Every issue the scanner finds, organized by category
Every entry below maps to a specific finding the scanner emits — there are 451 of themat last count, growing roughly weekly as scans surface new patterns. Each page covers one issue: what triggers the finding, why search engines or users care, the typical root cause, and a copy-pasteable fix with a code example. The fixes are written to be specific enough that a developer can ship them without further research — not generic "improve your SEO" advice.
Crawlable issue pages with root causes and fixes.
Built around the main issue types site owners search for.
Critical and high-severity problems that deserve fast action.
How the library got built
When the scanner first emits a brand-new finding type, the catalog grows automatically: a background job (gpt-4.1, costs about $0.02 per draft) writes the first version of the page from the finding's description, fix recipe, and tags. Then it's reviewed and edited before going live. As of the last build, that pipeline has produced 451 published issue pages across 10 categories, with new ones added every week.
The category split (security / performance / technical SEO / on-page SEO / crawl & links / best practices) maps to how I think about SEO triage in practice — if I'm looking at a site that lost rankings overnight, my first stops are technical SEO (canonical bug? robots change?) and crawl & links (404 cascade? sitemap error?). Browse to the category that matches your symptom, or search by issue title from the search box.
