I have a loan site and its 5 months old. The loan ads I have before are very relevant and am happy. But today I have seen "web hosting" ads through out my loan site. Only one page is filled with loan ads. Others are web hosting ads. Why this would happen?
It could be a couple of things. One, Google is/was making some small changes to the Adsense/Adwords Algo, and you got some weird results. Second, there aren't enough mortgage/loan companies buying ads, so Google is pushing out other ads to those sites. The second is most likely, considering the fiduciary mash-up going on in the financial markets, especially for mortgages.
That is because your content may be relating to web hosting. Check the frequently using keyword for your pages. The adsense shows ads they have most and not the most appropriate for your site. They show the ads if any keyword for the ad is present on your site.
You mean your site is 5 months old or you have had ads for 5 months ? if you just put ad's then it might be the reason Google takes little time to send you relevant ads. Also check the keyword density of the page.
