On the other hand: the main reason of bankruptcy for small businesses is bad financial management. Simply said: to forget to make invoices, not checking the payments and not following bad payers. 1 out of 3 is going bankrupt for this reason alone. I had to learn it myself. I spend at least 10% of my time with financial stuff. I don’t love it but the bills get payed ;-)
These add review stars to snippets and increase click-through rates. I have tested many rich snippet plugins over the years and my favorite (and what I use now) is the WP Review Pro Plugin by MyThemeShop (view the demo). It’s fast, looks great (here’s a page I use it on), comes with 16 pre-styled designs, supports user reviews, and is well-supported by the developers at MyThemeShop. I was previously using WP Rich Snippets but the developer abandoned the plugin and hasn’t updated it for 2 years, and All In One Schema lacks customization options.
Hands down I’d say the best thing you can do is research 1 primary keyword, craft an enticing article title that includes your keyword (though it doesn’t have to be an exact match), spend time writing your search engine snippets (SEO titles/meta descriptions), and by far the most important is making your content as VALUABLE as possible through videos, nice graphics, table of contents, bold/colors/styling, etc. Small things like keyword density barely matter.
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.
Once you have the affiliate links you need, it is time to present them to your audience. As you start using affiliate marketing to talk about products, you need to be aware of how your audience perceives you. If your website appears to be only after their money through an overwhelming amount of affiliate links, then they are more likely to simply leave your site.
