What a search click is actually worth to you
You need to put a number on organic traffic to justify the work or compare it against paid.
Short answer
Value a click by what it produces, not by what an ad would cost. Multiply sessions by your conversion rate by the value of a conversion, and do it per page rather than site-wide, because averages hide the fact that a handful of pages produce almost everything. Ad cost equivalence is the most quoted method and the least defensible.
The method that actually holds up
Sessions times conversion rate times value per conversion. Every term is measurable on your own site and none of them requires a competitor benchmark. Do it per page or per query cluster: the site-wide average is dominated by your few winners and describes nothing accurately.
Why ad-cost equivalence inflates everything
"This traffic would cost X in ads" assumes the ad click and the organic click are equivalent, which they are not: different position, different intent, different trust, and different conversion rate. It also assumes you would have bought that traffic, which for most head terms you would not at any price.
Value the asset, not the month
Organic traffic keeps arriving after you stop working on the page. A fair valuation counts the stream, not one month of it, discounted for the fact that rankings decay without maintenance. This is the argument that makes SEO look reasonable against paid, and it is also the honest one.
Segment brand out first
Brand searches convert far above everything else and would largely have arrived anyway. Including them in your average makes every non-brand page look better than it is, and it is the single most common way an SEO business case gets inflated.
Not all conversions are equal
A free-tool completion is not a signup, and a signup is not revenue. Value each step separately, or you will justify traffic that produces activity and no money, which is a comfortable place for an SEO programme to sit indefinitely.
The number that changes decisions
Value per page, sorted descending. It tells you which pages to protect, which to improve, and which to stop maintaining. A single site-wide figure cannot answer any of those, which is why it is the number most often reported and least often used.
Be honest about attribution
Search is rarely the only touch. Someone who found you through search, left, and returned via a bookmark converts as direct. Any valuation that ignores this understates search; any that claims full credit overstates it. Say which you did.
Questions
- Should I use Google Ads CPC as a proxy?
- Only as a rough upper bound, and label it as one. The organic click and the paid click differ in intent and trust, and CPC reflects what advertisers will pay rather than what the visit produces for you.
- How do I value traffic with no conversions?
- By whatever it actually produces: signups, downloads, mentions, links. If it produces nothing measurable, its value is genuinely unclear and that is a finding worth acting on rather than papering over.
- What about brand searches?
- Value them separately. They convert best and they are largely the result of other work, so folding them into an average makes your content look more effective than it is.
Measured, not asserted
ihatepdf.cv had no revenue to attribute, which made the valuation question unusually clean: 26.92% of 132,748 sessions ended in a completed task, from 42,320 search clicks. The number that mattered was not a click value but the completion rate, because that was the only outcome the product actually produced.
