But not all the time so, in many cases ads are irrelevant, for example I have a marketing site and sometimes appeared me ads for travel agencies, this is counterproductive to my Adsense business, since the visitor sees this as unprofessional, and that at that time visitors this interested in something else, not going on holiday so it will not click on those ads.To avoid these problems, we have to create URL s with the keywords of our niche, so be avoided to minimize the occurrence of irrelevant ads. Step 3: Use the correct colors, we must understand the psychology of colors, choose the correct colors and increase the CTR of our site, choose the wrong combination and visitors will leave your site more quickly that he sings a rooster. I leave you some rules to follow: 1.-uses light colors like white, blue background light or light green, are the best colors to use as a background. You can use any other color if you prefer, but make sure that you are clear versions. 2 Usa blue color for the links of ads adsense, for some strange reason this strategy works miracles, any other color in the adsense links have better CTR to blue color, it is as if our mind would have trained for this.
