I received a $100 USD AdWords promotion but I don’t think that it would be at all useful for a site that generates income based solely on AdSense.
The site’s traffic base is made up mostly of search engine traffic and the repeat visitor base is quite small.
Search engines: 57%
Referring sites: 35%
Direct traffic: 8%
Repeat (returning) visitors: 15%
I have no idea what each click would cost me but guess that my $100 credit will be consumed fast, and not worth the small amount of repeat visitors that I may gain.
What are your thoughts?
