So this is something I used to do when trying to get more followers but I think it can help get readers as well.

When you make an account on Wattpad, the first person you follow is the Official Wattpad account (I think this is still the case). So if you ,as a writer, are looking for new readers- look at the newest followers of the Wattpad account.

People that have just made an account probably will be new to Wattpad and will have an open mind about books. If you follow them first and leave them a nice message greeting them to Wattpad, they will most probably check out your account and your books.

Unlike older readers on Wattpad, if your book is the first book they read on Wattpad they will be more likely to comment and vote because they're excited- this may be a whole new reading experience to them.

Only con of following new accounts to Wattpad is that sometimes they will just ignore you because they are too busy either sorting out their account or they have already found some books to read.
