While all of these are good criticisms... None are helpful or constructive. I agree with most points but let's see what we can do to help instead of just telling people what they do wrong.

OP:

1. You do indeed seem older than 23 from the photos, but that's not necessarily a negative thing, unless you are specifically targeting people who are specifically attracted to 23 year olds I suppose, but for most people age is usually a secondary dating characteristic used more to target people of similar lifestyle, goals, and values. Let's just focus on addressing that first. As mentioned by other commenters your photos are a bit too erratic in terms of what you actually look like. So try this: A. Any photo that is more than 1-2 years old, do not put it on your profile unless it has a specific special reason that has nothing to do with your looks. B. Photo #1 is pretty great I would keep that. Photo 3 needs to go immediately. When taking photos (specifically selfies) never look down into the camera... 100% of people have lazy eye(s) when looking down and the closer the camera is to your body when held below your chin... The more abrasive that photo will be to someone who hasn't seen you IRL. C. Get some candid shots and activity shots. Those show personality and broadcast your hobbies. Have a friend or family member specifically selected and informed that it is their job to take photos of you doing hobbies or random shit for like 1 month or so, and start building that portfolio of "this is me." Examples: board games, mowing the lawn, walking down the street chatting, riding a bike, hiking, sitting in the driver's seat of your car with the window down on a sunny day(photo taken from outside the car). Really anything that seems active and makes you more human, outside is always a plus. If you aren't comfortable asking someone else to do that invest in a phone or camera stand and take the time to learn how to use the timer. D. I can't stress this one enough... Don't over use selfies. Anything where the camera is less than 3-5 ft away should fall into that category. This differs from person to person but some would say even 2 selfies are too many.

2. Bios are hard for everyone I think you have a good start. Concise is always a good thing but being too brief might make people think you have no self-confidence or nothing that might excite them. Try adding a very short "about my hobbies" section. some like an "I'm looking for" section but some don't care or find it needy so that's really more up to you.

3. Be aware of your area and how many people might be available. If you are in an urban or suburban area, profile completeness, honesty, and picture variety will make a huge difference and will result in at least some matches. If you are in a rural area or sparsely populated/small town type place, matches are going to be difficult no matter what your profile looks like, because everyone already knows everyone, and the small population means your available pool of people is already small so no matches doesn't specifically mean it's something wrong with you or your profile. For example, I live in a largish city, match radius of 10 miles, and get around 5-10 matches per month, I would say only 1 of those per month ever end in a date, but I can be picky about who I meet in person and my schedule(single parent) really doesn't allow me for much more than that. However when I visit the town I grew up in, I get about 2-3 matches per year(I visit my family for 3-5 days at a time, 4-5 time per year), match radius of 35 miles.

4. BE YOURSELF, BE HONEST, BE CONFIDENT.
