Link Tracking and Link Alias in SFMC: Know Which CTA Gets Clicks

An email we audited recently had five different CTAs - hero banner, inline product, text link mid-body, bottom button, footer social links - all pointing to the same homepage URL. The tracking report showed "100 clicks on homepage." Useful? No. The team couldn't tell which CTA was pulling weight and which to optimize.

Link Aliases solve this. Set one per link, even when URLs are identical, and tracking reports break the clicks down by source.

How to set Link Alias

Two methods, both produce the same tracking data.

Method 1: Content Builder Tracking Alias field

When you insert a link via the drag-and-drop editor, there's a field called Tracking Alias (sometimes shown as Link Name). Put a descriptive name there:

Keep the naming consistent across sends so trend analysis works.

Method 2: HTML alias attribute

If you're writing HTML directly:

Same effect as Method 1.

Where to read the data

Email Studio > Tracking > Click Activity tab > Link View.

Table lists each alias with click counts, CTR, and unique clicks. Compare aliases across one send (which CTA worked this time?) or across sends (which CTA design trends higher?).

Email Overlay View

Same Click Activity tab, toggle to Email Overlay View. SFMC renders the email and color-codes each link by click volume - darker = more clicks.

Better for client presentations than raw numbers. Shows the client that the top-right CTA is quiet while the hero button is loud, all without needing to read a table.

Naming conventions that scale

After a few dozen sends, inconsistent alias names make analysis painful. Conventions we use:

Keep positional prefixes consistent so tables sort logically. Version suffixes (_1, _2) for repeated elements like product cards.

Mistake 1: No alias, duplicate URLs collapse

Two CTAs in the same email both link to /products. Without aliases, tracking merges them under one URL entry. You know the URL got clicked; you don't know which CTA drove it.

Always set an alias when the same URL appears more than once.

Mistake 2: Confusing Link Tooltip with Link Alias

Link Tooltip is the text that appears on hover - cosmetic, for subscribers. Has nothing to do with tracking.

Link Alias / Tracking Alias is the internal label used in reporting, invisible to subscribers.

These are separate fields in the UI. Setting Tooltip does not set Alias.

Aliases across Journey sends

In Journey Builder, the email used in a Send Email Activity keeps its aliases - tracking reports per Activity show the same link breakdown. Useful for journey optimization: find the step where CTR drops and inspect which alias underperforms.

Aliases and dynamic content

If you use Dynamic Content Blocks with different links per audience segment, set aliases on each variant. Otherwise tracking merges across variants and you can't tell which dynamic version drove the clicks.

Benchmark: what "normal" CTR per alias looks like

Rough ranges from production data:

• Hero button: 1-2% of opens
• Product card individual: 0.3-0.8% of opens
• Text link in body: 0.1-0.3% of opens
• Footer social: < 0.1% of opens

Anything far off these is worth investigating. Hero button at 0.2%? Weak copy or design. Text link at 2%? Something unusual about the offer or placement worth replicating.

Takeaway

Link Aliases take ten seconds to set per link and unlock per-element CTR reporting. Without them, you know clicks happened; with them, you know which CTA pulled. Set the convention early in the engagement - retrofitting aliases across 50 existing emails after the client asks for "which hero performs best" is a bad day.
