To improve your Google ranking (i.e. to have your website appear higher in a Google search), we recommend you to install an SEO WordPress plugin.
SEO (or Search Engine Optimisation) is the process of improving the volume or quality of traffic to your website from search engines like Google, etc. via “organic” or unpaid search result.

SEO is an important part of any website. To ensure that your website/blog posts are getting maximum results, you need to optimize them using an SEO plugin. While these types of plugins don’t automatically boost SEO, they do help you make the most of your website/blog posts.

There are a number of different plugins available for working on SEO, some are available for free while others have paid-for options. To pick a plugin suitable for your website, please visit the official WordPress Plugin website.
