For a solution to be worth it, it has to yield results. 

In this article, we’re going to discuss NitroPack’s impact on the three most important fronts:

• Page speed tests 
• Core Web Vitals
• SEO

But we won’t just talk about how NitroPack works. You can see a list of features on our website. 

Every statement we made in the following lines is backed by real-world data, so you know what results to expect after installing our product. 

Let’s get started! 

NitroPack’s Impact on Page Speed Tests and Scores

Since we launched NitroPack in 2019, users have expressed all kinds of emotions after seeing their page speed score going from bad to excellent. You may stumble across statements and questions like:

• “How can NitroPack achieve so much better results than other solutions?”
• “The results I got with NitroPack are too good to be true.”
• “NitroPack works like magic!”

But the truth is – there’s nothing magical about NitroPack.

We worked hard to analyze how people were speeding their websites, identified the pros and cons of it, and got down to building a solution that fixes the cons and multiplies the pros. 

And the end result was NitroPack. 

But getting back to the question at hand: 

How can our users achieve 90+ PSI scores after installing NitroPack? 

Here’s how:

• NitroPack’s an all-in-one solution meaning you don’t have to install tons of plugins that will bloat your site’s code.
• NitroPack uses a one-of-a-kind algorithm for loading resources, delaying them until user interaction and utilizing modern CPU’s multi-core architecture.
• NitroPack includes a complete image optimization suite, including image compression, adaptive sizing, and image lazy loading.
• NitroPack applies font optimizations and is the only web performance tool offering a font subsetting feature.
• Combining all of the code, image, and font optimizations with a built-in CDN from Cloudflare, the results do not disappoint. 

In a nutshell:

We’ve replaced the need to install 10 different plugins to optimize your site’s speed with a single all-in-one solution that constantly integrates cutting-edge optimization techniques for future-proof results. 
 

What page speed score improvements can you expect after installing NitroPack?

No matter how advanced NitroPack gets in the background, at the end of the day, you want a site speed solution for the results you’ll get. 

Here are a couple of examples of companies and the results they achieved after adding NitroPack to their tech stack:

1. Mikalsen Utvikling – A Norwegian digital marketing agency

Before NitroPack, Mikalsen Utvikling had been using all kinds of different web performance solutions that got them PSI scores between 40-60. 

After trying NitroPack’s free plan, they were stunned by the immediate boost. 

They went from bad to excellent instantly:

“Through the free trial version, we had the chance to experience NitroPack’s immense impact on site performance ourselves. That made the decision to make a full transition free of concerns.”

— Mikalsen Utvikling

2. By Gamers For Gamers (BGFG) – A media publisher

BFGF is a UK media publisher that had a similar experience to Mikalsen Utvikling’s.

As their traffic grew significantly, they sought a reliable site speed solution to guarantee consistent results. 

After testing NitroPack’s free plan, they were positively surprised to see their scores jump into the 90’s:

“I signed up for a free account on NitroPack, then things started to get really interesting! No-fuss setup, and once the page was optimized, that scores jumped into the high 90’s!”

— BGFG

By applying some image optimizations and reducing the impact of third-party scripts, NitroPack managed to improve their PSI scores:

And these are just a couple of success stories out of all 250,000+ websites we optimize. However, seeing is believing. Test what NitroPack can do for your site speed for free.

NitroPack’s Impact on Core Web Vitals

Every solution/plugin you add to your website has to have a real-world impact.

Real-world impact?

Yes. Like in SEO, installing a plugin that flags your issues is not enough. It has to also boost your site’s rankings and, ultimately – your traffic. 

In terms of web performance, the metrics that measure how your site performs in the real world are Core Web Vitals. They help you evaluate how your visitors experience your website.

And here comes the harsh truth:

You can have a 90+ PSI score but fail your Core Web Vitals. 

In other words, a 90+ score isn’t enough. You need both to be truly competitive.

With NitroPack, you get a solution that improves Core Web Vitals while boosting your page speed scores. 

Here’s how we optimize your website for each metric:

1. Largest Contentful Paint (LCP)

Largest Contentful Paint measures the loading time of the largest visual element of a site.

It’s proven that LCP is the metric website owners struggle with the most. In fact, the latest Chrome User Experience Report (CrUX) shows that only 66.7% of origins had good LCP. 

The reason for that is there are a lot of moving parts when it comes to optimizing LCP. 

Fortunately, with NitroPack, all you have to do is add it to your website, and it starts applying the necessary optimizations оn autopilot:

• Reduce unused CSS (RUCSS);
• Image lazy loading;
• JavaScript lazy loading;
• Critical CSS;
• Code minification and compression;
• Lossy and lossless image compression;
• Preemptive image sizing;
• WebP conversion.

2. Interaction to Next Paint (INP)

Interaction to Next Paint (INP) measures how fast your site becomes interactive.

To speed up the process, you need to unblock the main thread. 

This is where NitroPack’s advanced resource loader comes into play:

• Our service delays the loading of non-critical resources until user interaction is detected.
• Our proprietary resource loader rearranges how resources are fed to the main thread.
• NitroPack applies code minification and compression to your JavaScript and CSS files.

As a result, your site’s main thread is unblocked, it becomes interactive immediately, and your visitors have an excellent experience.

3. Cumulative Layout Shift (CLS)

Cumulative Layout Shift (CLS) measures how much unexpected layout shifts affect the user experience on a page.

There are three main reasons for unexpected layout shifts to occur:

• Images and videos with no dimensions (width and height attributes);
• Ads, embeds, and iFrames without reserved space;
• Web fonts causing flashes of unstyled or invisible text – FOUT and FOIT.

NitroPack fixes all of them with:

• Preemptive image sizing. NitroPack solves the problem of missing width and height attributes without adding them. This speeds up rendering and reduces layout shifts.
• Adaptive image sizing. It makes sure that images match and don’t overflow their containers.
• Font subsetting. NitroPack removes your font’s unused glyphs. Hence, font files are generally much smaller, and the browser can load them almost instantly. 

Can you expect to see Core Web Vitals improvements after installing NitroPack? 

Yes, you can. 

But we said that we’d back every statement with data, so here it is:

1. The Core Web Vitals Technology Report ranks NitroPack as the #1 site speed solution 

The Core Web Vitals Technology Report was created by Google’s engineer Rick Viscomi. The report offers an overview of how 2000+ technologies perform in terms of Google’s Core Web Vitals.

Compared to other popular web performance plugins, NitroPack is the clear leader:

But the above results come from the CrUX, which means that it includes only sites with 1000+ visits. 

What about the ones with fewer than 1000 visits?

2. NitroPack’s Telemetry Report – 69.91% of all websites pass their CWV

Our Telemetry report measures the Core Web Vitals pass rate for all websites optimized by NitroPack, regardless of the number of visits. 

Our data shows that 69.91% of all NitroPack-optimized websites pass their Core Web Vitals. 

For comparison, according to the latest CrUX report, only 52.1% of origins (with 1000 visits or more) had good LCP, INP, and CLS. 

3. BionicWP Improved Their Core Web Vitals Pass Rate from 31% to 88%

BionicWP offers a managed WordPress platform for more than 2000 websites. Without NitroPack, only 31.74% passed their Core Web Vitals.

With NitroPack installed, the percentage jumped to 88.14%.

“People are happy with the results that NitroPack provides. You can see a lot of our testimonials talk about the speed results we have been able to get. NitroPack is also easy for our team to use across 2,000+ websites, making it one of the best scalable options out there for speed.”

NitroPack’s Impact on SEO

Google has repeatedly said that a fast site helps you rank better. 

It’s been more than 12 years since Google started measuring the speed of websites and using that in their ranking algorithms.

Google launched the “Speed Update” in 2018, making page speed a ranking factor for mobile searches.

In 2021, the Page Experience Algorithm and the Core Web Vitals were introduced, cementing the notion that Google cares about site speed and user experience when building the SERP.

So when it comes to ranking, having a fast website is a great boost. And there’s no better way to do it than using NitroPack. 

Here’s why:

NitroPack applies optimizations all across the board.

Unlike other solutions that specialize in optimizing a certain area of your site (e.g., images), NitroPack has a holistic approach that takes care of all your resources, boosting both speed and user experience.

As a result, it will boost your ranking, but also:

• Increase in traffic
• Decrease in bounce rates
• Increase in conversions

Should You Install NitroPack? 

At the end of the day, there is no risk in installing NitroPack. 

You can test it for free.

On top of that, NitroPack works on copies of your site’s files. It doesn’t change your original code files. 

In other words, if you decide to pause or stop using our service, all you have to do is click a button. After that, your website reverts to its original state.

There is nothing to lose and a lot to gain:

• 90+ PSI score 
• Passed Core Web Vitals
• Improved UX
• Conversion rates boost

Now that’s what we call a great deal!
