When building links to your website, it is very important to check if your links don't have nofollow attribute.
For Google and other search engines, nofollow means that link won't improve your rankings, it won't transfer any PageRank.
A nofollow attribute looks like this:
<a href="[link]" rel="nofollow">[anchor]</a>
