Google Leads Scraper
This project is a Python-based web scraper that makes it easy for marketers to extract emails and phone numbers from Google search results. The scraper accepts search queries and launches Google for content surrounding this query. The scrapper ignores content from dictionaries or YouTube.

The scrapper extracts phone numbers and emails from opened websites and then takes a screenshot of the page. Screenshots are stored in the static folder, and the text data are stored as a comma-separated values (CSV) file under whatever file name the user specified on the execution command.
