I have 3 PWYW products up on the DMs Guild, all dealing with elementals. The first one, called
Lesser Elementals, was added on February 24, 2016. I made the suggested price of $1.00. In the 3-ish weeks it has been there, it has been downloaded 204 times, with 14 people actually paying money for it (gross of $9.27, with one person even paying a penny). It has also gotten 3 ratings (5, 4, and 3 stars), but 0 reviews. The second one,
Elementals Expanded, was added on February 28, 2016. It has been downloaded 173 times, with 14 people paying money for it (gross of $12.65), with a suggested price of $1.00. It has received 0 reviews, and 1 rating (5 star). My newest one,
Elemental Myrmidons, was added back on March 7, 2016. In the 3 days it has been up, with a suggested price of $1.00, it has been downloaded 82 times, with 2 money transactions (gross $2.00). It hasn't received any reviews or ratings.
I do feel my products are worth more than what I have made from it, but I am actually surprised that anyone decided to pay money for these. I also have 3 more products in my Elemental line, and I plan to compile them into a single book and possibly make that an item with an actual price point. I am a little sad about the % of paid vs free (6.8% on the first, 8% on the second, and 2% on the third), and I would love to get any sort of review on them. Getting reviews on anything that isn't on the "Best Seller" part of the front page seems to be difficult.
I am sorta "doing this for exposure", but that seems like a difficult uphill battle, especially with how often new items get added to the DMsGuild. I noticed that the DriveThruRPG portion of the OBS sites isn't very active (the one where you can put OGL 5e products that aren't FR and now Ravenloft items), which makes me reluctant about making any non-DMsG items for 5e. It's the sole reason I put these elemental products on the dm guild instead.
Is my stuff great? I honestly don't know. There's one monster I am not entirely certain how well it is designed, but I don't know if it is or not as I have no feedback on any of it. It's abilities reflect the monster itself, but I don't know if what I made works. And I probably never will. I am just glad for those 20 paid downloads.
