The world suffers information saturation. What if you picked one niche and compiled all that information in one website to reduce the amount of time one spends on the search engines?
Take this example:
There are hundreds of people looking for cheap holiday log cabins. There are hundreds of individual log cabin websites on the internet. What if you created a database with all these log cabins along with their facilities and prices in one website? Now this is real value.
You can have affiliate marketing package with the owners of the cabins or you can charge the users of this website in exchange for access to such information.
