Is this because WP is now blocking outside adds on free accounts? WP recent advised users that ads may appear on free accounts. I saw that WP has a plugin just for Amazon posts, but any plugin requires a business account. In looking at the pay-to-play WP account details, it looks like one has to buy the second level account in order to “monetize your website”.
Part of the reason I recommend diversifying is because, as we talked about earlier, Amazon commission rates tend to be lower than they are from other affiliate income sources. I’ve seen this in my own affiliate marketing, where my commission rates and overall income from Amazon are not as high as they are for many of the products and services I promote on other platforms and from other companies.
And what about joining another company's affiliate program? It's all about extra revenue. Think about your customers' needs: What other products or services would interest your site visitors? Join those affiliate programs. Affiliate programs can increase your sales with no upfront cost to you. It just takes a little time to plan your strategy and select the partners that will have the greatest impact on your business.
