Hello folks,

Last week i released a game (https://hayo.itch.io/fishheadblueprint). I built the project page about 2 years ago (set to "under development") and posted updates using devlogs. When it was done I set the project to "released" and posted a devlog and ticked "major update or launch".
A week later the game is not showing up on any page, not even under  "fresh games". Now it is doing okayish on Steam but it does not get noticed at all here.  What am I doing wrong?

Your game is indexed and showing up in a title search just fine. If it doesn't seem easy to find otherwise, it may be due to poor choice of tags. You really should pick what other people use, because those are also likely to be sought out. One of your tags is unique to your game, and another is niche to say the least.

Also, from a quick view, your devlogs mostly just embed a video, with at best a few words on the side; those aren't going to get indexed well at all, either in Itch or in search engines. And search engines can be a big source of referrals.

Thanks, I will look into that. But should it not automatically be added to  "fresh games"? 

And as devlogs are concerned, I posted devlogs for this game for two years during production. Now it is done, what else can I do but post the trailer?

I'm not sure how games end up under the "fresh" header. It may well be that the game did appear there, but only briefly. And you could try writing proper blog posts, since that's what search engines index well, or for that matter at all.

Thanks again. It seems to me it is unwise to publish the project page before the game is done.
