7 social media metrics that actually move the needle

Executive overview

Likes and impressions feel good but rarely drive business growth. The metrics that matter are the ones tied to reach quality, content amplification, and return.

Track these seven numbers to stop guessing and start optimising your social media output.

Post performance only matters when measured against the right metrics — not vanity counts.

The 7 metrics to track

1. Reach — total people who see your content. Ask: are you reaching enough people, and are they the right fit? Compare follower vs non-follower breakdown and check whether your audience matches your target demographic.

2. Impressions — how often content is displayed. Benchmark against platform-wide trends: if a platform's impressions drop 20% but yours hold flat, you're outperforming the market.

3. Engagement rate — likes and comments as a percentage of followers. Facebook benchmark: 0.06%. Instagram: 0.68%. Ignore benchmarks; compare directly against competitors. If a competitor gets 1,000 likes with 100,000 followers, their rate is 1% — beat that.

4. Amplification rate — shares per post divided by total followers. Shows which content your audience actively spreads. Create more of what gets shared, less of what doesn't.

5. Virality rate — shares as a percentage of impressions (not followers). Distinct from amplification: measures spread relative to exposure, not audience size.

6. Audience growth rate — new followers over a period as a percentage of total audience. TikTok is the fastest-growing network, with 105% user growth in the US over recent years.

7. Social referrals — purchases or leads driven by others recommending your product. Consumers are 71% more likely to buy based on a social referral. Treat it like a public review or Amazon rating.

Bonus metric: ROI

ROI is the most important number. Track which posts generate conversions using Google Analytics goal and conversion tracking. Supplement with post-purchase surveys asking customers how they found you. Combining both gives a clear picture of which channels and content types deliver the highest return.
