The central goal of Injection is to automatically produce high-quality META tags for all of your web pages. For the uninitiated, META tags are special HTML tags embedded in the HEAD section of a web page. These META tags provide 'meta' info for the page.
Meta information is information about information.
That is, the META tags can provide information like who authored the page, when it was produced, or even a short abstract of the page. This is where Injection comes in. Search engines rely on META tags, specifically keyword and description META tags, in order to index your page. Since search engines are so widely used on the Web, creating content specific META tags using Injection will bring more interested visitors to your site. Publications can keep track of a page's author, date of creation, modification, etc.
