Working with ~100,000 products. Currently the way I'm using has the following priorites (most to least)Model information such as name and model number of a given product Product line's associated keywordsThe site's global keywordsIs this a good way to generate quality meta tags and content? Should globals be more prominent or is it best to prioritize what makes each page different?
What keyword should come first in a product page's meta tags?
seo;keywords;dynamic;meta tags
Since meta tags have no influence on your page's rankings, but can be used in a page's listing in the search results, I would make sure the description tag is written like a sales piece. It can be the deciding factor for users when deciding which search result to click on. The keywords tag is obsolete so I wouldn't worry about the order of the keywords in there.
