Google’s new algorithm puts more and more focus on mobile users and their needs. It has become critical to make sure that your website is mobile friendly and that it loads faster than ever. In order to make sure that your website matches Google’s requirements, Google has released a very useful tool: https://testmysite.thinkwithgoogle.com/.
The tool will provide a score for mobile friendliness, mobile speed and desktop speed. You can then get a detailed report that will provide actionable items to increase your score.
Moving forward, if you are planning a website redesign, you should make sure that your developer is using this tool to fully optimize your site for Google. Otherwise, you may end up not ranking on your search terms no matter how many blog posts you write or social likes you get.
