If you’re not familiar with programming, you can consider hiring a developer or utilizing pre-built scraping scripts available online.
Step 5: Execute the Scraping Script
Run the scraping script and let it crawl through Zillow’s website to collect the desired data. Depending on the amount of data and complexity of the website structure, the scraping process may take some time. Be patient and ensure your internet connection is stable to avoid interruptions.

Once the scraping process is complete, you will have a raw dataset that may require cleaning and formatting. Data cleaning involves removing duplicates, handling missing values, correcting inconsistencies, and ensuring data uniformity. Formatting the data involves organizing it into a structured format, such as CSV or Excel, for further analysis.
Step 7: Analyse and Extract Insights
With the scraped and formatted data at your disposal, it’s time to dive into analysis and extract valuable insights. This could involve various techniques, such as statistical analysis, data visualization, and machine learning algorithms.
