Best Speed Optimization Plugins

One of the best ways to ensure that your website does not come across as sloppy is caching. Other known methods, beside using speed optimization plugins, include reducing image sizes and minifying codes. Although these do not make a slow site automatically run faster, they work to reduce the delivery time of websites. In other words, the time it would take for users to access pages they search for would be cut down. Why is this?

Caching, for example, reduces the loading by drawing resources like JavaScript, CSS, images, and HTML to a temporary storage location from where these can be easily accessed when demanded. The other two methods mentioned above enhance your site speed by reducing the space taken up by codes and images.

Having seen some ways you can optimize your website speed, let us proceed to review some plugins that would be a great addition to your site for this purpose. But first, why do you need plugins to optimize your site speed when you can maneuver on your own?

Speed Optimization Plugins

Why You Need Speed Optimization Plugins on Your Site

Some general benefits of having plugins for optimal site speed on your website include;

  • Improved SERP rankings – Speed optimization is known to have an impact on the SEO of websites. This has to do with your site having users exiting your site almost immediately. This, of course, would be inevitable if users lose interest before they can access your content. By extension, having plugins that assist in optimizing the speed of said websites, reduces the bounce rates on your site and translates to better SERP rankings.

  • Effective caching – Certain speed optimization plugins can determine best what pages should or should not be cached. Not only does it make this decision, these plugins automatically take action.

  • Time effectiveness – As with other plugins, speed optimization plugins reduce the amount of work you would have to put in if you had to manually take steps towards freeing up space on your site's backend.

  • Storage – Using speed optimization plugins, you get to store cached objects for longer periods than stated by the web application rules.

With these few general importance of having speed optimization plugins in mind, let us consider some top WordPress plugins that are effective for site speed optimization.
