These terms (the above terminology) might be overwhelming for you at first, especially if you’re not a tech guy.
But, don’t worry about that!
I am going to explain everything step by step in simple words. So that you can proceed at your pace and implement the methods to fix ‘Eliminate render-blocking resources’ on your website/blog.
Let’s try to put this a perspective with Google PageSpeed Insights warning and recommendation.
When you test, a website using Google Pagespeed Insights Tool, you get some warnings and recommendations to fix those warnings/errors.
The PageSpeed Insights (PSI) text for render-blocking resources says,
Eliminate render-blocking resources.
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
And this needs to be fixed.
As Google PageSpeed Insights (PSI) recommendation says you should deliver critical JS inline and defer all non-critical JS.
What does this mean?
Let’s break that down by terminology.
Inline Delivery: Inline delivery refers to load a resource (in this case JS) within the HTML code instead of calling/importing that separately.

How does JS Affect the SiteSpeed?
Wondering, why is that?
Because when the web browser comes across a script, it executes the script first before continue to load HTML that includes the content users are looking for.
Why not defer this heavier task of JS execution so that critical rendering path remain uninterrupted, right?
Pagespeed: is now a Ranking Factor
Site speed has already become a ranking signal.
About a decade ago Google announced 2 site speed a ranking signal in an official blog post on Google Webmaster Central Blog.
In another blog post published on Official Webmaster Central Blog in 2018, they revealed 3 that Google started using page speed as a ranking factor in mobile search ranking.
Since Google had declared pagespeed a factor in search result rankings for desktop and mobile. Therefore, site speed optimization has become a significant aspect of technical SEO.
User Experience: decides Your Site’s Success
Speed is matters, users do not like slow loading websites. In fact, studies show that the users leave a slow loading site early and move on.
As I mentioned above, however, the parser (browser) gives priority to execute the scripts over parsing the HTML.
And by making your site load faster, you also improve your search ranking on desktop as well as mobile.

You might be thinking, but why?
First of all, functions.php is an important theme file. That means you might end up breaking your site easily if anything went wrong with the editing of functions.php file.
How to Edit functions.php File Safely
I always recommend using a child theme in WordPress in order to avoid code editing mess.
Because while editing the code, even if you miss a single comma (,) semicolon (;) or any other symbol/syntax, your website will break completely or partially. And you have to make extra efforts to recover the site.
If you’re not using a child them, learn how to use a child theme in WordPress and its benefits.
Take a complete backup before making any changes to code.
I assume that you’re using a child theme. If you’re not, first create and activate a child theme to any trouble because of theme files editing.
- Go to your WordPress Dashboard > Appearance > Theme Editor
- Select/open functions.php file (of child theme) from theme files.
- Paste the code snippet given below at the end of functions.php file.
- You can specify JS files to exclude from defer in array (‘jquery.js’).
- Finally, click Update File to save changes. That’s all.
The code snippet to be pasted in functions.php file.
