Over time though, they added, "we may decide to strengthen it, because we'd like to encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web".
Google suggests moving to a 2048-bit key certificate which, according to experts, won't be breakable for a foreseeable future. Also on the list are suggestions to remove any obstacles that could prevent spiders from crawling your site and removing NOINDEX where possible.
