This sounds like a nightmare. Google will punish this site heavily for duplicate content. It typically doesn't like content aggregaters that add no novel content.
I already have a similar aggregator site which wasn't punished by Google. (I was surprised too)
~25% of traffic comes from organic search, and its average position for the 2 most relevant keywords are 1.3 & 6.
I think (one possible) reason is that the site doesn't copy the original content, just links to it.
IMHO an aggregator site
can be helpful (and provide value) for users if it's not just simply copying for "SEO hacking".
Maybe the google AI thinks similar as me. ( Useful to user = better ranking )
This is why I thought I could try now something bigger.
Are you planning on making a news site eventually with your own content?
I'm not a writer
I'm a coder who is too lazy to hunt for fresh crypto news daily.
So I decided to make some automatized stuff what makes my life easier.
And why not put it online? Maybe it could be helpful for other people on the other side of the world too.
