Keywords are no longer merely a long list of words contained within the ‘meta keywords tag’ at the top of your html. In fact many SEOs advise against using the meta keywords tag as it can easily be read by your competitors and Google has declared (along with other search engines) that they no longer use them for ranking your site. Therefore the use of keywords has developed into more subtle methods.
I use a combination of various tools including Google’s keyword tool in order to analyze your keyword strategy. Once I have analyzed your keyword strategy, I can produce a comprehensive list of keywords you should be targeting, and keywords your competition is targeting. This list alone will be invaluable to your business.
