When you assign a TYPO3 page a type of "Advanced" you have access the "Keywords" and "Description" fields allowing you to enter keywords and a description of the page to use in meta tags. However, to get them to show on the page you must add the following to your page object in your Typoscript template:
meta.keywords.field = keywords
meta.description.field = description
Which will make your page object code look something like this:
page = PAGE
page {
meta.keywords.field = keywords
meta.description.field = description
typeNum = 0
10 = USER
10.userFunc = tx_templavoila_pi1->main_page
}
Using keywords properly will help in your search page ranking.
