Full-Stack Marketing & TechnologyWhat is each Google result actually worth?
SERP Traffic puts a badge under every result on a Google search page, showing the visits that result is modelled to earn from the query you just typed — and reducing it when an AI Overview is taking the clicks. Every figure is modelled from published data, never measured, and the badge says so. No account, no email.
It is not in the Chrome Web Store yet. This page describes what it does and exactly how the estimate is produced, so you can decide whether it is worth your toolbar before it is available.
One line under each result
Search for anything. Under each organic result a badge appears reading something like ~20K/mo, followed by the position, the click-through rate used, and the monthly search volume it was worked out from. Hovering names the studies behind both halves of the sum.
When Google is showing an AI Overview on the page, the badges turn amber and every estimate drops by 35%, because that is roughly what the measured click-through loss is on those pages. The colour change exists so a lower number has a visible reason rather than looking like a bug.
Below position 10 the badge says it has no estimate. That is not a failure — see what it deliberately does not do.
How the estimate is produced
There is no proprietary model and nothing is hidden. The whole calculation is one multiplication:
Estimated monthly visits = monthly search volume × click-through rate for that position, and the click-through rate is reduced by 35% when an AI Overview is on the page.
What the traffic would cost to buy
Each badge also carries a second figure: those same visits multiplied by the term’s Google Ads cost per click. It answers “what would I pay to get this traffic from ads instead”, which is the question that makes an organic position feel like a number rather than a rank.
It is not revenue. Cost per click is what advertisers pay for a click on that term. Nobody bills you when someone arrives from an organic result, and the person who clicks a result is not the person who clicks an ad. Treating the two as equivalent is a convention of the industry, not a fact, so the extension labels the figure “to buy” and never “value” or “worth”.
The strip at the top of the page
Three of these numbers belong to the search term rather than to any one result — its monthly volume, what advertisers pay per click for it, and how contested it is — so they are identical under every result on the page. Repeating them ten times would teach you to stop seeing them, so they are drawn once, above the results.
That strip is also where you find out what a keyword would cost to bid on, without opening Keyword Planner. The per-click figure is a guide to what a click costs rather than a recommended bid: Google sets the real price at auction, and yours depends on your quality score and on who else is bidding that day. The currency is whichever one the data provider reports for the market you have selected — the strip prints the market code beside the figure rather than converting it.
The click-through rates used
| Position | Click-through rate | With an AI Overview |
|---|---|---|
| #1 | 27.6% | 17.9% |
| #2 | 15.8% | 10.3% |
| #3 | 11.0% | 7.2% |
| #4 | 8.4% | 5.5% |
| #5 | 6.3% | 4.1% |
The extension models positions 1 to 10. The first five are shown here.
Where each number comes from
- Monthly search volume — Google Ads volume, via seodata.dev
- An advertising metric, not an organic one. Google buckets and rounds these figures, and they are a twelve-month average rather than a current month.
- Click-through rate by position — Backlinko (2023, ~4M searches) and Sistrix (2020, ~80M keywords), blended
- The two studies agree closely at the top of page one and diverge further down, where both have thinner samples. Past position 10 the extension reports no estimate at all rather than extrapolating.
- The AI Overview reduction — Ahrefs (March 2025) measured position-one click-through down 34.5% on queries showing an AI Overview
- Other measurements differ: Amsive found about −15.6% on average, Pew found the any-click rate roughly halved. One conservative multiplier is applied and disclosed, because a ten-position AI Overview curve would be more precise than any published evidence supports.
Only the page you are looking at knows about the AI Overview
Every other tool that estimates search traffic computes its numbers on a server, from a keyword database. That is fine for most purposes and hopeless for one: Google personalises and tests where AI Overviews appear, so the results page a data centre was shown is not reliably the results page you were shown.
An extension reads the rendered page. If your search had an AI Overview on it, the estimates account for that. If it did not, they do not. That is the whole reason this is a browser extension and not another page on this site.
It is worth being clear about the size of the effect, because the published measurements disagree: Ahrefs measured position-one click-through down about 35% on AI Overview queries, Amsive found closer to 15% across their set, and Pew found the overall any-click rate roughly halved. The extension applies one conservative figure and tells you it has done so.
What it deliberately does not do
- It does not measure anyone's traffic. Nobody outside Google can measure another site's clicks. This is a model built from public figures, and it is labelled as one everywhere it appears.
- It does not estimate site-wide traffic. Only what a result earns from the one query on screen. A site-wide figure needs a measurement panel or a licensed index, and any tool offering you one cheaply is guessing.
- It gives no estimate past position 10. The published click-through curves are too thin down there to publish a number from.
- Search volume is an advertising metric. Google Ads volumes are bucketed, rounded and averaged over twelve months, so a seasonal term reads flat and a small term reads coarse.
- It will break when Google changes its markup. When it does, the badges stop appearing and it says so rather than showing something wrong.
What leaves your browser
The search query you typed, sent to seodata.dev to look up its monthly search volume. That is the only thing.
Not the results, not the pages you go on to visit, not your browsing history, and nothing identifying you. Volumes are cached in your own browser for a week, so a query you repeat costs no request at all. There is no account, no login and no tracking in the extension. Ourprivacy policy describes this in full.
Common questions
No, and the extension will never claim it is. Nobody outside Google can measure another site’s clicks. Every badge is a model: the monthly search volume for the query you typed, multiplied by a published click-through rate for that result’s position. The badge carries the word "modelled" and the tooltip names the study behind each half of the sum.
Because per-query is the question you are actually asking while looking at a results page, and because site-wide traffic cannot be estimated honestly at this price. A site-wide figure needs either a measurement panel of real browsing data or a licensed keyword index, both of which cost thousands a month. Per-query needs one number — the volume of the search in front of you — and tells you what the position is worth on this term.
When Google shows an AI Overview, organic results move down the page and take measurably fewer clicks. The extension detects the AI Overview in the page you are actually looking at and reduces every estimate accordingly, turning the badges amber so the lower number has a visible reason. This is the one thing a browser extension can do that a server-side tool cannot: Google personalises and tests where AI Overviews appear, so an API asked the same query from a data centre may have been shown one when you were not.
No. It works with no account and no email. The search volume comes from seodata.dev, which allows a number of anonymous lookups per day at no cost — and because one lookup covers a whole results page rather than one per result, that allowance goes a long way. If you search heavily enough to exhaust it, you can add your own seodata.dev key in the extension’s settings.
The search query you typed is sent to seodata.dev to look up its monthly search volume. Nothing else leaves your browser: not the results, not the pages you visit, not your browsing history, and nothing that identifies you. Volumes are cached locally for a week so the same query is not looked up twice. See our privacy policy for the full description.
The published click-through studies get unreliable past the first page — the samples thin out and the measurements disagree. Rather than extrapolate the curve into territory nobody has measured properly, the extension says it has no estimate. A small invented number would look more useful and be worth less.
Those show site-wide metrics from their own licensed indexes and panels, and they are better at that than this will ever be. This answers a narrower question — what is this result worth on this specific search — and it reads the rendered page, so it knows whether your search showed an AI Overview. They are complementary rather than competing, and this one is free with no account.
Badges stop appearing, and the extension logs a warning saying its selectors no longer match rather than failing silently. Google changes its results markup regularly, so this is a question of when. The parser deliberately anchors on page structure rather than Google’s class names, which are the part that changes most often.

Want to know what those positions are worth to you?
A badge tells you what a result earns on one query. What it cannot tell you is whether those searches are the ones your buyers make, or what it would take to hold position three on them. If you want that read, tell us about the business.
