Why does Extractor ignore the META tag in HTML?
The META tag in HTML is used to convey meta-information about the document, for example: Extractor ignores this meta-information. In particular, it does not use the “Keywords” meta-information. Extractor ignores the META tag for two reasons: (1) If you really care about the META tag, then you can easily write your own subroutine to parse it. (2) The META tag is widely abused. It is mainly used as a device for tricking search engines into giving a page a higher ranking in a hit list when a user enters a query. If you search for the word “meta”, you will find many web pages that give web authors tips on how to fool search engines by using the META tag.
