First of all I would attempt to make a search on all search engines employing relevant keywords and keyphrases, I am optimizing for. The analysis of results will say whether the methods of optimization have gained results or lost. I would analyze the report regularly as search engine makes updating and index. I would attempt to another aspect of website statistics which says about origin of traffic.
