It’s been a busy month.

Adam Mosseri has been talking. TikTok’s algorithm has quietly shifted again. And nearly every major platform shipped something this month that changes how content actually gets seen.

Here’s the July 2026 social media algorithm updates that are actually worth your attention, and what to do about them.

1. Adam Mosseri confirms what actually drives Instagram reach now

Adam Mosseri (Head of Instagram) has been clear about this all year, and it’s still the most important thing to understand going into July.

The ranking signals that matter, in order:

Watch time
Sends per reach (DM shares)
Likes per reach

A DM share is now worth roughly 15 likes in Instagram’s distribution model. A save is worth around 10. Likes and follower count barely move the needle anymore.

If your content strategy is still built around getting likes, you’re optimising for the wrong thing.

2. “Your Algorithm” just expanded to the main feed

Instagram first tested this for Reels, then brought it to Explore. In July, it expanded to the main feed too.

It lets users see the interests Instagram has assigned them, then choose to see more or less of specific topics. Mosseri has said he wants it to feel less like a hidden setting and more like something central to the app.

For brands, this reinforces one thing: content that clearly fits a niche or recurring theme will keep finding the right audience. Content that tries to be everything to everyone won’t.

3. Instagram is cracking down on duplicate trial Reels

This one matters if you’ve been using trial Reels to test content before posting to your main feed.

Instagram now scans for duplicate and near-duplicate content, including slightly edited reposts, and reduces reach accordingly. There’s also a new daily limit of five trial Reels, with accounts going over that risking a spam flag.

The move to make: stop posting the same trial Reel with minor tweaks over and over.

Use trials to test genuinely different hooks, edits or angles, not the same video five different ways.

4. Carousels now support a caption on every slide

This is the update everyone’s been asking for.

As of late June, Instagram lets you write an individual caption for each photo or video in a carousel, instead of one caption for the whole post.

As people swipe, the caption updates to match the slide they’re on. It’s live for basically everyone now.

Why it matters: Instagram’s algorithm rewards dwell time and swipes. Slide-by-slide captions give people a reason to actually read as they go, rather than swiping past static images.

Tutorials, product breakdowns and step-by-step content are the obvious wins here.

5. You can now reorder your grid (and your carousels) without reposting

Instagram quietly rolled out grid reordering in June. Long-press any post on your profile, select “reorder grid,” and drag it wherever you want. Likes and comments stay attached, and pinned posts and Reels stay fixed at the top.

Carousels got the same treatment back in March, letting you reorder individual slides after a post is already live.

This means you no longer need to delete and repost just to clean up your feed or fix the order of a carousel. Small update, genuinely useful.

6. What TikTok actually rewards right now

TikTok’s algorithm has moved again this year, and the shift is worth understanding if you’re posting there regularly:

New videos go to a small test audience of your existing followers first. Strong performance there is what unlocks wider reach.
Completion rate is the strongest ranking signal, and the bar has moved. You now need around 70% completion to have a real shot at going viral, up from roughly 50% in 2024.
Longer videos (60 to 180 seconds) are consistently outperforming quick 15-second clips.
Original audio is being rewarded more heavily again. Trending sounds still work, but original audio gets a boost.

The shift here is away from chasing trends and toward making sure your existing audience actually watches to the end. That’s what earns you the next round of reach.

7. TikTok banned AI voices in shopping livestreams

TikTok updated its Live rules this month to ban non-real-time verbal interactions in shopping livestreams, including AI-generated voices, pre-recorded audio and radio-style scripts.

If you run or plan to run TikTok Shop lives, hosts now need to communicate in real time, verbally or via sign language. Pre-recorded, AI-voiced streams risk being flagged as non-compliant.

8. Threads and LinkedIn are worth a second look

A couple of smaller updates worth knowing:

Threads hit 500 million monthly users this month and used the moment to move Communities out of beta, plus roll out its own version of “Your Algo”, letting people dial specific topics up or down.
LinkedIn added GIF support in comments and is testing collaborative posts, where multiple people or Pages can co-author a single post. Useful for product launches or team announcements that benefit from more than one network amplifying it.

The takeaway - Social media algorithm updates

July made one thing clear: the platforms rewarding reach in 2026 are the ones built around genuine engagement, not vanity metrics.

Instagram: watch time, saves and DM shares over likes
TikTok: completion rate and longer, original content over trend-chasing
Both: originality is now a ranking factor, not just a nice-to-have

None of this means starting from scratch. It means being intentional about what you’re actually optimising for.
