ShortPixel is a very useful plugin that optimizes images to reduce the load and improve website loading time.
It compresses all images on a website with one click and the best part is that, the images hardly lose any of their original quality while reducing size. This plugin also works great for serving images from CDN. All of this combined can do wonders for ranking better on search engines.
ShortPixel has a generous affiliate program that offers 30% commission for all sales you refer to them, including recurring ones. Their tracking cookie lasts for 30 days and your commissions are paid via PayPal.
However, if you’ve earned more than $500, then you can request a payout via different payment methods as well.
