Welcome to the Q&A Forum

Hello, thanks for your suggestion! I've double checked all of these items. The only ones I needed to take action on were: #4 - some of the internal links in our oldest blog posts were still linking to the http:// version, so I installed https://wordpress.org/plugins/ssl-insecure-content-fixer/ to automatically fix those hyperlinks site-wide. #6 - I updated a couple URLs in our Twitter bio and Facebook page. I can see how fixing these two issues could help improve our site's rankings, but I'm still doubtful that these two issue have caused our site to be completely unfindable for non-branded terms on search engines though. Would love to hear any other ideas people have!
