Hello. I found something intresting. When searching "Flat Earth Society" on DuckDuckGo we come as 3 result. Above us is other FE society and wiki page.
On Google we come at 37 place for now. I belive we were higher up before, as i didn't have to search it for so long?
Same for me in DuckDuckGo.
In google it comes up #15 for me.
'Search' is a complicated bit of business. I've never used DuckDuckGo before, so they haven't cookied me, know my search habits, etc. Whereas Google knows ALL of that stuff. So for me, it served up this site probably based upon all of the 'habits' they have logged for me. For some reason, for you, their engine served it up further down. Location is also a factor as well. No conspiracy, it's literally just how they ultimately make money - Off of your habits, traits, etc.
Other FE society came at 2 place, above wiki. Why does Google promote them and supress us?
Probably because their wiki is updated more frequently and their twitter presence is more timely/relevant and probably 100 other secret sauce things built into their algorithms. There's a whole MASSIVE multi-billion dollar industry around making sites show up more prominently in search engines - Look up
SEO and go down that rabbit hole for a while, then you'll understand.
Is it beacuse FE's here post real scientific stuff (I am thinking about sandokhan) which is threat to establishment?
No. See above and again, study up on SEO. It's a whole science with a lot of voodoo unto itself.
