At this point, you're through with the technical setup of your website. So, you already have a niche in mind, and now you've got a website that's connected to Google Analytics and Google Search Console, which means you can track your traffic and appear in organic searches. Your visibility rating just went up dramatically, but don't worry, no one can find you yet.
The good news is, domain names are very cheap. A domain name usually costs around $14/year and when you’re a member of Wealthy Affiliate, you’ll get your web hosting for free so the only “added cost” is your domain name.

The affiliate network then also serves as a database of lots of products, out of which the affiliate marketer can choose which to promote.
You should try finding niches that you are interested in and in which you don’t have massive competition. The less competition, the better. You should focus on that niche almost exclusively. Find products that can best encapsulate your audience and optimize your campaigns the best you can. After you are dominant in your niche, you can try spreading out to other niches, but don’t try spreading too fast as it might be a difficult task.
