Automated Web Data Collection with Browser Use
Step-by-Step Guide
-
Install Browser Use
pip install browser-use. Set up Playwright browsers: playwright install chromium. Configure your LLM (OpenAI/Claude). Test with a simple navigation task to verify setup is correct.
-
Define Collection Task
Write a natural language instruction: Go to [website], navigate to [page type], for each [item], extract [fields: name, price, description, rating]. Handle pagination by clicking next page button. Stop after 50 items.
-
Add Login Handling
If the site requires login, provide credentials in the task: First, log in with username [USER] and password [PASS]. Then navigate to the data pages. Browser Use will handle the login form automatically.
-
Data Validation
Add a post-processing step that validates extracted data: check for missing fields, validate data types (price is number, rating is 1-5), deduplicate by unique identifier. Use Python pandas for data cleaning.
-
Export and Schedule
Save extracted data to CSV/JSON. For recurring collection, wrap in a cron job or n8n workflow. Add error handling: retry failed pages, log blocked requests, send alert if collection success rate < 80%.
