Understanding the working mechanism of social algorithms is not a piece of cake. The algorithm for each social platform works differently. For instance, on Facebook, a core factor that affects the rankings of a post is its relevancy score, whereas on YouTube the total watch time of the video per session decides whether a video enters a ‘Recommended Video’ section or not.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
