There are several past posts here about the best use of filters. I advise you to search for them (keyword filter) to get more insight. Don't expect a POT to have professionally written, well thought out profile... That's what we do. :p And don't expect a POT SB who uses a term like FWB, NSA, or casual dating, to mean what WE think it means, with the possible exception of "platonic." Finally, stay away from using any direct reference to sex or sexual acts in your profile and your messages. That's a fast trip to ban town forever.
For me, I use the following as my standard or default search. Note you can save multiple searches for easy access later.
Radius: 10 miles
Age: 18-35
Body Type: Slim and Athletic
Smoking: Non-smoker
Tags: I exclude "Seeking Trans friendly" and "Seeking Transgender"
Sort order: Newest. And once I scan the newest profiles, I switch it to Recently Active
That's it. I generally only look at profiles that have been active in the last 3 days, preferably they are online now or in the last 8 hours. Longer offline times can be stale...
If I'm not seeing anything interesting I play with radius (increase to 25) or add body type Average, or add a keyword (wine, bikini, mentor, etc.).
Please experiment and let us know what works for you, as well as your general market location.
