K Storm, it's not just you.
There may be traffic to the sales' page, but it doesn't translate into a lot of traffic to our pages.
Also my games published here have very little following here. On itch.io I suspect people mostly follow me for the free game assets - so there aren't people waiting for me to put something on sale.
For the past few sales, my bundles of my own games have not even appeared on the sales bundle page. I don't know why - but they're not there at all.
There again it's difficult for me to promote the itch.io sales on social media mainly because the sales coincide with American events like Halloween, Thanksgiving or seasons that match the Northern Hemisphere and are opposite to the Southern Hemisphere seasons where I live. So from my side I'm not driving traffic to my page either during sales events.
But I participate because on occasion, I sell a Clickteam tutorial during the sales and because I want to support Itch.io in whatever way I can.
