Although posting on forums can be a great way to send some free traffic wherever you want it, you have to do it right. Otherwise, you won't get much worthwhile traffic at all.I've mentioned before that you should only post an advertisement in signature of your forum postings. Don't make message an advertisement.
But if your ad is in your signature, then you need to make sure people *see* your signature. This is obvious, but many people make it difficult to see their signature.
Typically, when you respond to a post by someone else on a forum, original message is, by default, included with your response. Often, people will type their response and leave original message below their response.
Here's an example of what I mean.
----- Here's a response to some message that someone else posted.
And here's some more of my response.
> Here's original message > from person who I'm responding > to. -----
Here's why this is important. Your signature goes all way at bottom of message. This means that it will be below original message that's included below your response.
How many people that read your response will continue to read original message as well? Most probably won't. This means they'll never get to bottom of message where your signature is. And if that's beyond bottom of screen, then your signature may as well not be there at all.
So I recommend deleting original message from your responses. If you want to respond directly to something that someone else posted, then just include part you're responding to *in body* of your message. This way, your response will appear under original message.
You always want your signature to appear immediately after *your* message.
Moving on. I've also mentioned that you shouldn't advertise off-topic products in your signature. This is especially true if you're posting on forums related to internet marketing.
And here's why.
Let's say you post a message on a forum about how to improve your search engine rankings. But in your signature, you post an ad for herbal health supplements.
