Don't forget your website has to meet the new google compliance rules
1) mobile responsive via template
2) google mobile first rule (pc versions of websites are no longer indexed)
3) monitor resolutions (must scale via template)
4) you must have a google webmaster account, and it must be properly configured.
5) You have to manually submit to the new google mobile (smartphone) index via fetch and render. Non-compliance will incur search engine listing penalties. It is reported that if you don't do this, your site will not be in the new search index at all. Compliant websites will show up first.
Many customers are getting notices from the hosting companies about upgrading. Your notice may look something like this:
"We have detected that your server is using PHP 5.3 which is obsolete and no longer receives official security updates by its developers. The Joomla! Project / Wordpress / Drupal / Magento recommends upgrading your site to PHP 7.2 or later which will receive security updates at least until 2019-12-01. Please ask your host to make PHP 7.2 or a later version the default version for your site. If your host is already PHP 7.2 ready please enable PHP 7.2 on your site's root and 'administrator' directories – typically you can do this yourself through a tool in your hosting control panel, but it's best to ask your developer if you are unsure."
