List of B2B Websites by Industry
Every company that sells to other companies has a website, from global carriers to the machine shop down the road. Put those websites into industries and countries, and you have the backbone of a target account list, a market sizing model or a CRM clean-up.
Our data holds about 16.2 million business websites, each with IAB industry tiers, country, audience personas and popularity among real users.
Why the website is the best key for B2B data
Company names are messy: legal names, trading names, abbreviations and translations. The website domain is short, unique and already present in almost every B2B system.
Unique
Two companies can share a name. They cannot share a domain, so matching is exact.
Everywhere
Work emails, CRM records, ad logs and invoices all carry a domain, so the list joins to all of them.
Self-described
The site says what the company does, in its own words, which keeps industry labels close to reality.
Current
Websites change when businesses change direction. Regular refreshes pick that up faster than annual registries.
Two ways to define a B2B website
"Business website" can mean the company's own site, or any site about business. The database supports both, and the counts differ.
Business category
Domains whose web filtering category includes Business: company sites, service providers, manufacturers, agencies and trade bodies.
IAB Business and Finance
Domains whose main IAB topic is Business and Finance. Broader, because it also includes business news, economy and finance topics.
IAB Industries branch
Domains placed under the Industries branch of Business and Finance, which is where industry labels such as Manufacturing or Aviation live.
IAB Business branch
Domains about business functions rather than industries: marketing, logistics, HR, business IT and small business topics.
B2B websites by industry tier
Industry is where a B2B list becomes useful. These counts show sites with an IAB Business and Finance topic, by Tier 3 label, among the 300,000 most visited domains, where well-known companies cluster.
| IAB Tier 3 label | Branch | Popular sites |
|---|---|---|
| Retail Industry | Industries | 11,537 |
| Government Business | Business | 6,458 |
| Manufacturing Industry | Industries | 4,705 |
| Education industry | Industries | 3,549 |
| Financial Industry | Industries | 2,987 |
| Business Banking & Finance | Business | 2,064 |
| Logistics and Transportation Industry | Industries | 1,611 |
| Marketing and Advertising | Business | 1,545 |

10 well-known B2B websites
Among the most visited business sites, these are well-known companies that sell mainly to other businesses, listed in order of popularity among real users.
Several of these firms also serve consumers, which is normal for B2B: shipping, payments and software are bought by businesses but often touched by the public. The industry labels describe what the site is about, so they still place these companies in logistics, payments, HR services or consulting. Large brands like these are useful as test cases when you check how a list treats your own best customers.
Business websites by domain ending
The .com ending holds the most business sites by far, but country endings matter for local B2B work. Counts are domains in the Business category across the whole database.
| Ending | Business domains | Share of all domains on that ending |
|---|---|---|
| .com | 7.30 million | About 15% |
| .de | 1.44 million | About 15% |
| .org | 593,000 | About 16% |
| .uk | 589,000 | About 19% |
| .fr | 451,000 | About 21% |
| .br | 450,000 | About 30% |
| .nl | 383,000 | About 19% |
| .net | 379,000 | About 12% |
| .eu | 277,000 | |
| .ru | 274,000 | |
| .ch | 244,000 | |
| .it | 240,000 | |
| .au | 225,000 | |
| .jp | 211,000 |
Many companies use .com while serving one country, so for territory work the country field is usually better than the ending. Brazil stands out: almost a third of all .br domains are business sites. See Germany domains, France domains and the top-level domains list.
Where popular business sites are based
Among the business sites in the 300,000 most visited domains, these countries lead where a single country is clear. Many large companies serve several countries and have no single country set.
United States
The largest single market for popular business sites.
Brazil
A strong business web, also visible in the high .br share.
India
Fast-growing services, logistics and public sector sites.
Italy, Germany, United Kingdom
Europe's largest business webs by popular sites.
France, Japan, Spain
Next in line, each with strong local B2B ecosystems.
Netherlands, Poland, Turkey
Large trading and manufacturing economies with active company sites.
Using a B2B website list for lead generation
A list of company websites does not replace a sales tool, but it fixes the step most tools get wrong: knowing which companies exist in your market at all. Contact tools can only enrich accounts you already know about, so the account universe has to come first.
Size the market
Count business sites by industry and country to see how many accounts really exist.
Define the ICP
Pick industries, countries and popularity bands that match your best customers.
Build the account list
Pull matching domains as your target accounts, one row per company website.
Enrich and contact
Match domains to your CRM and contact tools, then reach out with industry-specific messaging.
Measure coverage
Compare won deals with the list to see which industries and markets convert best.
More on this workflow on the lead generation and sales intelligence page.
Other B2B uses
CRM enrichment
Add industry labels to accounts that only have a website. See data enrichment services.
Lead routing
Take the company domain from a work email, look up its industry and send the lead to the right team at once.
Territory planning
Balance sales territories by the number of real target companies per country and industry.
Account-based ads
Target or exclude business sites in ad campaigns, or find trade publishers for an industry.
Market research
Track how many companies serve a niche, country by country, and how that changes over time.
Supplier and risk checks
Confirm that a supplier's website matches the industry it claims before onboarding.
B2B audience personas
Personas describe who visits a site. For B2B lists they help tell apart sites for executives, specialists and small business owners. Counts are across the whole database.
| Persona | Domains | Useful for |
|---|---|---|
| Financial Analyst | 12.3 million | Finance, banking and investment sellers |
| Corporate Executive | 6.8 million | Enterprise software, consulting, events |
| E-commerce Entrepreneur | 4.2 million | Commerce platforms, payments, logistics |
| Brand Manager | 2.8 million | Agencies, marketing technology |
| Change Management Expert | 2.6 million | Consulting, training, HR technology |
| Equipment Supplier | 1.6 million | Industrial distribution, manufacturing |
| Business Owner | 1.6 million | Small business banking, accounting, payroll |
From website to industry code
Many B2B teams think in SIC or NAICS codes rather than IAB labels. The two can work together.
IAB industry tiers
Describe what the website is about. Fast to apply to any domain and consistent across countries.
SIC and NAICS codes
Describe the registered business activity. Common in government statistics, credit data and many CRMs.
Using both
Our SIC and NAICS codes by website page shows how website categories relate to industry codes. See also website to industry.
What a B2B website list does and does not contain
Included
Company domain, Business and other web filtering categories, IAB industry tiers up to Tier 4, country where clear, personas and popularity groups.
Not included
Names, emails, phone numbers or other personal data. The list is about companies' websites, not people.
Formats
CSV, JSON or Parquet, with only the columns you choose. See domain list download formats.
Single checks
Before buying, check a few of your own accounts with a website category lookup to see the labels they get.
Licence
Use the list inside your company or inside your own product. Reselling or publishing the raw list is not allowed.
Refreshes
The data is refreshed regularly. For ongoing prospecting, a new cut each quarter keeps the account list in step with the market.
Popularity as a rough size signal
Website visits are not revenue, but they do separate household names from small local firms. Popularity groups give B2B lists a quick, rough size dimension.
| Popularity band | Typical companies | Typical sales motion |
|---|---|---|
| Global top 100,000 | Multinationals, platforms, national leaders | Enterprise sales, long cycles, named accounts |
| 100,000 to 1 million | Large regional firms, strong mid-market brands | Mid-market sales, account-based marketing |
| 1 million to 10 million | Established small and medium-sized companies | Inside sales, partner channels |
| Not ranked | Micro businesses, sole traders, new firms | Self-serve products, marketing at scale |
Worked example: a logistics software vendor
A company selling route planning software wants every mid-sized transport and distribution firm in Germany, Austria and Switzerland. Here is how the list is built.
Category
Business, plus Automotive & Transportation where present.
Industry
IAB Logistics and Transportation Industry, and the Logistics label under Business.
Countries
Germany, Austria and Switzerland, by the country field and the .de, .at and .ch endings.
Size
Country popularity groups that skip the very largest carriers and the smallest sole traders.
Account list
A file of company domains ready to load into the CRM and match against existing customers.
The same pattern works for any vertical. Swap the industry label and the countries, keep the rest, and review a sample of the result before the first outreach.
Cleaning a B2B website list
Company website lists have their own pitfalls. A short clean-up before loading them into a CRM saves a lot of confusion later.
Country editions
One company may run brand.de, brand.fr and brand.com. Decide whether you count companies or websites, and group editions if needed.
Subsidiaries and brands
Large groups run many brand sites. Linking them to a parent account is a CRM task, not something the domain alone can tell you.
Parked and dormant sites
Leave out domains categorized as parked or for sale. They look like companies in raw lists but sell nothing.
Free email domains
When routing inbound leads, ignore webmail domains. Only a company's own domain tells you its industry.
Directories and media
Business directories and trade news sites carry business topics too. Remove them from account lists, or keep them as channels for ads.
Existing customers
Match the list against your CRM first, so outreach goes to new accounts and customers get the right message.
Industry views to start from
If you already know your vertical, these ready industry pages show what the data holds for it.
Professional services
Legal services domains and accounting domains for firms that sell expertise.
Technology
Cybersecurity domains and the list of technology websites for software and IT sellers.
Finance and insurance
Insurance domains and the list of finance websites for banks, insurers and fintech.
People and HR
Human resources domains and the list of job and career websites.
B2B websites: questions
How many B2B websites are in the database?
About 16.2 million domains carry the Business category, and about 24.6 million carry the IAB Business and Finance topic. Both are part of a database of over 120 million categorized domains.
Can I get B2B websites by industry?
Yes. Business sites carry IAB industry tiers such as Manufacturing Industry, Logistics and Transportation Industry or Management Consulting Industry, so lists can be cut by industry.
Which industries have the most popular business websites?
Among the 300,000 most visited domains, retail, government business, manufacturing, education and financial industries have the most business sites.
Does the list include contact names or emails?
No. It is a list of company websites with industry categories, country, audience personas and popularity groups. You can join it to your own CRM or contact data.
How do sales teams use a list of B2B websites?
To size markets, build target account lists, enrich CRM records with industry labels, route inbound leads and plan territories by country and industry.
Can I filter by country?
Yes. Business sites can be filtered by the country they serve and by domain ending, for example only .de or .co.uk company sites.
Can a company website carry more than one industry?
Yes. Websites can carry several categories, ranked by how much of the site they describe. A firm that makes and repairs machines can show both manufacturing and services.
How do I tell B2B from B2C companies?
The Business category and the IAB Industries branch lean towards companies selling to companies. Retail and shopping sites lean towards consumers. Many firms do both, so a quick review of your top accounts is still worthwhile.
Can I match the list to my CRM?
Yes. Normalise the website field in your CRM to a plain domain, then join on it. Accounts that match get industry, country and popularity fields in one step.
Is the list up to date?
The data gets regular refreshes, and new domains are added as they appear. Ask for a fresh cut before each campaign or territory plan.
