4 Weeks Giveaways: ... too much or not?

I guess it makes sense if it's part of a large train to give everyone enough time, but otherwise I'd agree it's way to much time.

You do you.

I make mine short. Only a certain number of people can win, so everyone else is just wasting points. It's a little different in groups. You need to make them long enough to get entries. Agreed with above, you make your own choices.

I can get a bit anxious with giveaways lasting more than a week so I tend to prefer doing ones that last just a few days, you can usually get a nice amount of entries in 48 hours anyway, although I guess trains are a valid exception since entries are naturally going to be much slower unless one brings attention to it frequently.

the very long ones... definitely only good for events(like a community train, more difficult puzzles on discussions, things like pagywosg, etc...)
but regular giveaways... its definitely way to long, only reason I could see keeping them that long is promoting social media/curator/etc...
I have found myself sometimes forgetting when I make super long GAs... just to get surprised by a "your giveaway has ended" popup.

around 1 week is more ideal imo, all active/semi active users would have a fair chance at entering that way, would say a minimum of a day so people actually get a chance to join/manage their points appropriately(assuming they aren't sitting at/near 400p all day like some of us).

I usually make short ones, because in most of time I have to wait days anyway until the key is used/marked as received, and I have many other things to do besides staying on SG XD, I do them short so I won't forget about them (I know, I'm old).
I bet I missed many giveaways for the games I wanted, so it's all about luck and good timing.

I don't see how a giveaway can last "too long". Unless participants or creators actively check in during the giveaway, biting their nails till it's finally done.
Personally I just let all my giveaways end on Thursdays 7PM every week, for many years now. And I completely forget about them in the time between. If they last 1 day or several weeks is irrelevant to me.

IMHO 24 hours is a good compromise too give enough people a chance to enter.

Ratio Groups - longer. I'm considering using a week as a standard for group giveaways because it helps the group stay active since there are more giveaways available at any one time. Anyone else think this is a worthwhile reason?

Public - extremely short, but a little longer for higher level ones. People here brought up a good point that long giveaways can mean lots of people wasting points as the probability decreases. Any level 0 giveaway, 1 hour is all you need.

4 weeks are too long for MY taste.
I prefer 3 days (and when i don't get then 5 entries in a group, then it is what it is. Better chances for the ones that entered the GA) or max. 1 week.

If someone want to promote/advertise something, then are longer GAs maybe smart.

Depends, but on average my sweet spot is 5 days, enough time for all active people to have a chance to join, and not too long for me to forget about it if something were to happen.

I don't like to make giveaways that last longer than one, maybe two weeks, unless they are for a scheduled event. Tbh I'm not fond of too lomg goveaways to enter, mostly because they take up space on the main page, and I prefer it to be cleaner :P
