SEO is not something that I'd ever want to get into. At the end of the day your efforts are centred around trying to get the best out of a hidden search algorithm. There are guidelines for how to do it, but the algorithm and sites can change at the whim of the algorithm writers.
I've started using Google Webmaster Tools, and part of what it reports is which searches find your site. As it turns out, I must use the words 'touch' 'man' and the phrase 'how to' a fair bit throughout this blog, hence I'm scarily high up on the google rankings for 'How to touch a man.'
I found it amusing - has anyone else got funny search queries that return their site in the top 10? Please post below.
