SEO vs PPC statistics at a glance

Which is cheaper, SEO or PPC?

PPC is cheaper in year one and SEO is cheaper by year two: a 12-month SEO retainer works out at $265 per lead after 12 months, $78 after 24 and $46 after 36, while paid search sits at a flat $100 forever.

How long does SEO take to beat PPC?

SEO takes about 19 months to overtake the same budget spent on Google Ads, which is roughly double the 9-month median break-even that agencies quote for SEO on its own.

Which converts better, SEO or PPC?

Paid search converts slightly better than organic search, 5.4% against 4.9% in the only study that measures both with the same method, and the gap is far too small to explain the price difference between the two channels.

How much do brand and non-brand keywords change the maths?

Brand keywords make PPC look far cheaper than it is: B2B SaaS accounts pay $34 for a brand search lead and $207 for a non-brand one, a 6.1x gap inside the same channel.

The two incrementality studies point in opposite directions and both are more than a decade old. Google's 89% figure comes from advertisers who paused campaigns and measured clicks. eBay's comes from an economist switching off entire regions and measuring sales. Clicks and sales are different outcomes, which is most of the disagreement, and eBay is a brand whose customers were always going to find it.

How much of a marketing budget goes to SEO vs PPC?

Paid search takes 16% of the digital marketing budget in 2026 while receiving roughly 1% of all US Google clicks, a 16-to-1 gap that sets budget share against click share, so it is a sense check on how the channel is priced rather than an efficiency ratio you can spend.

Is paid search taking click share back from organic?

Yes, in commercial categories: paid click share across four US product categories rose from 11.8% to 25.5% between January 2025 and January 2026, while classic organic lost between 11 and 23 percentage points in every one of them.

How much PPC spend never reaches a human?

8.51% of paid ad clicks are invalid traffic and 29.5% of internet users run an ad blocker, which pushes the real cost of a search lead from $66.69 to $72.15.

Are AI Overviews hurting SEO or PPC more?

AI Overviews are hurting organic harder in relative terms and both channels in absolute terms: the top organic result loses 58% of its click-through rate when an overview appears, and Seer Interactive measured a 61% organic and 68% paid CTR decline on overview queries.

When should you buy clicks instead of earning them?

Buy clicks when your payback window is shorter than 19 months, when the query is commercial, or when the search volume is too small for content to compound; earn them when you plan to still exist in three years and the query is informational.

Four situations where PPC is the right answer, each with the number behind it:

1. You need results this quarter. SEO returns nothing for 3 to 6 months (Ahrefs, 2024) and only overtakes an equal ad budget at month 19 (computed). If your runway is shorter than that, the comparison is over.
2. The category has re-monetised. Text ads took 16% of clicks on headphones and jeans queries in January 2026, up from 3% and 7% (Aleyda Solis / Similarweb, 2026). Ranking first there wins you less of the page than it did a year ago.
3. You are testing demand. A non-brand paid click costs $13.75 in B2B SaaS (PipeRocket, 2026), a cheap way to find out whether a keyword converts before you spend six months writing for it.
4. The query is transactional. Paid search converts at 5.4% against organic's 4.9% (Ruler Analytics, 2026), and that edge is worth most where the intent to buy is highest.

Three where SEO wins outright: informational queries, brand terms you already own (NBER, 2014), and any programme with a horizon past two years, where the cost per lead falls to $46 while PPC stays at $100 (computed).

How we calculated the original numbers

Five figures on this page are computed here. The arithmetic is below, so you can check it or swap the inputs.

1. Month 19, the SEO break-even against equal PPC spend. Give each channel $2,917 a month, the average SEO retainer (Ahrefs, 2024). PPC buys $2,917 / $5.42 = 538 clicks a month from month one (WordStream / LocaliQ, 2026). SEO returns zero for three months (Ahrefs, 2024), then ramps in equal steps to the same 538 clicks by month 12: 2,691 cumulative clicks against PPC's 6,458. Both budgets stop at month 12, paid traffic goes to zero and organic holds at 538 a month. The 3,767-click gap closes in 7.0 months, so break-even is month 19.
2. $265, $78 and $46 per lead. Apply Ruler Analytics' same-study conversion rates, 4.9% organic and 5.4% paid (Ruler Analytics, 2026), to the click counts above. Twelve months of SEO spend is $35,004 and yields 132 leads, or $265 each; by month 24 that same $35,004 has produced 448 leads, or $78; by month 36, 765 leads, or $46. PPC never moves: $2,917 divided by 538 clicks at 5.4% is $100 in every month you fund it. On this denominator the crossover arrives later than month 19: at month 20 an SEO lead still costs $102 against paid's $100, and it only goes clear in month 21.
3. 16x, budget share against click share. Paid search takes 16% of the digital marketing budget (Gartner 2026 CMO Spend Survey) and about 1% of all US Google clicks (SparkToro / Datos, 2024). The denominators differ, so this is a sense check, not a ratio you can spend.
4. $72.15, the real cost of a paid lead. Lunio measured 7.57% invalid traffic on Google ads (Lunio, 2026). Dividing the $5.42 CPC and the $66.69 cost per lead by 0.9243 gives $5.86 per valid click and $72.15 per valid lead.
5. 11.8% to 25.5%, paid click share across four categories. Average the text ad plus shopping ad shares in Aleyda Solis' table for headphones, jeans, greeting cards and online games: 16, 18, 10 and 3 in January 2025, then 36, 34, 19 and 13 in January 2026. The means are 11.75% and 25.5%, a 2.2x rise in twelve months.

Two assumptions carry most of the weight and both favour SEO: that a retainer reaches paid-equivalent traffic volume by month 12, and that organic traffic then holds flat for two more years with no spend at all. The second one is getting less true every quarter, which is what the AI Overview section is about.

What the 2026 numbers actually say

This is a cash-flow question, not a channel question. PPC is a fixed price for a fixed result: $100 a lead, forever, starting Tuesday. SEO is capital expenditure with a 19-month payback and a residual value nobody guarantees. Framed that way, most of the argument disappears. A company with 18 months of runway should not be buying an asset that pays off in 19.

Brand keywords are where the honest comparison goes to die. A 6.1x cost per lead gap between brand and non-brand search inside the same accounts means every blended PPC benchmark, the $66.69 everyone quotes included, is part toll booth and part real demand capture. Split them before you decide anything.

The residual value of organic traffic is the number to watch. Every SEO business case, mine included, assumes the traffic you earn keeps arriving after you stop paying. A 58% CTR hit when an AI Overview appears, and a 22.9% fall in Google clicks of any kind in two years, are both attacks on that assumption. If organic decays faster from here, month 19 becomes month 25 and the case for buying clicks gets stronger without a single CPC moving.

FAQ

Is SEO cheaper than PPC?

Over 24 months, yes. A 12-month SEO retainer at $2,917 a month works out at about $78 per lead by month 24 and $46 by month 36, against a flat $100 for paid search, using Ruler Analytics' 2026 rates of 4.9% organic and 5.4% paid. In year one PPC is far cheaper, $100 a lead against SEO's $265.

How long does SEO take to beat PPC on cost?

Nineteen months, computed from Ahrefs' $2,917 average retainer (2024) and WordStream/LocaliQ's $5.42 average CPC (2026). That is roughly double the 9-month median break-even First Page Sage reports for SEO measured against itself rather than against an alternative use of the money.

Which converts better, SEO or PPC traffic?

Paid search, by half a percentage point. Ruler Analytics measured 5.4% for paid search and 4.9% for organic search across 110 million sessions in 2026. Conversion rates quoted from inside Google Ads, such as WordStream's 8.18%, use a different denominator and are not comparable.

How much of a marketing budget goes to paid search?

16% of the digital marketing budget in 2026, up from 14.8%, according to Gartner's 2026 CMO Spend Survey of 401 CMOs. SEO takes 9.4% of the owned and earned digital media budget, and paid media overall reached 31.4% of total marketing expenses.

Do AI Overviews hurt SEO or PPC more?

Both, and organic more in relative terms. Ahrefs found the top organic result loses 58% of its CTR when an AI Overview is present (February 2026, 300,000 keywords). Seer Interactive measured a 61% organic and 68% paid CTR decline on overview queries between June 2024 and September 2025.

Should you bid on your own brand name?

The evidence says usually not. eBay's field experiment across 68 US marketing areas found no measurable short-term benefit from brand-keyword ads (Blake, Nosko and Tadelis, 2014), and B2B SaaS brand leads cost $34 against $207 for non-brand (PipeRocket, 2026), which flatters any blended account average. Bid to keep a competitor off your name, not to buy traffic you already have.

Methodology. Numbers were collected in September 2026 and checked against the original publisher's page, not against other statistics roundups. Vendor claims without a stated sample or method were excluded; vendor benchmarks that are kept, including First Page Sage, PipeRocket Digital and Lunio, are labelled with their sample and their commercial interest. Six sources predate September 2024 and are marked dated in the tables: the two Ahrefs surveys, the SparkToro / Datos clickstream study, and the three 2011 to 2014 incrementality papers, which are kept because no newer equivalent exists. Where conversion rates are compared, both sides come from the same study to keep the denominator consistent. Last updated 8 September 2026.
