playing other games and sharing feedback it's a good think to help other and show them what they need to do but those are the Developers and my target audience should be the Gamers not developers.
Well, this is primarily a developer's website. To reach a larger gamer audience you'll want to be posting elsewhere too, and having your games available on at least one of the big stores (google play, steam, etc). There is a population of non-developers here, it just isn't that big of a group. And a lot of them are really coming because they are enthusiasts, either of indie games in general, or of a specific niche within the indie sector. (People who come here specifically for visual novels are unlikely to be interested in your WWII shooter)
Already making devlogs and updating my games.
I know, but the one devlog I looked at was really just an advertisement. Normally you would just write about the update, what was added, things that were fixed, and your general thoughts. Some people get really into this and gain followers through writing about the dev process... I don't particularly like doing this but hey, it works for others.
i have no experience in editing itch pages.
There's a very simple built-in editor, just view one of your pages and click on "edit theme". You can change the fonts, backgrounds, add in=line images... a little work here goes a long way toward getting people interested in your work
