Summary
Remarketing is the data segment that lets the software company reach people who already visited the site but never signed up. It is built from your own Google tag or linked GA4 data, so it targets known past visitors rather than new prospects that Google predicts might be interested.

To bring back people who already visited the software company’s website but never completed the sign-up, the right data segment is Remarketing, which targets your own site visitors through the Google Ads audience list built from your tag.
- Detailed Demographics
- Remarketing
- In-market audiences
- Lookalike
The correct answer is: Remarketing
Key Takeaways
- – Remarketing is the correct data segment for re-engaging people who visited the website but did not sign up.
- – Build the list in Audience manager using a Website visitors rule, then exclude the sign-up thank you page URL so only the non-converters remain.
- – Remarketing is first-party data from your own tag or linked GA4 property, while Detailed Demographics, In-market and Lookalike segments come from Google’s data about the user.
- – Video remarketing lists need enough members before they serve, and membership duration caps at 540 days, so a stale list will stop delivering if you never refresh the rule.
How do you build a remarketing list that only contains visitors who did not sign up?
Create one segment for all website visitors and a second segment for people who hit the sign-up confirmation URL. In the ad group, add the visitors list under Audiences and add the converters list as an exclusion under the Exclusions section. That combination leaves only the users who browsed and left without completing the form.
What data source do you need before remarketing will work on YouTube campaigns?
You need the Google tag firing on the site, or a Google Analytics 4 property linked to the Google Ads account so its audiences import. Check the status in Tools, Shared library, Audience manager, under Your data sources. If it shows No recent activity, the tag is not collecting and no list will fill up.
Is Lookalike the same as remarketing since it is also based on your site visitors?
No. A Lookalike segment uses your remarketing list as a seed and then finds new people who behave like them, so everyone in it is a fresh prospect who has never been to your site. Remarketing targets the actual visitors themselves. For re-engagement the question asks for the original visitors, which is Remarketing.
Why does a video remarketing campaign sometimes show almost no impressions?
Usually the list is too small to serve, or the membership duration is short and older visitors have already aged out. Open Audience manager and check the YouTube size column for that segment. Widening the lookback window, loosening the URL rule, or combining several visitor lists into one usually fixes the delivery problem.
