Well, here are some ideas to get you going:
The first idea is to create a directory site. You may have to become a member of UAW to do this, but that’s worth it anyhow. (http://danmorrismarketing.com/uaw is my affiliate link to that). Once you become a member of UAW (which is an article spinning site that I love), you’ll get access to the free Directory in a Box software. Very nice stuff.
Another idea is to load up a WordPress site and use Yahoo! Pipes or another feed aggregator to direct content to it automatically. If you are unsure what Yahoo! Pipes is, please ask me on my http://freeweeklymastermind.com Facebook page – That’s where your questions get turned into videos, teleseminars and straight answers. I’d set up a YouTube account for your niche and redirect one of your domains there – to make it easy for others to find it. Perhaps do the same with Flickr, Facebook, and Twitter.
Set-up a Squidoo or HubPages site and redirect one of the links there – not to mention a quick Blogger.com and WordPress.com account. – Then make sure to use the url in a link to these sites. Once established, you can then use these sites to build links back to your niche sites.
And you can always try to make a few bucks using WhyPark.com
