A great way to market niche sites is through Yahoo Groups. Yahoo defines Groups as:

It’s where people with a shared interest meet, get to know each other, and stay informed. Your group gives you instant access to:

• Shared message archives
• Photos and photo albums
• Group event calendars
• Member polls and shared links

Best of all, Yahoo Groups are free.  So how can Yahoo Groups be beneficial for your websites? Two ways: Traffic and Links.

Most Yahoo Groups will have a place for members to add their links. Adding your link to the Groups directory is free. It may not drive a lot of traffic, but it will give you an important relevant backlink to your site.

You can drive traffic to your website by posting messages in the Yahoo Group. Every time you post a message it will send out an email to all the members in the group. If you have an attractive sales pitch in the email, people will click your link and visit your website. Some Yahoo Groups have thousands of members, so you can imagine how much traffic a quality email can drive.

I’ve used this method to promote proxies sites in the past. I don’t own proxies anymore, but at one time I did, and was making a couple bucks a day with them. What I did was joined the top 10 biggest proxy Yahoo Groups and then submitted my link to them all and posted daily messages on the message board. People in these groups wanted access to working proxies, so by constructing an email targeted to them and their needs (fast, anonymous proxies), I was able to drive traffic to my site daily. If the group is big enough, you can post messages several times a day.

Yahoo Groups can be used for all types of sites. Automotive, financial, blogs, forums and more. Be creative and you will benefit from them.
