I succeeded in only a few online dates. (I'm away from a city and older, but still.) That said, , the most sensible-seeming advice is to express yourself and what's unique to you rather than trying to second guess what anyone else might want. Likewise good photos are fun and show something about you. It's good to avoid negatives in profiles -- list of don'ts and dislikes.

There's a lot of online advice dating profiles.
