Float AdSense And Display Ad Banner on Left or Right Side of Your Blog: Modern, Responsive, and Mobile-Friendly Ad Widget
Every ambitious blogger and website owner leveraging platforms like Google AdSense or other high-paying third-party advertising solutions shares a common goal: to significantly maximize ad exposure and boost passive income. In the competitive digital landscape, static banner ads often fall short. This is where the strategic advantage of floating AdSense ads comes into play. These dynamic, on-screen advertising units represent a powerful and highly profitable method to supercharge your ad revenue, as they are ingeniously designed to automatically scroll with your users, ensuring persistent visibility. This constant presence naturally leads to a dramatic increase in ad impressions, fostering more valuable ad clicks, and ultimately, substantial increased earnings for publishers.
Specifically, integrating floating ad widgets on the left or right side of your blog can be a game-changer for enhancing ad visibility and driving a significant revenue uplift. However, success hinges on a thoughtful and technically sound implementation that respects user experience. This comprehensive tutorial will guide you through the precise steps to add a fully responsive, SEO-friendly, and accessible floating ad widget to your Blogger or any HTML-based blog. You'll gain insights into implementing clean code, utilizing modern SVG icons for a crisp look, and following clear, step-by-step instructions on customization to perfectly align with your site's aesthetic and user experience goals. This isn't just about placing advertisements; it's about optimizing your entire blog monetization strategy to its fullest potential, ensuring every visit contributes meaningfully to your earnings.
Are you currently concerned about your existing ad network's performance, perhaps seeing lower-than-expected CPM or CTR and struggling with your overall online revenue generation? Many publishers find themselves in this predicament, questioning the effectiveness of their current advertising setup.
The truth is, many online publishers don't generate the income they expect from their chosen ad networks. This isn't necessarily the ad network's fault; rather, it's about adopting and mastering innovative new strategies to capture and monetize reader attention effectively in an ever-evolving digital ecosystem. This guide provides one such powerful strategy designed for today's web.
The imperative new strategy for enhanced blog monetization involves deploying dynamic floating ads. These highly visible ad units are designed to consistently capture visitors' attention, thereby significantly increasing crucial ad impressions and driving a higher volume of ad clicks. This innovative approach positions floating ads as an excellent solution for genuinely boosting ad revenue, a feat that traditional static display ads, often ignored by seasoned visitors, simply cannot achieve on their own.
For blogs with a substantial base of returning visitors or high user engagement, a common challenge emerges: "ad blindness." Over time, frequent readers tend to overlook and rarely click on fixed banner advertisements. This phenomenon directly translates to a quantifiable daily ad revenue loss for publishers. By integrating persistent floating ads, you can actively combat this issue, helping online publishers to effectively boost their CPM (Cost Per Mille) and critically improve their CTR (Click-Through-Rate). This strategic implementation results in generating substantially more income from virtually any ad network, optimizing your overall blog advertising strategy.
Furthermore, floating ads prove to be exceptionally effective for websites or blogs that, despite high traffic, may lack ample or optimal empty space for monetization within the main content flow. Frequently, the left and right margins of a blog design remain as untapped, vacant areas. These traditionally "idle spaces" represent prime opportunities that can be effortlessly utilized and transformed into active income generators with a smart floating ad placement system. This intelligent use of previously underutilized screen real estate directly leads to a greater number of clicks on AdSense ads or other third-party advertisements, maximizing your site's monetization potential without compromising content readability.
The biggest advantage of this method is that it doesn't occupy valuable space within your blog content, sidebar, or footer. Moreover, floating AdSense ads are a smart technique to potentially double your ad revenue. A special widget has been designed for floating AdSense and other third-party ads on the left or right side of any Blogger blog.
In this tutorial, I'll show you how to use a fantastic widget to display Floating "160px X 600Px" AdSense ads on either the right or left side of your blog.
This widget isn't just for AdSense ads; you can use it to float any display ad banner. Many bloggers monetize with affiliate ads, and this widget can be an ideal option for them to display these as floating banners.
What is a Floating Ad?
Floating ads are rich media web advertisements that appear over the content of a webpage. They "float" or "fly" over the page. Typically, floating ads appear on the left, right, or even in the middle position of the webpage and fade away after 5 to 30 seconds. Alternatively, visitors can close them by clicking a close button.
Common types include full-screen, vertical, and small rectangular floating ad banners. Some floating ads lack a close button, forcing visitors to interact with them to proceed. Classier versions come in various shapes and sizes, often featuring sound, animation, and interactive elements.
Floating ads utilize various technologies, such as:
- Flash animation
- Dynamic HTML (DHTML)
Depending on the web browser, the majority of floating ads can display in different ways.
Benefits of Using Floating Ads
Many publishers prefer floating ads to capture visitor attention and increase click-through rates, willingly running them on their websites.
It's challenging to generate significant revenue solely from viewable ad impressions. The more clicks you get, the more revenue you can generate from your ad network.
The benefits of Floating ads include:
- Ensuring maximum viewer attention.
- Animated floating ads with sound feeling like TV commercials, prompting visitors to watch them.
- Visitors cannot ignore full-screen floating ads.
- Being more influential than non-floating display ads.
- Consistently achieving a high click-through rate.
- Increasing ad impressions, with many publishers generating $1 to $8 per 1,000 impressions.
- Ultimately generating higher ad revenue.
According to HowStuffWorks:
Is it Allowable to Display Floating Ads in AdSense?
A common question is: “Can I use AdSense ads in a float div on my blog?”
The simple answer is 'No'. AdSense does not allow their ads to appear in a “floating” or “sticky” position. Google AdSense prioritizes user experience, restricting floating ad implementations to ensure a secure and positive interaction.
However, AdSense does have a Page-level ad feature that pops up only on the mobile web, but it might not generate the estimated ad revenue you desire.
Should I Place Floating AdSense Ads on My Website?
While AdSense guidelines generally discourage floating ads, you can use them safely if you integrate them naturally. Google AdSense has several ad placement guidelines, such as:
- You cannot try to grab unnatural attention to your AdSense ads.
- You are not allowed to place ads under a misleading header.
- You cannot cover content using ads.
And so on.
So, if your floating ads don't cover content and don't unnaturally grab visitor attention, you can place a floating ad banner. I developed this floating ad banner to place two vertical ads on the left and right sides of any website. This approach aims to maximize ad revenue without forcing user attention, allowing publishers to utilize underused spaces for ad display.
This widget allows you to float any ad banner from any ad network. So, if you're not using Google AdSense, this floating ads widget can still be highly useful for maximizing your ad revenue.
How to Add Floating AdSense Ads to the Left or Right Side On Blogger?
This is an excellent technique to float your display ads on the left or right side of your Blogger BlogSpot.
All ad networks have unique terms and conditions for using their display ad banners, and all publishers must follow these instructions. Before proceeding, carefully read your current ad network’s Terms of Service. If you intend to use affiliate ads, read the Terms of Use of the respective affiliate network. Many allow floating ads, while some do not.
I've split this tutorial into two parts. First, you'll get the AdSense ad script from your AdSense account, and then we'll show you the floating ad script to integrate the AdSense code.
How to Get the AdSense Code?
You can use any ad script, but for demonstration purposes, I'm showing the tutorial with Google AdSense. To get the responsive AdSense ad code, follow these steps:
- Log in to your AdSense account.
- Click
Ads
to expand the vertical menu and clickAd units
. - Click
+ New ad unit
. - Select Text & display ads.
- Now give the name of your Text & display ads and select the Responsive ad unit.
- Finally, click the Save and get code button to retrieve the AdSense ad code.
- Simply copy the ad code into a notepad and click the Close button to close the ad code window.
You have successfully generated a responsive AdSense ad code, and later on, we will use it in your floating ad widget to display floating ads in your blog. Your generated ad code will look like the below:
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- Text & display ads -->
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-8888888888888888"
data-ad-slot="3333333333"
data-ad-format="auto"
data-full-width-responsive="true"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
Now we will advance to the second part of the tutorial.
Features of This Floating Ad Widget
- Fully responsive: Works beautifully on all screen sizes; hides or adapts on mobile.
- Easy to customize: Place your own ad code in a single spot.
- Dismissible: Users can close the ad, and it won’t reappear until the next session.
- SVG close icon: Modern, crisp, and accessible.
- Accessibility: Keyboard navigation, ARIA roles, and labels.
How to Integrate AdSense Ads with Floating Ad Widget?
This is the main part of the tutorial. Here we will show you the total integration process of your generated AdSense code with the Floating ad widget. Please follow the below steps:
Option 1: Placing in the <head>

You will see the floating ads like the featured image on the both left and right side of your blogger theme.
Code Explanation (of this Floating Ad widget)
Here's an explanation of a common code structure you might use, such as for a floating ad, which combines HTML, CSS, and JavaScript.
HTML:
- Two
.floating-ad
containers: one for the left, one for the right. - Each has a header with a "Sponsored" label and a close button using an inline SVG "X" icon.
- Each ad body contains a placeholder image—replace this with your ad code.
CSS:
.floating-ad
is fixed to the left or right, with a modern card look.- Responsive breakpoints ensure the ads adapt or hide on smaller screens.
- The close button and SVG are styled for clarity and accessibility.
JavaScript:
- Adds click and keyboard support to close each ad.
- Uses
sessionStorage
so the ad stays hidden if closed, until the browser/tab is closed. - No external dependencies—works everywhere.
Customize the Ad Code:
- Find the
<!-- PLACE YOUR LEFT AD CODE BELOW -->
and<!-- PLACE YOUR RIGHT AD CODE BELOW -->
comments. - Replace the
<img ...>
with your own ad script (e.g., AdSense, affiliate banners, etc.).
For Other Platforms (WordPress, Static Sites, etc.):
- HTML: Place the HTML code in your template or page where you want the ads.
- CSS: Add the CSS to your site’s main stylesheet or within a
<style>
tag in the<head>
. - JavaScript: Add the JavaScript before the closing
</body>
tag or in your site’s JS bundle.
Customization Tips:
- Show only one ad: Remove the HTML/CSS/JS for the side you don’t want.
- Change ad size: Adjust the
width
in the CSS and the ad image/script. - Change label: Edit the
<span class="floating-ad-label">Sponsored</span>
text. - SVG color: Change
stroke="#fff"
in the SVG to match your theme. - Ad code: Insert your ad provider’s code (e.g., Google AdSense, BuySellAds) in place of the
<img>
tag.
FAQ:
- Q: Is this widget mobile-friendly?
- A: Yes, it adapts or hides on small screens to avoid interfering with mobile UX.
- Q: Can I use this on any blog or website?
- A: Yes, as long as you can add custom HTML, CSS, and JavaScript.
- Q: Is the copyright visible to users?
- A: No, it’s only in the code comments for protection and attribution.
Visual Reference:
- Left Ad: Floats left, with close button and your ad.
- Right Ad: Floats right, with close button and your ad.
You now have a modern, responsive, and copyright-protected floating ad widget for both sides of your blog!
Wrapping It Up: Elevate Your Ad Strategy
In conclusion, incorporating floating ad widgets into your blog or website can be a transformative step towards significantly boosting your online revenue. Unlike static banners that often blend into the background, floating ads offer unparalleled control over placement, allowing your advertisements to 'float' dynamically across the screen, always remaining within the user's line of sight.
This increased visibility translates directly into higher ad impressions and, crucially, improved click-through rates. While the potential for substantial earnings is clear, it's vital to implement floating ads responsibly. Our primary recommendation is to position these dynamic ads on the left and right margins of your webpage. This strategic placement ensures maximum ad exposure without obstructing your valuable content, thereby maintaining a positive user experience, which Google AdSense, and indeed all ad networks, highly prioritize.
Consider the vast amount of often-overlooked 'white space' on most websites, typically ranging from 1100px to 1200px in width. These idle areas are prime real estate waiting to be monetized. By deploying this innovative floating ad widget, you effectively transform these previously unproductive zones into active income streams. The inherent motion and persistent presence of floating ads naturally draw the eye, making your advertisements more engaging and compelling than traditional placements.
The beauty of this solution lies in its ability to dramatically increase your ad revenue by capturing sustained visitor attention, leading to more clicks and, consequently, a healthier bottom line. It's a smart, non-intrusive way to maximize the monetization potential of your digital presence. So, if you're ready to move beyond conventional ad placements and truly supercharge your blog's earning potential, integrating these floating ad widgets is your next strategic move. Don't let valuable screen real estate go to waste – make every pixel count towards a more profitable blogging journey!

Domain is just a name which you can buy within $7 to $10. and
Hosting is a place where your blog will retain. For example..BloggerSpice.com is a domain name. And I am using Google Blogger as my hosting. Everything of my web data pictures has stored on Google Hosting site.

Another issue is Facebook this is a great problem for every blog. Because when you try to share something then posts image thumbnail will display different image or unrelated image, For this reason you can use auto sharing technique through third party plugins. Please follow the below tutorial---
http://www.bloggerspice.com/2013/04/auto-publish-your-blog-posts-to-5.html
But before that you can try Opera Browser..it work best. I have tried to share though Opera it is able to display relevant image on Facebook while I share.
Tell me how to insert this code in the bottom of the page... i mean i want to float 768x90 ad in the bottom of my page.down side.

I have added a credit URL with this widget but it doesn't redirect your Blog to my Blog. rather it will open the widget page at the background. however you can remove this http://www.bloggerspice.com/2013/05/how-to-float-adsense-and-other-third-party-ads-on-left-or-right-side-of-the-blogger-template.html URL to stop redirecting.

Thanks for sharing this informative post.
Currently Google AdSense, Media.net and some other ad agency providing responsive ads. So if you get approval from Google AdSense then you can use Responsive ad unit on your Blog. :wr
Yes this widget violate the terms and services of AdSense. but you can use this for other advertising platform. IF you want to use this widget for AdSense then you should use it for your own risk. However I have seen many website using this widget for 1 year but Google still didn't penalize.
:t
:re
Google AdSense doesn't allow any modification and tweak on their ad banner. So if you want to use this widget then you have to use this by your own risk.
But any other ad platform you can easily use this widget. Thank you.

Thanks for your lovely feedback :up
Please, can you help me with related post code that displays on desktop view?. The one l added displayed only on mobile view. Visit my blog @ www.judybestview.blogspot.com.please help!thanks
Thanks a lot.
This is a vertical style AdSense space that shows outside of the box to utilize the extra space from your blogger theme.
In mobile device there is no space on right or left side of the blogger site. So it becomes hidden there. This is good for your site. and your visitors won't feel annoying.
However to show ads in the middle of the blog post in all device you can follow below tutorial-
