How Do I Scrape Data From a Website Automatically?
Scrape data from a website automatically, such as prices, listings, or availability, on a schedule. How web scraping works and how AI can write the script.
How Do I Scrape Data From a Website Automatically?
There is information on a website that you need regularly. Competitor prices. Job listings. Property listings. News articles. Product availability. Right now you visit the site, copy the information, and paste it somewhere useful. You do this every day or every week and it takes longer than it should. Web scraping is the practice of automatically extracting data from websites, and your AI can write a script that does this for you. Here is how to approach it.
What Web Scraping Is
Web scraping means writing a script that visits a website, reads its content, and extracts specific pieces of information automatically. Instead of you visiting a site and copying data, the script does it on a schedule and saves the results wherever you need them.
A one-sentence definition: web scraping is an automated process that extracts specific data from websites and saves it in a structured format you can use.
Common business uses: tracking competitor prices, monitoring job boards for relevant listings, collecting customer reviews from multiple platforms, aggregating news from specific sources, tracking stock availability.
Before You Start: Check for an API or Data Export
Before writing a scraper, check whether the site offers a better way to get the data.
Many websites have a public API that provides the data in a clean, structured format. This is much more reliable than scraping. Check the website’s footer for “API” or “Developers,” or ask your AI: “Does [site name] have a public API for accessing [the data you want]?”
Some sites also have export features: download as CSV, export to spreadsheet. If the data is available this way, use it rather than scraping.
Scraping is the right approach when no API exists and no export is available.
The Legal and Ethical Reality
Before scraping any website, two things to know:
Check the website’s Terms of Service. Many sites prohibit automated scraping in their terms. Scraping a site that prohibits it creates legal risk. Look for terms about “automated access,” “bots,” or “scraping.”
Do not scrape at a rate that affects the site’s performance. A script that makes thousands of requests per minute to a small business’s website can effectively take it down. Be polite: add delays between requests and scrape only what you need.
Publicly available data scraped respectfully is generally accepted practice. Scraping data behind a login, scraping personal information, or using scraped data to harm the site’s business is not.
How to Build a Web Scraper With Your AI
Tell your AI exactly what you need:
“I want to automatically scrape [describe what data] from [the URL of the page]. The data appears in [describe where on the page, e.g. a table, a list of items, specific sections]. Save the results to [Google Sheets / a CSV file / a database]. Run the scraper [daily / hourly / weekly]. Can you write a Python script using BeautifulSoup or Playwright that does this?”
Your AI will write a script using either BeautifulSoup (for simple HTML pages) or Playwright (for pages that load content dynamically with JavaScript). It will show you how to install the dependencies and run it.
Running Your Scraper Automatically
A scraper that only runs when you remember to start it is not much better than doing it manually. Schedule it:
GitHub Actions runs your script on a schedule in the cloud for free. Ask your AI: “Can you create a GitHub Actions workflow that runs my scraper every day at 7am and saves the results to a Google Sheet?”

When Scraping Gets Blocked
Websites often implement measures to block scrapers: CAPTCHAs, rate limiting, or detecting non-human browser behaviour. If your scraper gets blocked:
Ask your AI: “My scraper is being blocked by [site name]. Can you add headers that make the requests look more like a regular browser, add random delays between requests, and handle the case where the expected content is not found?”
For heavily protected sites, consider whether a data provider sells the data you need, which is often cheaper than the engineering time to bypass protections.
The One Thing to Remember
Web scraping automatically extracts data from websites on a schedule. Check for an API or export first. Respect Terms of Service and scrape politely with delays. Ask your AI to write a BeautifulSoup or Playwright script describing exactly what data you want from which URL. Schedule it with GitHub Actions to run automatically without your involvement.
