Median Engagement Rates for 2025: LinkedIn Leads at 6.2%, X Trails at 2.5%

LinkedIn delivered a median engagement rate of roughly 6.2% in 2025, more than double X's 2.5%, according to Buffer's State of Social Media Engagement report, which analyzed 52+ million posts from over 200,000 accounts. The full platform ranking: Facebook at ~5.6%, Instagram at ~5.5%, TikTok at ~4.6%, Pinterest at ~4.0% and Threads at ~3.6%.

The year-over-year shifts matter as much as the levels. X's median climbed about 44% versus 2024 and Pinterest's rose roughly 23%, while Instagram fell around 26% and Threads dropped about 18%. Buffer cautions that each platform defines engagement differently, so practitioners should compare their numbers within a platform, not across them.

What separates metrics from KPIs?

Buffer's guide, updated by Rochi Zalani in November 2026, frames the distinction plainly: metrics are everything you can measure; KPIs are the three to five numbers tied to a goal and a target. An example the guide gives: lift LinkedIn engagement rate from 4% to 6% in a quarter.

Vanity metrics — follower count, raw likes, a single post's impressions — only become useful when converted into rates. The guide's rule of thumb: if a number can rise without changing what you'd do next, it's a vanity metric on its own.

Which behaviors move the numbers?

The dataset links two habits to better performance:

• Replying to comments. Posts where the account replied earned more engagement than the same account's posts without replies — up to 42% more on Threads, 30% on LinkedIn and 21% on Instagram. Buffer flags this as correlation, not proven cause, but it held across every platform studied.
• Posting consistently. Across 4.8 million channel-weeks, accounts that skipped a week grew followers more slowly than their own baseline. On LinkedIn, moving from one post a week to two to five meant about 1,182 more impressions per post.

Practitioners quoted in the guide reinforce the pattern. Hailley Griffis, Buffer's Director of Communications and Content, said: "If you are reaching an increased number of people, then you're doing something right." She reviews reach every couple of weeks and reports her Threads reach keeps climbing the more consistently she posts.

Meryoli Arias, Head of Social Media at Glide, treats impressions and follower growth as her north-star metrics — but learned their limits from a viral post that hit 2 million impressions without lifting click-throughs or sign-ups. "Virality is not and should never be the goal of social media," she said.

How do the formulas work?

The guide walks through 20 metrics, from engagement rate (total engagements ÷ reach × 100) to return on ad spend. Worked examples include:

• CPC: $50 spent on an ad with 100 clicks equals 50 cents per click.
• CPM: $200 spent across 40,000 impressions equals a $5 CPM.
• ROAS: $5,000 revenue from a $1,000 Facebook campaign equals 500%.
• Share of voice: 300 brand mentions against 900 competitor mentions equals 25%.

Digital marketing consultant Laura Holyer advises treating platform-reported ROAS "with a pinch of salt" given cookie restrictions and missing conversion data. She prefers Blended ROAS — total revenue across all channels ÷ total ad spend — such as $8,000 revenue on $1,000 spend equaling 800%.

Reach and impressions also need separating: reach counts unique viewers, while impressions count every display, including repeats. Several platforms, including Instagram, TikTok and YouTube, now lead with "views" instead, counting each slightly differently.

What's the recommended routine?

Buffer's closing method: pick one quarterly goal, choose three to five matching metrics, record baselines before setting targets, check content metrics weekly and KPIs monthly, and change one variable at a time. Freelance marketer Rebecca Broad sums up the creative filter: "Why would someone who sees this post stop scrolling and spend precious time and energy engaging with it?"

As platform medians keep shifting — Instagram's 26% decline being the sharpest — Buffer suggests checking whether a dip reflects your content or the platform-wide trend before rewriting your strategy.
