Quick update....
My minisite until today has zero
SEO / Back link / etc. which started as a test. The site for some reason does not receiving traffic from Google buy gets all known SE hits via Yahoo.
I picked a strange (banking) area but had the backend data available for the unique sticky content. Problem was until I started the domain didnt know if anyone was searching. Today am lucky to attract between 7 - 32 unique hits a day which finally makes over my $5 a week target (£0.50 a day).
I would say the only thing keeping the site alive is the unique content and close keyword usage in domain name. The domain hlq is irrelevant so is the hosting server as its been hosted within the US / Canada and UK with no change.
Site uses no header meta data which will change at some point. But have started to expanding with five similar domains to capitalise on rank by domain keyword. Each site will use same backend but has different site template.
If half the domains hit my $5 target, I will start link building if anyone is interested pm. As for flooding a niche, is this the best way forward for a minisite?
