@imelbel Hi, you can search "Web Scraping" on YouTube, there will be tons of information pop up. Basically, it's a process of using bots to extract data from a website. Many investors use this technique to extract and analyze data from Zillow and Redfin and pricing offers accordingly.
But beware things can become tricky if these websites detect your IP address when you extracting data from them. The result will be banning you from access to their website temporarily or permanently. To prevent this from happening, many people use VPN or Proxy server to hide their IP address. There are also other methods that can be used to prevent website discovering you.
Land Academy has some information on the subject and they use Web Harvey(their YT channel is called sysnucleus) to do the job.
I hope this helps.
