AppleScript To Track website's position on google organic search

Hello, I need to track the position of my websites on google in a spreadsheet over time. I'm looking for a simple applescript that pops up a dialog, asking for a website URL, and then it kicks back the website's position on googles organic search results. I'll be able to take care of building the rest of the script that runs on a loop with multiple keywords, and enters data in a spread sheet, just need the bit of code to track the results, I'm not good enough to figure that bit out. Please build a "Run Only" version for me to test to prove that you're able to do it.
