SEO firms do not have special relationships with Google. Why would they? Google’s major source of income is advertising programs like adwords. It’s unlikely that they would give away trade secrets as to how to get free advertising on there search results pages. Google does however give a set of strict webmaster guide lines that SEO firms must follow to be included in there index. Breaking these guidelines will result in a decrease in search positions or possible expulsion from the engine. Any techniques that are against Google’s webmaster guidelines are called black hat techniques. Search "TrafficPower" for evidence!
