Problem with Google and also other big companies like Facebook is they are becoming delusional and trying to improve their algorithm etc., until it is completely broken or useless. They already reached the top and they always try to push it more (probably because innovation and improvement will push their stocks) but at this point, their decline already starts.
Google algorithm was much better in 2014 than it is now, imagine this shit.
I don't even blame Google for it. There are just SO many external circumstances like fake news, hate speech, stock market, guys who are using Google with a bad intention and so on. Just look at how Facebook and Google are getting roasted in the US. Always have to go to congress etc., basically getting humiliated from some old idiots, which got no clue what they are talking about, calling themselves "politicians".
All this stuff is slowly messing up Google and so on.
Especially in the context of "Fake News" there are some immense consequences on Google search. If you have noticed: Since Donald Trump was elected all this stuff with "Fake News" came up. Before 2016 no one gave a fuck about fake news and it was not actually a real term. Actually we can see all this weird stuff on Google happened since 2016, before the algo was way more predictable. You could make a nice website, great content and some decent backlinks and you would 100% start climbing the serps.
Not anymore.
Now it seems to me they try everything to prevent new websites to rank. They give a huge boost to high authority sites, which are already established. Thats why we see so many .edu, gofundme.com, Pinterest.com etc. websites starting to rank, even if the content is pure spam. Meanwhile new websites/domains are getting an algo penalty or being sandboxed for several months.
