[HELP] Facebook Link Posts Question

I have couple of fb pages and when ever I share link from my website the links get 1/4 of the clicks as opposed to sharing a link from lets say littlethings.com. Same goes for the reach.

Here is some examples




The links are posted 2 hours in between.

What could be the reason for this.

The way the fb algo works?

FB wants you to boost your posts so they make $$$.
