The internet industry loves to create an air of mystery around SEO as some kind of amazing skill. The reason this is done is that it is actually quite easy to do your own with the correct discipline. If you have a nice and easy manouverable website good site map clean categories and well labelled pages and sort your Meta tags and content out accordingly over time you will have as much success as paying someone. How do I know this? I've done it myself on 4 websites with equal measures of success each time an never paid one cent for SEO or Adwords ( which does not improve SEO). I dont know nothing about SEO per sae, I know about structuring a website well and making sure I have highly relevant key words with a good stie structure. That is all!

Of course most people go for cruddy freebie websites with poor Content Management Systems and Structure and dont set them up well....hence they fail.

It's worth spending a bit more on getting a professional developer to build you a decent site and structuring it correctly rather than doing an on the cheap site nobody can find.
