Most creators add UTM tags randomly, breaking analytics or tracking the wrong signals. This guide shows you how to structure UTMs correctly for title tests—using native YouTube links, clean parameter names, and reliable click attribution without third-party redirects.

Quick Start
- Open the Title A/B Tracker and fill in your video brief
- Click "Generate A/B titles" to create two variants
- Copy the auto-generated tracking links with clean UTM parameters
- Paste both links into your description (top 3 lines) or pinned comment
- Wait 48–72 hours, then check YouTube Studio Traffic Sources → External
- Log impressions and clicks per link into the tracker's CTR calculator
Why UTM Parameters Matter for Title Testing
Native YouTube URLs with UTM tags don't affect the algorithm. YouTube ignores UTM parameters for recommendations—they only track user clicks. This means you can test titles safely without hurting your video's performance or resetting momentum.
Proper UTM structure lets you attribute clicks to Title A vs Title B cleanly. Without UTMs, you're guessing which title performed better. With them, you have reliable data to make confident decisions about what resonates with your audience.
The key advantage: no redirects, no shorteners, no external landing pages. Just clean, trackable links that preserve your analytics and give you the click attribution you need.
Step 1 — Understand the UTM Structure
UTM parameters are query strings appended to your video URL. The basic anatomy looks like this: ?utm_source=...&utm_medium=...&utm_campaign=...&utm_content=...
Best practices for title tests
- utm_source: Platform origin (e.g.,
youtube,tiktok,instagram) - utm_medium: Link placement (e.g.,
description,pinned-comment,community-post) - utm_campaign: Video identifier—use a unique slug or ID per video (e.g.,
utm-guide-2025ordQw4w9WgXcQ) - utm_content: The variant identifier—
title_aortitle_b(this is the critical parameter for A/B testing)
What NOT to do
- Avoid generic campaigns like
testorvideo—you'll mix data across videos - Don't reuse the same UTM string across videos—each video needs a unique campaign
- Skip
utm_termunless you're tracking specific keywords (it's optional) - Never use the same
utm_contentfor both titles—that defeats the test
utm_content changes between Title A and Title B—everything else stays consistent.Step 2 — Set Up Tracking Links in the Tool
The Title A/B Tracker auto-generates clean UTMs based on your video URL. Fill in your topic, audience, and goal, then click "Generate A/B titles." The tool creates two variants with distinct angles and builds tracking links for each.

How the tool structures the links
The tool takes your YouTube URL input and appends utm_content=title_a and utm_content=title_b automatically. It preserves existing query params (like ?si=...) and ensures the UTMs are properly encoded.
Copy buttons make it one-click to grab both links. You can also customize the UTM values if you want specific campaign names or additional parameters.

Manual UTM setup (optional)
If you want custom UTM values, edit the generated links before posting. Use a URL encoder for special characters (spaces, punctuation). Keep utm_campaign unique per video and utm_content different for Title A vs Title B.
Step 3 — Place Links Without Breaking Analytics
Where you place tracking links affects visibility and click-through. Choose one location per test to keep data clean. Mixing placements (description + comment) makes attribution harder.
Where to place
- Top of description (recommended): First 2-3 lines visible before "Show more." High visibility, easy to update. Best for most tests.
- Pinned comment: Maximum visibility since viewers often check comments for context. Doesn't clutter your description. Requires comments enabled.
- Community post: Ideal for pre-launch tests or existing videos with steady traffic. Lets you test before the video goes live. Requires subscriber base.
How to label
Use neutral phrasing to avoid bias. Don't say "best version" or "preferred title"—that skews clicks. Instead:
- "Which title works better? Option A: [link] • Option B: [link]"
- "Help me pick: Title A [link] or Title B [link]"
- "Testing two angles: [link A] vs [link B]"
Avoiding redirect penalties
Native YouTube links perform better than bit.ly or other shorteners. Redirects add friction (extra page load) and can skew mobile CTR. Stick with full YouTube URLs with UTMs appended.
Step 4 — Read UTM Data from YouTube Studio
After 48–72 hours, open YouTube Studio and navigate to Analytics → Reach → Traffic Sources → External. Filter by your test date range to isolate the test window.
What YouTube Studio shows vs. hides
YouTube Studio displays:
- Clicks per UTM link: Each unique URL appears in the External sources list with click counts
- Total impressions (video-wide): YouTube doesn't split impressions by link—you'll see one number for the entire video
YouTube Studio hides:
- Individual link impressions: You need to estimate or split evenly based on placement
- Click timing: You see cumulative clicks, not hourly breakdowns
Logging data into the tracker
Copy total video impressions from the Reach tab. Divide by 2 (or weight by placement if one link is more visible). Log clicks per link from the External sources list. The Title A/B Tracker calculates CTR for each variant and shows the winner with confidence intervals.
Look for >95% confidence or >2% absolute CTR difference before declaring a winner. Smaller differences might be noise.
Common UTM Mistakes & Fixes
- Using the same UTM for both titles → Change
utm_contenttotitle_aandtitle_bfor unique tracking. - Adding spaces or special chars → URL-encode parameters; the tool does this automatically.
- Shortening UTM links with bit.ly → Use native YouTube URLs to avoid redirect friction and preserve analytics.
- Not checking External traffic in Studio → UTM clicks appear under Traffic Sources → External, not in the main Reach tab.
- Reusing campaign names across videos → Use unique
utm_campaignvalues (video slug or ID) to keep tests isolated. - Forgetting to split impressions → YouTube reports video-wide impressions; estimate per-link impressions by placement or traffic split.
FAQs
- Do UTM parameters affect YouTube's algorithm?
- No. YouTube ignores UTMs for recommendations and rankings. They only track external clicks.
- Can I use UTMs on TikTok or Instagram links?
- Yes. TikTok and Instagram also ignore UTMs for feed rankings. Follow the same structure:
utm_content=title_avstitle_b. - How do I see which UTM link got more clicks?
- In YouTube Studio, go to Analytics → Reach → Traffic Sources → External. Filter by your test date range and look for the two UTM links.
- Should I use a URL shortener for cleaner links?
- No. Native platform links perform better and preserve analytics. Shorteners add friction and can skew mobile CTR.
- What if I have multiple tracking parameters already?
- The Title A/B Tracker preserves existing params. If your video URL already has
?si=..., it appends&utm_...correctly. - Can I reuse the same UTM campaign across videos?
- Don't. Use a unique
utm_campaignper video (e.g., video slug or ID) to keep tests isolated and avoid data mixing. - How long should I wait before checking UTM data?
- Wait 48–72 hours minimum. Early clicks (first 24 hours) come from subscribers/notifications and don't reflect stable CTR.
