PageSpeed Insights says my landing page has a score of 15 out of 100 for performance. This appears to be mostly because I need to “Eliminate render-blocking resources”. It’s loading a lot of CSS and Javascript from a few plugins I cannot uninstall.
It seems the main way to fix this is by installing even more plugins that make it so the CSS and Javascript download simultaneously with the HTML, instead of taking turns. However, many people say these plugins (like all plugins it seems) often break your website and cause other problems.
My question is what free plugins or one-time payment plugins (no subscriptions) do people recommend that will fix this. Or in the alternate, is there some manual code I can add.

This will delay all of your javascript until after the css loads. That’s going to massively drop the page weight of your site, which will make the perceived load time much, much faster.
You’re going to **need** to test this on a staging server first. Make sure you bug test the site thoroughly to make sure nothing breaks. If anything does, it means you have to find which javascript files you need to exclude to prevent the functionality or design from breaking.
This won’t solve your whole issue, but it’ll help.
For the best free option for a variety of other optimizations, asset cleanup is the go to.
Perfmatters has some additional functionality asset cleanup doesn’t and vice versa. I use them together.
Per year subscription, but all paid optimization plugins worth anything have subscription based pricing.
Perfmatters has a delay javascript feature as well, which I prefer to use in conjunction with WP Meteor. The remove unused css feature in perfmatters is absolutely a necessity if you want to fix the render blocking resources thing. Flyingpress and WP Rocket have that feature as well.
Those plugins will solve a majority of your issues. Again, make sure you test all your optimizations on staging first to make sure nothing breaks before you throw it live.
If you don’t have access to a staging server, create a backup and either restore it on instawp.io to test the changes or use something like or
