Welcome to the Q&A Forum

I am doing my best here Marc but I am not entirely clear on what information I can share that has not already been provided in this Q&A. Google crawls the web and adds web pages to its index. When a user performs a search query, Google then offers the "best" result based on numerous factors such as relevancy, quality factors, trust factors, importance of page, etc. There are over 200 metrics which are evaluated to determine ranking. One of those factors is the title. If a title exactly matches the searcher's query, then the ranking will benefit from that match as Google sees the page as more likely to be relevant. Does that help? If not, first try reading the following article: http://www.seomoz.org/learn-seo/title-tag. If you still desire help, please let me know exactly what information I can share that will assist you.
