Hey, I see a lot of people not making money by this mark (I was one of them). If you're at the 6 month mark and aren't getting traffic and haven't made a single sale you need to switch up your strategy.
You need to be writing review posts or best of lists - all the time, I gurantee if you write reviews and best of posts for the next 3 to 6 months you will start making sales regurarly. At least half your post should be those two types of content.
Just to be clear you don't need to change niches or abandon your website at the 6 month mark but you'll need to change up your keyword and content strategy.
When you find a winning content strategy stick with it.
