Welcome to the Q&A Forum

You've not got that much in terms of link diversity, or from much that's relevant. Directories, blogs and forums, links pages, etc... that don't pass a lot of value. 11 Linking Root Domains, including directories, some are nofollow. Not a lot in terms of quality links. And then your anchor text needs a little more diversity too: http://www.opensiteexplorer.org/www.nintendowiifitconsole.co.uk%252F/a!anchors Google will often let a new site rank well for a bit before knocking it back down again. Also, my personal belief is that Google's not all that keen on affiliate sites anyway... I lost rankings on mine from Panda. I reckon all in all, if you get some more, higher quality links... and as it appears now some social signals too, then you'll start ranking much better

Ah ok I get it...sorry I am a little slow! Thanks for your help and I will appy that method to remove  the cat. links.

One quick aside: categories in WordPress are easier to SEO then tags.  Wordpress collects category descriptions.  Plugins like All In One SEO Pack can use this info to write a meta description for you.  Wordpress doens't collect descriptions for tags so plugins can' use this info to write out a meta description for your tag pages.
