Use the endowment effect to increase conversions Insight from Kristen Berman.
People tend to value items more when they own them.
That’s the endowment effect—the psychological phenomenon behind why someone is more likely to buy a car after taking it for a test drive. When we feel like something is already ours, we place a higher value on it.
Here are a few ways you can use the endowment effect to convert warm prospects into paying customers.
Reframe promos. Instead of standard promos (and free giveaways), frame them as if they already belong to users.
Adjust cart abandonment copy. Consider using the endowment effect in cart abandonment emails. Use language like “your [product] can’t wait to come home” to help shoppers feel as though they already own the items in their carts.
Create interactive content. Help users visualize products as theirs by adding an interactive component to your site, app, or socials.
2. Use schema markup to drive more organic traffic Insight from Demand Curve.
Here's an underrated SEO technique that can improve click-through rate: schema markup.
Schema markups (also known as structured data) are snippets of code that, when added to your pages, help Google represent your content in search results. ![]()

For certain search types, adding schema can get you more clicks. By giving visitors more insight into your content, it can encourage them to click on your site vs. other search results.
For example, someone shopping for a specific product might click on the result that’s labeled “in stock” based on product schema.
Besides product schema, here are three other types worth adding to your pages:
You can find more details about each type of schema on schema.org.
To create your schema markup, use Google’s Structured Data Markup Helper or another free online generator like TechnicalSEO.com. These tools walk you through the markup process and then provide a code to be added to a specific page’s HTML code.
3. Most tests “fail” Insight from Demand Curve.
Most business experiments—around 90%—result in so-called failure.
Example: an A/B test in which the status quo ends up being the winner.
But those results are just as important as “successes.” They support startup growth by providing insights into:
Instead of defining “failure” and “success” based on test results, here are the definitions we recommend.
Failure: the act of creating 1. an undisciplined test, like one with an untestable hypothesis 2. a test with low impact on your business, or 3. a test your team won't learn from
Success: the act of developing, launching, and learning from a rigorous test with the potential for high business impact
Basically, a sloppy test is a fail. An inconsequential test is a fail. A well-designed test is a win. And any test that gives you useful new information is a win.
So go ahead and “fail.” Encourage your team to do the same. Disproven hypotheses are part of a healthy growth culture.
