Meta Tag Editor
The Meta Editor helps to create or edit the META tags for your web pages. Meta tags are HTML tags that don't appear on a web page, but provide information that describes the content of a web page. Meta Tags are used by search engines to help index and rank web sites on the Internet. If a page doesn't contain META tags, some search engines create a description and a keyword index based on the first few lines of text on a page.
Additional meta tags can be toggled by selecting the advanced checkbox.
