More Backlinks from Ezinearticles

I have now also published the other 2 topics on ezinearticles.com.
Here are my articles which have a backlink to both of my squidoo lenses:
PPC Optimization
Google Adwords Guide

I link from both of the articles also to both squidoo lenses, so I get 2 backlinks for each squidoo lens. As you know, backlinks from high page rank sites (ezinearticles has a PR of 6) are quite important, so I hope that those links will help my lenses on the search engines.
