On pages I publish, I have adsense display ads, which often seem to show "follow me" or "remarketing" ads (relevant to the user's recent searches) rather than contextual ads (those relevant to the page in question). My ad block in this case is 250x250.
How can I reduce the number of follow me ads, and get more page-relevant ads to show?
This is deep content site, and each page is definitely about a specific topic.
