Why Speed Up Your Site?
Having a fast website is a must. Why?
First of all, users will bounce away from a website that’s slow to load. Instead of waiting for the page to load, they’ll just click the back arrow and find a site that’s faster. In fact, according to Portent, website conversion rates drop by an average of 4.42% with each additional second of load time (between seconds 0-5).
If you’re a retailer, here’s an important stat to know: According to Unbounce, nearly 70% of consumers admit that page speed impacts their willingness to buy from an online retailer.
In addition, Google’s 2021 Page Experience Update will give fast pages a ranking boost in search results.
If you want your site to rank well and perform well, speed is essential.
How to Test Site Speed
Alright, so we’ve confirmed that website speed is incredibly important, but how do you test it?
There are a bunch of speed test tools out there. The easiest way to find your site speed, though, is to use MonsterInsights.
MonsterInsights is the best Google Analytics WordPress plugin. It helps set up analytics without editing code at all! You can also use the plugin to add advanced tracking features like eCommerce tracking, file downloads, form conversion tracking, and more in just a few clicks.
To start, download and install the MonsterInsights plugin at the Plus license level or above. Next, connect Google Analytics to WordPress using the setup wizard. For more details, refer to our tutorial on how to add Google Analytics to your WordPress site.
Once you have it set up, navigate to Insights » Reports » Site Speed.
Here, you’ll see your overall score, loading time by seconds, and a “How to Improve” section for your developer to use. You can use the toggle in the upper left to look at your mobile speed or your desktop speed.
Alternately, you can use PageSpeed Insights by Google.
Using this tool is simple: Just paste your URL into the tool and click Analyze.
The tool will then give you an overall number between 1 and 100 to rate your page’s speed, and will break down what it is about your speed that needs improvement (you can send this information to your developer).
Also, make sure to toggle to Desktop in the upper left corner to see your speed there too. The tool will show your Mobile speed first by default.
What Does a WordPress Cache Plugin Do?
You’ve heard that a cache plugin can speed up your site, but how does it work? We’ll break it down into simple terms for you.
When your website loads, there are a whole bunch of different parts that load. Your images, the code that tells your website how to look, the code that tells your website how to function, and your on-page content are a few of the bits and pieces that have to load.
Depending on how big all those pieces are, it can take some time for them all to finish loading, adding to the overall time your site takes.
A cache plugin optimizes some of the loading processes in a few different ways, but mostly, it makes a copy of your page the first time it loads, then uses that copy to show users that visit after. This way, the whole site doesn’t have to load every single time. It puts a copy of the page into your “cache,” which is just a fancy way of saying storage space.
Some WordPress cache plugins go beyond simple caching to give you some extra settings that’ll speed up your site even more.
Let’s dive into our list of the top WordPress cache plugins!
