Hello, Lately I see al lot of adwords ads from google on my websites. I want to block them in my adsense account because they haven't anything to do with the subjects of my websites. But blocking ads from your own account provider scares me a little. Isn't it strange to block it? Greetings website2014
It's most likely just the targeting to you specifically since I assume you look up a lot of advertising things on Google. It doesn't mean that your visitors will see the same ads.
The ads you can see are different than what your visitors see. They are highly targeted ads and depend on your browsing history. So as long as there are not more than 3 banners on a single page and the page does not look too "bombarded" with the ads, I guess its OK to have them on your website or you can simply reduce the number of ad banners on your page so make it look more content oriented rather than ads oriented.
