From a recent WP:VPT discussion, it was suggested to have the following added as an automatic "general fix" in AWB: changing the protocol for certain external links from HTTP to HTTPS, although only within citation templates. For now, this should include a number of Google services (e.g. Google Books, Google News, YouTube) and the Internet Archive (i.e. Wayback Machine). In essence, this should probably be some sort of RegEx feature that looks for `|url=http://books.google.[com|co.uk|ca|de|it|es|...]` and replaces it with `|url=https://books.google.com` (yes, the top-level domain switch is intentional here, since Google redirects from `.com` to a specific country version, and we should keep the links general). The same for Google News, YouTube as well as `http://archive.org` and `http://web.archive.org/` links. (For the latter, of course, the RegEx would have to find `|archiveurl=http://[web|wayback].archive.org/`)
