Measuring social ROI beyond likes: the 5 real metrics

Likes and followers are vanity metrics. An SME with 50,000 followers that doesn't generate enquiries is a cost. One with 1,500 followers bringing 4-8 leads/month is an asset. Here are the 5 metrics that separate the two cases and how to measure without spending.

1. Organic traffic to site from social

In GA4: Acquisition > Traffic sources > filter session_source = facebook, instagram, linkedin, tiktok. Minimum target: 50-100 visits/month from relevant social. Below that, you're not doing enough volume or copy doesn't drive clicks.

2. Leads attributed to social

Setup tracking: every bio link, post, story must have UTM parameter (e.g. ?utm_source=instagram&utm_campaign=reel-march). In GA4 see how many leads come from social, separated by platform. Goal threshold: 5-10% of total leads from social for non-ecommerce businesses.

3. Conversions (not just leads)

Leads ≠ customers. Calculate: social leads → quotes → closed customers. If you have 100 leads/month from social but only 2 close, social brings volume but not quality. Likely: targeting too broad or wrong offer for that channel.

4. Share of voice in your sector

Monthly, count: how many times your brand is mentioned (Google, social mentions) vs 3 direct competitors? Free tools: Google Alerts + manual LinkedIn searches. For SMEs: target 15-30% share of voice in your niche segment.

A serious SME measures traffic, leads, conversions, share of voice and qualitative mentions. Likes and followers are accessories. See the GA4 tracking guide.
