An influencer conversion rate is the conversions an influencer sent divided by the visits they sent, shown as a percentage. Type both numbers above and the calculator shows the rate to two decimal places. Add what one sale or signup is worth and it also shows the estimated revenue. It works as you type and needs no signup.
Count visits and sales for one influencer
- Give each influencer a link of their own with UTM tags. Google says to always set utm_source, utm_medium and utm_campaign. Put the creator's name in one of them so each creator gets their own row in your reports.
- Keep the values lowercase. Google Analytics treats utm_source=google and utm_source=Google as two different sources, so one creator can end up split across two rows.
- Take the visits and conversions for that one link from your analytics, or count orders on the creator's discount code, and type them above.

Fees, followers and engagement are left out
It doesn't price an influencer or work out an engagement rate. To estimate a creator's fee from their followers and likes, use an influencer rate calculator. This one only measures what happened after people clicked.
It can't see your analytics or the influencer's account, so it uses only the numbers you type. It also doesn't subtract the fee you paid. Compare the revenue figure with that fee yourself to see whether the post paid for itself.
