Instagram Algorithm Update October 2026: What Businesses Need to Know

Has your Instagram reach changed? Wondering how the Instagram algorithm works in 2026 or what you should be doing differently?

Instagram continues to change how it ranks and recommends content. For businesses, the biggest takeaway is simple: creating genuinely engaging, original and shareable content matters more than chasing algorithm hacks.

Here are the key Instagram algorithm updates and trends businesses should be thinking about in 2026.

1. Watch time matters

For Reels, getting somebody to stop scrolling is only half the battle. You need to keep them watching.

That makes the first one or two seconds particularly important.

Instead of:

"We recently visited..."

Try:

"You probably didn't know this was here..."

"5 places you need to visit this autumn..."

"Send this to whoever you're doing half term with."

Show the best footage early and give viewers a reason to stay until the end.

2. Shares and sends are incredibly valuable

When analysing Instagram performance, don't focus solely on likes.

Ask: did somebody find this useful or interesting enough to send to another person?

Shareable content is often:

• Useful

• Surprising

• Relatable

• Planning-focused

• Newsworthy

Think "Shall we do this?" or "You need to see this!"

Our advice? Don't just create content people like. Create content people need to send to someone.

3. Original Instagram content is important

Original content should be at the heart of your Instagram strategy in 2026.

Rather than relying heavily on reposted promotional graphics or other people's videos, create your own:

• Reels and photography

• Voiceovers

• Reviews and experiences

• Educational carousels

• Behind-the-scenes content

• Commentary and recommendations

Businesses should increasingly think like content creators rather than advertising noticeboards.

4. Don't overlook Instagram carousels

Reels aren't your only opportunity for reach and engagement.

Carousels are ideal for useful content people want to save or send, such as guides, recommendations, tips and lists.

And make your first slide about the information, not your branding.

Instead of:

YOUR BRAND – OCTOBER HALF TERM

Try:

12 BRILLIANT THINGS TO DO THIS OCTOBER HALF TERM

Your brand isn't always the hook. The information is.

5. Instagram SEO matters

If you want people to discover your content, consider what they're actually searching for.

Instead of:

"Half term fun incoming!"

Try naturally incorporating a phrase such as:

"Things to do in Dorset this October half term."

Include relevant locations, business names, events, dates and descriptive keywords within your captions.

Hashtags can still provide useful context, but huge blocks of hashtags aren't a growth strategy. Focus on a small number of genuinely relevant hashtags alongside strong content and descriptive copy.

6. Stop judging posts purely on likes

If you're reporting on Instagram performance, go beyond:

"This Reel got 800 likes."

Instead, look at:

Reach | Non-follower reach | Average watch time | Likes ÷ reach | Sends ÷ reach | Followers generated

These metrics tell you much more about whether your content is actually helping your account grow.

And don't panic if a post starts slowly. Unless there's an actual mistake, give your content time rather than deleting it because it hasn't performed immediately.

The Instagram checklist we use

Before publishing, ask:

STOP – Why will somebody stop scrolling?

STAY – Why will they keep watching or swiping?

SEND – Why will they send it to somebody?

SEARCH – Is it clear what and where this content is about?

SOURCE – Is it genuinely original content?

If you can't confidently answer the first three, the post probably isn't ready.

So, what does the Instagram algorithm want in 2026?

There's no secret Instagram algorithm hack.

Create content worth watching, saving and sharing.

The businesses succeeding on Instagram are increasingly behaving like publishers and creators, not advertisers, producing content their audiences actively choose to consume.

Instagram Algorithm FAQs

How does the Instagram algorithm work in 2026?

Instagram uses different ranking systems across Reels, Feed, Stories and Explore. Rather than trying to find one algorithm hack, businesses should focus on creating content that generates strong signals such as watch time, engagement, shares and sends.

What does the Instagram algorithm prioritise?

Some of the most important signals include whether people stop and engage with your content, how long they watch it and whether they share or send it to other users. Creating relevant, original content should therefore be a priority.

How can I increase my Instagram reach in 2026?

Start with stronger hooks, create original Reels and carousels, improve audience retention and produce content people genuinely want to share. You should also use descriptive captions and relevant keywords to help Instagram understand your content.

Are hashtags still important on Instagram?

Hashtags can still provide useful context, but they shouldn't be relied upon as your main Instagram growth strategy. Focus on relevant hashtags rather than large blocks of generic terms, alongside strong content and clear keywords.

Do Reels still get more reach on Instagram?

Reels remain an important format for discovery, but they aren't the only way to grow. Carousels can also perform strongly, particularly when they contain useful, saveable or highly shareable information.

Why has my Instagram reach suddenly dropped?

A drop in reach doesn't necessarily mean you've been penalised. Look at factors such as watch time, audience retention, non-follower reach, shares, sends and the strength of your opening hook. Individual posts can also take time to find their audience.

Does Instagram prefer original content?

Creating original content is increasingly important. Businesses should prioritise their own videos, photography, commentary, voiceovers, experiences and creative concepts rather than building their strategy around reposting existing content.

What is Instagram SEO?

Instagram SEO means helping Instagram and users understand what your content is about. Using clear, natural keywords alongside locations, business names, services, events and other relevant information can make your content easier to discover.
