WordPress Plug-Ins that Slow Your Site Down

website wordpress plug-in speed test results

One of the more pressing issues in WordPress development is website speed in general.  Google has made it very clear that website speed is something they value very much when determining where your site gets ranked. So there exists a dichotomy of wanting a fast website but one with bells and whistles as well.

The simple fact is that plug-ins slow your site down. But which plug-ins are the worst offenders? In this article I am going to display what I found when I disabled all of  my plug-ins and then reactivated them one-by-one. I used Google’s speed test to determine results. Remember, there are two separate speed tests, one for mobile and one for desktop.

I activated the plug-ins one-by-one starting with the ones I know don’t affect website speed all that much first. I activate the heavier plug-ins last.

Conclusion

This may seem like a bunch of mumbo-jumbo to the layperson but to anyone who has added/deleted plug-ins in an effort to speed up their site knows how pertinent this information really is.

The use of plug-ins is a balancing act which means you should use the plug-ins you only absolutely need or risk slowing down your website and affecting your Google ranking.
