A few years ago I started a website/forum called "Ride The Red" which served as an online community for Honda ATV owners. It was a great learning experience and I am kicking myself in the rear everday for selling that site.
Here are some tips:
- If you can afford a VB license then I highly recommend doing so because of its nice functionality. If not then alternatives like PHPBB will most certainly do the job as well.
- Until members and traffic are at a steady growth keep the number of categories to a minimum. Having too many categories at launch will make the forum seem bare.
- For each category you create use descriptive keywords not only for the title but the description as well. This will be useful for both visitors and the SE's.
- Keep the ads and banners to a minimum until members and traffic start to grow. Having too much on launch may make the members feel that you are only trying to make money.
- Create a newsletter system to help keep the members coming back. I even went as far as sending "We have been missing you..." emails to members with low visits and post counts to try and get them interested again.
- Start new threads daily on your own that are based on interesting topics. This will help encourage members to post.
- To get the ball rolling initially hire a forum posters to post on good related topics.
- Put a descriptive link in your sigs at other forums.
- Have a "Member of the month" feature. This helps others learn about the others in the community.
- Once established do product reviews and sell advertising space. I was able to get approx. $800+ worth of free parts for my atv just for contacting vendors and asking for a free product to do a review on.
- Choose additional moderators wisely. I selected a few members who really stood out and were experienced to be my mods. Two were actually certified Honda mechanics which found their way to my site
- STICKERS: For some reason stickers were a BIG hit! I gave each new member a sticket upon signup and then sold additional stickers cheap just to cover the cost.
- SHIRTS: T-shirts were also a BIG hit. Just something to help spead the word or url in this case.
I will add anything additional I can think of.
