Capturing search data from other websites
You can check the http referrer and see what values have been put in the GET variable, but this is restricted to GET variables ONLY!
Is there a way to capture search data from other websites? For example, if a user visits any website with a search field, I am interested in what that user types into that search field to get to the desired blogpost/webpage/product. I want to know if this is possible by scraping the site, or by any other means. Also, is it illegal to perform a scraping operation to record such data on a third party website? Also, if this is possible using PHP and Python?
