"RuffRuff 予約販売" helps reduce the lost sales opportunities that arise when items are out of stock, before a new product launches, or while waiting for restock.
It lets you implement pre-orders on your own Shopify store with remarkable ease, letting you register unlimited pre-order products and accept unlimited pre-orders. It can also prevent pre-order products from being ordered together with regular products in the same order, and can send back-in-stock notifications when the restock date is undecided.
It also has many unique features not found in other pre-order apps, such as a "deferred payment" feature that lets you collect payment before the product ships.
Improving conversion rate is one of the key challenges in running a Shopify store. Among the many tactics available, popups are known as an effective way to grab visitors' attention and prompt them to take action. This article explains the benefits of displaying popups and introduces Shopify apps that let you display them.
What Is a Popup?
A popup refers to a small screen or window that suddenly appears while browsing a website. A popup opens in a new window or tab separate from the main web page, and is often intended for advertising or promotion. It's commonly used for promoting products or services, or announcing campaigns. Used appropriately, a popup can be an effective way to provide information and promotions, but overusing it risks harming the user experience, so caution is needed.
Benefits of Displaying Popups
Grabs Visitors' Attention
Because a popup suddenly appears on screen, it can forcibly grab a visitor's attention. Compared to ordinary banner ads, it has higher visibility, making it possible to reliably convey important notices or campaign information to visitors.

Makes It Easier to Collect Email Addresses
By using a popup to promote the benefits of subscribing to your newsletter, you can boost your subscriber count and expect to collect a large number of email addresses. By leveraging the email addresses you've collected, you can run effective email marketing.

Contributes to Higher Conversion Rates
By showing an attractive popup at the right moment, you can prompt a variety of conversions, such as product purchases or requests for materials. For example, showing a popup that announces a limited coupon to a visitor who looks like they're about to abandon their cart can help prevent cart abandonment and improve the purchase rate.

How to Display Popups on Shopify
Using a Shopify Theme
First, here's how to use a Shopify theme. Some Shopify themes provide a section that can display popups. The benefit of displaying a popup banner via a Shopify theme is that it incurs no additional cost. The drawback is that you can't finely customize things like display timing or design. Check whether your current theme can display a popup!
Using a Shopify App
Next, here's how to use a Shopify app. Compared to a Shopify theme, it offers greater customizability in terms of display timing and design. On the other hand, it comes with a monthly fee. Check whether a Shopify app can achieve what you want to do, and consider how much you're willing to pay per month for it.
Customizing the Source Code
There may be cases where you still can't achieve what you want even by using a Shopify app. In such cases, you'll need to customize the source code of your Shopify theme.
The benefit is that you can build it for free and freely customize the design. The drawback is that it requires programming knowledge such as HTML, CSS, and JavaScript. Beyond the initial development, it also requires ongoing maintenance, such as time to test that it behaves as intended and to swap in different banners.

Key Points for Using Popups Effectively
Display Them at the Right Timing
Displaying a popup at the right timing is important. By analyzing visitor behavior, you can boost your conversion rate by showing a popup right before a visitor is about to leave, after they've stayed on the site for a certain amount of time, or when they reach a specific page — displaying it at the right moment.
Think Carefully About Appealing Design and Copywriting
Be mindful of appealing design and copywriting. Use a design that matches your brand image, and be sure to keep things consistent. Convey a clear, concise message that grabs visitors' attention. Emphasize perks or discounts, and craft copy that prompts visitors to take action. Optimize the popup's size and placement, and be careful not to harm the user experience.
Optimize Through A/B Testing
Optimizing through A/B testing is also essential. Create popups with different designs, copy, and layouts, and run A/B tests. Analyze how visitors respond and identify the most effective popup. It's important to continuously improve your popups based on test results to boost your conversion rate. You'll need to keep testing regularly to adapt to changing user preferences.
Summary
Using popups on your Shopify store contributes significantly to improving your conversion rate. The apps introduced in this article let you easily create and display popups.
