Right,

Have taken over one website recently and after changing the ads to appear more like the content my was up significantly.

I just changed the ad links to be more like the rest of the website still has add by google etc, i dont want to get banned by google etc is this okay to have ads looking similiar to site to blend in i read that it increase ctr but this is a big CTR increase.

Its a health information site by the way and top three in google for particular keywords.
