Brian, I’m going through Step 3, which is referring to the one version of the website. I found a very good free tool (https://varvy.com/tools/redirects/) to recommend. It checks on the redirect and gives you a visual number of hops. More hops mean more delay. For example, if I use your manual method to check on https://uprenew.com, all looks good. However, if I use the tool and check, I realize there is an unnecessary 1 hop/delay, whereby I can fix it. Hope this helps. : )
Ahrefs is an excellent tool for SEO and Content Marketing. However, it may not fit those who have a low budget, are casual bloggers or those trying to start a new niche. This is also not for webmasters who don't do frequent updates. Ahrefs is not cheap. But, with its ability to replace many tools and its unique functions, it can be worth the investment.
