Hello, Should we take the CPC too seriously when doing niche research?? This came to my mind after these 3 things... Reading This When I only see domain/seo/hosting related ads on google display network. When I tried a less cpc keyword and got more cpc after the site ranked. Now the thing is that google puts in a cookie for every visit you make and that cookie is sent to google regularly. The cookie has the web urls we visit the most and then google decides the relevant ad category and shows the visitor ads of their interest. Now you go to your own niche site and see the ads will not be related to the niche but to what you search.. With this I learned 2 things: 1st that cpc doesnt matter when you do niche research 2nd that the ctr goes down because of this. Why ctr goes down because of this is because the user already knows about the website they are advertising and when user knows about the website why will he click on the ad. What you think on this...? I maybe wrong.. Just want to discuss and make my thoughts clear.. Thanks and Regards EDIT: You can open http://www.google.com/ads/preferences to find out that the ads shown to you are from which category and you can edit them..
