Very good discussion guys and the perfect place for it...Forum Marketing Traffic!
Yes, the forum signature is vitally important in the way that it is crafted.
Just as important also is the content provided leading up to it.
Just as a salespage in a salesletter online or offline must immediately grab attention from the headline
and guide the reader through the process building value, agitating the problem, providing the solution,
presenting benefits of the product being offered, creating scarcity, building urgency, using fear of loss
and desire for gain all while focusing on the consummation of the order,
the forum post from the title of the thread (I like to call it a "threadline" which is a mix between thread title and headline)
to the closing leads up to the link as a system designed to accomplish the mission of getting the clickthrough.
The more anticipation and alluding to value waiting on the other side of the offer,
the more will take you up on that offer.
One vital aspect of forum marketing signatures whether using well researched keywords in your anchor text or not...
is the positioning.
For instance,
here is a short list of forums with page rank in Google with a value over at least 3 that DO alllow *dofollow* comment links!
This means, as long as you are adding value which is your "give" part of the relationship,
by ALL means, make full use of your classified ad for selling yourself to the members of the forum with a
nice strong call to action such as...
