How to Extract Publicly Listed Profile Data

Professional directories and public-facing profile pages contain publicly listed information — names, job titles, locations, and professional summaries — that businesses use for market research and lead generation.

Step-by-Step Guide

1

Target public directory pages only

Focus on publicly accessible directory listings — pages that appear in Google search results and require no login to view. Avoid platforms with explicit scraping restrictions.

2

Review terms of service

Check the target directory's terms of service before scraping. Some directories explicitly permit non-commercial data collection; others restrict it. Always comply with the platform's stated policies.

3

Fetch directory listing pages

Send the directory search result pages to AlterLab. Use filters to narrow results by industry, location, or job title.

4

Extract profile data

Parse name, title, company, and location from each profile card. Avoid extracting personal contact details not intended for public business use.

Code Example

Python
import requests
from bs4 import BeautifulSoup

def extract_profiles(directory_url: str, api_key: str) -> list[dict]:
    response = requests.post(
        "https://alterlab.io/api/v1/scrape",
        headers={"X-API-Key": api_key, "Content-Type": "application/json"},
        json={"url": directory_url, "render_js": True},
    )
    html = response.json().get("html", "")
    soup = BeautifulSoup(html, "html.parser")

    profiles = []
    for card in soup.select(".profile-card"):
        profiles.append({
            "name": card.select_one(".name")?.get_text(strip=True),
            "title": card.select_one(".job-title")?.get_text(strip=True),
            "company": card.select_one(".company")?.get_text(strip=True),
            "location": card.select_one(".location")?.get_text(strip=True),
        })
    return profiles
