Michael has a website and has learned that Google has changed the rules regarding SEO. Leo says that Google is always changing the rules in an effort to combat spam. Michael's analytics have dropped dramatically since then, though. Leo says that following the webmasters tools based on Google's analytics is really the best thing to do. Will using Java affect his SEO? Leo says no. Having an updated site map will improve his chances. Making his website "mobile responsive" will also be rewarded. Loading speeds are also key. Google wants his site to be mobile friendly and Google has a test in the webmaster tools to see if it is. That can really matter as well.
