Short answer
Multiply the monthly traffic you lost by your organic conversion rate and value per conversion, then apply a seventy percent recovery factor because full recovery happens in roughly three engagements in ten. If the resulting figure does not exceed the cost of the work over a year, recovery is not the right investment.
Most people never run this calculation. They decide emotionally, because a falling chart feels like something that must be fixed.
Sometimes the maths says spend. Sometimes it says the traffic was never worth what recovering it costs. Both answers are useful.
The four numbers you need
All four are in your own analytics. None requires a tool or an estimate from anyone else.
- Monthly organic sessions lost. Pre-drop average minus current. Use a normal month, not your best one.
- Organic conversion rate. Organic specifically, not site-wide. It is usually different.
- Value per conversion. Average order value, or lead value multiplied by your close rate.
- Cost of the work. Fees, plus internal time, over twelve months rather than one.
The traffic loss calculator does the arithmetic if you would rather not.
Why the seventy percent factor
Because full recovery is the minority outcome. In my engagements:
| Outcome | Roughly how often | What it means for the sum |
|---|---|---|
| Full recovery | 3 in 10 | You get the whole figure back |
| 60 to 90 percent | 5 in 10 | Most of it, eventually |
| Stabilised, no real gain | 1 in 10 | The decline stops. Nothing returns |
| No recovery | 1 in 10 | The spend produced nothing |
Weighting those outcomes lands around seventy percent. Anyone modelling on a hundred percent is modelling the minority case.
A worked example
Numbers chosen to be easy, not typical.
- Lost 8,000 organic sessions a month
- Organic converts at 1.5 percent = 120 conversions
- Each worth $60 = $7,200 a month
- Annual value of the lost traffic = $86,400
- Apply the 70 percent factor = $60,480 realistically recoverable
Against a year of work at $20,000, that is a clear yes.
Now change one number. If those sessions convert at 0.2 percent instead of 1.5, the annual figure is $11,520 and the realistic recovery is $8,064. Against $20,000 of work, that is a clear no.
Same traffic loss. Opposite decision. Volume alone tells you nothing.
What the sum leaves out
Four things, and they push in both directions.
- The wait. A core demotion waits for the next core update. Historically 7 to 147 days. Money spent now may return nothing for months.
- Compounding decline. Doing nothing rarely holds steady. Competitors keep taking ground.
- The work has value anyway. Better content and a cleaner site help paid, email and direct too.
- Opportunity cost. The same budget in paid acquisition produces traffic next week, not next quarter.
That last one is the honest counterweight, and almost nobody in this industry mentions it.
When it is worth it regardless
Three cases where the sum understates the value.
- Organic is most of your acquisition. Losing it is an existential problem, not a channel problem.
- The cause will get worse. A policy violation left in place gets caught again, harder.
- You are selling the business. Organic traffic affects valuation directly.
When it is not worth it
- The traffic never converted. High volume, near-zero commercial value. Common on informational sites.
- The lost market was incidental. Countries you do not sell to. Check before spending anything.
- Demand is falling permanently. Check Google Trends over five years. No recovery reverses that.
- The fix would end the business. Covered in when Google will never bring your traffic back.
Do the cheap diagnosis first
You cannot price the work before knowing the cause. The gap is enormous:
- Technical fault — days of work, recovers in 1 to 4 weeks
- Manual action — weeks of work, then a reconsideration request
- Spam policy violation — cleanup, then 2 to 8 weeks
- Core quality demotion — months of work, then an unpredictable wait
Diagnosis is cheap and often free. Commit to the work only after it. Committing to a twelve month retainer before knowing which of those four you have is how budgets get wasted on the wrong problem.
What different situations actually cost is in what recovery costs.
