Assuming that a Web page has a content that has an indexing potential with the major search engines then the single most important part of that Web page is the Title. This is not only the opinion of this Web site's webmaster, but also the opinion of many. There is wealth of knowledge available on the Web about this single Web page element.
The general view on the use of the Title tag is to make it informative and attractive while containing at least one occurrence of the Web page's most important keyword or keyword phrase. Webmasters that maintain an ever-growing Web site can write the Title using a pattern that has proven well for them.
As an example, the first part of the Title is the name of the Web site, the next part is the theme of the sub section and the last is a phrase about the Web page's content. One more thing to consider is the attractiveness of the Title as it appears within search engine results. Titles can easily help in getting to a prominent position within search results while not attracting visitors relative to that position.
On the Web sites we study, the average title length is 57 characters and approximately 8 words. This is within the range of title length considered appropriate for search engine optimization. Titles on the so-called Web 2.0 Web sites are considerably shorter averaging only 42 characters and 6 words.
