Web Scraping

Learning Objectives

• Apply ethical and legal considerations when using web scraping tools professionally

Web Scraping in the AI Era

Web scraping is extracting structured data from web pages at scale. The AI era has changed web scraping in two ways:

First, AI tools need access to current web content as input — a coding agent that can search the web, an RAG system that indexes competitor websites, a research agent that reads many pages simultaneously. These use cases require scraping tools optimized for LLM consumption.

Second, AI has made scraping easier. Instead of writing custom CSS selectors and XPath queries for each site, some tools can infer the data structure from a visual instruction — you show it what to extract, and it figures out the selectors.

Firecrawl — LLM-Ready Web Content

Firecrawl is the preferred tool for developers building AI applications that need to access web content. The key design decision: Firecrawl converts web pages to clean Markdown rather than returning raw HTML — producing output that LLMs can read and reason over without HTML parsing.

Core capabilities:

Single URL crawl:

from firecrawl import FirecrawlApp
app = FirecrawlApp(api_key="...")
result = app.scrape_url("https://example.com/page",
                         params={"formats": ["markdown"]})

Site crawl: Crawl an entire website, following internal links and returning clean Markdown for each page. Used for ingesting documentation sites, competitor websites, or knowledge bases into RAG systems.

Structured data extraction: Provide a JSON schema and Firecrawl extracts structured data matching that schema from any page — useful for extracting product prices, contact information, or specific data types without writing custom selectors.

Map endpoint: Returns all URLs on a domain — useful for understanding site structure before crawling.

For AI agent workflows where the agent needs to read external web content, Firecrawl is the standard integration because its Markdown output is immediately usable without post-processing.

Apify — Enterprise Scraping Platform

Apify is a scraping infrastructure platform with 2,000+ pre-built scrapers (called "Actors") for specific websites:

• Amazon product scraper
• LinkedIn people and company data
• Google Maps business listings
• Instagram and TikTok data
• E-commerce price monitoring across major retailers

The pre-built Actors are the key value: common scraping targets are already handled, tested against site changes, and maintained by the Apify community. Teams can run them with configuration rather than code.

For custom targets, Apify's scraping SDK supports Puppeteer (Chrome automation) and Playwright (cross-browser), with cloud execution that handles proxies, rate limiting, and scaling automatically.

Apify's platform runs scrapers in the cloud — no local infrastructure, usage-based pricing, scheduling and webhooks for automated runs.

Browse AI — No-Code Visual Training

Browse AI lets non-developers extract data from any website without writing code:

1. Click the Chrome extension and navigate to the target site
2. Click on the data you want to extract — Browse AI learns the pattern
3. Deploy the "robot" to run on schedule and extract fresh data automatically
4. Monitor the site for changes and receive notifications when data changes

Browse AI excels at: price monitoring, competitor tracking, lead list building from directories, extracting structured data from sites without APIs. The no-code approach makes it accessible to business analysts and researchers who aren't developers.

Diffbot — Automatic Structured Extraction

Diffbot uses AI to automatically identify and extract structured data from any web page without requiring custom selector configuration. Submit a URL; Diffbot determines the page type (article, product, profile, discussion) and returns structured JSON with appropriate fields extracted.

For an article: headline, author, date, body text, images, sentiment. For a product: name, price, description, SKU, images, availability. For a business page: company name, contact information, description, employees.

The appeal: zero configuration for common page types. The limitation: works best on conventional page structures; highly custom layouts may require Diffbot's enhanced extraction features.

SerpAPI — Search Result Data

SerpAPI extracts structured data from search engine results pages (SERPs) via API — Google, Bing, DuckDuckGo, YouTube, and others.

Use cases:

• Competitive research: track where competitors rank for specific keywords
• Market research: understand what topics are driving search interest in a category
• AI agent integration: enable an agent to "search Google" and receive structured results without scraping Google directly (which violates Google's ToS)

SerpAPI handles the complexity of appearing as a legitimate browser and rotating IPs — the scraping infrastructure is managed, and you receive clean JSON.

Apollo.io — B2B Data and Prospecting

Apollo.io is distinct from pure scraping tools: it's a B2B prospecting database with 270 million contacts and 70 million companies, enriched from public web data, LinkedIn, company websites, and partner data sources.

Use cases: finding contact information for specific roles at target companies, building prospecting lists, enriching CRM records with company and role data, LinkedIn outreach automation.

Apollo sits at the intersection of web scraping, database, and sales tool — relevant for sales and marketing teams, not for general web data extraction.

Choosing the Right Tool

Key Takeaways

• Firecrawl is the default choice for developers building AI applications — it converts web content to LLM-ready Markdown and is designed specifically for AI pipeline integration
• Apify provides enterprise-scale scraping infrastructure with 2,000+ pre-built scrapers for major sites, eliminating custom scraper development for common targets
• Browse AI enables non-developers to build and schedule data extractors through visual training — no code required
• Always verify ToS and robots.txt before scraping; many sites prohibit automated access and rates that stress their infrastructure
