Page Title tags are important for your site. The page title should have relevance to the content of the site. For example if your page talks about Web Designers and Ecommerce Web Developers in Virginia then your page title should read ‘Ecommerce Website Developers and Web Designers Virginia’ The title on my first page is ‘Web Design and Computer Solutions, Ashburn, VA.’ This title is appropriate for my website because we are locted in Ashburn, are Web Designers and provide Computer Support in Ashburn and surrounding areas.
There is really no limit to how long you want your web page title to be, however Google only reads the first 66 percent of the title, Yahoo reads 95 characters and some versions support 95 characters.
