SEO was an accident, as I think it is for most people. I know no-one who grew up thinking I want to be an SEO consultant.
Anyway I was staying in Prague one very cold winter and woke one morning thinking I should know how to build a website. So I built this site http://www.caminodesantiago.me.uk/ on the Camino Frances.
As you would expect only my friends saw the site and I started trying to see why I was not in the front page of Google for my great site, hence SEO. Now 100 sites later I run my own consulting business http://www.cubeonlinemarketing.ie/ - but my long term goal is living from my own sites - more than half way there so far.
