If you’re planning on relying on SEO for traffic which most people do, it’s all about finding keywords where people would be interested in purchasing an affiliate product, and analyzing the competition of each of those keywords. Back when I was promoting Genesis themes, I saw hardly any articles about “Genesis eCommerce themes” (when I Googled it) which was a popular keyword. I got myself #1 for it. For SiteGround and StackPath, I saw opportunities to write articles on “settings” for each cache plugin (W3 Total Cache Settings, WP Fastest Cache Settings, WP Super Cache Settings, etc). After researching these keywords I was confident I could write better tutorials that the ones out there.
Have you considered bookkeeping? Crochet seems more like a hobby but you can still make money from it, I’d definitely consider looking at the type of crochet work that’s on Etsy to see if it’s something you can compete with. It sounds like you could be a great bookkeeper, I’d highly recommend checking out the free training above or upwork for freelance opportunities.
Like talking to people and helping walk them through problems? You can bring in extra income as a contract customer support superstar for companies all over the world. Due to the 24/7 nature of online businesses, companies are looking for people in different time zones to help deal with issues that their users are having. Better yet, if you have experience in service or retail you’ll be perfectly suited. Check out indeed or the other remote job boards I listed earlier to find opportunities.
Before promoting your site, you would want to make sure there is a good amount of content there. You need to write several product reviews with 2-3 in each category created. You might also need to make categories for news, articles, commentary and others about the topic. The more the content on your site, the better. The amazing thing about all this is that as you writing all this, the search engines automatically are getting notified, if you turned the notifications on, mentioned earlier.
Then once you’ve got your domain name and hosting sorted out, it’s time to pick a CMS, or Content Management System, that will let you update pages, build your blog and integrate with all the other services you need. It’s hard to go wrong with WordPress—the CMS powering close to a quarter of the internet. Keep in mind that eventually as you start growing traffic to your blog, you'll be wise to invest in a managed WordPress hosting plan from a company with great service like Kinsta, where all of the settings are custom-tailored and optimized to work particularly well with WordPress-powered websites.
