I agree with ecmedia and reno. In fact SEO service companies are dead and have been for a couple of years.
There are a few rules to follow first off - titles, keyword repetition, experimentation with ad formats, keyword rates etc. All these are available free of charge from this forum.
Any further analysis is pointless if you are in the business for the long term. Just produce good content, stick with it and manna from heaven will eventually come your way. Break those basic rules and you will eventually fail.
I am amazed that people pay good money to SEO companies rather than rely on their own judgement.
Every SEO company I've ever been in contact with use words and phrases which are jargon. Analyse the sales pitch, examine those words very, very carefully and consider what they mean. Most times they are junk.
When some guy comes along and says I can double your earnings and will only charge you half of that increase when it happens, then stop and listen. When some guy comes along and says I can double your earnings (probably, but this is a complicated subject) and I want half of the projected increase up front, just walk away. I have never met the first guy.
