I have recently started a new web project ( https://industrydecarbonization.com/ https://industrydecarbonization.com/ ) where I am relatively closely following how it does on search engines, and I can't say that I share those experiences. It took a few weeks until google noticed that it's a page with relevant content, but that's kinda expected. But once it did I feel Google is indexing my pages extremely fast, so fast that I have been wondering how they're actually doing this. I post new content on various social media sites, and my best guess is that google gets some of them as direct feeds that they check for interesting links. Google does not support indexnow, and as far as I know also no similar feature (except manually via the search console), so I'm not in any way directly submitting my content to Google.
