I find that the Adsense ads on my blog does not match the content. My posts can be on technology, yet the Adsense ads are on starting a blog or wordpress themes. How can I get the Adsense ads more refined to match the content of the site? Thank you
It is possible to sectionally target your ads - eg. make them apply to only one part of your blog content. Can you tell us what your blog URL is?
It is normal especially if your blog is newly created and not yet fully indexed by G. Add more content that is closely related to your topic or you may try ilfilosofo's plugin.
It is indeed typical. What you can do other than targeting specific areas of your site is to block those sites that don't match. Go to your adsense control panel and add those sites to the competitive filter (originally designed to prevent competitors from advertising on your site, I think). Adsense usually takes a minute before it is perfect, and even then youll get some random ads from time to time.
