Does Ads On Your Page Slow Down Websites

by Jay | Posted on November 14th, 2022

We feel upset when webpages take a long time to load. We visit a different website that loads quicker than waiting for the page or the website to load. There might be a variety of explanations for why particular websites load quicker than others.

Publishers all across the web are placing more importance on site speed. Unfortunately, even the most experienced developers struggle to pinpoint why a website is slowing down and how to fix it. Popular site speed measurement tools frequently offer aggregate ratings and general recommendations, but they often lack the specifics or guidance required to implement effective adjustments.

Most websites and blogs make money through Google AdSense display advertisements; thus, by default, there are several ad units on each page. Although it may initially appear financially advantageous, a slow-loading website could cause fewer visits over time. If ad units are big, it takes longer for the website to load. The website load time increases with ad unit size and complexity.

How can you improve your website’s performance?

General page speed

Use a plugin and caching to downsize the scripts and code on your site.

Advanced Ads Pro specifically supports the Autoptimize plugin, and WP Rocket is actively used to test our cache-busting.

Use asynchronous ad codes

You can produce tags for asynchronous advertisements when creating AdSense ad units. This process gets rid of page load delays brought on by ads. When using asynchronous ad code, the browser processes the rest of the page before processing the AdSense code. Essentially, it indicates that the adverts load independently of the rest of the website. As a result, other parts of the website will still load even if you have a huge and complicated ad.

Improve image sizes

Ad photos should only be uploaded at the size you intend to utilize them.

Compressing an image locally or within your browser costs more than simply using a minified image file.

Cache-busting (advanced ads pro)

If you don’t require cache-busting for a particular placement, turn it off or use passive cache-busting.

Lazy load (advanced ads pro)

Certain advertising’ lazy loading can also aid with page performance optimization.

In the following lesson, you can discover how to install lazy loading for advertisements and how it could impact income and page performance.

Control the file size

Making sure that the file size of different files (such as photos, CSS, JS, etc.) does not exceed 60KB can help accelerate the page load on your website or blog. The lower the file size, the quicker it loads. Optimizing and reducing the number of photos on a website is wise. To resize or optimize the image, employ a powerful image editor. Alternatively, you might use a plugin to resize the images immediately.

Limit the ad units

To maximize income, we use numerous ad networks and place an excessive number of adverts on a single page. We occasionally overlook that the quantity of adverts slows down how quickly the page loads, deterring consumers from visiting. Analyzing the advertisements on your page is advised. Delete the ad if you know it is slowing down website load times to enhance user experience.

Turn off tracking (Tracking add-on)

AJAX tracking and other tracking methods used when Cache Busting is enabled can be performance-intensive.

Use Google Analytics tracking instead, or upgrade to the Frontend technique (introduced with Tracking 2.0), to fix this problem.

Frequently Asked Questions

Do Google ads slow page load?

Many websites and blogs make money through Google AdSense display advertisements; thus, there are several ad units per page by default. Although it may initially appear financially advantageous, a slow-loading website may cause fewer visits over time. If ad units are big, it takes longer for the website to load.

Why are Google ads slow?

Why do ads load slowly?

“Advertising often doubles the time a webpage spends loading. Page loading is frequently much longer when offensive ad quality concerns exist.” Due to the volume of queries necessary, Ad Lightning also discovered that advertising networks with huge advertisements took longer to serve ads to websites.

Why are my page loads so slow?

The most frequent cause of a website’s delay is many poorly optimized pictures. When loading, high-resolution images might use a lot of bandwidth. The size of your web page can be unnecessarily increased by uploading larger-sized pictures and downsizing them, leading your website to load slower.

Tools to find which ad unit is slowing down your website


To view a real comparison of how your website performs with advertisements active and removed, you can activate an ad blocker in GTMetrix testing. Sadly, this particular function is only accessible in the premium edition.


WebPagetest is extremely strong and the industry standard for web performance gurus. It gives diagnostic reports, runs page performance optimization tests, and more.

In addition to the ad networks, several elements add to sluggish page speeds and performance bottlenecks. Although plugins, bloated themes, and other components might be to blame, advertisements are typically the main cause of delayed page loads. It’s critical to control the ad units to optimize ad income and provide the maximum impressions without degrading the user experience. It is advised that you often monitor your website. It will enable you to locate and improve sluggish ad networks.


Always remember that increasing your page speed is a continual process, and benefits won’t appear overnight.

Conduct a site audit to identify the pages that slow down your loading time and fix them.
