A clever affiliate link technique (clever does not imply ethical).
It looks like we found a large part of our problem with our Google traffic so I thought I would share it here since it probably is not the paid links though we are still planning on removing them if we are not allowed to nofollow them.
Many of our top search results now have Pinterest boards listed above them now.
That seems normal since Pinterest is pretty awesome. However, this is for free things that teachers and students and retirement communities like to use.
When you click the pins on these boards you go to a page that has a pretty picture and says 'Click here for the thing you wanted' (note it does not say free in this anchor text like it did on Pinterest).
Clicking the link sends you through an affiliate link to purchase the supposedly 'free' thing LOL.
It appears to take advantage of the Google algorithm putting more weight on the title of the Pinterest page than on the actual content that it leads to.
I'm sure this will be caught soon but I was amazed at how many number 1 results on Google were Pinterest pages using this technique.
