Edit

Can I spider multiple sites in the same crawl? Is there a limit to the number of seed URLs?

Yes, you can crawl multiple sites in the same Crawlbot job: simply add each seed URL, separated by a space, when creating or editing your job. Crawlbot will then apply any crawling and processing patterns (and/or regular expressions) to all of the domains/subdomains contained in your seeds.

Extracted content will be indexed in the same Crawlbot collection; you can use a Search API query to filter by site (query=site:diffbot.com) if you’d like to narrow results after crawling.

There is no hard limit to the number of seed URLs.
