This is what I've been told in the past from gentlemen:
They appreciate ads that don't have emojis in the title, it makes your title look more professional if you avoid those addicting emojis, I know they're cute lol.
The main things gents look for in an ad are travel dates & availability times, rates &/or specials, & a brief & unique bio about yourself. (measurements, eye color, hair color, fun facts)
I've also learned this recently, your ad will have more of a chance of getting viewed if you add a new selfie in it. I've been told several times, the gents love professional photo shoots, but nothing is more accurate than a down to earth & sexy selfie. Make sure you add in the title you put a selfie in there.
I know I'm not a client but I hope these tips were somewhat helpful
