[What Data Says] Social Media Reach Has a 14% YoY Decrease on Instagram

Instagram and Facebook are some of the oldest platforms in social media marketing, but a question that I get a lot is: are they still relevant? Well, if you know me, you know I like to always turn to data for these types of questions.

So, in this study, I'm going to take a peek at a couple of reach benchmarks, namely the average reach rate in 2026 and beyond, offering a data-driven look at how reach on social media is changing and what it means for brands moving forward. I'll also be covering how organic social media reach breaks down by page size and content format across Instagram and Facebook, and what strategies actually move the needle.

And lastly, but not least, expect to see where engagement by reach is headed these days. Let's dive in!

How to calculate your social media reach rate?

Calculating social media reach can be tricky, considering that reach data (regardless of the social media reporting tool you're using, Meta Business Busite included) is estimated data.

considering that this metric only takes into account unique users who were exposed to your content.

The average reach rate can be calculated by dividing the total reach of a post by the total number of followers and multiplying the result by 100.

Is organic reach on social media decreasing?

Over the last couple of years, several social media studies have emphasized Instagram's superiority in performance compared to Facebook.

Whether for its increased reach, engagement rate, and many other KPIs, Instagram has proven to be the better choice for marketing purposes.

But while it is true that Instagram generates a reach 2x higher compared to Facebook, our data shows that organic reach on social media continues to soften year over year, across both these major platforms.

As of mid 2026, while Facebook's average reach rate stands at an average of 1.80%, Instagram, with an average reach rate of 4.90%, scores a 14% year-over-year decrease.

Reach rate by brand size on Facebook and Instagram

Not every page is playing the same game. A brand-new account with a couple thousand followers and an established page with a million followers see very different reach, purely because of how the reach rate math works.

Here's what that looks like in practice:

And the takeaway here is that the smaller the page, the bigger the slice of its audience it reaches. On Instagram, pages in the 1-5K bracket pull a 6.65% reach rate, nearly double what pages in the 100K-1M range see. Facebook's drop-off is even sharper, falling from 4.35% for the smallest pages to just 0.50% for the biggest ones.

Instagram also drives roughly 2x more reach than Facebook at almost every size bracket, and the gap only widens as pages get bigger.

Reach rate by content format on Facebook and Instagram

Format is one of the biggest levers brands have over their organic social media reach, since the algorithm treats different content types differently. But the two platforms don't reward the same formats, and the results aren't always what you'd expect.

Average reach rate for Instagram

Don't know if you saw this coming, but according to Socialinsider's data, Carousels are the best format for driving higher reach on Instagram, edging out Reels despite all the attention Reels get as the platform's supposed reach-growth engine. Static images bring up the rear, but the gap across all three formats is narrower than you might think.

Average reach rate for Facebook

On Facebook, single images and albums work best for generating increased reach, with values tied at the top. Reels underperform here too, and link posts trail every other format by a wide margin, which tracks with Facebook's long-standing habit of deprioritizing content that sends people off-platform.

The common thread across both platforms: Reels don't deliver the reach advantage their reputation suggests. If your content calendar is built around the assumption that Reels are the default reach play, these numbers are a good reason to test that assumption against your own data.

Social media reach vs. engagement

Reach and engagement are two social media metrics that answer two different questions. Reach tells you how many unique people saw your content; engagement tells you how many of those people did something about it, whether that's a like, a comment, a share, or a save.

A page can have high reach and low engagement (lots of people scrolled past) or lower reach and high engagement (a smaller audience that's genuinely invested). Neither number tells the full story on its own, which is why I would like to also bring to the table some engagement-by-reach benchmarks as well.

On Instagram, engagement by reach is on a continuously decreasing path, sliding from 3.70% in January 2025 down to 3.20% by August 2026, with only small, short-lived rebounds along the way.

Facebook tells a messier story: reach rate held fairly flat through most of 2025, spiked sharply in spring 2026, then pulled back down to 1.25% by August, close to where it started.

How to track reach data?

The most straightforward way to measure reach in social media is through each platform's own native insights, whether that's Instagram's Professional Dashboard or Facebook's Meta Business Suite.

Within Meta specifically, reach is also split between organic and paid, both at the page level in Meta Business Suite and at the post level, so you can isolate what your content is earning on its own from what your ad spend is adding on top.

And while the native platform's data are a good starting point for measurement and performance understanding, a third-party analytics tool becomes essential for additional reach data beyond the raw number. With Socialinsider, for example, you can get reach trend data, performance across formats, and even competitive benchmarks to see how you stack up against your actual competitors.

How to increase your social media reach?

Wherever your reach numbers currently stand, there's room to grow them. Boosting organic reach on social media takes a mix of strategy and creativity, and here are a few strategies to help you improve your numbers.

• Lean into the formats that drive reach: As the format breakdown above shows, not all content pulls its weight equally when it comes to reach on social media. Once you know which format performs best for your page size and platform, shift more of your calendar toward it rather than splitting effort evenly across formats.
• Feature UGC (user-generated content): One of the most effective ways to increase social media reach is by featuring user-generated content (UGC). This tactic not only builds trust but also encourages more engagement, which boosts reach further. When users see real customers using and endorsing your products, they're more likely to engage with your posts and share them with their networks.
• Have a strong Instagram SEO strategy: A strong Instagram SEO strategy can significantly improve your reach. By optimizing your profile, captions, and hashtags for relevant keywords, you can ensure your content gets discovered by users searching for specific topics.

Final thoughts

So, are Instagram and Facebook still relevant? The data says yes, but not in the same way for every brand. Reach behaves differently depending on your page size, the platform you're on, and the formats you lean on, which means the "right" benchmark isn't a single number pulled from this article, it's the bracket that actually matches your situation.

Treat these figures as a starting point rather than a verdict. Check back against them periodically, watch how your own reach and engagement move relative to your size and format mix, and let that comparison guide where you invest your effort to grow social reach next.

FAQs on social media reach

What is social media reach?

Social media reach represents the total number of unique users who have been exposed to a piece of content, post, or advertisement on a social media channel within a selected timeframe. Unlike followers or impressions, it gives you a more accurate count of the people you've actually impacted.

Why does social media reach matter?

Reach lets you see how effective a campaign is in real time, gauge the impact of influencer or brand partnerships, and estimate how many active followers you really have. Compared to impressions, it paints a more realistic picture of performance because it counts each person only once.

What's the difference between organic and paid reach on social media?

When people talk about reach in social media, they're usually referring to one of two flavors: social media organic reach, the unique users who see your content without any paid promotion behind it, driven by your existing followers, shares, hashtags, and the platform's algorithm, and paid reach, the unique users who see your content because you paid to put it in front of them. Organic social media reach is the harder number to move, which is why it's the one brands watch most closely, and the one this study focuses on.
