Facebook did not just give every &quot;fan&quot; page an equal-sized traffic haircut. They started limiting page content in accordance with how much organic (non-paid) engagement it gets.<p>So for example Facebook pages like &quot;Humans of New York&quot; or &quot;I Fucking Love Science&quot; or &quot;Amy Poehler&#x27;s Smart Girls&quot; still get popped into a lot of timelines despite (to my knowledge) not paying at all for boosting. Why? Because a lot of people love that content.<p>But if some other Facebook page saw a huge drop-off that stayed dropped off, then maybe that content is just not as interesting as other pages (like the ones above for example).<p>And in fact this is why Facebook made changes to page content visibility in the first place. Most pages posted boring obvious ads instead of interesting content.<p>Pages can still pay for higher visibility, but those are ads. Just like people can pay to &quot;get into the New York Times&quot;--via ads, not articles. And just like the NY Times, there is only a fixed amount of ad inventory at Facebook. Even when pages are paying, Facebook limits their audience, in order to keep the audience happy. No one wants to see a newsfeed full of 100% ads. Or even 50% ads. Or 25%.
