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. : )
Pros: The main thing about Semrush is versatility and SEO functionality, but beside SEO there are lot of things you cqan do with, such as: brand monitoring, position tracking, SEO ideas and backlink audit. If you are not familiar with it, you can watch tutorials which are extremely helpful, but the one thing you should now is that you might be overwhelmed with lot of information about this platform. The price is affordable but it might be expensive for small size businesses. I like the competitor tracking because it is useful and it allows you to see competitor backlinks.
