What B2B research looks like
Sales and growth teams constantly research companies: which businesses fit their ideal customer profile, which are growing, what technology they use, where they operate and who might be the right contact. Much of the useful information about companies is public: company websites, product pages, pricing pages, press releases, job postings, public registries and directories.
Collecting it at scale runs into rate limits and blocks, and some sources show different content by region. Geonode proxies help with the company-data side of this work. This guide focuses on doing it in a way that respects platform rules and data protection law, because B2B lead research is an area where it's easy to cross lines.
Company signals worth collecting
| Signal | Where it comes from | Why it matters |
|---|---|---|
| Company size and locations | Company websites, registries | Fit with your target market |
| Technology used | Website source, scripts, DNS records | Fit with your product, integration opportunities |
| Hiring | Career pages and job boards | Growth and priorities. See job market data |
| Pricing and products | Pricing and product pages | Competitive positioning |
| News and funding | Press pages, news sites | Timing for outreach |
| Regional presence | Localised sites, regional pages | Market expansion signals |
Product choice
- Company websites: usually lenient. Use no proxy or rotating datacenter traffic at polite rates.
- Directories and registries: varies. Many public registries offer official bulk data or APIs; use those first.
- Protected aggregators and review sites: rotating residential, at modest volumes.
- Regional checks: residential with country targeting to see localised company sites.
Technology detection
Many sales teams want to know which tools a company's website uses. You can detect much of this from the HTML and scripts a site loads, with a single lightweight request per site. Datacenter traffic is usually fine. Be polite: one request per site per check is plenty.
Proxy tip: Before scaling, run a short pilot on your real targets with Geonode and record success rate, latency and GB per result. Our our complete Geonode guide explains which Geonode product to start with.
Where the lines are
Personal data
Names, email addresses, phone numbers and profiles of employees are personal data, even when they're publicly visible. Data protection laws such as GDPR apply to collecting and using them for marketing, and many jurisdictions also regulate unsolicited email and calls. If you build contact lists, you need a lawful basis, transparency, an opt-out process and data minimisation. Many teams use licensed B2B data providers that handle these obligations.
Professional networks
Professional networking platforms strictly prohibit scraping and automation, and enforce it. Proxies don't make that safe or allowed. Use official sales tools and APIs. See Geonode for LinkedIn.
Email harvesting
Collecting email addresses from websites for bulk outreach is restricted or prohibited in many jurisdictions and is a fast way to damage a sending domain's reputation. Don't.
A responsible workflow
- Build a company list from your CRM, public registries or licensed data.
- Enrich with company signals from company websites: technology, locations, products, hiring.
- Score companies against your ideal customer profile.
- Find contacts through compliant sources: licensed providers, inbound leads, events, official platform tools.
- Document your sources and legal basis.
Costs
Company websites are light, and one request per site goes a long way. Most B2B enrichment jobs use little bandwidth, much of it on datacenter traffic. Geonode's non-expiring residential balance covers the occasional protected source.
Enrichment signals from a single page load
A company's home page and a couple of key pages reveal a surprising amount with one light request each:
- Technology: analytics, tag managers, chat widgets, e-commerce platforms and frameworks referenced in the page source.
- Market focus: languages offered, regional sites and currencies.
- Business model: pricing pages, "book a demo" versus "buy now" calls to action, free trial offers.
- Size hints: number of locations listed, careers page activity, customer logos.
- Recency: blog and press dates showing whether the company is active.
Collect these at a polite rate, mostly through Geonode datacenter traffic or no proxy at all, and refresh quarterly. Residential exits are useful when a company's site shows different regional versions and you need the local one.
Keeping a clean, compliant dataset
- Store company facts separately from contact data, with different access controls and retention.
- Record the source and date of every field.
- Honour opt-outs promptly and keep a suppression list.
- Review data quality regularly: dead domains, merged companies and stale signals.
A smaller, accurate, compliant dataset beats a large, stale one, both for sales results and for your legal position. See Geonode for market research for research methods that complement lead work.
FAQ
Can I scrape company websites for lead research?
Collecting public company information from company websites at polite rates is common. Personal data and platform rules are where care is needed.
Is it legal to collect business email addresses?
It depends on the jurisdiction and how you use them. Business contact data is still personal data in many places. Get advice before building contact lists.
Do I need residential proxies for B2B research?
Rarely for company websites. Sometimes for protected aggregators and regional checks.
What's the safest source of contact data?
Licensed B2B data providers and people who've opted in to hear from you.
Editorial note: Proxy providers change their pools, features and prices often, so treat any figures here as typical ranges at the time of writing and confirm current terms with the provider before you buy.
