Well I’ve finished a spreadsheet determining keyword eCPM for all the domains I own. I’ve also determined competition based on allintitle and allinanchor searches. This has given me some direction on which sites to develop first.
I have created a simple site template that is optimized for high clickthrough rates with Adsense, as well as good SEO practices. Using this template I’ve developed the first mini site. It’s a mini site, meaning there are only a few pages and it’s not a full CMS that allows to easily add content. It might be enough of a site to get indexed and rank for some keywords. If each site can bring in some traffic and create a little income to pay for itself, then I can focus on fully developing the core sites I own.
