What Is Semrush Traffic Cost? (And Why It Isn't What Semrush Costs You)

The short answer: Traffic Cost is Semrush's estimate of what a website's organic traffic would cost to buy through Google Ads instead. It is not the price of a Semrush subscription, and it is not revenue the site earns. It's a replacement-cost estimate: volume × CPC, summed across every keyword the domain ranks for.

That first distinction matters more than it sounds. A large share of the people searching "Semrush traffic cost" are actually asking what Semrush charges — two completely different questions that happen to share a phrase. If that's you, the subscription figures are in our Semrush pricing breakdown. If you want to understand the metric inside the tool, keep reading.

What is Traffic Cost in Semrush?

Traffic Cost estimates how much a domain would have to spend on Google Ads to acquire the same traffic it currently gets from organic search.

You'll find it in Semrush's Organic Research overview, sitting beside two related numbers: the count of keywords the domain ranks for in Google's top 100, and the estimated monthly organic traffic those rankings produce. Traffic Cost is the third figure — the dollar value attached to that traffic at paid-search rates.

Ahrefs publishes the same concept under a different name, "Traffic value". The idea is identical; the numbers won't match, because each tool uses its own keyword database, its own click-through-rate model and its own CPC data.

How is Semrush Traffic Cost calculated?

It's a sum of per-keyword estimates: for every keyword the domain ranks for, Semrush multiplies the estimated traffic that keyword sends by that keyword's cost per click, then adds them all together.

Estimated traffic per keyword is itself a calculation — monthly search volume multiplied by an assumed click-through rate for the position the domain holds. So the metric is an estimate built on top of two other estimates.

Worked through with illustrative numbers, using a 10% CTR assumption for position 3:

Same traffic. Same position. Same search volume. A 20× gap in Traffic Cost, driven entirely by what advertisers are willing to bid.

This is the single most useful thing to understand about the metric: Traffic Cost measures commercial intent at least as much as it measures traffic.

Why does Traffic Cost get confused with Semrush's price?

Because "traffic cost" reads like a billing term, and Semrush is a paid tool. The phrase suggests "what my traffic costs me" — as in, what I'm being charged.

It isn't. Nobody pays the Traffic Cost figure to anyone. It's a hypothetical: what this traffic would cost if bought through ads. A domain showing $88,000/mo Traffic Cost is not spending $88,000, and is not earning it either.

If your actual question is what the tool charges, Semrush's entry SEO plan is $139.95/mo ($117.33/mo billed annually), with three higher tiers above it. The full breakdown — including the seat costs that catch people out — is in our Semrush pricing guide, and the wider feature picture is in our Semrush review.

What is Traffic Cost actually useful for?

It's a competitive-priority signal, not a valuation.

Three jobs it genuinely does well:

• Ranking competitors by commercial threat. Two competitors with similar traffic but very different Traffic Cost are playing different games. The high-Traffic-Cost one owns the keywords buyers search before spending money. That's the one worth studying.
• Finding which of your own pages carry commercial weight. Sorting your keywords by traffic cost surfaces the ones with buying intent, which is usually a better content-priority list than sorting by volume.
• Making an SEO budget legible to someone who thinks in ad spend. "This traffic would cost $12,000/mo through Ads" is a sentence a finance team understands. It's a rhetorical framing, not an accounting fact — but it's a fair one.

Where does the Traffic Cost metric mislead?

In four specific ways, all worth knowing before you quote the number to anyone.

It isn't revenue. This is the most common misreading after the pricing confusion. Traffic Cost tells you what the traffic would cost to buy, not what it earns. A site with $50,000/mo Traffic Cost might monetise at a fraction of that — or not at all. Our own site is a live example of the gap between traffic metrics and outcomes: we currently draw over 4,000 search impressions a week and convert them to almost nothing, because impressions at position 70 don't become visits.

The CPC data is estimated, not observed. Semrush doesn't have access to Google's actual auction prices. It models them. For high-volume commercial terms the estimates are reasonable; for low-volume or niche terms they get thin, and some keywords carry no reliable CPC at all.

The CTR assumption hides a lot. Estimated traffic depends on an assumed click-through rate for each position. Real CTR varies enormously with SERP features — an AI Overview, a featured snippet or a pack of ads above your result can cut actual clicks far below the model's assumption, while the metric carries on as if position 3 always delivers position-3 traffic.

Cross-niche comparisons are meaningless. As the worked example above shows, a legal or SaaS site will post a Traffic Cost many times that of a recipe site with identical traffic. Comparing the two tells you about their advertisers, not their SEO.

Do you need Semrush to work out what traffic is worth?

Not for the underlying calculation. You need two inputs — search volume and CPC per keyword — and several cheaper tools provide both.

Mangools gives you exact search volume, CPC and PPC data per keyword in KWFinder at $49/mo month-to-month, or $29.90/mo billed annually. At monthly list prices that's roughly a third of Semrush's $139.95 — the comparison is monthly-to-monthly on both sides.

The honest trade-off: Mangools hands you the inputs, not a packaged domain-level Traffic Cost figure. If you want to see one number for a competitor's whole domain without doing arithmetic, that's a Semrush (or Ahrefs) feature and Mangools won't replace it. If you're working keyword by keyword — which is what most freelancers actually do — you already have everything the formula needs.

The verdict on Traffic Cost

Traffic Cost is a useful comparative signal wearing a misleading name. It tells you how commercially valuable a set of rankings is in advertising terms, which makes it good for sizing up competitors and prioritising your own pages. It tells you nothing about revenue, and comparing it across different niches is close to meaningless.

Two rules keep you out of trouble with it. Never quote it as what traffic is worth — quote it as what traffic would cost to replace. And never compare it between industries, only between direct competitors chasing the same keywords.
