META Tags and Search Engines
META Tags are hidden away in the <head> section of the coding of every web page.
Some META Tags have search engine relevance - these are the META "Description" tag and the META "Keywords tag.
Other META tags, although they exist and can be used correctly, offer no search engine advantage at all. Indeed, incorrect use of these META tags may lead to your web pages being penalised.
There's no reason to ever use the META revisit tag. A search engine will not revisit your page in 10 days just because you tell it to do so in a Meta tag - to get robots visiting your page on a more regular basis, work on "content freshness" and consistantly add new content to your Web site.
Look closely at the <head> section of your Web page.
The subject, author, copyright, and publisher tags are NOT meant to
be used as
places to stuff keywords - search engines may see this as spam. Never put keywords into
these tags in an attempt to influence ranking - better to get
rid of the tags
altogether. They're not needed on your pages, even if you do use
them correctly.
