New project update

Progress Report:
I have begun by creating three pages on a common template to give a degree of continuity which hopefully creates a more professional appearance... I have gone through some basic steps such as adding keywords and title tags to the pages and have implemented some monetisation.
As would be expected, I have added an Adsense side-bar to each page, but have yet to insert any adverts within the text areas which I intend to do eventually. I have also signed up as an eBay partner and have added some eBay banners to the base of each page (the pages are only short) - I have been pleased with the way that the you can configure the eBay banners with chosen search terms - this has enabled me to show eBay items which are linked to my content perfectly. I plan to use these on some other sites (must remeber to ask admin if I have to get each site approved..).
I am reconsidering the domain issue as I am not sure how easy is it going to be to generate organic traffic without the added bonus of a domain which mentions my chosen keyword.
On site SEO stages that I have completed:
Using keyword tags, tagging pictures, title tags, content, using anchor text to link between pages (not yet created a navigation bar...), used keywords in the URLs.
On site SEO yet to be completed:
Buy a suitable doman and cheap basic hosting, cram more information and relevant content into the existing three pages.
Off page SEO completed:
Used anchor text from other sites to link to my home page.
Off site SEO yet to be completed:
Look for other places to leave links and anchor text, maybe blogs and forums would be a good place to start - but really should get a domain first rather than be left with links pointing to an unused site...
Other tasks:
Create a nice nav bar to fit with the theme, could be fairly large as there will not be many pages. Plan out extra pages - advice on changing a CPU, information on fans and heatsinks/thermal paste etc...
As you can see from the time delays I am not exactly full-time at this, and the fact that I am hosting this on one of my own sites is probably the reason for my lack of urgency - ie. it's not costing me anything - I would be sure to be on the case if I was paying for hosting...!
I will do some comparisons and maybe go ahead and buy myself a domain in the next few weeks (I have a stash of PayPal money at the moment...). As ever I have a list of pressing issues with very little time in which I can get them completed - I must set myself some targets..
