Common questions

Can Web Crawler extract dynamic pages?

It depends on how the target page renders content and whether the site exposes accessible HTML or APIs.

Why is the crawled result different from the browser view?

The site may vary output by login state, region, User-Agent, JavaScript execution, or anti-bot behavior.

What compliance rules apply to web crawling?

Only crawl content you are allowed to access, and respect site terms, robots rules, copyright, and local laws.
