Free For All - Listing technique that
is used to build liking campaigns that offers little to no value to the
overall web experience and actually sometimes hurts web sites.
Free for all links are not typically categorized and
therefore usually are virtually worthless. Free for all links may hurt
your site as many poorly made sites use techniques such as free for all
listings and guest books to artificially attempt to build link popularity.
Most major search engines are already aware of such linking
techniques and consider free for all pages spam.
In addition signing up for such pages usually bombards
your inbox with spam.
