LeadHunter — Google-Powered Email, Phone & Website Extractor

Find verified B2B leads in seconds using real-time Google search data. Extract emails, phone numbers, and websites automatically — no manual copy-pasting ever again.

Why LeadHunter?

Most lead generation tools rely on outdated databases. LeadHunter is different — it searches Google in real time using the Serper.dev API, so every result is fresh, relevant, and up to date . You control the keywords, country, language, and date range. The app does the rest.

Whether you are building a prospect list for cold outreach, recruiting candidates, or researching competitors , LeadHunter delivers structured contact data — email, phone, and website — directly to a clean results grid, ready to export.

✨ Key Features

Real-Time Google Search via Serper.dev API

Every search runs live on Google. No stale databases. No recycled contact lists. Results are pulled directly from Google search results in 1–2 seconds per query, giving you the most current data available.

Smart Email Extractor with Validation

Extracts email addresses from Google snippets and crawled web pages. Handles standard and obfuscated formats (name [at] domain [dot] com). Multi-layer validation automatically filters out:

Generic role addresses: no-reply, info, support, admin, sales, marketing
Invalid TLD formats (numeric or malformed domains)
Duplicate emails across all queries (auto-deduplication)

Phone Number Extractor & Normalizer

Detects international phone numbers from search snippets and web pages. Automatically normalizes formatting based on the selected country/region code.

Website Extractor

Automatically extracts the root domain from every result source URL, giving you a clean, ready-to-use website column for every lead.

Intelligent 3-Step Web Crawler

When no email is found in the Google snippet, the built-in web crawler automatically digs deeper — following a smart 3-step strategy to maximize email discovery while minimizing unnecessary requests:

Step 1 — Home Page: Fetches the website home page and scans for emails. Stops immediately if found.
Step 2 — Contact Pages (Serial): Identifies and fetches contact-related pages (/contact, /about, /team, /people, /staff, /company). Stops as soon as an email is found.
Step 3 — Sub-Pages (Concurrent): Discovers sub-links from contact pages and fetches them concurrently. Stops the moment any page yields a valid email.

Blocked domains (LinkedIn, Facebook, Twitter, Instagram, YouTube, TikTok) are automatically skipped to save time and quota.

Multi-Parameter Search — Cartesian Product Queries

Enter unlimited keywords and unlimited email domains. LeadHunter automatically generates every combination as a separate query:

Unlimited keywords × Unlimited email domains × Unlimited site filters = fully automated Cartesian product queries
Example: 5 keywords × 3 email domains × 4 site filters = 60 unique Google queries — all run automatically

Country, Language & Date Range Filters

Country (gl): Localize results to any of 240+ supported countries
Language (hl): Filter results in any Google-supported language
Date Range (tbs): Past Hour / Past 24 Hours / Past Week / Past Month / Past Year / Any Time

Site Filter (DomainList)

Restrict searches to specific websites using the Google site: operator. Enter one domain per line to target platforms like LinkedIn, Crunchbase, or specific industry directories.

Real-Time Results Grid

Results appear live as they are found. Every row shows: Title, Email, Phone, Website, Source URL, Extracted At. Scroll, sort, and review leads while the search is still running.

Real-Time Crawl Log Monitor

A timestamped log panel shows every action the crawler takes, so you always know exactly what is happening:

[10:32:11] Fetching home: https://example.com
[10:32:12] Found 3 contact page(s).
[10:32:13] Fetching contact: https://example.com/contact
[10:32:14] <strong>Email found on contact page.</strong>

⚡ Auto Rate Limit Management

Serper.dev limits requests to 25 per minute. LeadHunter monitors this automatically. When the limit is reached (HTTP 429), the app waits and retries up to 3 times — no manual action needed.

API Quota Display

Your remaining Serper.dev API balance is shown in the toolbar and refreshed after every search. The free plan provides 2,500 queries — no credit card required to get started.

One-Click Export to CSV / Excel

Export all results to CSV or Excel (.xlsx) with one click. All columns are included: Email, Phone, Website, Title, Extracted At.

❓ FAQ

Is LeadHunter legal to use?

LeadHunter only accesses publicly available data from Google search results and public web pages. Users are responsible for complying with applicable data protection laws (GDPR, CAN-SPAM, etc.) when using extracted contact data.

How many leads can I find with 2,500 free queries?

With 3 pages per query (30 results), 2,500 queries can return up to 75,000 search results. The number of valid leads depends on query quality — typically 2–10 leads per query.

Does it work for any country or language?

Yes. LeadHunter supports all 240+ countries and 80+ languages supported by the Google Search API via the gl and hl parameters.

Can I run multiple searches at once?

LeadHunter employs concurrent processing for queries, while utilizing concurrent fetching when scraping sub-pages to achieve maximum speed.
