Gravatar is one of the top software products of Automatic. It is used on 1000s of WordPress content management powered blogs. With this service, commentators are allowed to add their profile image that will appear alongside their comment on WordPress blogs. Gravatar is useful in many ways. It can increase user engagement on sites, and it saves a little bit of bandwidth because the commentator’s image will be served from Gravatar servers. It will also attract more comments on your blog.
Gravatar is a free service. Thus, anyone can create an account on this site. Although it is a very useful online tool, Gravatar comes with a few disadvantages. It can affect page load time of your blog if the Gravatar server is down/facing some issues. If one of your WordPress posts has over 100 comments, the page load time will be adversely affected because 100 image requests will be made to Gravatar servers. Google considers loading time of a site as a ranking factor. It will be soon rolling out an update to improve rankings of a mobile friendly site and a page with very high loading time is not mobile friendly. One more problem associated with this online tool is that when you test your website speed with tools like Google page speed insights, GTMetrix, you’ll be recommended to remove Gravatar redirect chain. The problems stated above can be easily fixed with a WordPress plugin called FV Gravatar cache.
