Node.JS+Puppeteer: Website crawler - AdChecker

Hi, I developed a website crawler which does the following: -> Visits a site -> Takes a screenshot and saves it within a folder with the site's name -> Clicks on the first GoogleAd -> Takes a screenshot of the ad's destination URL and saves it within the folder of the refering site. Nevertheless, the program does not work in every case. My Javascript/Node.js capabilities are limited, so I was looking for a developer to help me out with: 1- Improve my selector/xpath query and follow multiple ads The way its implemented today, I can follow the first ad in most of the cases but it does not work always. The program should be able to follow up to 3 ads, if they exist, and work regardless of the site. *I will provide some test sites 2- Handle/prepare for promise rejections At the moment my implementation ignores promises, I need the program to react accordingly when timeouts or rejections occur. You will need to have Node.js installed and the node_modules:puppeteer and mkdirp downloaded. Please submit a bid only if you have experience working with puppeteer, node.JS and webscraping. I will provide all necesary files.
