8 Plugins to improve Page Speed and Performance

Websites should always perform at an optimal level. Thatís why boosting your site performance is no longer an option. Itís a necessity. Fortunately, WordPress users have plugins that can keep their site running smoothly.

Why is my website so slow?

Some sites will always be slower than others. If your WordPress site is unbearably slow, however, it could be due to one of the following reasons:

  • Bloated plugins ñ Some plugins are so big, they slow down site performance.
  • Bad theme ñ Poorly coded themes affect site speed too. Only use the best WordPress blog themes.
  • Image files ñ You should lower the file size of big images.
  • Poor site hosting ñ Some hosting companies provide lousy service.
  • External scripts ñ Ads, font loaders, and other external scripts impact site speed.

Improving site performance

How does one improve site performance? Google penalizes slow websites by ranking them lower in search results. And as of July 2018, Google will use page speed as a ranking factor for mobile search. Pages that ìdeliver the slowest experience to usersî will be impacted by the update.

In a survey quoted by Skilled.co, it states that 47% of customers expect websites to load within two seconds. 64% of smartphone users expect sites to load within four seconds. While other factors like internet speed are at play, users expect sites to load at reasonable speeds.

The same article mentions that 79% of customers who are unhappy with page load times are less likely to buy from you again. It causes hesitation from repeat buyers.

That said, your main goal should be to address site speed issues. There are a number of WordPress speed plugins that can help you achieve better load times.

There are different ways to approach this. You can use caching plugins to let browsers load sites faster. There are also plugins that help with image compression. There are also tools that combine JS, HTML, and CSS. This process is referred to as minifying.

Before you start, you should evaluate your site. That way, youíll be able to identify problem areas you need to address. You can use Google PageSpeed Insights to start.

Bonus: Non-plugin solutions

Some site speed issues canít be resolved through WordPress speed plugins. But that does not mean you canít do anything about them.

  • Change WordPress hosting ñ If youíre using a shared hosting plan, consider upgrading to a WordPress hosting plan.
  • iFrames ñ These are HTML documents that are embedded inside another HTML. YouTube videos use this technology. These can slow your site down. Limit your use of iFrame.
  • Remove 404 errors ñ Errors can also contribute to slow speeds. Remove links that are no longer working. Also, limit redirects.
  • Update your code ñ Your code should display CSS first. JavaScript should be at the bottom of the page. JS loads slower than CSS. Use shorthand coding to clean up your code. Use Google Tag Manager to compress all your marketing tags into one line of code.
  • Donít install too many plugins ñ Limit the number of plugins you install. Donít have more than one analytics tool, for example.

Final words

Of the WordPress caching plugins mentioned, W3 Total Cache is the most trusted one. Itís used by big brands such as AT&T and Mashable. It has over 2,700 5-star ratings and over 1 million active installations. Itís tried and tested. It gets updated on a regular basis.
