Great find, Linda! Very good resource material!
You CAN really attract a solid audience with niche mini-sites.
- Discover what everyone is looking for (Google Trends is great for up-to-the-minute stuff)
- Get some good PLR articles on the subject and re-write
- Add a few RSS feeds throughout the site that deal with your subject to keep the information on the pages fresh (no javascript, since SE's don't see it. Use PHP)
- Create a store using PopShops with goods that your visitors would like
- Mix in some Adsense (not on the store pages. Better to get the merchandise commission!)
- Shake well and there ya go!
My recipe for a great mini-site! Now move along, rinse and repeat!
