Managing display ad campaigns across platforms like Sizmek and Campaign Manager 360 (CM360) inevitably leads to one persistent technical challenge: how to set up tag workflows that keep clickTag behavior perfectly consistent across every banner size. Conflicting scripts, scaling issues, and the risk of tracking discrepancies can result in lost engagement data and wasted time troubleshooting. Our experience at SizeIM shows this problem multiplies as campaigns demand more creative versions and stricter compliance requirements from ad networks.
Today, we’ll walk through the technical and practical steps to generate a reliable, scalable Sizmek/CM360 tag workflow—guaranteeing that clickTag functionality is identical no matter if your banner is a 300×250, 728×90, or 970×250. As the industry moves toward greater automation in ad production, it’s essential to know how top agencies leverage tools like SizeIM to standardize and simplify this process from start to finish.
What Are Sizmek and CM360 Tags? The Core Definition
Sizmek (now integrated within Google Marketing Platform and CM360) and Google Campaign Manager 360 both rely on ad tags—snippets of JavaScript or iFrame code containing macros to track impressions, clicks, and conversions. The clickTag is a key parameter instructing the ad where to redirect the user upon click, while also ensuring the correct click tracking is fired for attribution and reporting.
- CM360 Tags: Use macros such as
${CLICK_URL}ordata-dcm-click-trackerto ensure clicks are tracked consistently. - Sizmek Tags: Embed custom click trackers and macros that require careful placement and compatibility checks across banner sizes.
Getting this right means you avoid issues with network approval, missing click data, or misattributed conversions. For agencies working in volume, a standardized and automated approach is not just a convenience—it’s a competitive necessity.
Why ClickTag Consistency Is Challenging in Multi-Size Banner Production
Traditionally, designers build dozens of banner sizes manually. This leads to three core challenges:
- Manual Editing: Each file often needs unique adjustments to clickTag scripts, increasing risk of inconsistent tracking.
- Element Scaling: Incorrect placement or scaling of interactive areas, breaking click-through behavior.
- Workflow Bottlenecks: Time spent verifying and correcting exported files cuts efficiency and introduces potential for error.
This is why agencies, designers, and marketing teams increasingly turn to automated solutions that enforce uniformity programmatically—saving time and preventing costly campaign delays.
A Step-by-Step Sizmek/CM360 Tag Workflow Using SizeIM
At SizeIM, we developed a systematic approach that transforms the typical manual workflow into a seamless, reliable tag setup. Here’s our process, which any agency or designer can adapt for maximum reliability:
- Template Selection: Start with one of SizeIM’s 200+ display ad templates, all optimized for network compliance including Sizmek and CM360 standards.
- Centralize Brand & Tag Data: Upload logos, fonts, and color palettes using the Brand Kit. Input your tag macros (such as clickTag or
${CLICK_URL}) directly within the editor—these values will remain consistent as the ad is duplicated and resized. - Choose Required Banner Sizes: Instantly select all necessary formats—from rectangles to billboards, including 300×250, 728×90, 160×600, 970×250, and more. No additional manual script or tag edits required for each size.
- Embed Tags Once: Implement the clickTag and relevant macros at the template level. For example, add a CM360 JavaScript structure with
data-dcm-click-tracker="${CLICK_URL}". In Sizmek, place the macro in the required field during setup. - Responsive Resizing and Validation: Our responsive framework ensures the clickTag remains full-canvas and identical in every exported banner. No matter the output size, the click area is accurately mapped and the script integrity is preserved.
- Bulk Export and Testing: Download the complete ad set as a ZIP archive. Each file is ready for upload, with all tags verified during rendering. Test within CM360 or Sizmek’s native preview to confirm identical click-through behavior and macro firing.
This process is designed for efficiency. By setting up macros and clickTag values once at the template level, you avoid repetitive editing and minimize risk—making it ideal for campaigns with wide creative scope and tight turnaround times.
Example: CM360 ClickTag Script in Action
After embedding your CM360 macro in SizeIM’s editor, the following tag structure will adjust automatically per ad size:
<SCRIPT language='JavaScript1.1' SRC="https://ad.doubleclick.net/ddm/adj/NXXXX.site-keyname/BYYYYYYY;sz=300x250;ord=[timestamp];click=?"></SCRIPT>
When you export a 728×90 leaderboard version, SizeIM replicates the tag with updated size parameters—while maintaining the click behavior and network compliance requirements without manual intervention or error-prone edits.

Best Practices for Sizmek/CM360 Tag Deployment with SizeIM
- Centralize Your Click Settings: Always input the clickTag or click macro at the template level, not within individual size versions.
- Use Consistent Layering: Make your clickable area a top-level canvas shape or button set to 100% of the banner’s dimensions. This avoids broken or misaligned click areas on unusual sizes.
- Validate During Export: Use SizeIM’s preview and download all formats in one ZIP file. Upload to CM360 or Sizmek’s previewer to confirm that click behavior and impression tracking fire as expected in every format.
- Leverage Brand Kit Management: By holding logos, color codes, fonts, and tag macros in one place, you keep your team and creative output fully aligned—even when scaling to dozens of banner variants.
- Stay Current on Ad Specs: Both Sizmek and CM360 periodically update their compliance documentation. Regularly review these to ensure your templates reflect new tagging requirements.
