Search Engine Forums, SEO Forum

It is not really that important unless your target audience is in the forum too. But for backlinks, it is not that reliable.

Most of forums are giving Do-Follow links. And forum posting can drive good traffic on your site.

Well, I guess you can also increase your visibility with forum postings. The more forums you post to in an intelligent and contributing manner, especially related to your website's topic, the more visitors and reputation you draw directly. So a link can be twofold:

1) A backlink Goolge gives you credit for and

2) A direct engagement with people, hopefully your target group. Of course you can also learn new things on your subject and stay in the loop.

Forums are important to me. I use it to promote my signature of my site and to look who need SEO services

Forum posting is all about generating more quality and targeted web traffic to your website. There is definitely a right and wrong way to do it though.

Forum posting is a great way to build up the backlinks of your site. Most forums allow you to include a link to your site in the signature area. Each forum has its restriction regarding the number of links and word count limit in the signature.

Forums are essential because they are always fresh with those new contents from posts.

Read the forums rules and guidelines before posting for the first time.
Ignore spammers, respond to them personally and not through the board, or report them.
In order to be understood by most people, use correct spelling, grammar and avoid slang unless you know the word or phrase will be understood by other members.
