Site Audit
A technical SEO audit that tells you what changed.
Seylio crawls your site every week and groups what it finds as Errors, Warnings and Notices. For every issue you see the affected URLs, how it developed across earlier audits and how to fix it.
Weekly, automatically
Every active project is crawled once a week, so new problems surface days after a deploy, not months.
New, recurring or fixed
Each issue shows its history, so you can tell an old known problem from something your last release broke.
Every affected URL
Open an issue to see exactly which pages are hit, with the evidence Seylio found on each.
Guidance with every issue
What the issue is, why it matters and how to fix it, written for people who are not SEO specialists.
What the audit checks
The crawler renders your pages and records what search engines and AI crawlers see. Findings are grouped by severity so the urgent ones are never buried under notices.
- Crawlability and indexability: status codes, robots directives, canonicals and noindex.
- Titles, meta descriptions and heading structure.
- Internal and external links, broken links and redirect chains.
- Structured data: missing, incomplete or invalid schema.
- Images: missing alt text and dimensions.
- Performance and Core Web Vitals, when field or lab data is available.
- hreflang for multilingual sites.
History per issue, not just a score
A site health score on its own hides what moved. Seylio keeps the result of every audit, so each issue carries a small trend line and a status: new, declined, improved, unchanged or fixed.
At URL level it goes further: a page that was fixed and then broke again is marked as regressed. That is usually the clearest sign that a template change or plugin update undid earlier work.
Category scores that add up
The overall score is built from weighted categories such as content, crawlability, meta and titles, structured data, performance, AI visibility, rankings and images. You can see each category, its weight and its change since the previous audit, so the total is never a black box.

Good to know.
How many pages does Seylio crawl?
That depends on your plan: from 1,000 crawled pages per project on Starter up to 25,000 on Agency.
How often is my site audited?
Every active project gets a new audit every week. A new project is scheduled for its first audit within about an hour.
Does the crawler change anything on my site?
No. The crawler only reads pages, the same way a search engine does.
Can I export the issues?
Yes. Every issue list can be exported as CSV or Excel, and a full export bundles all reports in one ZIP.
