SEO vs PPC Statistics: 2026 Data on CTR, Cost, Conversion and ROI

SEO vs PPC statistics at a glance

How we researched these SEO vs PPC statistics

This report prioritizes original or first-party datasets over statistic roundups. We reviewed the publisher’s sample, date, geography and metric definition before including a figure. Where a source reports a median, we call it a median. Where a finding is observational, we do not present it as proof of causation.

The core sources are LocaliQ’s 2026 analysis of 13,474 US Google Ads search campaigns; SparkToro and Similarweb’s US clickstream analysis; two Ahrefs studies covering AI Overviews; Statcounter’s US search engine usage data; and First Page Sage’s proprietary client datasets. HubSpot’s global marketer survey is included as evidence of budget intentions and perceptions—not as proof of channel ROI.

We excluded popular claims when the original source could not be verified, when a statistic was repeatedly cited without a clear sample, or when an old figure was presented as a current benchmark. We also avoided building a false head-to-head result by comparing an SEO conversion rate from one provider with a PPC conversion rate from another. Different definitions of a conversion can make that comparison meaningless.

Important: these figures describe selected datasets. They are not promises, and they are not a substitute for a forecast based on your margins, market, site, sales process and historical account data.

Definitions that prevent bad SEO vs PPC comparisons

SEO

Search engine optimization: technical, content, authority and user-experience work intended to improve unpaid search visibility. Organic clicks do not carry a platform fee per click, but the work that earns them is not free.

PPC

Pay-per-click advertising. In this report, PPC mainly means paid search ads, not paid social or display advertising. Advertisers typically pay when someone clicks an ad.

CTR

Click-through rate: clicks divided by impressions. Organic CTR and ad CTR should be kept separate because their layouts, positions and denominator definitions differ.

CPC

Cost per click: media spend divided by paid clicks.

Conversion rate

Conversions divided by visits or clicks. A form submission, phone call, booked meeting and completed purchase are very different outcomes, even if each publisher calls them a conversion.

CPL and CAC

Cost per lead measures the cost of generating a lead. Customer acquisition cost includes the cost required to win an actual customer. A low CPL can still produce a poor CAC if lead quality is weak.

ROAS and ROI

Return on ad spend compares attributable revenue with ad spend. Return on investment should account for the wider cost of the program and, ideally, gross profit rather than revenue alone.

Search market statistics: Google still dominates US search

Google accounted for 86.1% of US search engine usage in August 2026, according to Statcounter’s search engine market-share tracker. Bing held 8.92%, Yahoo 2.74% and DuckDuckGo 1.7%. Statcounter measures usage observed through its network, so its percentages should be treated as an indicator of market activity rather than a census of every US query.

The implication is straightforward: Google remains the main planning environment for both SEO and paid search in the United States. But a Google-first strategy should not become a Google-only measurement system. Search discovery now extends into Bing, AI answer engines, marketplaces, maps, social platforms and vertical directories. The correct scope depends on where customers actually research a purchase.

HubSpot’s 2026 State of Marketing, based on more than 1,500 global B2B and B2C marketers, found that 35.4% planned to increase investment in websites, blogs and SEO. Another 40.6% identified updating SEO for changes in search as a top trend. Those responses show continued marketer interest, but the survey combines websites, blogs and SEO into one category and measures plans rather than realized returns.

PPC statistics for 2026

The strongest current US paid-search benchmark we found is LocaliQ’s 2026 Google Ads benchmark report, published by WordStream. It covers 13,474 US search advertising campaigns that ran from April 1, 2025 through March 31, 2026 across 23 industries. Each industry subcategory included at least 52 unique campaigns. Although the report uses the familiar word “average,” its methodology says the presented figures are technically medians.

2026 Google Ads search benchmarks

Paid-search costs vary more by industry than the overall median suggests

Legal and high-consideration local services face far different auctions from restaurants, travel or entertainment. In LocaliQ’s 2026 data, attorneys and legal services had a median CPC of $9.87, about 6.1 times the $1.63 median for arts and entertainment. The legal median cost per lead was $131.63, about 4.9 times the arts and entertainment figure of $26.84.

Ten-year PPC trend: clicks cost more, but reported conversion improved

LocaliQ also compared its 2026 medians with WordStream’s 2016 benchmarks. Median CPC increased from $2.32 to $5.42, while conversion rate increased from 2.70% to 8.18%. Median cost per lead moved from $59.18 to $66.69.

Our calculations put those changes at 133.6% for CPC, 203.0% for conversion rate and 12.7% for cost per lead. That does not mean every advertiser became three times better at converting. Conversion tracking, campaign automation, lead definitions, keyword matching and the underlying campaign sample all changed over a decade. The comparison is useful as market context, not as a controlled experiment.

The more recent direction is encouraging: conversion rate improved in 87% of the industries in the 2026 report, and overall cost per lead fell for the first time in five years. Still, the relevant benchmark for a business is its own qualified-lead and customer economics.

SEO statistics for 2026

SEO still offers access to high-intent demand without a media charge for each visit. What changed is the number of searches that produce an external click. Featured snippets, local results, shopping modules, knowledge panels and AI answers can resolve a query directly on the search page.

68.01% of US Google searches ended without a click

SparkToro and Similarweb’s 2026 clickstream analysis found that 68.01% of US Google searches on desktop and mobile browsers ended without a click during January through April 2026. The comparable reported figure for 2024 was 60.45%.

That is an increase of 7.56 percentage points, or roughly 12.5% relative growth in the zero-click share. The study also reported that the share of searches producing any kind of click declined 22.9% between 2024 and 2026.

This does not make SEO irrelevant. It changes the job. Search visibility can introduce a brand, answer a question and influence a later branded search even when the first impression does not generate a visit. But if the business case depends on sessions, the forecast should use post-SERP click behavior rather than total keyword search volume.

The study has material limitations. Its 2024 and 2026 panels were not identical, the Google mobile search app was excluded, and mobile paid-click share was estimated using a ratio rather than directly measured. SparkToro also reported that Google’s AI Mode represented only 0.34% of searches in this early-2026 sample, so zero-click behavior cannot be attributed to AI alone.

For a deeper treatment of this shift, see Prime Digital’s analysis of AI’s impact on SEO statistics.

AI Overviews appeared on 20.5% of the desktop SERPs studied

Ahrefs analyzed 146,122,391 desktop search result pages from September 2025 and found an AI Overview on 20.5% of them. The feature was much more common on question queries, at 57.9%, and on queries of seven or more words, at 46.4%. It appeared on only 7.9% of local searches. Almost all triggering keywords—99.9%—were classified as informational.

The Ahrefs AI Overview trigger study was large, but it covered desktop SERPs during one period and was not identified as a US-only sample. Use it to understand query patterns, not to claim that exactly one in five searches made by a specific US audience will show an AI Overview.

An AI Overview correlated with 58% lower position-one CTR

In a separate study, Ahrefs examined 300,000 keywords: 150,000 with an AI Overview and 150,000 informational queries without one. It used aggregated Google Search Console desktop data and compared December 2023 with December 2025.

The study found a 58% lower average CTR for the top-ranking page when an AI Overview was present. In December 2025, the observed position-one CTR was about 1.6% for AI Overview queries and 3.9% for the informational no-AI-Overview sample. Ahrefs estimated that the AI Overview group would otherwise have reached roughly 3.73%.

The estimated effect became smaller lower on the page: 50.8% at position two, 46.4% at position three and 19.4% at position ten. This was an observational study, so “correlated with” is the accurate phrase. It does not establish that an AI Overview alone caused every lost click.

Ranking does not guarantee traffic

An older but still useful warning comes from Ahrefs’ analysis of approximately 14 billion pages in its Content Explorer index. The company estimated that 96.55% received no organic traffic from Google, while another 1.94% received only one to ten visits per month. The study was published in 2023, traffic was estimated rather than measured for every page, and the keyword database was incomplete. It should not be quoted as a live 2026 market share.

Its practical message holds: publishing a page is not the same as creating demand or earning distribution. A page needs a reachable query set, search intent fit, sufficient authority, crawlability, useful information and a reason to be selected over existing results.

Why old organic CTR curves are not 2026 forecasts

A widely cited SISTRIX study of 80 million keywords found that the first organic result averaged a 28.5% mobile CTR, followed by 15.7% for position two, 11% for position three and 2.5% for position ten. More importantly, position-one CTR ranged from 13.7% to 46.9% depending on the result-page layout. A shopping-heavy result produced a 13.7% figure, while a layout with Google Ads ahead of organic results produced 18.8%.

That SISTRIX CTR study was published in 2020, before broad AI Overview deployment. It remains good evidence that SERP composition matters, but its headline position-one average should not be dropped into a 2026 revenue forecast.

SEO vs PPC conversion rate statistics

The internet contains apparently precise claims that SEO converts at 14.6%, paid search at 3.17% or PPC at 10%. Those numbers often come from different years, businesses, traffic definitions and conversion events. Putting them in adjacent cells does not make the comparison valid.

The cleanest direct comparison we found comes from First Page Sage’s SEO vs PPC conversion analysis. The agency used the same internal definitions across 124 clients between August 2022 and July 2024. It reported an overall SEO conversion rate of 2.4% and PPC conversion rate of 1.3%. Within that dataset, SEO’s conversion rate was about 1.85 times PPC’s.

Why is First Page Sage’s 1.3% PPC rate so different from LocaliQ’s 8.18%? The studies measure different campaign populations under different definitions and periods. LocaliQ analyzed thousands of US search advertising campaigns and reported its platform-level median conversion rate. First Page Sage analyzed conversions in its own smaller client portfolio to make a channel comparison. Neither number invalidates the other; they answer different questions.

For planning, define a qualified conversion first. Then calculate SEO and PPC rates from the same analytics setup, date range, market and attribution rules. If a paid call is counted after 15 seconds but an organic call only after 60 seconds, the comparison is already biased.

SEO vs PPC cost and ROI statistics

PPC exposes its marginal cost clearly: each additional click participates in an auction, and traffic generally falls quickly when spend stops. SEO has no auction fee for an organic click, but it requires technical work, content, subject-matter input, digital PR, tools and maintenance. Rankings can also decline after an algorithm change, a site migration or stronger competition.

That difference makes simplistic ROI claims unreliable. PPC cost is visible in the ad account. SEO cost is often scattered across salaries, agencies, developers and content teams. A comparison that includes all PPC media spend but only an SEO software subscription is not fair.

One proprietary SEO ROI dataset

First Page Sage’s SEO ROI report summarizes campaigns from the first quarter of 2021 through the third quarter of 2025. It reports three-year averages for high-investment thought-leadership programs, often costing around $120,000 per year plus some client-side staff costs.

The reported industry results include 8.75 ROAS and 702% ROI for B2B SaaS, 3.65 ROAS and 317% ROI for ecommerce, 11.10 ROAS and 1,031% ROI for financial services, and 6.15 ROAS and 526% ROI for legal services. Reported break-even time ranged from seven months for B2B SaaS to 14 months for legal services among those examples.

The same provider reported very different outcomes by SEO service type: 1.35 ROAS and 117% ROI for technical SEO, 1.05 ROAS and 16% ROI for basic content marketing, and 9.10 ROAS and 748% ROI for thought-leadership SEO. This is vendor-proprietary data from a selected client portfolio, not an independent market benchmark. It is most useful for showing that “SEO” is not one uniform intervention.

What can be concluded responsibly

• PPC produces data faster. A campaign can begin generating impressions, clicks and conversion signals as soon as it is approved and funded.
• SEO usually needs a longer evaluation window. Indexing, ranking, authority and content coverage develop over time. A short test can understate its eventual contribution.
• PPC has an explicit variable media cost. In the 2026 LocaliQ sample, one click cost a median $5.42 before management and creative expenses.
• SEO has a front-loaded and ongoing production cost. The organic click has no platform charge, but the system that earns it must be built and maintained.
• Neither channel has a universal ROI. Margin, close rate, repeat purchases, sales cycle, branded demand and attribution choices can reverse a headline comparison.

Prime Digital calculations from the source data

The following figures are our arithmetic based on the cited publisher data. They are not additional survey findings.

One calculation we deliberately do not make is a synthetic “typical campaign” by multiplying LocaliQ’s separate median CPC, conversion rate and CPL. At $5.42 per click, 1,000 clicks would cost $5,420. Applying the separate 8.18% median conversion rate would imply 81.8 conversions and $66.26 per conversion, not the reported $66.69 median CPL. The small difference is expected because each metric is a separate median across campaigns. Medians are not components of one composite account.

When to choose SEO, PPC or both

A useful combined strategy

1. Use PPC to learn. Test high-intent terms, offers, objections and landing pages. Import qualified leads and closed revenue where possible, not just form submissions.
2. Use the evidence to prioritize SEO. Build pages around topics that show qualified demand, while also covering useful informational questions that ads cannot address efficiently.
3. Defend branded searches. Measure whether competitors, resellers or aggregators appear on brand queries before deciding whether branded PPC is incremental.
4. Allocate by marginal return. Increase investment where the next dollar is expected to produce the most gross profit, rather than applying a permanent percentage split.
5. Measure search influence. Track assisted conversions, branded-search lift and qualified pipeline alongside last-click sessions as zero-click and AI-result exposure grows.

Build an SEO vs PPC budget model from unit economics

PPC break-even model

Start with the maximum amount the business can pay for a lead:

Maximum break-even CPL = average gross profit per new customer × lead-to-customer rate.

If a new customer produces $2,000 in gross profit and 10% of qualified leads become customers, the theoretical break-even CPL is $200. A safety margin is still needed for overhead, refunds, attribution error and growth targets. If expected CPC is $8 and the landing page converts 5% of clicks into qualified leads, expected media CPL is $160:

$8 CPC ÷ 5% qualified-lead conversion rate = $160 media CPL.

Add management, landing-page, call-tracking and creative costs before comparing that result with the $200 ceiling. Use the account’s qualified conversion rate—not a broad internet benchmark—once enough data exists.

SEO break-even model

SEO needs a cohort view because cost and return occur at different times:

SEO CAC = total attributable SEO cost over the evaluation period ÷ new customers attributable to organic search.

Include strategy, technical implementation, content, design, subject-matter review, digital PR, tools and internal staff time. Track results over a period long enough for the work to be indexed and compete. Separate branded and non-branded organic performance so pre-existing brand demand does not receive all the credit.

For both channels, use gross profit or contribution margin when possible. Revenue-based ROAS can look healthy while the campaign loses money after fulfillment and sales costs.

How to measure SEO and PPC fairly

A fair comparison requires the same business outcome, measurement period and attribution logic. Use this checklist before moving budget:

• Normalize the conversion. Count the same qualified action in both channels. Do not compare paid form fills with organic closed customers.
• Import offline outcomes. Connect CRM stages, revenue and lost-lead reasons to analytics and ad platforms where privacy and consent permit.
• Separate brand from non-brand. Branded search often converts at a higher rate because demand already exists.
• Use comparable markets. Geography, device, season and product availability affect both auction prices and organic behavior.
• Include total cost. Add media and management to PPC; add staff, tools, production and implementation to SEO.
• Choose a suitable time horizon. Weekly PPC optimization and a 12-month SEO investment should not be judged through the same short snapshot.
• Check incrementality. Ask what would have happened without the channel. Brand ads and navigational organic visits may capture demand created elsewhere.
• Report uncertainty. Small samples can swing sharply. Use ranges and confidence levels instead of false precision.

A technical foundation still matters. Broken indexing, duplicate pages, slow templates or bad tracking can make both the SEO program and its measurement unreliable. A free website audit can help identify where to investigate first, while our SEO case study shows how Prime Digital approaches performance evidence.

SEO vs PPC statistics: frequently asked questions

Is SEO better than PPC in 2026?

SEO is better for building durable non-paid visibility when a business can invest over a longer period. PPC is better for immediate, controllable exposure and rapid testing. Most established businesses benefit from using both, then allocating budget according to qualified customer acquisition cost and incremental profit.

Does SEO have a higher conversion rate than PPC?

Not universally. First Page Sage reported 2.4% for SEO and 1.3% for PPC in its 124-client, B2B-heavy sample, but higher education was an exception in the same dataset. LocaliQ reported an 8.18% median Google Ads conversion rate in a different 2026 campaign sample. The figures cannot be combined because their populations and definitions differ.

What is the average PPC conversion rate in 2026?

LocaliQ reported an 8.18% median conversion rate across 13,474 US Google Ads search campaigns running between April 2025 and March 2026. Treat it as a benchmark, not a forecast. Industry, query intent, landing page, offer and conversion definition can move the result substantially.

What is the average Google Ads cost per click in 2026?

The median CPC was $5.42 in LocaliQ’s 2026 US search advertising benchmark. Selected industry medians ranged from $1.63 for arts and entertainment to $9.87 for attorneys and legal services.

How many Google searches result in no click?

SparkToro and Similarweb reported that 68.01% of US Google searches on desktop and mobile browsers ended without a click from January through April 2026. The study excluded the Google mobile search app and used an estimate for mobile paid-click share.

Do AI Overviews reduce organic clicks?

Ahrefs found that an AI Overview correlated with a 58% lower average CTR for the top-ranking page in its 300,000-keyword study. This is strong directional evidence, but it is an observational result rather than proof that the AI Overview caused every difference.

Is SEO traffic free?

No. Organic clicks have no search-engine fee per click, but earning them requires investment in strategy, technical work, content, expertise, authority, tools and maintenance. SEO should be evaluated on total cost, not media cost alone.

How long does SEO take compared with PPC?

PPC can begin producing traffic after campaign approval and launch. SEO timing varies with the site’s condition, competition, content gap and authority. The First Page Sage proprietary ROI dataset reported break-even periods of seven to 14 months in selected industries, but that is not a universal timeline.

What is a good SEO vs PPC budget split?

There is no standard split. Fund enough PPC to test and capture high-intent demand, while giving SEO enough sustained investment to build useful coverage. Reallocate according to marginal gross profit, sales capacity and the confidence of the measurement—not a fixed industry percentage.
