Technical SEO

Crawler

Also known as: bot · web crawler · spider

A program that automatically visits pages and files to find information or collect data.

A practical example

Googlebot retrieves a public product page.

What should I know?

Not every bot follows the same rules, and not every bot is a search engine.

Technical SEO in practice

Check crawler access, server responses, and content processing separately. Then assess indexing and search appearance. These stages are connected but distinct and need different diagnostic methods.
