What Is a Website Custom Audience? Visitors, Segmented by Depth

In plain English

Built from pixel and Conversions API data: all visitors, visitors to specific pages, or people who triggered specific events.

Segmenting matters. Someone who read a blog post and someone who reached the checkout are not comparable prospects, and treating them as one audience wastes the difference.

What to know

From pixel and server events

Site activity.

Segmentable by page and event

Depth of interest.

Time-windowed

Thirty days behaves differently from one hundred and eighty.

Reduced by tracking limits

Smaller than it once was.

Why it matters

The highest-value retargeting audience is usually people who reached a decision page and did not act. Building that one specifically is more effective than retargeting all visitors.

Common mistakes

×One audience of all visitors.

×Windows so long that interest has expired.

×No exclusion of converters.

×Assuming coverage matches actual site traffic.

FAQs

What window should I use?

Short for high-intent pages, longer for general visitors. Test both.

Why is my audience smaller than my traffic?

Browser privacy features and blockers reduce what can be recorded.
