Why does contentbird find less links than Google Search Console?

There are several reasons for this discrepancy:

1.) No backlink crawler can depict the whole internet.

The number of found backlinks depends on the time since when the crawler is active, as well as on the fact wether it has a certain focus , f.e. a geographical one.

2.) Sitewide links: saved only once in contentbird, because it does not make sense to monitor them all.

3.) contentbird only saves links that are online.

Especially 2.) and 3.) are important when comparing contentbird to Webmaster-Tools. Google Webmaster-Tools puts out all sitewide links and also links that are offline.
