A new Hootsuite evaluation from 13 October 2026 puts 4,2 % engagement on Instagram, 3,9 % on LinkedIn and 1,5 % on TikTok. Anyone who concludes that Instagram is generally the most interactive platform overlooks a crucial caveat: according to Hootsuite, the figures refer to the best-performing content type and calculate interactions relative to follower count. They therefore do not necessarily describe the average of all posts from an account.
For German social media teams, this distinction matters more than the ranking: benchmarks are only useful for budget and content planning if the numerator, denominator, formats and comparison group match.
What the new industry values actually say
Hootsuite publishes values for 13 industries and five platforms. Some particularly informative examples from the evaluation:
| Industry | Instagram | LinkedIn | TikTok | | --- | ---: | ---: | ---: | | Marketing agencies | 3,7 % | 4,7 % | 0,7 % | | Technology | 4,2 % | 3,9 % | 0,7 % | | Retail/consumer goods | 3,6 % | 4,3 % | 1,6 % | | Construction/mining/manufacturing | 5,2 % | 4,0 % | 2,6 % |
These values are not a forecast for an individual brand account. The industry mix, account size, content format and geographic target audience can all shift the rate. Even a high engagement value proves neither reach growth nor revenue.
Why Socialinsider and Buffer deliver different numbers
The deviations show how little a supposedly universal engagement average tells you. Socialinsider analyses, by its own account, around 70 million posts and reports, for the comparison of 2025, among other things 0,48 % on Instagram and 3,7 % on TikTok. The calculation is likewise based on followers, but on a differently defined selection of organic posts and with interaction types that vary by platform.
Buffer evaluates more than 52 million posts for its report published in March 2026 and cites for 2025, among other things, roughly 5,5 % for Instagram, 6,2 % for LinkedIn and 4,6 % for TikTok. These are predominantly median values based on the accounts reached and, moreover, exclusively posts from Buffer's dataset. These figures cannot be directly set against Hootsuite's follower-based format selection.
It would therefore be wrong to construct a new averaged platform ranking from the three publications. Hootsuite also does not transparently disclose a separate sample size and survey period for every figure on its publicly accessible benchmark page.
Three rules for a reliable benchmark
First: fix the denominator. `Interaktionen / Follower` answers a different question than `Interaktionen / erreichte Konten`. For paid advertising, the impression-based rate may also be meaningful. Platforms already count interactions differently.
Second: compare like with like formats. An organic Instagram carousel series should not be placed uncritically in the same comparison group as Reels, TikTok videos or paid creatives. Separate time series per format and audience are helpful.
Third: don't confuse engagement with impact. Comments, saves and shares are different signals. If a company wants to generate leads, sales or new customers, it additionally needs click and conversion data and – where possible – controlled impact measurement. Our guide to social media goals and KPIs explains this distinction; the IAB debate on creator measurement standards shows the same problem with influencer campaigns. How little pure interaction reveals about sales is also shown by the e.l.f. "Magical Sisters" campaign.
What teams should concretely check now
Instead of copying a 4,2% target value into every report, companies should build their own benchmark from the last three to six months: group organic posts by platform and format, document the median and spread, account for size classes and additionally report the business metric they care about. External industry values are a plausibility check – not a universal proof of performance.
