Social media metrics that matter (and the ones that don't)

Which metrics actually predict business outcomes?

The academic evidence draws a sharp line between attention and intent. In the Journal of Marketing, Colicev, Malshe, Pauwels and O'Connor tracked brands' owned and earned social media alongside consumer mindset metrics and found that social media activity moves measures such as brand awareness, purchase intent and customer satisfaction, and that these mindset metrics in turn are linked to shareholder value, with owned and earned media playing different roles [1]. In other words, social media does connect to business results, but through metrics that reflect what people think and intend, not through applause.

The clearest evidence against the applause metrics comes from a Journal of Marketing Research study by John, Emrich, Gupta and Norton. Across a series of experiments they found that "liking" a brand on Facebook did not cause more favourable attitudes or more purchasing; instead, pre-existing fondness for the brand predicted both the liking and the buying [2]. A like is a symptom of interest, not a cause of it. Metrics worth privileging are the ones tied to behaviour: engagement rate on your content, reach into new accounts, click-throughs, and downstream actions like enquiries or sales.

What is a good social media engagement rate?

The standard formula used by large benchmark studies is engagement rate by follower: total interactions on a post (likes, comments, shares, reactions) divided by total follower count [3, 6]. Some analysts also compute engagement rate by reach or by view, which corrects for how many people actually saw the post; on video-first platforms this is often the fairer measure [5].

The most widely used large-sample benchmarks come from Rival IQ's annual Social Media Industry Benchmark Report, which for 2025 sampled 150 companies in each of 14 industries from a database of over 200,000 companies, covering millions of posts [3]. The 2025 medians across all industries: Instagram 0.36% engagement per follower [4], and TikTok 1.73% per follower, or 3.4% measured by view, making TikTok roughly five times more engaging than the next platform [5]. Facebook sits far lower; the 2024 edition of the same report put the all-industry median at 0.063% [6]. Two practical implications follow. First, never compare your Instagram rate to your Facebook rate as if they share a scale. Second, single-digit fractions of a percent are normal, so judge yourself against your industry median and your own trend line, not against viral outliers.

What is the difference between reach and impressions?

Reach is the number of unique accounts that saw your content at least once. Impressions are the total number of times the content was displayed, counting repeat views by the same person [7]. Meta documents impressions for advertisers in its official Business Help Centre [8], and in Instagram's insights the reach concept appears as "accounts reached", counting each account once no matter how many times it viewed the content [7].

The ratio between them is quietly useful. Impressions divided by reach gives average views per person. A high ratio can mean your content rewards repeat viewing, or that you are recycling the same audience; a ratio near one with growing reach means you are consistently getting in front of new people. Neither number alone is a goal, but reach growth among non-followers is one of the better organic signals that your content is travelling.

Which metrics are vanity metrics?

A vanity metric is any number that rises without telling you whether anything of value happened. Follower count is the canonical example: the experimental evidence shows that acquiring a follow or a like does not in itself shift attitudes or purchasing [2]. Raw like totals are similar, because they scale with audience size and post volume; that is exactly why benchmark studies normalise engagement by followers before comparing brands [3]. Impressions inflated by repeat views from the same accounts can also flatter a report while reach stays flat [7].

None of these numbers is useless. They are context, not outcomes. The test to apply to any metric is simple: if it doubled tomorrow, would you expect anything in the business to change? If the honest answer is no, it belongs in the footnotes of your report, not the headline.

How often should you review your analytics?

More often than never and less often than daily. Day-to-day engagement is noisy, and the large benchmark studies that define "normal" performance are built on months of data precisely because single posts vary so much [3]. A sensible cadence for most small teams is a short weekly scan (what ran, what reached new accounts, anything unusual worth repeating) and a monthly review of trend lines: engagement rate against your industry median, reach growth, and clicks or enquiries attributable to social.

The monthly review is where decisions live. Because engagement norms differ by platform by an order of magnitude [4, 5, 6], review each channel against its own history and its own benchmark, and let the cross-channel comparison be about where your effort earns the most reach and action per post, not whose percentage is bigger.

Enki Socials' analytics view is built around exactly this shortlist, tracking reach, engagement rate and top posts per channel so your weekly scan takes minutes instead of a spreadsheet.
