How Search Engine Spiders See Your Page – The Short Answer
Website checkers find technical problems – expired SSL, broken links, missing compression and content crawlers cannot read.
The checker sends a request to your website like a browser or search-engine crawler would. It reads the server response, headers and page content, then reports what it finds along with problems to fix.

| Check | Healthy result | Why it matters |
|---|---|---|
| SSL | Valid, not expired | Trust and HTTPS ranking signal |
| Compression | GZIP or Brotli on | Faster pages |
| Links | No 404 errors | Better user experience |
| Crawlability | Text readable by bots | Content can be indexed |

- Enables HTTPS and encrypts data between visitors and your site.
