People use the search engines in twodifferent ways. One is for research purposes and the other is for buying purposes.
Key phrases used by people researching are typically
different to those used by people looking to buy. Therefore the SEO on your site should reflect the type of visitor you want.

Someone using a search engine to look to buy a Paul Frank belt is likely to use a term like Buy Paul Frank Clothes or Buy Paul Frank T-shirts as these are likely to produce results from companies that sell Paul Frank merchandise. If they were researching into the business or the designer then terms like About Paul Frank Industries or Paul Frank Designer would be used.

This is not the case for all keyphrases though. If a user already knows the product id number then they may use that to search for their desired product. Someone searching for a Vitalograph Emergency Aspirator might use the keyphrase (M1830) Vitalograph Aspirator as it includes the product number. This should return web pages with the specific product on so it is easy for the user to compare prices.

Some keyphrases can attract both types of visitor. These are keywords that will be input by both types of user.Terms like Web Design Wiltshire and Web Design Salisbury would be used by people researching web design companies in the local area. Some one who is looking to hire a web design or search engine optimisation company is likely to use these terms to.
