Adsterra Smartlink: How It Works and How to Set It Up
What an Adsterra Smartlink is, how to create one in a few steps and where to place it safely, based…

The Adsterra Social Bar is an ad format that shows small notification-style ads on your site from a single line of code. You paste the script before the closing body tag, and ads start rolling. In this guide I explain how it works, how to set it up step by step, and the mistakes I would avoid.
I run Adsterra on my own sites, so I will keep this practical. I only use facts from Adsterra’s own publisher guides, and I will tell you where the real limits are.
According to Adsterra, the Social Bar is a display ad unit that looks like friendly notifications, icons, overlays or widgets. Ads can look like push notifications, chat bubbles or small widgets that appear on top of your page.
It is built from several ad types that show in turns: In-Page Push, Interstitial, Icon Notifications, Custom Banner and Widget. Each visitor can see different offers, and you only add one script.
If you are still comparing formats, read my overview of Adsterra ad formats first. The Adsterra Social Bar is only one of several units you can choose from.
Unlike web push ads, Social Bar does not need the visitor to subscribe to anything. Adsterra says it does not depend on browser subscriptions, so all your visitors can see it.
It also does not need a fixed spot like a banner. It appears as a notification-style element and, per Adsterra, it does not block your content because of its dynamic iFrame technology.
Adsterra’s Help Center lists it as a good fit for websites with well-built user experience, for iOS users and for getting around ad blockers. Its pricing models are listed as 75% CPA, 20% CPM and 5% CPC.
| Point | Social Bar | Web push | Banner |
|---|---|---|---|
| Needs visitor opt-in | No | Yes | No |
| Needs a fixed spot | No | No | Yes |
| Code needed | One script | Subscription setup | One script per size |
This table is based on how Adsterra describes each format in its publisher guide.
Here is the flow from Adsterra’s guide. If you do not have an account yet, follow my steps for creating an Adsterra publisher account first.
If the website is already added, find it on the Websites tab, click the +Ad Unit icon and pick Social Bar. If you do not see the status change, check your email, because Adsterra also sends the ad codes there.
On WordPress, the simplest way is to add the code to your theme footer, because that is where the closing body tag lives. Go to Appearance, then Theme Editor, and add the script before the body tag.
You can also use a Custom HTML widget under Appearance, then Widgets. If you use Elementor, drag the HTML element onto the page and paste the code in. I always back up the theme before editing it, and a child theme is safer. My full tutorial is here: how to add Adsterra ads to WordPress.
On plain HTML sites, open the page layout, search for the closing body tag and paste the code just above it. Adsterra also has a help article for Blogger sites, linked in its Help Center.
As a publisher you do not set these yourself in the code. Adsterra says that if you need a specific location, you should not move the recommended code position and should contact the managers in live chat instead.
It also advises against adding several Social Bar codes to the same page, because that will not increase how often users see ads. Ask your manager for the frequency you want.
Honestly, nobody can promise a number. Adsterra’s own guide gives case studies with large results, but those depend on traffic size, country and niche. I do not use them as a forecast for your site.
Adsterra does say Social Bar CPMs are driven by click-through rate and the quality of your visitors. You can see your own impressions, clicks, CPM and countries in the statistics dashboard, and that is the only data that matters for your site.
Real traffic is the main thing. Read my guide on how to get traffic for Adsterra with safe, allowed methods only.
It suits sites that already get steady, real visitors, especially from mobile devices. If your site has almost no visitors, ads will not earn much, no matter which format you pick.
Before you add anything, ask yourself three simple questions. Is my content useful? Is my site fast on mobile? Would I be happy to see this ad as a visitor? If the answer to any of these is no, fix that first.
Adsterra also reminds publishers that its content restrictions apply, so check them before adding a website. Sites with adult, illegal or misleading content are not a good idea, and I do not recommend them.
Remember that a new ad unit can take a little time to start showing ads, and the numbers in your first days are small and unstable. Give it at least a couple of weeks of real traffic before you judge it, and keep notes on what you changed and when.
Small, steady improvements work better than big experiments. I change one thing at a time so I can see what really made a difference.
If you are new and want a full guided path, my Adsterra course walks through account setup, ad placement and traffic step by step.
Yes. Adsterra is free for publishers to join, and you earn from the ads shown. There is no fee for adding the script.
No. Adsterra says it does not depend on browser subscriptions, so all visitors can see it.
Paste it right before the closing body tag of your page. On WordPress, that is usually the theme footer.
Adsterra suggests using it as an extra income source alongside other formats. Keep your page clean so it stays easy to use.
Contact Adsterra’s managers in live chat. They handle location and frequency changes for you.
The Adsterra Social Bar is simple to install and easy to add on top of your current setup. Set it up correctly, keep your content useful and track your own statistics. For official details, see Adsterra’s Social Bar guide for publishers and its ad unit selection article.
