Adsense shows irrelevant ads on my blog. In the last two days my gadget blog shows only health related ads. you know, ads about shark liver oil or how losing fat etc. Yeah, I wrote a health related post about 18 months ago, but now suddenly all my post shows this health ads. Any clue why this happen ? Should I contact Adsense team ?
Of course you should if you're getting irrelevant ads continuously. Recently, irrelevancy in ad targeting has become a serious issue.
Couple of things you could try: Try removing the ads for a month - see if they "reset" after that Use section targeting Contact Google
