How to increase visibility/effectivity of affiliate links?

[Apex]

How do you make the affiliate links stand out for users? On my website I publish articles with affiliate links to Amazon and I would like to know how I can increase visibility for visitors. Right now I use buttons with the text "Buy now!", but I would like to know what works best for you.

If it’s a buyers guide, a comparison table at the top of the article gets me the most clicks by far. I have an image link and text link for each product in the table, and these links get 60% - 90% of all click on every article.

For other articles, text links seem to do better for me than buttons or images.

I use comparison tables at the top of the article as well as product boxes and internal links within the body of text. I would imagine the best way to increase your CTR is to target a buyer keyword though. Something like best dog collars would get more click throughs than a keyword like why does my dog keep scratching its dog collar.
