Readability, thin or duplicate content, Open Graph, and schema.org markup for rich results.
Agent experience
llms.txt, clean markup, and the signals AI crawlers and answer engines use to read and cite you.

Frequently asked questions
- What does a website audit check?
- squirrelscan runs 249+ rules across 21 categories: SEO, crawlability, performance, security, accessibility, content, structured data, and agent experience. It crawls your whole site, not just one page, and reports issues with fixes.
- Is it free?
- Signing up is free, and every account gets a free monthly credit allowance for cloud audits. Local audits with the squirrel CLI are always free and unlimited. Beyond the monthly allowance, cloud audits are pay-as-you-go, so you only pay for what you run.
- How long does an audit take?
- A typical audit finishes in a few minutes. Larger sites take longer because there are more pages to crawl and score. You can watch progress live from the dashboard.
- Do I need to install anything?
- No. You can run a full audit from the dashboard in your browser, nothing to install. If you'd rather run audits locally or inside a coding agent, install the squirrel CLI with a single command.
