How to Find Business Leads Online in 2026 (7 Methods)

The wrong way to find business leads: buy a list from some sketchy data broker, blast everyone with generic emails, and wonder why your reply rate is 0.2%.

The right way: know exactly who you're looking for, use the right data source for your target market, get clean contact information, and reach out with messages that actually resonate.

In 2026, there's more data available about businesses than at any point in history. The problem isn't access — it's knowing which sources to use for which targets, and how to extract data at a cost that makes outbound financially viable. That's what this guide covers.

Method 1: Google Maps Data Mining

Google Maps is the most comprehensive database of local businesses on the planet. Over 200 million businesses are listed, each with structured data: name, address, phone number, website, business category, hours, price range, and customer reviews.

The review data alone makes Google Maps extraordinary for lead generation. Review count is a proxy for business activity and revenue. A restaurant with 800 reviews is a different prospect than one with 12. A contractor with 200 reviews has been in business for years and has stable revenue. You can prioritize your outreach based on this signal before making a single contact.

The challenge with Google Maps is extraction at scale. Doing it manually — search, click, copy, paste — is agonizingly slow. The solution is Suplex, a desktop lead generation app that connects to Apify's Google Maps scraper. You define category and location; it returns structured lead data at $0.025/lead via your own Apify key.

For local business targeting in virtually any B2B vertical — contractors, restaurants, medical practices, law firms, agencies, retailers — Google Maps is your first-call data source.

Method 2: LinkedIn Prospecting

LinkedIn has over 1 billion members, including virtually every B2B decision-maker on earth. It's filterable by job title, company size, industry, location, seniority, and more. For any B2B target market, LinkedIn can produce a highly specific list of exactly the right people.

The limitations: LinkedIn's native tools are expensive (Sales Navigator runs $100+/month per seat), rate-limiting prevents rapid data extraction, and aggressive scraping can get your account flagged.

Ethical LinkedIn scraping at scale requires using LinkedIn's public data through compliant third-party scrapers. Suplex connects to Apify's LinkedIn actors, letting you extract structured lead data — names, titles, company, and often email — at $0.025/lead. No native LinkedIn account risk. No per-seat fees.

Use LinkedIn when you're targeting specific titles at specific company types — not "every restaurant in Austin" but "every VP of Operations at a company with 100–500 employees in the SaaS vertical."

Method 3: B2B Data Databases

Apollo.io, ZoomInfo, and Clearbit are the major players in the B2B data database space. They aggregate company and contact data from hundreds of sources and let you filter by industry, company size, revenue, technology stack, location, and job title.

The upside: fast access to enormous contact databases. The downside: expensive (ZoomInfo runs $15,000+/year for serious use), often stale data (email addresses go bad at 20–25% per year), per-export limits, and vendor lock-in — your leads live in their system, not yours.

If you're at a company with a six-figure sales budget, Apollo or ZoomInfo may make sense. If you're a small team or solo operator doing outbound, there are better options at a fraction of the cost.

Method 4: Company Websites and Web Scraping

Many industries have websites that publicly list member companies, practice directories, certification holders, or registered businesses. Bar association directories list licensed attorneys. Medical board websites list licensed physicians and practices. Contractor licensing boards list licensed contractors with contact information.

These are clean, current, and often publicly available. The challenge is extraction — these sites aren't designed for bulk data download. Apify's web scraping infrastructure (accessible through Suplex) can extract structured data from many of these sources. Custom scrapers can handle others.

For hyper-specific industries — licensed general contractors in Texas, licensed physicians in Florida, law firms in New York — this approach produces leads that pay-per-record databases often don't have.

Method 5: Job Posting Intelligence

Job postings are one of the most underused B2B lead generation signals. What a company is hiring for reveals exactly what they're struggling with and what they're willing to spend money on.

A company hiring an SDR team is building outbound capacity — they need outbound tools. A company hiring a Head of SEO is investing in content — they need SEO software and content agencies. A company hiring for IT security is expanding their security posture — they need security vendors.

LinkedIn Jobs, Indeed, Glassdoor, and company careers pages are all sources. Monitor these sources for your specific hiring signals and add matching companies to your prospecting list. These companies have demonstrated intent — they're in motion, they're spending, they need things.

Method 6: Intent Data and Technology Signals

Intent data tracks companies' online behavior — what topics they're researching, what competitor websites they're visiting, what keywords they're searching. Companies that are actively researching your category are in active buying mode.

Providers like Bombora, G2, and TechTarget publish intent data. Some B2B databases (ZoomInfo, 6sense) bundle it into their offerings. The signal quality is high; the cost is also high.

Technology data is a related signal. BuiltWith and Datanyze show what technology a company's website is running — useful for selling complementary or replacement tools. "They're running Mailchimp — they might need a step up to a proper marketing automation platform" is a genuine sales trigger.

Method 7: Referrals and Network Mining

Warm referrals close at 3–5x the rate of cold leads. A referral is an earned shortcut — someone already trusted has vouched for you, which collapses the sales process significantly.

Building a referral network requires systematically asking happy clients for introductions, maintaining relationships with complementary service providers who share your target market, and being genuinely useful to people in your network so they want to send business your way.

Referrals alone don't scale. But combined with outbound, they produce a compounding pipeline. Every cold prospect you convert into a happy client is a potential future referral source.

Choosing the Right Method for Your Target Market

Here's a quick framework for picking the right lead source:

• Local businesses (contractors, restaurants, retailers, medical practices): Google Maps via Suplex
• B2B decision-makers by title and industry: LinkedIn via Suplex
• Enterprise accounts with big budgets: Apollo or ZoomInfo + intent data
• Companies actively in buying mode: Job postings + intent data
• Licensed professionals (attorneys, doctors, contractors): Regulatory directories + web scraping
• Best quality with highest close rate: Referrals from existing clients

The Data Quality Problem — and How to Solve It

Lead data goes stale fast. People change jobs. Businesses close. Email addresses bounce. A list that's 12 months old might have 25–30% bad data.

The solution is email verification before you send. Suplex includes email verification as part of its workflow — check emails against verification APIs before they go into your sending queue. Verified emails dramatically reduce bounce rates and protect your sending reputation.

The Cost Math of B2B Lead Generation

Traditional B2B data costs $0.50–$3.00 per contact from platforms like ZoomInfo. Apollo is cheaper but still significant for high volumes. Lead generation agencies charge $50–$500+ per qualified lead.

Suplex changes the math: $0.025/lead via your own Apify key. No markup. No middleman. You pay Apify directly at cost; Suplex just automates the extraction, verification, and outreach workflow.

At $0.025/lead, a list of 5,000 targeted B2B prospects costs $125. The same list from ZoomInfo might cost $2,500–$5,000. That cost difference changes what outbound campaigns are economically viable — and who can afford to play the outbound game.
