For XML sitemap files, Google recommends using entity escape codes. https://www.google.com/webmasters/tools/docs/en/protocol.html#escaped When I change my ampersands to & in my XML file and then try to visit the link after it's been changed, the link is broken. It shows the page template and title but but no product because it is a query string page. Should I worry that the link is now broken from my end or will Google be able to crawl this anyways?
