Title tag
The text displayed in the blue bar at the very top of the browser window, above "Back," "Forward," "Refresh," "Print," etc. Although inconspicuous to the user, the title tag is the most important bit of text on a web page as far as the search engines are concerned. Search engines not only assign the words in the title tag more weight, they also typically display the title tag in the search results, making the title tag an important potential call-to-action as well. Thus, the wording of each page's title tag should be thought through carefully. Also see "keyword prominence."
