What changed on Instagram, TikTok, YouTube and Meta this week
The platforms push out changes every week, and most of them don't matter to a business account. A few do. Every Thursday we read through all of it so you don't have to, and tell you what to do about the ones that count.
Three updates that change how you should post
YouTube Shorts algorithm now favors original videos over reposts
YouTube changed the Shorts algorithm to push original videos and reduce reach for re-uploaded or aggregator clips. Instagram made a similar change in April.
Facebook is testing limits on link posts for business Pages
Some Pages are seeing a cap on how many posts with outbound links they can publish. Meta has long reduced reach on link posts; this is a harder version of that.
Instagram lets you add tagged posts to your own profile grid
You can now pull a post someone tagged you in onto your profile grid, next to your own posts. Instagram also published an updated Reels creation guide.
