Some education niche, that was running nicely for many years.. #1 was some unisersity for most case. my site #2-3. I was wondering "who is that new kid o the block".. was sniffing around today.. some "startup" with 1,3 million € venture capital. !!! Linkprofile.. from 300 RD were 200 RDs full of authority high quality (on real sites - ya know, the sites most of you will never achive or have moeny to spend for ) blog posts. a mix of manual guest posting and bought posts. result? even if some UN-related keywords are on their page sprinkled , they outrank 2 spots above me just cause of their high authority. dam. sucks.. all that stuff that's comming up for the last 2 years now on the european market - there wont be much space left to earn anything on a broader scale UNLESS you scale shit up to notch..
