The title tag is important !
One of the most important actions that you can take to make your site more visible to the search engines is to incorporate key words in your title tag. Sometimes you will find title tags "Welcome to our site" or something similar, while the content of the page is to f.eks, to sell IPOD’s or other elctronics.
In that situasjon, this is not a correct title tag as no one is searching for "Welcome to our site". Use the key words found in the research and strategy. If your site is about widgets, then the title would include your key words using widgets
title tag Definition
HTML tag used to define the text in the top line of a Web browser, also used by many search engines as the title of search listings.
A title tag belongs in the HEAD section of a Web page, above the BODY section. Technically, it may be above or below the
The information contained in a title tag appears at the top of the Web browser when viewing a Web page, and at the top of (most) search listings.
Writing descriptive title tags is an important part of optimizing a site to rank well with the search engines (and get clicked by visitors). A well-crafted title tag can stand on its own without the benefit of the accompanying page content, as this is how it appears to Web searchers who know nothing about your site.
Include at least one targeted keyword or phrase, maybe more, instead of using all generic words that do not distinguish your page. If possible, keywords should be used early in the title to help search engines and visitors identify the main subject of the page, and also to avoid getting cut off by search engines that use relatively short titles. Search engines have limits as to how many characters are used from the title tag and typically display between 50 to 70 characters.
