Facebook Newsfeed Optimierung: Gefällt mir

2.500 Aufrufe

Veröffentlicht am

Internet-Nutzer verbringen bis zu 25% ihrer Online-Zeit auf Facebook und davon ein Drittel mit dem Facebook Newsfeed. Doch nur 16% der Facebook Posts einer Unternehmensseite erreichen überhaupt die Fans. Schuld ist der EdgeRank-Algorithmus, der die Reichweite eines Postings aufgrund seiner sozialen Relevanz und Aktualität steuert. Diese Session beantwortet die Fragen „Wie funktioniert der EdgeRank-Algorithmus und Newsfeed-Optimierung?“ und „Was steckt hinter dem Last Actor Prinzip und dem Story Bumbing?“
