B2B SEO statistics for 2026, in plain English.
B2B means business to business: companies that sell to other companies, like agencies and software firms. This page covers how business buyers research, how they use AI, what SEO costs per lead and what works. Every figure has a date, and all sources are listed at the end.
The 6 numbers that matter most.
The short version. Each card explains what the number means if you sell to other businesses.
Deals won by a company that was already on the buyer’s first list of options.
Share of the buying process done before the buyer contacts any seller. It was 69% a year before.
Software buyers who now start research with an AI chatbot more often than Google. A year earlier it was 29%.
Business buyers who would rather buy without talking to a sales rep. It was 61% before.
Cost per lead for B2B software firms: organic search against paid ads.
Marketers who say AI made them faster, against those who say it made their content work better.
How business buyers decide.
6sense asked about 3,996 buyers. Their typical deal was worth $200,000 to $400,000.
How B2B buying works in 2025
Share of buyers or deals.
This changes what SEO is for. Most deals go to a company that was on the list before the buyer spoke to anyone. So the job of search is to get your name onto that first list of 3 or 4 companies. Buyers look at 5.1 companies on average and spend about 2 months with each.
Buying got a little faster this year. The average buying cycle fell from 11.3 months to 10.1 months. For context, a 2012 study by CEB and Google put the share of research done before contact at 57%. It went up to 69% and is now 61%.
Who is involved in a business purchase.
| Finding | Figure | Source |
|---|---|---|
| People inside the company plus outside advisers in a typical purchase | 13 + 9 | Forrester (2026) |
| Purchases where top bosses (the C-suite) decide | 68% | Forrester (2026) |
| Purchases where the buying team (procurement) decides | 53% | Forrester (2026) |
| Buying group size for purchases that include AI | about double | Forrester (2026) |
| Buyers who prefer to buy without a sales rep | 67% (was 61%) | Gartner (646 buyers, 2026) |
| Buyers who used AI tools in a recent purchase | 45% | Gartner (2026) |
You may see an older figure of “6 to 10 decision makers”. That comes from a 2017 Gartner survey and counts only people with a formal vote. Forrester’s 22 counts everyone who has a say. Both are useful. They just count different people.
How business buyers use AI.
G2 surveyed 1,076 business decision makers in North America, Europe and Asia in March 2026.
| What buyers said | April 2025 | March 2026 |
|---|---|---|
| Start research with AI chatbots more often than Google | 29% | 51% |
| Use AI chatbots to research sellers | 60% | 71% |
| Say AI research is more useful than normal search | 36% | 53% |
Buyers who picked a different company than planned because of what AI told them.
Buyers who bought from a company they had never heard of until AI suggested it.
Buyers who fact-check what AI tells them. 63% used AI during the purchase.
Review sites against AI chatbots as the top influence on the buyer’s list.
G2 also found that 64% of buyers often see wrong AI recommendations. 45% say a link to a review site is what makes them trust the answer again. So being mentioned by AI and having good reviews now work together. If you run an agency, a steady flow of client reviews helps with both.
Where B2B leads come from.

B2B content and keywords.
Content Marketing Institute surveyed 1,015 B2B marketers in mid 2025.
What B2B content marketers say
Share of 1,015 marketers, 2025.
Look at the first and last bars. 87% say AI made them faster. Only 39% say it made their content work better, and 34% saw no change.
Keywords in the Ahrefs US database that get fewer than 10 searches a month. That is 2.3 billion keywords.
Fewer than 18,000 keywords get more than 100,000 searches a month. For a business with a small, specific market, many small keywords usually bring better buyers than one big keyword you cannot win.
What to do with these numbers.
6 steps for any company that sells to other businesses, including agencies.
1. Aim to be on the first list
95% of deals go to a company that was on the buyer’s first list. Your SEO goal is to be one of the 3 or 4 names a buyer writes down.
2. Make your claims easy to check
94% of buyers fact-check AI answers. Reviews, case studies and clear results pages help them trust you. For agencies, a white label reporting tool makes results easy to show.
3. Write for the comparison stage
53% of marketers struggle most with the middle of the funnel. Comparison pages, pricing pages and “how it works” pages help buyers who are choosing.
4. Expect SEO to look smaller in reports than it is
Most research happens before contact, so the first click often gets no credit. Track brand searches and assisted leads too. Our reporting tool can help agencies show this to clients.
5. Target many small keywords
About 93% of keywords get fewer than 10 searches a month. In B2B, 100 small, specific searches often beat 1 big one.
6. Check what AI says about you
33% of buyers bought from a company they first heard of through AI. Our AI visibility checker shows whether AI tools mention you.

B2B SEO statistics, answered.
What does B2B mean?

How long does a B2B purchase take?
6sense found the average B2B buying cycle is 10.1 months in 2025, down from 11.3 months the year before.
How much research do B2B buyers do before contacting a seller?
About 61% of the buying process is done before the first contact, according to 6sense in 2025. A year earlier it was 69%.
Do B2B buyers use AI to research?
Yes. G2 found that 51% of software buyers now start research with an AI chatbot more often than Google, up from 29% a year earlier. 71% use AI chatbots to research sellers.

They use them but check them. TrustRadius found 63% of buyers used AI during a purchase and 94% fact-checked what it said.
