Organic vs paid social KPIs: measure each on its own terms

Key takeaways

Organic and paid social need different KPIs because they do different jobs. Track organic on engaged reach, saves and shares, profile visits, messages and enquiries over time. Track paid on cost per result, conversion rate and return against customer value. Report both side by side, but never judge one by the other's numbers.

• Organic KPIs: engaged reach, saves, shares, messages, enquiries.
• Paid KPIs: cost per result, conversion rate, return on spend.
• Shared KPI: enquiries and customers by source.
• Review organic quarterly; paid monthly.

Why do organic and paid need different KPIs?

Organic and paid need different KPIs because organic builds trust and audience over time, while paid buys specific results now. Judging organic on cost per lead makes it look weak; judging paid on likes makes it look pointless. The IPA's research on long and short-term effects supports measuring each on its own horizon.

• Saves and shares per post.
• Profile visits and link clicks.
• Direct messages and comments with questions.
• Enquiries that mention social.

What KPIs should you track for paid?

Track paid on the objective you bought. GA4 key events and platform conversion tracking show actions after the click.

• Cost per enquiry, booking or sale.
• Click-through rate.
• Landing page conversion rate.
• Return on ad spend against margin.
• Frequency, to spot fatigue.

• Break-even ROAS: the return your social ads must make

What should both share?

Both should share a bottom line: enquiries and customers by source, and cost per customer where you can calculate it. This is the number that tells you whether social media as a whole is paying back.

• How many of your enquiries come from organic vs paid?

How often should you review each?

Review paid monthly, because spend is ongoing and changes have quick effects. Review organic quarterly, because trends take time to show. A short weekly check on both catches problems early.

What does this look like in practice?

A pattern we see: an architect's practice reported organic and paid together as total likes and followers, which said nothing useful. Splitting the report, organic on enquiries mentioning posts and paid on cost per consultation booked, showed both were working and stopped a plan to cut organic.
