To begin with, there are a few elements, a search engine looks at when examining a page. After the URL of a site, a search spider records the site title. It also examines the description meta tag. Both of these elements are found in the "head" section of the source code.
Titles should be written using the strongest keyword targets as the foundation. Some titles are written using two or three basic two-keyword phrases. A key to writing a good title is to remember that human readers will see the title as the reference link on the search engine results page. Don't overload your title with keyword phrases. Concentrate on the strongest keywords that best describe the topic of the page content.
The description meta tag is also fairly important. Search engines tend to use it to gather information on the topic or theme of the page. A well written description is phrased in two or three complete sentences with the strongest keyword phrases woven into each sentence. As with the title tag, some search engines will display the description on the search results pages, generally using it in whole or in part to provide the text that appears under the reference link.
