Now I've done this a couple times, and it seems to work well each time. That's why I'm sharing it with everyone here Well, I'm also sharing it because you can't really saturate this lol
Now then, all you have to do is a lot of up front work and then coast. It's a difficult thing to do in the beginning, but it will pay off for years to come, guaranteed.
What will you be doing? You'll be setting up a review website that has detailed reviews of your own services or products ;) And of course you'll be linking to your own products or services because that's how you'll make money
I always use wordpress and a premium theme for this because I can get a great looking review theme and use it multiple times, even though the terms when buying the themes always say something along the lines of "You can only use this theme for one website blah blah blah!" but don't listen to them, you're fine and can set up 10 review sites using the same theme if you really want to This is also why I save every theme I've ever bought
So when you're picking the right review theme for what you need, you'll need to make sure it has a few features/plugins.
Features/Plugins you'll need:
Rating System: Most review themes will come with something like this coded into it or it will give you access to a paid plugin that will be installed. You'll need a rating system to show your own ratings of the service or product. The person reading this won't know you're giving yourself high rankings, they'll think you're giving a 100% honest review and they'll be more willing to purchase.
Responsive: Your theme must be responsive. This isn't really a feature or plugin, but it's important.
Yoast SEO: This plugin is one of the best for on page optimization. After you post your content it will evaluate it and let you know what needs to be edited or added in order to have the best performance.
And that's about all you need
Take your time writing up the reviews on your service or product because that will basically be your sales page, but in review form. Always leave a positive review because people won't buy if something is neutral or negative.
