Edit links and add links for 35 keywords, on 210 web pages

This product involves editing the links and adding links to anchor text, in the product description text on a BigCommerce website. The 210 product pages are about 120 words of product description text per page, on average. I will give you a list of the URLs of these product pages: This project has three elements: 1. Check existing links: For any link that already appears on the pages: Check the link to see if it 301-redirects to another URL, and if so, change the URL of the link to the new URL. I will give you a guideline to identify these "old links" fast. 2. Add links to certain anchor text that is not already linked: I will give you a list of 35 keywords and keyword phrases (some of these will be short-tail keywords and some long-tail keywords), and to the right of each of these keywords is the link to link the keyword (anchor text) to. So, when you see these keywords in the product description text of any of the pages, add the designated link to this anchor text. 3. Most of the 210 product pages have a sentence about "gender determination" of the cable connectors, that already has a link or links to certain pages: I'm going to give you a single URL to link all of this anchor text, that is related to connector gender. If you do a good job on this project, we've got another 600+ pages that need the same work done, and I will set that up as another project or projects, after this one is complete. I will provide a list
