Above statement pretty trivial.

But interesting that Google seems to use Alexa rank and produce Ad Planner data only for sites with Alexa Rank less than 100,000.

For example site http://www.familiararticles.com ranked 99651 on Alexa included in Ad Planner database, but site http://www.womenhealthexercise.com/ ranked 100,238 did not.

Possible to conclude that Google consider sites with Alexa Rank less than 100,000 not important at all? And use it in particular for backlink building planning?
