Will using in-text contextual advertising (such as Kontera or InfoLinks) have any negative affect on my Google PageRank? Actually I have a blog which I have just built up PageRank on. I don't want to lose that PageRank. Hence i wanted to confirm that Kontera or InfoLinks won't hurt my PageRank before starting either of them on it. So do let me know your experiences.
