How I Boosted My AdSense Earnings by 30% with 5 Simple Core Web Vitals Fixes
Hey everyone!
Let me tell you, I’ve been in the digital trenches for a while now, and if there’s one thing that keeps me up at night, it’s watching my hard-earned website traffic bounce away because of a slow-loading page.
And what’s worse?
Seeing that big, beautiful ad space sitting there, but not generating the revenue it should.
I used to think my AdSense problems were just about traffic volume, but boy, was I wrong.
It all came down to something Google has been shouting about from the rooftops: **Core Web Vitals**.
You’ve probably heard the term thrown around.
Maybe you’ve even checked your scores and winced a little.
I know I did.
My site was a mess—a veritable digital snail.
My **Largest Contentful Paint (LCP)** was atrocious, my **First Input Delay (FID)** felt like an eternity, and my **Cumulative Layout Shift (CLS)**… well, let’s just say it was a wild ride of content jumping around.
AdSense, it turns out, is deeply intertwined with these metrics.
A slow site with bad **Core Web Vitals** doesn’t just annoy your visitors; it actively hurts your ad revenue.
Think about it.
If a user clicks on your site and has to wait forever for the main content to appear, they’re gone.
And if the ads load in a way that shifts the page around, they might accidentally click on an ad they didn’t mean to, which leads to a bad user experience and, eventually, lower ad quality and revenue for you.
This isn't just theory; it's what I experienced firsthand.
I was pulling my hair out, trying to figure out why my traffic was decent but my earnings were stuck in the mud.
So, I rolled up my sleeves and dove deep into the world of **Core Web Vitals** and **AdSense optimization**.
And I’m not exaggerating when I say the results were nothing short of a miracle.
Within a couple of months of implementing these changes, I saw my AdSense revenue jump by over 30%.
It was like finding a secret key to unlock a treasure chest.
And here's the best part: these aren't complex, developer-level fixes.
Most of them are things you can do yourself with a little bit of time and effort.
I’m going to share with you the exact steps I took, the "A-ha!" moments I had, and the resources that helped me along the way.
This isn't some generic guide.
This is a battle-tested roadmap from someone who’s been where you are right now.
Are you ready to stop leaving money on the table?
Let's dive in.

Fixing LCP: Make Your Content Pop!
Let's start with the big one: **Largest Contentful Paint (LCP)**.
This metric measures how quickly the main content of your page loads.
Think of it like the moment the curtain goes up on a stage play.
You want that curtain to go up fast, so your audience (the user) can get to the good stuff.
For most pages, the LCP element is a hero image, a big block of text, or a video.
If this element takes too long to load, Google sees it as a bad user experience, and your **Core Web Vitals** score tanks.
And guess what?
So does your AdSense revenue.
Why?
Because if the user leaves before the content (and the ads!) even loads, you've lost the impression and the potential for a click.
It’s like baking a delicious cake but taking so long to bring it out of the oven that your guests get bored and leave before they even get a whiff.
Here’s what I did to slash my LCP time:
1. Image Optimization is Non-Negotiable
Images are often the biggest culprit for a slow LCP.
I was shocked at how large some of my image files were.
I mean, we’re talking about high-resolution photos that were completely unnecessary for a web page.
My first step was to compress every single image on my site.
I used tools like TinyPNG or Imagify.
These tools can reduce file size by 50% or more without any noticeable loss in quality.
I also started using **next-gen formats** like WebP.
They are smaller and load faster than traditional JPEGs and PNGs.
You can easily convert your images to WebP using various online tools or plugins.
This was probably the single most impactful change I made.
The difference in load time was immediate and dramatic.
2. Implement Lazy Loading for Images and Ads
This is a game-changer.
**Lazy loading** means that images and ad units don’t load until the user scrolls down and they are about to come into the viewport.
This way, the browser doesn't waste time and resources loading things that the user can’t even see yet.
For images, it’s a simple HTML attribute: loading="lazy".
Most modern browsers support this natively.
For AdSense, you can use the same principle.
Instead of having all ad units load at once, you can set them to load asynchronously or even with a slight delay.
This prioritizes your content and improves LCP.
If you're on WordPress, there are great plugins that handle this for you automatically.
Trust me, this simple tweak will make your site feel incredibly snappy.
3. Optimize Your Server and Hosting
Sometimes, the problem isn’t your site’s code, but the foundation it’s built on.
I realized my cheap shared hosting was a bottleneck.
It was like trying to run a marathon in a pair of flip-flops.
I upgraded to a better, more reliable hosting provider with solid-state drives (SSDs) and a good server response time.
This isn't always cheap, but if you’re serious about your website and your AdSense revenue, it’s a necessary investment.
It's the equivalent of upgrading from a rusty old car to a sports car—you just get there faster and more efficiently.

Tackling FID: The Need for Speed
Next up is **First Input Delay (FID)**.
This metric measures the time from when a user first interacts with your page (like clicking a link or a button) to the time the browser is actually able to respond to that interaction.
A good analogy for this is walking into a crowded coffee shop and trying to order.
If the barista is busy with a thousand other tasks and ignores you for a few minutes, that’s a bad FID.
You get frustrated and might just walk out.
On your website, a high FID can be caused by heavy JavaScript execution or third-party scripts, like those from AdSense.
Yes, AdSense itself can sometimes be a culprit here.
But don't worry, there are ways to manage it without killing your revenue.
My biggest realization was that the problem wasn't the ad itself, but how and when it was loaded.
Here's how I cleaned up my FID:
1. Defer Non-Critical JavaScript
I had a ton of JavaScript files loading at the top of my page.
These were scripts for analytics, social media sharing buttons, and a bunch of other things that didn't need to load immediately for the user to interact with the page.
I learned to **defer** these scripts.
This means telling the browser, "Hey, don't worry about this script right now.
Load the important stuff first, and then come back to this later."
You can do this by adding the defer attribute to your script tags.
For example: .
This small change made a huge difference in my FID score.
2. Break Up Long Tasks
Sometimes, a single script can take a long time to execute, blocking the main thread and causing a high FID.
I identified some of these "long tasks" in my performance reports and worked on breaking them up into smaller, more manageable chunks.
This is a bit more technical, but if you’re using third-party scripts, especially those from ad networks, you can often find ways to optimize their loading or even use a tag manager to control when they fire.
The goal is to give the browser's main thread a chance to breathe and respond to user input without getting bogged down.
This also applies to how you handle your AdSense code.
Instead of a single, massive script, consider using a tag manager to load specific ad units when they are needed, rather than all at once.
This is where the AdSense async script comes in handy.
The async attribute tells the browser to download the script while the page is still loading, but not to block the page from rendering.
It’s a lifesaver for FID.
For more on FID and how to fix it, I found this detailed guide from an expert particularly helpful:
Defeating CLS: No More Ad-Induced Page Jumps
This one is a personal pet peeve of mine: **Cumulative Layout Shift (CLS)**.
This metric measures how much your page's content shifts around unexpectedly while it’s loading.
You know the feeling, right?
You’re about to click a link, and then an ad loads and pushes everything down, and you accidentally click on the ad instead.
It’s infuriating.
It's like a game of whack-a-mole, but with your website's layout.
And guess what?
Google hates it too.
A high CLS score tells Google that your site is unstable and provides a terrible user experience.
And AdSense ads are often a major source of CLS.
Because they are loaded asynchronously, the ad container is often empty until the ad itself loads.
When the ad finally appears, it forces the surrounding content to shift.
This is a classic problem, but the fix is surprisingly simple.
1. Reserve Space for Your Ads
The single most important thing you can do to fix CLS caused by AdSense is to reserve the necessary space for your ad units.
You need to tell the browser how much space to set aside for the ad before it even loads.
I did this by wrapping my ad unit code in a `
For example, if I was going to display a 300x250 banner ad, I’d create a div with those dimensions.
This way, when the ad loads, it fills that space without pushing anything else around.
It’s like putting a placeholder on your desk for a coffee mug.
Even if the mug isn’t there yet, you know exactly where it’s going, so you don’t have to rearrange all your papers later.
For responsive ads, it's a bit trickier, but you can use CSS to set an aspect ratio placeholder.
This ensures the space is reserved correctly on different screen sizes.
2. Avoid Injecting Ads Above Existing Content
I used to think placing an ad right at the top of my content would be a great way to get impressions.
I was wrong.
This is a recipe for a terrible CLS score.
The best practice is to place ads in locations that won’t cause a shift.
Think of places between paragraphs, at the end of a section, or in the sidebar.
The user is expecting these elements to appear there, so the shift is either minimal or non-existent.
This is about finding the sweet spot between visibility and user experience.
It’s a balancing act, and for me, a slightly lower ad position with a better **Core Web Vitals** score was a much better trade-off.
My AdSense earnings increased because my traffic stayed on the page longer and Google was happy with my site's performance.

Smart Ad Placement: The Art of the Ad and Content Dance
This is where all the previous tips come together.
Optimizing your **Core Web Vitals** is one half of the equation; the other half is making sure your ads are placed in a way that maximizes revenue without sacrificing user experience.
It’s a delicate dance, and you have to be the choreographer.
This isn't about slapping as many ads on the page as possible.
That's the rookie mistake I made at the beginning.
The goal is to find the perfect balance that keeps your visitors happy and your wallet full.
1. Use In-Content Ads Strategically
In-content ads, when done right, are incredibly effective.
They are highly visible and don't feel as intrusive as a pop-up.
I started placing my in-content ads after the first two or three paragraphs and then spaced them out every few hundred words.
This ensures that the user has a chance to get hooked on your content before they see the first ad.
It feels natural and less jarring.
And because the user is already engaged, they are more likely to stay on the page and interact with the ad.
I also made sure to use responsive ad units, which automatically adjust to the screen size.
This is a must-have in a mobile-first world.
2. Anchor Ads and Vignette Ads: Use with Caution
**Anchor ads** and **vignette ads** can be a great source of revenue, but you have to use them wisely.
**Anchor ads** are those sticky ads that stay at the bottom of the screen.
They can be very profitable, but they can also be annoying.
**Vignette ads** are those full-screen ads that pop up between page views.
They are great for monetization, but they can be a poor user experience.
My advice is to test them and see how your audience reacts.
Google provides tools to control the frequency of these ads, so you can find a balance that works for you and your visitors.
It’s like adding seasoning to a dish.
A little bit makes it delicious, but too much can ruin the whole meal.
Remember, the goal is not to get one-time clicks.
The goal is to build a loyal audience that keeps coming back to your site.
Happy users mean more page views, and more page views mean more AdSense revenue.
It's a virtuous cycle.
FAQ Section: Your Burning Questions Answered
Q1: What are Core Web Vitals and why should I care?
**Core Web Vitals** are a set of three specific metrics that Google uses to measure a website’s user experience: **LCP (Largest Contentful Paint)**, **FID (First Input Delay)**, and **CLS (Cumulative Layout Shift)**.
You should care because they are a key ranking factor for Google SEO.
A good score can improve your search rankings, and a poor score can hurt them.
Beyond SEO, a good **Core Web Vitals** score translates directly to a better user experience, which means lower bounce rates, more engaged visitors, and ultimately, higher ad revenue.
Q2: Can AdSense hurt my Core Web Vitals?
Yes, it can.
AdSense code is a third-party script, and if not handled correctly, it can negatively impact your **LCP** (by slowing down the loading of your main content), your **FID** (by blocking the main thread), and especially your **CLS** (by causing content to shift when ads load).
However, by using the strategies outlined in this post—like lazy loading, reserving ad space, and placing ads strategically—you can mitigate these negative effects and optimize your site for both user experience and revenue.
Q3: How do I check my Core Web Vitals score?
The best way is to use Google's own tools.
My go-to is **PageSpeed Insights**.
Just type in your website URL, and it will give you a detailed report on your **Core Web Vitals** scores and provide actionable recommendations for improvement.
I also highly recommend using **Google Search Console**.
It has a dedicated **Core Web Vitals** report that shows you how your site is performing for real users in the wild, which is even more important than the lab data from PageSpeed Insights.
It's like getting a report card from Google itself.
Final Thoughts & Key Takeaways
Optimizing your AdSense revenue isn't just about getting more traffic.
It's about creating a better experience for the traffic you already have.
By focusing on **Core Web Vitals**—by making your site fast, responsive, and stable—you're not just pleasing the Google algorithm.
You're pleasing your users.
And when your users are happy, your AdSense earnings will follow.
The journey to a better **Core Web Vitals** score can feel overwhelming at first, but I promise you, it's worth it.
Start with the low-hanging fruit: optimize your images, implement lazy loading, and reserve space for your ads.
Then, tackle the more technical stuff.
Don't be afraid to experiment and test.
Remember, every website is a little different, so what works for me might need to be tweaked for your site.
And don’t forget to check your performance regularly.
I like to think of it as a constant process of tweaking and refining, like a chef perfecting a recipe.
If you can make your site load in the blink of an eye, and if you can make your ads appear without a hiccup, you’ll be on your way to a site that not only ranks well but also earns well.
Trust me, the feeling of seeing your revenue climb, knowing you’ve done it the right way, is one of the best feelings in the world.
Now, go out there and make your site a speed demon!
