Just lately I seem to have received a spate of junk mail from companies promoting their search engine optimisation services. How to top Google rankings and avoid paying the sponsored link or advertising fees is the know-how they are touting. Well for my money, I have noticed that Google services like Blogger always seem to get a good weighting in the Google algorithms (how surprising) so a good start would be to have a blog in blogger with all your key words in. It certainly works for me. Secondly, it makes sense to update your pages regularly as I mentioned in one of my very early blogs.
The second thing I have had to deal with is loads of Anonymous comments appearing as a result of some dodgy spiderbot roaming the web; for some reason it particularly liked the one with a title using the Cyrillic alphabet.
