Install the Meta Tags Module (AKA Nodewords) in order to update the META description and keywords tags. The description META tag helps give crawlers an idea of what the page is about, but it is not the description used by most search engines (including Google) for describing the page in search results listings. It is important to create unique description META tags to improve the page rank of your pages. The keywords META tag is supported by very few search engines (and not supported by Google), so it makes sense, in most cases, to not bother with entering keywords META data. The robots META tag is used to tell robots not to index a page: . No tag is necessary to get crawlers to index a page - by default they index any page they can find. Note that the robots.txt method of preventing a page from being indexed is more efficient, as you don't need to add a tag to every page. Although the header is the logical place to include keywords, it is also important to include them in your page content. Even search engines that don't place more weight on keywords in the header use keyword frequency in calculating a page's overall score. Sprinkle keywords, and their synonyms, liberally throughout the page content and inside HTML code.
