I Published 100 Web Scraping Tutorials — Here Is What I Learned

I just hit 100 articles about web scraping on Dev.to. Here are the key lessons.

Lesson 1: APIs Beat HTML Parsing 95% of the Time

Most popular websites have JSON APIs. 7 sites return JSON directly without any scraping.

Lesson 2: Three Tools Cover Everything

• fetch() — for JSON APIs (covers 70% of jobs)
• Cheerio — for static HTML (25%)
• Playwright — for dynamic sites (5%)

Lesson 3: Rate Limiting Is More Important Than Proxy Rotation

Random delays of 2-5 seconds between requests prevent 90% of blocks.

Lesson 4: Validate Every Output

Never return garbage. Check every field before adding to results.

Lesson 5: The Real Money Is in Lead Generation

Business owners pay the most for contact data extraction.
