Be Trustworthy & Helpful
Readers are savvy. They know an affiliate link when they see one. If you break their trust by promoting a product you don’t believe in or take advantage of their visit with too many ads, they will leave and never come back.
It is your repeat visitors that will drive traffic. They are the ones who will give you link-backs, spread the word, and recommend your site as the go-to place for valuable content. You need to build a relationship based on genuine content.
If your visitors don’t think you’re being honest, they won’t read anything else you have to say.
Think of affiliate ads as additional resources that complement your content. Give value to your content by making it helpful, useful, and informative.
Don’t just put up a list of your links, books or whatever, hoping people will click on the affiliate link, purchase the offer (just because you listed them), so you can cash in on a sale. Take some time to write a detailed review or better yet, buy, use or subscribe to the product or offer and then use affiliate ads/links to point them in the right direction.
If you’ve actually tried the product or service and can attest to it’s effectiveness, then by all means promote them. That’s what affiliate ads are for.
For example, if you write a great review recommending a book or purchase/subscribe to a product and readers buy the book or subscribe to the product/service because of it, you should get something for that.
But just throwing out links to products and services with no rhyme or reason will result in a quick exit by visitors.
