Found something interesting (facebook viral)

I follow a few big sites like im sure you all do but i found something really strange with facebook shares and apost/

Apost is super viral all the time and looking at there URL each has different amount of shares but its the same content

apost(dot)com/en/blog/nobody-can-score-at-least-1015-in-this-insane-knowledge-quiz/5283/?un_id=1516129872374&vt=1516213778&sl=0 97.6K

Can someone shed some light on whats going on here???

This is just basic viral marketing, nothing special.

This is viral marketing the blogger has engaged the audience with a Quiz. You can do this as well if you want Social media traffic.

Yeah nothing strange here. They're just appending a number to the domain every time they repost it to keep FB algo from penalizing reach.

nothing strange ..

if you debug it says facebook hasn't scraped this url before. something strange in that URL not the post.

This is viral marketing.
