How To Add ClickTag In Google Web Designer? | Fast Setup Guide

Guide / By

In Google Web Designer, add a Tap Area, wire an Exit event, and let the ad server feed the clickTag URL—no hard-coded links.

Ads need click tracking that ad servers can read and override. In Google Web Designer (GWD), the clean path is to place a Tap Area over the intended hotspot, attach an Exit action, and publish a tidy bundle. That bundle lets Google Ad Manager or Campaign Manager inject the landing URL through a click tag variable or an exit mapping, while your creative stays editable and trackable. This guide shows the fastest build path, safe defaults, code patterns for edge cases, and a checklist to avoid “Missing click tag” upload errors.

What A Click Tag Does And Why GWD Uses An Exit

A click tag is a variable that an ad server sets to control where a click goes. It avoids hard-coding links inside the creative. With GWD, you typically fire an Exit event instead of writing a global var clickTag yourself. Ad platforms detect that exit and attach the final landing page at trafficking time. This keeps tracking intact and lets traffickers swap URLs without asking for a rebuild.

Quick Build Overview

You’ll create a Tap Area, bind an Exit, name it, and publish a zip. Then you’ll upload that zip to your ad server and set the landing page there. The next sections walk through each step with small code helpers when you need a full-canvas click or multiple destinations.

Methods At A Glance (Choose What Fits)

Method Where To Use Notes
Tap Area + Exit (recommended) Standard single click-through Fast setup, ad server detects the exit and supplies the URL
Full-Canvas Tap Area Banner where any click should leave Stretch Tap Area to stage; still fires one Exit
Multiple Tap Areas Separate hotspots with different links Use different metrics IDs; ad server maps each one
Code Hook (advanced) Interactive ads with programmatic exits Call Exit API from JS; keep one source of truth

Step-By-Step: Standard Single Click-Through

1) Add A Tap Area

Open the Components panel and drag Tap Area onto your ad. Position it over the button or cover the full stage if any click should count. Give it a readable name in the Properties panel.

2) Wire The Exit Action

Open the Events panel and add a new event:

  1. Target: your Tap Area.
  2. Event: Touch/Click.
  3. Action: Google Ad → Exit.
  4. Receiver: gwd-ad.
  5. Configuration: set a Metrics ID (for example, cta); leave the URL field blank unless your ad server requires a placeholder.

This tells the runtime to fire an exit that the ad server will pick up. No hard-coded landing page inside the creative.

3) Publish A Zip Bundle

Click Publish → Zip. Keep the default structure. Avoid minifying the specific exit call: ad servers prefer readable click tags and exits. Everything else can be minified.

4) Traffick The Landing URL

Upload the zip to your ad server and set the final landing page there. That value will flow into the exit or click tag variable and your creative will open it on click.

Adding A Click Tag In GWD — Practical Setup

Many teams say “add a click tag” even when using GWD’s Exit flow. The outcome is the same: the ad server controls the final URL, not your code. With GWD, the safest pattern is a Tap Area that triggers Exit. Ad Manager’s HTML5 guidance also warns against hard-coded links inside the bundle, since those break tracking and make later swaps painful. See the official HTML5 guidelines for Ad Manager for the “no hard-coded URL” rule and click-tag readability tips.

Full-Canvas Click Without Guesswork

If the whole creative should be clickable, size the Tap Area to the stage:

  1. Select the Tap Area.
  2. Set Width and Height to 100%.
  3. Ensure it sits at the top layer above art but below UI you still want interactive.
  4. Keep the same Exit mapping as before.

Use the Layers panel to keep this clear. Name the layer “Tap — full canvas” so teammates spot it during reviews.

Multiple Destinations In One Ad

For two or more hotspots, add separate Tap Areas with distinct Metrics ID values. In trafficking, map each ID to its own landing page. This method keeps reporting clean and avoids code forks. If the platform limits you to one destination, route everything to one exit or conform to that platform’s multi-click rules.

Event Setup For Two Hotspots

  • cta_primary → main product page
  • cta_secondary → category or terms page (as allowed by the campaign)

Keep labels short and human-readable. Traffickers should guess the link from the name.

Code Hooks When You Need Logic

Some builds need a programmatic call—maybe the link changes after a user action. You can still trigger an Exit from code. Here’s a safe pattern inside a script tag in your HTML:

<script>
// Call this when you want to leave the ad.
function triggerExit(label) {
  // label matches your Metrics ID, such as "cta"
  if (window && window.gwd && gwd.actions && gwd.actions.events) {
    // Fires the named exit on the main ad component
    gwd.actions.gwdAd.exit(document.getElementById('gwd-ad'), label);
  }
}
</script>

Bind that function to a click handler on a custom element, then keep the same label you used in the Events panel so reporting stays consistent.

Common Pitfalls And How To Avoid Them

Hard-Coded Links Inside The Creative

Direct links baked into HTML or JS block ad-server tracking and make landing pages hard to swap. Ad Manager flags these during upload. Use an Exit with a clean label and set the destination during trafficking. The official guidance calls for “no hard-coded URLs” and easy-to-read click tags, which aligns with the method above.

Minified Or Obfuscated Exit Names

Minify animation code all you like, but keep exit labels readable. A compact label helps the server detect and map them reliably.

Multiple Exits With Vague Labels

A handful of exits is fine. Confusion comes from labels like exit1, exit2. Prefer cta_primary, shop_now, or learn_more. That speeds up QA and keeps reports tidy.

Platform Notes You Should Know

GWD bundle creatives lean on Exit events rather than a global var clickTag. That’s by design and avoids collisions with ad server macros. If you migrate a legacy non-GWD creative that relies on the IAB click tag variable, keep that pattern in the hand-coded build, but stick to Exit inside GWD projects. The IAB guidance explains how the variable acts as a placeholder that ad servers can fill, which matches the overall goal of keeping links outside the creative logic.

Validation, Testing, And Upload

Local Tests

  • Preview in GWD and confirm the Tap Area highlights on hover.
  • Click the hotspot: the preview will attempt the exit. If the preview lacks a final URL, confirm the event still fires in the console without errors.
  • Resize to common sizes to ensure the Tap Area stays aligned with art.

Zip Hygiene

  • One index.html at the root.
  • No external network calls unless required by specs.
  • Relative paths, no absolute file system paths.
  • Readable exit labels; no hard-coded landing page.

Server-Side Checks

Upload the zip and set the landing page in the platform UI. If the server exposes a “detected exits” panel, you should see your labels. If it lists none, revisit the Events panel in GWD and confirm the Google Ad → Exit mapping is attached to your Tap Area and points to gwd-ad.

Troubleshooting Table (Fast Fixes)

Symptom Likely Cause Fix
“Missing click tag” on upload No Exit event, or link hard-coded Add Tap Area → Exit; remove direct URLs
Clicks do nothing in preview Event bound to wrong target Select the Tap Area as target; test again
Only part of the ad clicks Tap Area too small or mis-layered Resize to 100% and bring to top layer
Wrong destination after launch Exit label mapped to old URL Update landing page in the ad server UI
Extra exits detected Multiple Tap Areas left from drafts Remove or rename, then republish

Edge Cases: Multiple Sizes, Dynamic Feeds, And Safe Code

Responsive Or Polite-Load Sets

If you export several sizes, repeat the same Tap Area + Exit pattern in each. Keep labels consistent. That way one trafficking setup can be cloned across sizes without guesswork.

Dynamic URL From Feed

Some buys pass a link via feed. As long as the ad server maps that field to your exit or click tag, you don’t need to pull the URL inside the creative. Keep your Exit call label stable; the platform handles the swap.

Programmatic Trigger After Animation

If the click should fire only after a sequence finishes, gate the exit with a flag:

<script>
let readyToLeave = false;
function revealCTA() {
  // call this when your animation ends
  readyToLeave = true;
}
document.addEventListener('click', function(e) {
  const el = e.target.closest('.cta');
  if (el && readyToLeave) {
    triggerExit('cta'); // same helper shown earlier
  }
});
</script>

Keep the label the same as your Events panel label to avoid double counting.

Official References Worth Bookmarking

The Tap Area component page shows where to wire the event and what each field does. It pairs well with the Ad Manager HTML5 guidance about click-tag readability and avoiding hard-coded links. Here are the two concise references used throughout this guide:

Quality, Review, And Handoff Tips

Name Things Clearly

Use short labels like cta, shop, or learn. Keep names identical across sizes. That makes trafficking and QA faster.

Keep One Source Of Truth

Do not mix a hard-coded link with an Exit. Use one approach. The Exit handles link control and click tracking through the ad server.

Leave Room For Ad Placements

Keep the opening of your page text-led and avoid heavy hero images above the fold. This helps user experience and prevents layout shifts. Tables in this guide are narrow and fit on mobile; the same approach works well in your ad build, too—compact, readable, predictable.

FAQ-Style Clarifications (No Separate FAQ Block)

Do I Need A Global var clickTag?

Not in a standard GWD bundle. Use a Tap Area with an Exit. Let the ad server map the landing page. Reserve a global variable only for custom, hand-coded builds outside GWD.

Can I Track More Than One Link?

Yes. Add more Tap Areas, give each a different Metrics ID, and the platform will list them separately. Keep the count tidy so reports stay readable.

What If The Platform Requires A Named Variable?

Some non-Google platforms read a specific query parameter. If you must hand-code that, do it in a separate non-GWD build for that buy. For everything inside GWD, stick to Exits to stay compatible with Google’s stack.

Copy-Paste Checklist Before You Publish

  • Tap Area present and sized correctly.
  • Event: Touch/Click → Google Ad → Exit → gwd-ad.
  • Readable Metrics ID (no random strings).
  • No hard-coded landing page inside HTML or JS.
  • Zip has one index.html at root with relative asset paths.
  • Upload zip, set landing page in the ad server UI, verify detected exits.

Wrap-Up: The Reliable Pattern That Scales

The fastest, ad-safe method inside GWD is Tap Area → Exit → ad-server landing page. It meets tracking needs, keeps trafficking flexible, and avoids upload errors. Use full-canvas coverage when every click should leave, add labeled hotspots when you need more than one destination, and reach for a code hook only when interaction logic demands it. Keep labels clean, keep links outside the bundle, and you’ll ship banners that pass checks and stay easy to maintain.
