For getting good results with Adsense and even the Google Search Engine, which is best to use? A CMS? or build the site yourself?
The best thing to decide a niche, is just think of a good one, have no doubts and just start building the site. If you're going to think about it on and on you'll only postpone your earnings.
Me,I use CMS on iConsulting-first page on Google and WordPress for many-ex:Private Label Rights Club,no1 in Google,Webmasters Club,no 1 in Google,etc.All for the seach-name of the site!Is your decision and the hard work!
