Which Plugin Is Slowing Down Your WordPress Website? I’ve been using WordPress for a very long time and tested hundreds of WordPress plugins. Below is a list of slow loading plugins that will slow down your website. Note that I have personally tested the below plugins and your experience with these plugins my differ from my personal results with the below plugins so feel free to let me know. After getting rid of slow plugins on my blog. My blog now loads in under 2 seconds. The slow plugins like Contact Form 7 and Contextual Related Posts that I still use on my blog I use the Asset Clean Up plugin to trim the bloat and fat (unnecessary CSS/Javascript) from my site. Hot Tip: Your website's speed and loading time will become a huge ranking factor in 2021(Google said so themselves) so be sure to get your website ready when the Google algorithm hits in 2021. Unique/Great content will still dominate the serps though! so don't lose focus of that. It's just that Google will put heavy emphasis on the user experience and page loading times in conjunction with great content. So just imagine having keyword rich, SEO optimized pages along with a fast website = money in the bank! Anyways back to the slow plugins... that's why you are here right? You can see below my blog's loading time from using the GTmetrix tool along with my Google Page Speed Insight scores for both Desk top and Mobile users. (Removing bloated plugins was a huge factor.) 1. My GTmetrix Page Speed/Y Slow Scores: 99%/93% and fully load of 1.2 seconds. 2. My Desktop Page Speed Insights Scores 100 3. My Mobile Page Speed Insights Scores 94 Oh yes before I forget to tell you I also use the WP Rocket plugin on my blog that has also helped me achieve those fast load times and scores with my blog. (Note: it's a premium/paid plugin no free version, but Autoptimze plugin is a great free alternative to WP Rocket if you're strapped for cash.) List of 65 Slow Plugins I've tested...

If you’re using any of the plugins on the above list, either get rid of them or find a replacement. If it's a must use the Asset Clean Up plugin to strip unnecessary code from loading on your website post/pages. Is there any other slow plugins you've encountered? Let me know if there is a recommendation for me to replace Contact Form 7 and Contextual Related Post plugins with a lighter plugin then do let me know.
