1) Share it on as many platforms as possible.
You have an account on another webcomic-publishing platform? Good! Post a link to your comic there. You have a group chat app? Great! Get a little shameless and let your acquaintances know about your comic! You have an Insta, Twitter, Facebook, or any other kind of social media accounts? Advertise right away!
Ooor, you can make a post here in the forums...
2) Make your ad as intriguing as possible.
24 hours. That's the amount of time Laila has to escape the tower, before he comes for her...
Or a less cheesy one:
Just some random comics about random occurences.
Make it short and simple; you can elaborate it further if you want, but I like to place a one-liner before the elaboration and keep the whole thing maybe under 50-80 words.
3) Link it!
You know what I hate? When people don't give me a direct link to the website their talking about. Especially if there are several other comics in Tapas that have similar titles to your comic, it's just confusing.
And make sure to try the link for yourself to make sure it's working!
Good luck
