If your reach suddenly dropped, or suddenly jumped, this year, an algorithm change is a likely reason. This guide lists the social media algorithm changes of 2026 that the platforms themselves announced or confirmed, as of September 2026, with the date and source for each and a plain explanation of what to do about it. It covers Instagram, TikTok, YouTube, LinkedIn, X and Facebook.

Key takeaways

Instagram, Facebook and X all took action in 2026 against accounts that mainly repost other people's content, through lost recommendations or lower payouts.
Viewers can now steer their own recommendations with tools such as Instagram's Your Algorithm, Threads' Your Algo and YouTube's prompt-based custom feeds.
LinkedIn rebuilt its feed in March 2026 with large language models that match posts to professional interests, and said engagement bait would be downranked.
TikTok's US joint venture, formed in January 2026, said it would retrain the US recommendation algorithm on US user data.
X published its Grok-based ranking code in January 2026 and in August launched a tool showing whether labels are limiting your account's visibility.
Across platforms, the safest response is the same: original content, clear topics, honest AI labels and decisions based on engagement rates.

The biggest changes fall into four themes: originality, viewer control, AI-powered relevance and AI transparency. Here is the summary.

Facebook	New original content guidelines	12 March 2026	Add real commentary or make your own footage

What changed in the Instagram algorithm in 2026?

Instagram made originality a condition for reaching new people and handed viewers more control over what they see.

Originality rules extended. On 30 April 2026, Instagram said accounts that regularly repost content they didn't create would no longer be recommended, extending a rule that already applied to Reels to photos and carousels. Watermarks, speed changes and screenshots of other people's posts don't count as original; your own humour, commentary, text and edits do.
Your Algorithm everywhere. Instagram's topic controls launched on Reels in December 2025, reached Explore in April and went live across Feed, Reels and Explore on 10 June 2026.
Engagement rates over reach. In May 2026, Adam Mosseri told creators to focus on engagement rates, explaining that likes matter more with followers and sends matter more for reaching non-followers.
Four ranking principles. In September 2026, Mosseri listed originality, recency, testing smaller creators' posts with non-followers and a larger ranking model as the principles behind ranking.
AI profile labels. From 31 August 2026, Instagram limits the reach of profiles featuring an AI-generated person that don't use its "AI generated profile" label.

What to do about it: Make sure most of what you post is your own. Name your topic clearly in the first line of captions and on screen so people who ask for "more fitness" or "more small business tips" get you. Test new ideas with trial Reels. Our full guide on how to grow on Instagram goes deeper.

What changed in the TikTok algorithm in 2026?

TikTok's biggest changes were structural in the US, plus more creator control over search and more viewer control over AI content.

US algorithm retraining. The new TikTok USDS Joint Venture, announced on 22 January 2026, said it would retrain, test and update the content recommendation algorithm on US user data. This applies to US users.
Local Feed. On 11 February 2026, TikTok launched an opt-in Local Feed in the US that shows nearby events, food, shopping and services, after earlier availability in some European markets.
Keyword management. From May 2026, TikTok shows creators the keywords it has attached to their videos and lets them suggest or block terms, with TikTok keeping final say.
AI content controls and spam detection. TikTok has been testing a Manage Topics setting that lets viewers see more or less AI-generated content, and in July 2026 said it was testing better detection of AI-generated spam accounts on topics like politics, finance and health.
Richer comments. On 3 September 2026, TikTok added voice comments, comment polls and photo carousel replies.

What to do about it: Check the keywords on your top posts and remove any that misdescribe them. If you are a local business in a market where the Local Feed is available, tag your location and film recognisable local places. If much of your audience is in the US, compare your US and non-US analytics month by month. See how to grow on TikTok for the full playbook.

What changed in the YouTube algorithm in 2026?

YouTube is pushing back on low-quality AI content while giving viewers more ways to shape their recommendations and creators more ways to test.

Fighting "AI slop". In his 2026 letter on 21 January, CEO Neal Mohan said YouTube would use its existing spam and clickbait systems to reduce low-quality, repetitive AI content. He also said Shorts average 200 billion daily views.
Custom feeds and Ask YouTube. At Made on YouTube on 23 September 2026, YouTube announced homepage feeds that viewers create with written prompts, an expanded Ask YouTube for recommendations, and A/B testing of up to three versions of a video in YouTube Studio.
Shorts series and TV. YouTube began rolling out Shorts series with seasons and episodes and said over half of its top 100 creators now have TV as their most-watched screen.
Monetisation policy. YouTube's Partner Programme rules exclude inauthentic content, including AI videos made from generic templates.

What to do about it: Give every video a clear, specific topic so it matches viewers' written prompts. Use A/B testing on titles, thumbnails and edits once it reaches your channel. If you post Shorts in a sequence, group them into a series. Read how to grow on YouTube for more.

What changed in the LinkedIn algorithm in 2026?

LinkedIn replaced its feed's patchwork of models with one system built on large language models. The company described the change on its engineering blog on 12 March 2026: the new system understands what a post is actually about and matches it to members' interests, even when they use different words, and learns from more than a thousand past interactions per member. LinkedIn also said engagement bait and recycled thought leadership would be downranked.

What to do about it: Write posts that go deep on one professional topic rather than broad motivational statements. Use the specific terms your industry uses. Skip "comment YES for the PDF" tactics. Our guide on how to grow on LinkedIn has examples.

What changed in the X algorithm in 2026?

X opened up its ranking code, reduced payouts to aggregator accounts and gave users a way to see whether labels are limiting their reach.

Open-source ranking. On 20 January 2026, X published the code behind its For You feed, which relies on a Grok-based model to predict engagement and filters out blocked, muted and spam-like content. Analysis of the code showed negative signals such as blocks, mutes, reports and "not interested" push posts down, and that the feed limits repeated posts from one author.
Aggregator payouts cut. In April 2026, X's head of product Nikita Bier cut revenue-sharing payouts to aggregator accounts to reward original content.
Under the Hood. On 13 August 2026, X released visibility-filtering code and a tool that shows whether labels have limited your account or posts, for accounts that meet activity requirements.

What to do about it: Post your own takes rather than reposting news with "BREAKING". Avoid anything that makes people mute or block you. Check Under the Hood once a month if you're eligible. More in how to grow on X.

What changed in the Facebook algorithm in 2026?

Facebook formalised what counts as original and said unoriginal content will be shown less. Meta's 12 March 2026 update says content filmed or produced by the Page or profile owner is original, and that reels using other people's material need a creator on screen adding genuinely new information or analysis. Watching along, reacting with facial expressions, stitching clips together, adding borders or changing speed doesn't qualify. Accounts posting mainly unoriginal content may become non-recommendable and lose monetisation. Meta also said it removed more than 20 million accounts impersonating large creators in 2025, and in June 2026 began testing Series for episodic Reels on Facebook and Instagram.

What to do about it: If you run a Facebook Page that shares viral clips, switch to your own footage or reaction videos where your analysis is the main event. Many Nigerian creators cross-post skits to Facebook; if you do, post the original file, not a downloaded copy with another app's watermark.

What do all the 2026 algorithm changes have in common?

They all point the same way: platforms want original content from identifiable people, matched to what viewers say they want. Specifically:

Originality is enforced. Reposting without adding value now costs recommendations or money on Instagram, Facebook and X.
Viewers are in the loop. Topic controls and prompt-based feeds mean you need to be easy to categorise.
AI reads your content. LinkedIn, TikTok and YouTube increasingly use language models to understand what posts are about, so clear, specific language beats vague hooks.
Transparency is growing. Labels for AI content and tools like X's Under the Hood give creators more information, and more responsibility.

How do I tell if an algorithm change hurt my reach?

Compare engagement rates before and after the change date, not just views. A real algorithm effect usually shows up across many posts at once, while a single weak post is more often about the content.

Note the date of the change from this article.
Compare the four weeks before and after it for reach, engagement rate, shares and follows.
Separate follower and non-follower reach where the platform shows it. A drop only in non-follower reach points to recommendation eligibility, such as an originality problem.
Check account status pages, such as Instagram's Account Status or X's Under the Hood, for restrictions.
Change one thing at a time and give it two to three weeks.

A single analytics dashboard that shows all your platforms side by side, like the one in BrainPost, makes these before-and-after comparisons much quicker.

Frequently asked questions

Constantly. Platforms test changes all the time, but only a few are big enough to announce. When X published its ranking code in January 2026, Elon Musk promised updates roughly every four weeks, which shows how often tuning happens behind the scenes.

Is the chronological feed coming back?

Not as the default on the big platforms. Most offer a Following or Favourites view, and Instagram says it keeps ranked feeds roughly in chronological order by weighting recency, but recommendations remain the main way new people find you.

Why did my reach drop even though I post original content?

Algorithm changes are only one cause. Seasonal dips, audience fatigue, weaker hooks and changes in what your competitors post can all lower reach. Look at engagement rates and watch time to see whether the content itself is still landing.

Do algorithm changes affect small accounts more than big ones?

Often they affect small accounts faster, because small accounts rely more on recommendations to non-followers. The upside is that 2026's originality rules favour small creators who make their own content over large accounts built on reposts.

Should I stop using hashtags because of these changes?

No, but don't rely on them. Platforms now read your caption, speech and on-screen text to understand a post. Use a few relevant hashtags as labels and put more effort into clear keywords; see our guide on whether hashtags still work.
