Scraping Facebook posts without logging in may sound unbelievable, but it is indeed possible. This guide will demonstrate how to extract posts from public Facebook profiles using a Python-based scraper. While Facebook restricts the collection of private data, public pages offer ample opportunities for competitor analysis and influencer research.
To get started, ensure you have JSON, Python, and the Facebook scraper installed. The installation process is straightforward; simply use a pip install command in your command line interface. It is advisable to review the documentation available on GitHub for detailed instructions.
Due to recent updates on Facebook, some adjustments to the scraper are necessary. First, modify the driver_utilities.py file to prevent the cookie consent prompt from interfering with the scraping process. Additionally, if you plan to scrape multiple pages simultaneously, update the scraper.py file to ensure that data from different sources is saved in separate files.
To implement the required changes, locate the 'wait_for_element_to_appear' function in driver_utilities.py and add the necessary code. In scraper.py, move specific lines to the init() method and prefix them with 'self.' to ensure proper functionality. Remember to save your changes before proceeding.
Next, create a new text file in your chosen directory and rename it to facebook1.py. Open this file and import the scraper. Define the public profiles you wish to scrape by entering them as string values. You can choose to scrape multiple pages or focus on one at a time.
Select a proxy provider, such as Smartproxy, to enhance your scraping experience. Specify the number of posts you want to scrape, choose your preferred browser (Google Chrome or Firefox), and set a timeout variable to define how long the scraper should run during inactivity. The headless browser variable can be set to 'false' to view the scraping process or 'true' to run it in the background.
If your proxy provider requires authentication, input your username and password in the proxy variable, separated by a colon. Initialize the scraper by passing the page title, post count, browser type, and other parameters as function arguments. Choose your output method: either display the results in the console or export them to a CSV file.
For console output, ensure you have JSON set up correctly. If opting for CSV export, create a directory for the results and configure the code to save data from each Facebook page with appropriate titles. Implement proxy rotation to safeguard against IP bans, and then run your script in the command line.
Upon running the scraper, results will be displayed in a matter of seconds. The output will include the account name, along with the number of shares, reactions, and comments. The content key will show the post itself and any links to images or videos. Given Facebook's strict policies against scraping, using high-quality residential proxies is essential for maintaining a successful scraping operation.
When selecting a proxy provider, prioritize residential proxy services for better success rates. These proxies can help you navigate Facebook's restrictions more effectively. For further guidance on choosing the best residential proxies, additional resources are available.
