Plugins and Scripts That Slow Down Your WordPress Website Load Time

Plugins and Scripts That Slow Down Your WordPress Website Load Time

Did you know that plugins and scripts can slow your sites down by over 300%? We recently discovered this when we analyzed a slow loading site from our new cluster in Australia!

When you add a plugin or 3rd party script on your WordPress site, whether it be a Google Analytics tag or a Facebook Like button, it directly impacts your load time.  I’ve seen a lot of people get frustrated with their WordPress load times over the years and it all (generally) is a result of loading 3rd party assets (unless they just have poor WordPress hosting).  

These problems are most commonly seen with advertising tags or ad networks loading many pixels on your site.  Some people choose to monetize their WordPress site by adding ads, which is a great way to make passive income.  However, these assets (images, videos, or tracking codes) have to be pulled from somewhere other than your site – this is where latency comes from. Latency is the time it takes a user to load an asset from your site into their browser.  Oftentimes, they’re at the mercy of the ad network’s connectivity. The same goes for every other asset loading. 

Recently, we discovered a perfect example of this on a site created on our new Australian cluster.  The customer was pulling assets from Facebook and it added half a second to the site’s load time! Our discovery on this was that Facebook doesn’t appear to have an Australian presence and the asset was being pulled from a U.S-based data center.  The load time was 3.8s and once the outside-loading assets were removed, the load time dropped to 1.0s, a 380% increase in performance!

There’s not a lot that can be done in these type of situations aside from removing the problematic assets.  Some ad networks may have options to load their ads last on the page, so at the very least your page renders quickly for the user.  There are also paid options out that can load those pesky assets last. It’s fairly easy to obtain this type of data using freely available tools like GTMetrix and  The goal should always be to render the page as quickly as possible in the user’s browser and some of that can be achieved by simply using a premium WordPress platform – it won’t relieve all of your page loading woes, but it will absolutely help.

It’s been nearly two decades since I started my journey from graphic design to digital marketing and product management. Those two decades have taken me across the country from Fort Myers, Florida to San Francisco. I have gone from owning my own agency to multiple senior executive roles at large public companies. It’s been my great fortune to work with a world-class team of digital marketing professionals; my hope is that they learned as much from me as I learned from them. Over my career, I have worked in both small business and Fortune 500 companies. I have had the honor of being a presenter for organizations like Microsoft, Intuit, Sage Software, RealPage, NARPM, NAA, and the Small Business Administration. Most recently I completed my first ebook, Infographics in Action, which teaches exactly how to create and market with infographics. Currently, I work in San Francisco and reside in the bay area with my wife and four children. Feel free to drop me a line, I would love to hear from you!
