I'd guess that it might be because the site is still pretty new and not everything has gotten indexed as quickly, or maybe it needs more time and backlinks to get ranked higher.
I wonder...
I do remember from way back, that there was a process to submit one's website to Google... I wonder if anyone actually even did that with Hive, or it was one small thing that got overlooked in the switchover, with no centralized team managing such usual minor tasks like that... 🤷♂️
It's possible.
Google didn't find this image, either. It's stored on steemitimages.com.
Hmmm....
