@gvidas_sulskis Overall, I would say depends on your personal launch target and goals.
On one hand, you may get traffic because people can specially come to PH on April 1 to check out what fun stuff is going on, and they may also check out your product.
But on the other hand, its silly that your product ranking will go down a few spots because the joke products are funny and engaging, and almost always end up in top spots.
Check out PH time travel tool to see historic April 1 launches and trends.
