Trimrly Help Center

Pinterest sits in an interesting position in the digital advertising landscape. Users come to the platform specifically looking for ideas, products, and inspiration, which makes the purchase intent behind a lot of Pinterest browsing genuinely high. But unlike search ads where intent is spelled out in a keyword, Pinterest intent is expressed through saves, clicks, and engagement patterns that the platform's algorithm picks up over time. That's what makes the Pinterest Tag so important. Without it, your ad account can't connect those signals to real outcomes on your side.

Adding your Pinterest Tag to Trimrly means every visit to a short link redirect page, bio page, or QR code landing page gets reported back to your Pinterest Ads Manager. The tag fires the base pagevisit event automatically on each visit, starts building your retargeting audiences in the background, and feeds Pinterest's algorithm the conversion data it needs to optimize delivery toward users most likely to take action.

Your Pinterest Tag ID is a numeric string that identifies your Pinterest Ads account. It looks like this: 
1234567890123

What Is the Pinterest Tag?

The Pinterest Tag is a piece of JavaScript that loads on your pages and tracks visitor behavior tied to your Pinterest Ads campaigns. It works in two layers that need to be understood separately, because they serve different purposes and require different setup steps.

The Base Code

This is the foundational script that should run on every page where you want Pinterest to track activity. It loads the Pinterest tracking library, initializes your Tag ID, and fires a pagevisit event automatically on every page load. The base code is generated once per account and contains your unique Tag ID embedded inside it. When you connect Pinterest to Trimrly, Trimrly handles loading this base code on your short link redirect pages, bio pages, and QR code landing pages automatically.

Event Codes

On top of the base code, you can add event-specific snippets to track particular conversion actions. These go on specific pages rather than every page, and they tell Pinterest what kind of action occurred. Pinterest uses a fixed set of standard event types, and using the correct names matters since the algorithm depends on recognizing them. Events are case-sensitive in Pinterest's system, so pagevisit and PageVisit are treated identically, but a misspelled event name won't be recognized.

Pinterest Tag Standard Events Explained

Pinterest supports nine standard event types that cover the most common conversion actions. Here's what each one tracks and when you'd use it:

• pagevisit - Fires when a user views a specific page. This is the default event the base code fires on every page load. Use a targeted pagevisit event on high-value pages like product pages or pricing pages to track visits to those specific URLs as conversion-level actions.
• signup - Fires when a user registers, creates an account, or subscribes. Useful when Trimrly links drive traffic to registration pages and you want to count only completed signups rather than page loads.
• lead - Fires when a user submits a contact form, requests a quote, or shows intent-level interest in your product. Good for service businesses where the goal is generating enquiries rather than direct purchases.
• checkout - Fires when a user completes a purchase transaction. Can be passed with value, currency, order quantity, and line item data to enable ROAS measurement in your Pinterest Ads reporting.
• addtocart - Fires when a user adds a product to their cart. Combined with a checkout event, this lets you measure drop-off between cart and purchase and build abandoned cart retargeting audiences.
• viewcategory - Fires on category or collection pages. Useful for building audiences of people who browsed a specific product type without viewing individual products yet.
• search - Fires when a user performs a site search. Captures high-intent visitors who are actively looking for something specific on your site.
• watchvideo - Fires when a user watches a video on your page. Can be passed with a video title parameter to distinguish between different video assets in your reporting.
• custom - A catch-all type for any action that doesn't fit the standard events. Custom events show up in conversion reporting but Pinterest treats them as a single "Custom" category, so you can't distinguish between different custom event types in your reports. Use standard events whenever possible.

How Pinterest Attributes Conversions

One thing worth understanding before you set up Pinterest conversion tracking is how the platform attributes those conversions. Unlike platforms that only count click-based attribution, Pinterest uses a three-window model that gives you a more complete picture of how your ads contribute to results.

The default windows are: a 30-day click-through window (conversions from users who clicked your ad within the last 30 days), a 1-day view-through window (conversions from users who saw your ad but didn't click, within the last 24 hours), and an engagement window (conversions from users who saved or engaged with your Pin before converting). You can adjust these windows inside your Pinterest Ads settings based on your typical purchase or consideration cycle.

For products with longer consideration periods, like home goods or higher-ticket items that Pinterest users often save and return to later, a broader attribution window tends to give Pinterest more credit than pure click-through tracking. For impulse-type purchases, the default settings usually work well.

How to Find Your Pinterest Tag ID

Your Tag ID is the numeric identifier for your Pinterest Tag. Here's exactly where to locate it:

1. Sign in to Pinterest Ads Manager at ads.pinterest.com.
2. Click Ads in the top navigation, then select Conversions from the dropdown menu.
3. If you don't have a tag yet, click Create Pinterest Tag and follow the prompts. Pinterest generates one tag per account.
4. Once a tag exists, your Tag ID is displayed on the Conversions page, a numeric string similar to 1234567890123.
5. Copy the full numeric string. That's what you'll paste into Trimrly.

You can also find the Tag ID embedded in the base code snippet if you choose to view the raw code. It appears in the pintrk('load', 'YOUR_TAG_ID') line near the top of the script.

How to Add Pinterest Tag to Trimrly

Once you have your Tag ID, adding it to Trimrly takes about two minutes through the Tracking Pixels section:

1. Log in to your Trimrly account. No account yet? Register for free here.
2. In the left sidebar, click Tracking Pixels under the Channels section.
3. On the Add Pixel page, open the Pixel Provider dropdown and select Pinterest.
4. In the Pixel Name field, enter a label you'll recognize, such as "Pinterest Tag" or the name of your current campaign.
5. Paste your numeric Tag ID (for example 1234567890123) into the Pixel Tag field. Paste the number only, not the full JavaScript code snippet.
6. Click Add Pixel to save.

From this point on, Trimrly loads the Pinterest Tag base code on all short link redirect pages, bio pages, and QR code landing pages. Every visit fires a pagevisit event back to your Pinterest Ads Manager account automatically.

Setting Up Conversion Events in Pinterest Ads Manager

The base tag connection handles page view tracking on all Trimrly pages. To count specific actions like signups, leads, or purchases as conversions, you need to set those up as conversion events inside Pinterest Ads Manager as well.

In Ads Manager, go to Ads then Conversions, and click into your tag. From there you can create conversion events by defining which event type should fire on which URL condition. For most Trimrly setups, URL-based conversion rules work well. For example, defining a signup event to fire when a user reaches a URL containing "/thank-you" counts completed registrations without requiring any additional code on your destination pages.

If you need more granular event tracking, such as capturing the purchase value passed with a checkout event or product IDs passed with an addtocart event, those require event code snippets placed directly on the destination pages or set up through Google Tag Manager. If you've already connected GTM to Trimrly, you can build those event triggers inside your GTM container and they'll fire through the same Trimrly connection without needing a second pixel entry.

How to Verify Your Pinterest Tag Is Working

Confirm the tag is firing before you launch live campaigns that depend on conversion data. A few minutes spent verifying now avoids a lot of wasted spend later.

Install the Pinterest Tag Helper Chrome extension from the Chrome Web Store. Once active, visit one of your Trimrly short link redirect pages or bio pages. The extension shows whether the Pinterest base code loaded, which Tag ID it detected, and whether any events fired. A green checkmark next to your Tag ID means the connection is working correctly. Any warnings or errors indicate something to fix before going live.

For a secondary check, go back to Ads then Conversions in Pinterest Ads Manager and look at the tag status. If the tag is receiving signal, the status will show as Active rather than Unverified. Pinterest typically processes initial tag data within a few hours, so if you just connected the tag, give it some time before checking. A reporting delay of 24 to 48 hours is normal for conversion data to appear fully in your campaign reports.

Important Notes Before You Start

• Paste the Tag ID only, not the full script. Trimrly wraps the base code for you. The Pixel Tag field only needs the numeric Tag ID itself, like 1234567890123. Pasting the full JavaScript snippet will break the integration.
• Copy the Tag ID exactly as shown. The ID is a numeric string and must be complete. Missing even one digit prevents Pinterest from matching the tag to your account. Copy it directly from Ads Manager rather than typing it manually.
• Allow up to 48 hours for conversion data. The Trimrly connection and tag firing happen in real time, but Pinterest's Ads Manager reporting can take 24 to 48 hours to display conversion data fully. Don't assume something is broken if the numbers look low on the first day.
• Configure your event types in Ads Manager. The base code fires a pagevisit event on every Trimrly page automatically. For more specific conversions like signups, leads, or purchases, you still need to configure those event definitions inside Pinterest Ads Manager so the platform knows what to count as a conversion for your campaigns.
• Avoid duplicate tag installs on the same pages. If you're managing the Pinterest Tag through Google Tag Manager already connected to Trimrly, don't add a second instance through the standalone Pinterest slot on those same pages. Two base codes firing from the same Tag ID inflates your audience size counts and distorts attribution data.
• Privacy compliance applies to Pinterest too. For visitors in GDPR-covered regions or other markets with consent requirements, the Pinterest Tag should be gated behind your cookie consent banner. Pinterest provides guidance on consent-based tag implementation, and running the tag on unconsented visitors carries legal risk regardless of where the tag code is hosted.

Why Connect Pinterest Tag with Trimrly?

Pinterest users frequently come to the platform with purchase intent already formed. They're building boards, saving products, and comparing options before deciding. Ads that reach these users at that moment can be highly effective, but only if you can tell the algorithm which outcomes you actually care about. The Pinterest Tag is how you communicate that.

Connecting the tag to Trimrly means that intent-rich audience isn't lost the moment someone clicks through to your content. Whether they land on a Trimrly short link redirect, visit your bio page, or scan a QR code from a printed campaign, that visit fires back to Pinterest and starts contributing to your audience and conversion data.

Here's what that looks like in practice:

• Conversion measurement for Pinterest campaigns. You'll know exactly how many visitors from Pinterest ads completed the actions that matter to your business, not just how many clicked. That shifts your optimization from cost-per-click to cost-per-result, which is a fundamentally more useful metric for evaluating whether Pinterest is worth spending on for your product category.
• Retargeting audiences built from real traffic. Everyone who visits a Trimrly page where the Pinterest Tag fires gets added to your website visitor audience in Ads Manager. You can retarget these users with follow-up Pins, exclude already-converted visitors from acquisition campaigns, or use the audience as a seed for lookalike targeting to find new users with similar profiles.
• Algorithm optimization over time. Pinterest's delivery system uses conversion events to learn which users in your target audience are most likely to take action. The more checkout, signup, and lead events it sees from your Trimrly traffic, the better it gets at finding similar users and concentrating your budget there.
• ROAS visibility for e-commerce campaigns. If you pass purchase value with your checkout events, Pinterest Ads Manager displays your return on ad spend directly in campaign reporting. That makes it straightforward to compare Pinterest against other channels and make budget allocation decisions based on actual revenue contribution rather than proxy metrics.
• Offline-to-online attribution via QR codes. Trimrly QR codes placed in physical spaces, packaging, or print materials fire the Pinterest Tag the moment someone scans and lands on the redirect page. This connects offline touchpoints to your Pinterest ad attribution and gives you a real picture of how print and in-person campaigns contribute to your digital marketing goals.
