I launched FeedRiv.com on Product Hunt today. This was my first time to launch on Product Hunt so I wasn't sure what to expect. I didn't put a lot of effort into promoting the launch so I wasn't sure what to expect.
After a few hours, I had 23 upvotes which was a lot more than I anticipated (I was expecting 2 or 3 upvotes). However, the traffic to my website did not significantly increase. Right now I'm sitting at 30 votes with still a bit of the day to go.
I see why people enjoy doing product launches on PH (you get a lot of congratulatory comments and excitement from seeing your votes go up) but I'm not sure how much value it provides in the long run.
I do think it increases your visibility to others, so from that standpoint, I think it has been successful. Going forward, my plan is to continue to post on Product Hunt, but I won't be putting a lot of effort into the launches.
