@mikeh1995,
Online dating, much like the old newspaper personal ads, is dominated by men seeking women. Women have a lot of choices for someone to meet; men generally don't. It is a numbers game, and it favors het women as they tend to be rarer on these sites.
Do what any advertiser (for that's what you are, even if you don't notice that) does when one method is not working - try other methods. Go to places that you like and engage in activities that you like. E. g. if you are a churchgoer, go. If you enjoy hiking, go hiking, and join a club that does that. Like to read? Join a book club.
You might or might not meet single women within your age range at any of these places. But you WILL meet people who know and/or are related to single women within your preferred age range. Network! And see what happens.
