A ranking is worth the clicks it earns multiplied by what those clicks would cost you in Google Ads. It is the only way to put organic search and paid search on the same scale, and the only version of the argument a finance director will accept.
“Organic traffic went up 40%” approves no budgets. “This position saves us $4,000 a month in ads we would otherwise have to buy” approves budgets.
Organic traffic is not free. It is prepaid.
The clicks carry no per-click charge, which is not the same as costing nothing. You pay in content, technical work, links and months of waiting, and you pay before anything arrives. Paid search is the reverse: instant, and it stops the day you stop paying. Treating one as free and the other as expensive is how businesses end up with neither done properly.
The click-through curve
Position determines how much of the search volume actually reaches you. Averages compiled across large samples of results generally land near these figures:
| Position | Typical share of clicks |
|---|---|
| 1 | ~28% |
| 2 | ~16% |
| 3 | ~11% |
| 4 | ~8% |
| 5 | ~6% |
| 10 | ~2.5% |
Treat these as a shape, not a promise. Branded searches run far above; crowded commercial results with shopping units and ads above them run well below. Your own Search Console performance report gives you the real figures for your own pages, and you should use those the moment you have them.
The shape is what matters. Moving from position five to position three roughly doubles your traffic. Moving from three to one roughly triples it again. That non-linearity is the entire business case for the last stretch of SEO work, and it is why “we are on page one” is not a result on its own.
Pricing a ranking: a worked example
Take a keyword with 8,000 monthly searches, a Google Ads cost per click of $1.40, a page that converts at 2.5%, and an average order of $60. Assume 20% of searches end without any click at all — more on that below.
- Searches that produce a click: 8,000 × 80% = 6,400
- Clicks at position 3: 6,400 × 11% = 704
- Cost of the same clicks from Google Ads: 704 × $1.40 = $986 a month
- Annual equivalent: $11,827
- Orders: 704 × 2.5% = 17.6 a month
- Revenue: 17.6 × $60 = $1,056 a month
Now compare positions on the same keyword:
| Position | Clicks / month | Revenue / month | Ads cost avoided / year |
|---|---|---|---|
| 1 | 1,766 | $2,650 | $29,676 |
| 2 | 1,011 | $1,517 | $16,988 |
| 3 | 704 | $1,056 | $11,827 |
| 5 | 403 | $605 | $6,774 |
| 10 | 160 | $240 | $2,688 |
One keyword. The gap between position five and position one is about $23,000 a year in traffic you would otherwise buy. Our SEO traffic value calculator runs this for your own keyword, including the position ladder.
Zero-click searches and AI Overviews
A growing share of searches are answered on the results page itself, by an AI Overview or a featured snippet, and never produce a click for anyone. Any traffic forecast written in 2026 that ignores this is wrong before you finish reading it, which is why the calculation above has an explicit allowance for it.
The effect is uneven. Informational queries — “what is”, “how does”, “why” — lose the most, because a short answer satisfies the searcher completely. Commercial and transactional queries lose the least, because somebody who wants to buy still has to reach a page that sells the thing. If your keywords are mostly the second kind, your exposure is lower than the headlines suggest.
Google’s own position is worth reading directly rather than through summaries. Its documentation on AI features and your website states that pages must be indexed and eligible to appear with a snippet to be cited in AI Overviews or AI Mode, and that there are no additional technical requirements. Its guide to optimising for generative AI features is blunter still: the best practices for SEO remain the best practices, because the AI features are built on the same ranking and quality systems.
We go through this in detail in how to show up in AI Overviews. The short version: the practical answer to “how do I optimise for AI search” is the one nobody selling a course wants to give: do the ordinary work properly. Be crawlable, answer the question directly and early, structure the page so a machine can find the answer without guessing, and be the kind of source worth citing. The SEO Starter Guide has not changed its advice, and that is the point.
SEO or Google Ads?
The framing is wrong, but the comparison is useful, so here is how the two differ on the things that decide a budget.
| SEO | Paid search | |
|---|---|---|
| Time to first result | Months | Hours |
| Cost per click | None, after the work | Every click, every time |
| What happens if you stop | Decays slowly | Stops the same day |
| Testing a new offer | Slow and indirect | Immediate |
| Position you can buy | Earned only | Top of page, today |
For a business that needs revenue this quarter, paid advertising is the only honest answer, and the question becomes whether the unit economics work — which is what break-even ROAS decides. For a business that wants the cost per acquisition to fall over time rather than rise, SEO is how that happens. Most companies that do well run both and let paid search fund the wait.
What this calculation leaves out
- It prices one keyword. A page that ranks for one term usually ranks for dozens of variations, so the real figure is normally higher — often several times higher.
- It ignores the cost of getting there. Value is not profit until you subtract the work.
- It assumes the page converts. Traffic to a page that does not convert is a cost, not an asset. Fixing that is a web design and conversion job, and it usually pays back faster than the ranking does.
- It treats cost per click as fixed. Ad auctions move, and so does the value of avoiding them.
Frequently asked questions
How do I find my real click-through rate?
Search Console, performance report, filtered to the query and page you care about. It gives impressions, clicks, average position and the CTR those produce for your site specifically. Always better than an industry average.
Does ranking in AI Overviews bring traffic?
Being cited puts your name in front of the searcher and produces some clicks, though fewer per impression than a traditional listing. Google states there are no special requirements to be eligible beyond being indexed and snippet-eligible, so the work is the same work.
Is it worth targeting a keyword with low volume?
Often yes, if the intent is commercial. Two hundred searches a month from people ready to buy are worth more than twenty thousand from people browsing. Run both through the traffic value calculator and compare the revenue line rather than the click line.
How long does it take to reach page one?
For a new site on a competitive term, longer than any agency should promise. Technical fixes can move impressions within weeks; authority takes months. Anyone quoting a date has not looked at your site or the competition.

Price the keyword you are arguing about with the SEO traffic value calculator, then compare it with what the same traffic costs you today through ads. If organic is worth many times what you are spending to win it, that is the business case. If it is not, you have saved yourself a year. We will go through it with you in a free audit.
