Welcome to the Q&A Forum

I received an unsolicited SEO report for one of my sites. My site was faulted for not having IP canonicalization set up. I reviewed this carefully. My site runs on Apache, is https and is on a dedicated IP. The mod rewrite rules for Apache all deal with the http version of the site. When I type my site's IP into a browser, I get the the https version, but with a unsecure cert warning as the certificate does not include the IP.

Should I implement the http IP canonicalization rule. Another rewrite rule would then redirect the request to the https version?

Thanks for the advice

The Moz page grader identified several pages where the only problem is the length of the URL, above 75 characters. The site uses uses the www. prefix, and has for years, since 2001. Is it worth dropping the www. and doing a redirect to https://domainname.com to gain the 4 characters
