You should increase the surface area of your <a> tags in the ads. Ideally they would cover the whole card and the egg, too. Also, consider adding a hover effect and a "pointer" cursor. I was trying to click your ads and I couldn't figure out how to!
Agreed that I was very confused in not seeing a pointer cursor on hovering _anywhere_ on the Ad card... any way this could have been made as a conscious decision to minimize the whole impression of the page being too invasive with its ads?
