The Meta Tags and Footer screen can be selected by clicking on the System Admin | Preferences | Meta Tags and Footer. Some of the options for this module are briefly described as follows:
Meta keywords are the keywords that best describe the content of your website. These can then be used by search engines to locate your website when search-engine users type in words that they are searching for. Each keyword is separated by a comma or a space, e.g. technology, education, free.
Meta description can be used to provide a short description of your website. This can also be indexed by search engines for later searching by end users.
Meta Robots tells search engines how to index your site for later searching on their websites. Index, Follow allows a search engine to index everything that is linked from the main website-index file. No Index, No Follow tells a search engine not to index anything on this website.
Meta Rating can be used to indicate any age-level restrictions...
