Narrow down the topics by reflecting on profitability and other goals. In order to make money, you'll need to find a niche that other people haven't filled already, but is still popular enough to attract a significant number of visitors.

It’s dependent on traffic. Traffic goes up and down and you never know when it is going to do a major dip. Most advertisers pay based on the number of views their ad will get. This turns you into a traffic monster. You start to look for creative ways to get any kind of traffic, no matter if it’s good traffic or not. This can easily lead to your site becoming another junk site that you try to avoid.
Hi Sam! I love your site. We should definitely connect. I’m a school counselor and recently launched a site for parents to address pertinent teen topics. Like you, I struggle with the ultimate service I’d eventually offer on my site, but Ramsay’s idea is a great start. He’s absolutely right that people are looking for fresh content for their sites! Best of luck to you and I hope we can collaborate.
