Setting up retargeting pixels on 1smart.link

This guide walks you through saving retargeting pixels in the 1smart.link Pixel Manager and assigning them to your links, bio page widgets, and bio pages. Once a pixel is saved, you can reuse it across your entire account with a single checkbox — no need to paste tracking IDs repeatedly.

Note: You need an active 1smart.link account to follow this guide. The Pixel Manager is available at Dashboard → Pixels.

How the Pixel Manager works

The Pixel Manager is a centralised pixel library. You save each pixel once — with its platform, tracking ID, and a friendly name — and it appears as a checkbox option whenever you edit a link, widget, or bio page. This save-once-use-everywhere approach means you configure your tracking IDs in one place and assign them wherever you need them.

1smart.link supports ten platforms out of the box:

Platform	What you need to provide
Meta (Facebook / Instagram)	Meta Pixel ID
GA4 (Google Analytics 4)	Measurement ID
Google Ads	Conversion ID + Conversion Label
GTM (Google Tag Manager)	Container ID
TikTok	Pixel ID
LinkedIn	Partner ID
Twitter/X	Pixel ID
Snapchat	Pixel ID
Pinterest	Tag ID
Custom Code	Full script or noscript snippet

If your tracking platform is not in the list — for example, Mixpanel, Segment, or Amplitude — use the Custom Code option and paste the full HTML snippet exactly as your platform provides it.

Save a new pixel

Follow these steps to add a pixel to your library.

1. Log in to your dashboard at www.1smart.link.
2. Click Pixels in the left sidebar, or navigate directly to /dashboard/pixels.
3. Click Add Pixel.
4. Choose the platform from the list (Meta, GA4, Google Ads, GTM, TikTok, LinkedIn, Twitter/X, Snapchat, Pinterest, or Custom Code).
5. Paste the required tracking ID into the field provided. For Google Ads, you will see two fields — one for the Conversion ID and one for the Conversion Label. For Custom Code, paste the entire script snippet.
6. Give the pixel a name. This is an internal label only — your visitors will never see it. Use something descriptive like "Main Meta Pixel", "Shop Account GA4", or "TikTok — Summer Campaign".
7. Click Save.

Your pixel now appears in the Pixel Manager library and is ready to be assigned.

Tip: Create clear, descriptive names if you manage multiple pixels for the same platform. For example, "Meta — UK Store" and "Meta — US Store" are easier to tell apart than "Meta 1" and "Meta 2".

Assign a pixel to a short link

When you assign a pixel to a short link, the pixel fires whenever someone clicks that link.

1. Go to Dashboard → Links or navigate to /dashboard/links.
2. Find the link you want to track and click Edit.
3. Scroll down to the Pixels section and expand it.
4. Tick the checkbox next to each pixel you want to fire on this link's click. You can select multiple pixels — for example, both your Meta Pixel and your GA4 Measurement ID.
5. Click Save.

From this point forward, every click on that short link will fire the selected pixels. You can return to the link's settings at any time to add or remove pixels.

Assign a pixel to a bio page widget

Widget-level pixels fire when a visitor interacts with a specific widget on your bio page. This is useful when you want granular tracking — for instance, tracking clicks on your "Shop Now" button separately from your "Watch Video" button.

1. Open the BioLink Builder for the bio page you want to edit.
2. Click on the widget you want to track. Its settings panel will expand.
3. Find the Pixels section within the widget settings.
4. Tick the checkboxes for every pixel that should fire when someone interacts with this widget.
5. Click Save on the widget.

Repeat for each widget you want to track individually.

Assign a pixel at bio page level

Page-level pixels fire on every page view — as soon as someone lands on your bio page, regardless of which widget they interact with. This is ideal for broad retargeting audiences and general analytics.

1. Open the bio page you want to edit.
2. Go to the bio page's Settings → Tracking.
3. Tick the checkboxes next to the pixels that should fire on every page view.
4. Click Save.

Tip: You can combine page-level and widget-level pixels on the same bio page. Use a page-level pixel for general audience building (e.g., Meta retargeting) and widget-level pixels for conversion tracking on specific buttons (e.g., Google Ads conversion on your purchase link).

Platform-specific notes

Meta (Facebook / Instagram)

You will find your Meta Pixel ID in the Events Manager section of your Meta Business Suite. The ID is a string of numbers, typically 15–16 digits long. Paste only the numeric ID — do not paste the full script tag.

GA4 (Google Analytics 4)

Your GA4 Measurement ID starts with G- followed by a string of characters (e.g., G-XXXXXXXXXX). You can find it in your GA4 property under Data Streams.

Google Ads

Google Ads requires two values: the Conversion ID and the Conversion Label. Both are available in your Google Ads account under Tools → Conversions. The Conversion ID typically starts with AW-.

GTM (Google Tag Manager)

Your GTM Container ID starts with GTM- followed by a string of characters. You will find it at the top of your GTM workspace.

TikTok

Your TikTok Pixel ID is available in the TikTok Ads Manager under Assets → Events. It is a numeric string.

LinkedIn

LinkedIn uses a Partner ID rather than a pixel ID. You will find it in LinkedIn Campaign Manager under Analyse → Insight Tag.

Twitter/X

Your Twitter/X Pixel ID is available in the Events Manager section of your X Ads account.

Snapchat

Your Snapchat Pixel ID is available in your Snap Ads Manager under Events Manager.

Pinterest

Pinterest uses a Tag ID. Find it in Pinterest Ads Manager under Conversions → Pinterest Tag.

Custom Code

Use this option for any tracking platform not listed above. Paste the full script or noscript snippet exactly as the platform provides it. Do not modify the code unless the platform's own documentation instructs you to.

Warning: Incorrectly formatted custom code can prevent your bio page or link from loading properly. Always test after saving by opening the link or bio page in a private browser window and confirming the page behaves as expected.

What happens next

Once you have saved and assigned your pixels, they begin firing automatically based on the assignment level:

• Link-level pixels fire on every click of that short link.
• Widget-level pixels fire when a visitor interacts with that specific widget.
• Page-level pixels fire on every bio page view.

You can verify that pixels are firing correctly by using your ad platform's built-in diagnostics tool — for example, the Meta Pixel Helper browser extension or the Google Tag Assistant.

To update or remove a pixel later, return to Dashboard → Pixels, edit or delete the pixel from your library, and the change will apply everywhere that pixel was assigned.

Troubleshooting

Pixel does not appear in the assignment list

Make sure you saved the pixel in the Pixel Manager first. Navigate to /dashboard/pixels and confirm it appears in your library. If it is missing, add it again following the steps above.

Pixel fires but no data appears in your ad platform

Double-check that you pasted the correct ID. A single missing or extra character will cause the pixel to fire silently without registering in your platform. Compare the ID in your Pixel Manager with the one shown in your ad platform's settings.

Bio page loads slowly after adding Custom Code

Review the custom code snippet you pasted. Some platforms provide synchronous scripts that can delay page rendering. Check whether your platform offers an asynchronous version of the snippet and use that instead.
