Do any of you find you get better results posting adds on Wanted - Players at specific times of day or days of the week yields more players or higher quality players? If so what are they?

I don't know about specific times, but I think you'd be more likely to get responses on a weekday. Place tends to die down a bit on weekends from my experience. :)

Between the hours of about 11:30 PM and 7:30 AM GMT-5 won't help you any if you want instant traffic. Probably the equivalent of 1 PM or later where you want your players to come from (that is if you know where they're at, but chances are if you know where they're at, you would do better to PM specific individuals)

I posted one at noon EST on Friday and had 10 responses in four hours.  Part of it's the popularity of your game, but weekdays are always better.  Unless you specifically want people to be active on weekends, at least.

Yeah. Generally weekdays, and not in hours that are in the middle of the night EST.

But really as long as you are using a popular system (or at least not one that's super obscure and not easily obtainable) and have a solid concept, the timing doesn't matter much.

The impression I've gotten from all my games, though I admit that I haven't actually done a study on it, is that advertising for players Saturday tends to get you responses Sunday, while posting Sunday night gets you responses Monday.

Keep in mind that there is a wide spectrum of players here. Many players have jobs during the week, so they have more free time on the weekends. Some players are able to post from work, while others can't do so until they get home. A lot of players post from their smart phones. Other players can't post on the weekends due to family commitments.

And then there's time zones to consider. This board has players from all over the world. I've seen some from Australia, Japan, South Africa, Netherlands, and obviously the U.S., Canada and England.

So I don't think it's really about timing. As you commented on elsewhere, there are a lot of games represented here. I only play about 10% of them myself. Getting a response, especially a lot of responses, is more about appealing to a wide group of players. The more mainstream your game is, the greater the pool of players you'll have to draw from.

The next criterium would be a hook. If the title of your thread is clever or evocative, you're apt to get more players. Likewise, the title of your game and the setting are also important. Compare: 'Cowboys and Dinosaurs in the Old West' with 'Tyranosaur-bustin' Cowboys in the Wild, Wild West... On Mars!'

I'm not saying change the name of your game or the setting, just present it with panache! (Not that I do it, even though I should.)

The games I've posted, or bumped on Friday-Sunday all get buried by early weekday posts. The few games I've run seem to get many more hits if I post them Monday or Tuesday. I try not to bump or post initials on The weekend.
