The page title is metadata located inside the page head. It should describe your page content. Page titles are used by search engines and also displayed on the page tab. The traditional format for an SEO-friendly page title is as follows:
<tt>Primary Keyword - Secondary Keyword | Brand Name</tt>
It is recommended that the title should be no more than 50-60 characters (including spaces). It is very important that the page title accurately describes your content. The title will display when people share your page and when your site is queried by search engines.
