What is Linkdex?

Linkdex is an enterprise-class platform that combines team management software with search engine optimization tools. Sometimes we crawl websites to understand backlink profiles or gather information for our users so they can improve their websites and SEO strategies.

Why have you crawled my website?

Unlike some crawlers, our bots don’t randomly trawl the Internet for information. We only crawl pages which our users deem relevant.

If your site has been crawled, our bots will appear in your analytics/server logs with the following details:

Responsible Crawling

Linkdex will respect the crawl frequency limitation you have outlined in your robots.txt file. We also crawl relatively slowly, often waiting up to 5 seconds between pages. This ensures your website’s performance is not affected in any way.
