    Hi! We're a new website looking to make a mark on Google. We need an extremely simple, super inexpensive Chrome extension We are in the jobs / hiring / HR space, and ideally would want something to do with that. However, it doesn't have to be. As we were exploring how to build domain authority, we realized that Google thinks highly of chrome extensions and their publishers in terms of SEO metrics such as Ahrefs DR, Moz DA, etc. Our goal is to publish a very simple one. We are open to what it does, as long as it doesn't capture any personal information Please share your ideas. This is a great opportunity for someone who has already built one to quickly make another project live for a new customer and add it to their project portfolio. We will give 5 stars and a great review. ...
