which is the best way to promote our forum?

You can find related forums with same niche and actively post there. Add your forum link to your signature.

The only way is writing about it in places that interested people to that subject may read and also you should post new and unique contents to your forum that attracts people. The success of a forum relates to the number of members and users of it in my opinion.

comment on forums that are related to your niche...that way people will see your signature that is related to their interest and they might click on it...

Hi Raghu1231. You can:

1. Research data analysis. Conduct industry, business trade, online consumer market and keyword research and data analysis. Which exact match keywords with high monthly search volume are most likely used in Google by people searching for online communities with content in the form of info, tips, advice, techniques and strategies useful for their relevant needs and problems?

2. Identifying online network channels for effective promotions. Use each of those keywords in Google. Take note of the top page results that accept content contributions from viewers. These can be blog post discussions, forum threads and articles with comment boxes. Also take note of page results that most likely have a good volume of mailing list subscribers comprised of people with needs and problems relevant to your onforum content, products and services, whether they accept content contributions from viewers or otherwise. You have 2 lists of page URLs at this point for each of your target keywords: One with top ranking pages that accept content contributions from viewers, and another with top ranking pages that do or do not accept content contributions from viewers though have relevant mailing lists with substantial volume.

3. Online consumer market analysis. Go to those page result URLs and study the relevant needs and problems of your target market.

4. Onforum content, product and service development. Develop content, products and services for your forum which can quickly satisfy their relevant needs and conveniently solve their related problems.

5. Onforum content, product and service USP (Unique Selling Proposition) development. Integrate into your onforum content, products and services the benefits lacking from providers of relevant content, products and services. These added benefits can be more convenient onforum content navigation features, freebies bundled with your products, added services for your customers and diverse onforum content types that can match the different content viewing preferences of particular sub groups under your target market among others.

6. Traffic funneling. Go to the page result URLs that accept content contributions from viewers, as mentioned in number 2. Contribute beneficial content yet to be mentioned in those pages. Content can be in the form of articles, commentaries, videos, ebooks and PowerPoint slideshow presentations with info, advice, tips, strategies and techniques useful for satisfying the needs and solving the problems of page viewers. Your content contributions should be effective previews to more benefits offered by your onforum content, while your onforum content should be effective previews to more benefits offered by your products and services. Your objectives include: To funnel viewers from those pages to your onforum pages, and to have your content contributions and onforum pages syndicated by webmasters of contextually relevant websites for their target audience, which mainly consists of people with needs and problems relevant to your content contributions, onforum content, products and services.

7. Joint venturing. Go to the page result URLs that do not accept content contributions from viewers though have mailing lists with substantial volume, as mentioned in number 2. Negotiate mutually beneficial deals with the webmasters of those websites, such as guest content authoring for additional content on their websites in exchange for onpage and mailing list ads of your forum, onforum content, products and services.
Hope this helps...

Publish a blog that's on topic and SEO it. I've joined forums because I liked the blog it was affiliated with. As your blog traffic increases, so should the number of your forum subscribers. Include commenting in your blog to get people participating. In time, they may join your forum.

Try to get your forum listed with forum directories.

The first thing for said purpose is quality which is your main friend. Unique contents, a lot of work, and good design are the best ways to promote your forum. Promote with links in signature and post good messages, not spam. Make some exchanges, put the link in free to add directories.

Hope it will help
