The Zeigarnik Effect in Marketing: How Open Loops and Progress Keep Customers Engaged

Zeigarnik and open loop techniques

What the research says

The original finding

Zeigarnik observed that people tended to recall interrupted tasks better than completed ones. The idea became well known in psychology and later in marketing and storytelling.

Mixed replications

Later research has not always found the effect, and results depend on the task and motivation. Use it as a design idea and test it in your own context.

Progress and goals

Usability research, such as Nielsen Norman Group's guidance on progress indicators, shows that people are more patient and more likely to continue when they can see how far they have come and how much is left.

Motivation matters

An open loop only works if people care about the outcome. A cliffhanger about something irrelevant is easy to ignore.

How to use the Zeigarnik effect ethically

1. Add progress indicators to every multi-step form or checkout.
2. Give new customers a head start ("You have already completed step 1").
3. Create an onboarding checklist with clear, achievable steps.
4. Use series content with a clear next episode.
5. Remind people of unfinished actions they started (with consent).
6. Make it easy to finish, and easy to stop.
7. Test whether progress cues improve completion in your analytics.
8. Never invent incomplete tasks or create anxiety to force action.

Original open loop content templates

• Reel hook: "We almost lost our biggest client because of one email. Here is what happened." (finish in the same video).
• Series: "3 mistakes UAE brands make with Meta ads. Mistake 1 today, mistake 2 tomorrow."
• Email subject: "Part 2: the pricing change that doubled our enquiries" (only if true).
• Onboarding: "Your store setup is 60% complete. Add your logo to finish."
• Loyalty: "2 more visits to your free coffee."
• Quote form: "Step 2 of 3: tell us about your project."
• Webinar: end with one open question answered in the follow-up email.
• Rule: always close the loop you open.

A worked example

Picture a Dubai fitness studio whose online trial sign-up has a long single-page form. It splits the form into three short steps with a progress bar, pre-fills the first step from the class the visitor chose, and shows "Step 2 of 3: choose your time". After sign-up, new members see a checklist: book first class, download the app, meet your coach. On Instagram, the studio runs a five-part series, each episode ending with a teaser of the next. The team compares sign-up completion and first-class attendance before and after. (Illustrative example.)

The goal gradient

A related idea is the goal gradient: people tend to speed up as they get closer to a goal, which is why loyalty cards with a couple of stamps already filled can feel motivating. Combine a head start with a clear finish line.

Open loops in sales

In sales emails, ending with a specific question ("Shall I send the two options we discussed?") leaves a natural loop that invites a reply. Vague endings like "let me know" close nothing and are easy to ignore.

Keep it respectful

Open loops should create curiosity, not stress. If a message would make a customer anxious or feel tricked, rewrite it. Trust lasts longer than any single click.

How Husbar helps

Husbar designs funnels, onboarding flows and content series around how people actually behave, using progress cues, open loops and other behavioural principles, and tests what improves completion.

Questions to ask before you start

• Which multi-step tasks do customers abandon?
• Do our forms show progress?
• What could a new customer's head start be?
• Could we turn our content into a series?
• Do we always close the loops we open?

Key terms

• Zeigarnik effect: the tendency to remember unfinished tasks.
• Open loop: an unresolved story or question.
• Progress indicator: a bar or steps showing how far someone has come.
• Goal gradient: people speed up as they get closer to a goal.
• Onboarding: the first steps a new customer takes.

Mistakes to avoid

• Clickbait loops you never close.
• Fake "incomplete" messages.
• Progress bars that jump backwards.
• Too many steps that feel endless.
• Making it hard to opt out.

Why lead generation needs a system, not a campaign

One good month of leads is luck. A steady pipeline comes from a system: a clear offer for one ideal client, two or three channels that reach them, a page that converts, fast follow-up and weekly measurement. Build the system once and every month gets easier.
