Hi there! In case you haven't figure it out yet, MadeWithGhost, is entirely free to use, browse, submit to, stare at for too long, and eat a snack with while browsing sites made with Ghost. We do not attempt to compete or even come close to competing with anything that the Ghost foundation has going on for revenue generation.
The site being free does not mean that operational costs magically become free, therefore, as you probably have already noticed, there a few advertisements around the site. These "ad-blocks" are affiliate links designed to stand out and clearly look different than everything else. If you click on of the ads it may, or may not, generate a small amount of revenue in the event that you signup for a company's offer. This comes at absolutely no cost to you whatsoever and may in fact provide you with a discount or credit for signing up via one of the links.
All of the products/services offered through affiliate links are products/services that I have used and personally recommend.
If you have any questions regarding any of the above information, don't hesitate to contact me completing the contact form here.
