I've briefly mentioned this before but making friends on Wattpad is not only great for your social life but will also benefit you writing and books. They can give you advice on how to write and will also read your books because friends do that for each other.

If one of your friends on Wattpad has a book with a significant amount of reads, maybe ask them to give them a shout out because this will give you more attention and more readers will be attracted to your book. Don't force anyone to give you a shout out but maybe suggest it causally if you are extremely good friends with them.

This isn't guaranteed to get you more reads but it could make a few people click on your profile and check out your works.
