Shopify's 'Unexpected Redirect' Protection: What Merchants Need to Know

Shopify recently introduced a new security feature that displays a warning message to customers when they click a link that leads to an external website. This protection is automatic and designed to improve shopper safety across the platform by giving them a moment to confirm they intend to leave your store.

What is Shopify's new protection against unexpected redirects?

This protection is a confirmation prompt that appears after a customer clicks a link on your store that points to a domain outside of Shopify. It serves as an alert, making the customer aware that they are about to navigate away from the familiar environment of your shop to an external site.

The feature is not an error message but a deliberate security checkpoint. It functions as an interstitial page, pausing the navigation process and asking for the user's consent before proceeding to the destination URL. This simple step helps reduce the risk of users unknowingly landing on potentially harmful websites.

This differs from browser-level warnings, like a red "Deceptive site ahead" screen, which indicate a known threat. Shopify's prompt is a platform-level notice, not a sign that the destination is malicious. It is designed to create a consistent, predictable checkpoint for shoppers, training them to pause and verify before leaving any Shopify store.

For merchants, this means any link in your content, such as in a blog post or on a product page, that directs shoppers to a third-party site will now trigger this warning. It is a universal change applied by Shopify to standardize security expectations for all customers on the platform.

When does this confirmation prompt appear for customers?

The confirmation prompt is triggered whenever a customer clicks a link that directs them away from a Shopify-controlled domain. This includes any external URL you might have in your product descriptions, blog articles, or custom pages built within your Shopify theme.

The warning appears before the browser loads the new site, acting as an intermediary step. It intercepts the click to ensure the user’s action is intentional. This happens only for links that lead to destinations not hosted by Shopify. Internal links to other products, collections, or pages on your own store will not trigger the warning.

Similarly, navigation within the standard Shopify ecosystem, such as proceeding to checkout or accessing the customer account portal, remains unaffected. The feature is specifically focused on the transition from a Shopify-hosted storefront to any other site on the web.

An edge case: JavaScript-based redirects

What if your store uses JavaScript to redirect users, not a standard link? For example, a script might redirect a user to a different page based on their location. These client-side redirects, often using `window.location.href`, will also trigger the warning message if the destination is external.

The protection intercepts the navigation request regardless of whether it comes from a direct click on an `` tag or from a script. This is crucial, as malicious code often uses scripted redirects to send users to harmful sites without them clicking a visible link. However, this also means legitimate, scripted redirects to external partners will now have this added step.

This is especially relevant for stores using third-party apps for features like store locators or event calendars. An app might dynamically generate a link to Google Maps based on a user's address input. Even though the app is trusted, the final destination is external. The redirect warning will still appear, which can be confusing if you were not expecting it.

How does this feature protect customers from phishing and malicious sites?

The redirect warning directly counters a common tactic used in phishing attacks. These attacks often rely on tricking a user into clicking a link that looks legitimate but leads to a fraudulent website designed to steal credentials or payment information.

This new feature creates a critical moment of friction. By interrupting the otherwise instant redirect, it forces the customer to pause and consider the destination. The warning page typically displays the full URL of the external site, giving the shopper a clear opportunity to spot something suspicious they might have missed, like a lookalike domain.

Attackers depend on speed and a user's sense of trust in the site they are currently on. The prompt breaks that otherwise uninterrupted flow, effectively holding up a sign that says "You are leaving now." This small delay is often enough to prevent a user from automatically proceeding to a site that is not what it seems.

What it costs when it goes wrong

Imagine a phishing attack succeeds by using a link on your store. An attacker might hide a malicious script in a third-party app, redirecting your customers to a fake payment page that steals their card details. The direct cost to your business can be immense, involving chargebacks, lost sales, and hours spent on incident response.

These costs are not just hypothetical. They include tangible expenses like PCI-DSS non-compliance fines, which can be severe. You may also face legal fees and the cost of providing credit monitoring services to affected customers. Beyond that is the operational drain on your support team, who will be tied up managing angry customers instead of helping legitimate ones.

The reputational damage is often worse. A successful phishing attack can lead to significant financial costs for a small business, even before accounting for the loss of customer trust. A single incident can lead to shoppers avoiding your store and warning others, causing long-term harm that far outweighs the minor friction of a redirect warning.

Are there any legitimate links on your store that this might affect?

Yes, this protection will affect any legitimate link on your store that points to an external domain. The system does not distinguish between a helpful resource and a malicious link; it only checks whether the destination is outside of Shopify's direct control.

Common examples of legitimate links that will now show a warning include those pointing to a manufacturer's website for technical specifications or warranty information. If you link out to a partner's blog, a favorable product review on YouTube, or an industry report, customers will see the prompt for each.

Common legitimate uses for external links

Many stores rely on external links for daily operations. For instance, you might link to a SurveyMonkey or Google Form to collect customer feedback post-purchase. Each of those clicks will now be intercepted by the warning prompt.

If you are launching a new product line via a Kickstarter campaign, links to that campaign page will also trigger the alert. The same applies to linking to press features in online magazines or to PDF user manuals hosted on a service like Dropbox.

Even links to your own off-platform content, such as a separate company blog on a different domain or a public file download, will be impacted. The key is to understand this is an expected behavior, not a sign that your links are broken or considered unsafe by Shopify.

Can you whitelist certain external domains to prevent the warning?

Initially, merchants could not whitelist domains. However, Shopify has since updated the feature. Merchants can now add specific external domains to a "trusted domains" list in their admin settings under Online Store > Preferences. Links to these whitelisted domains will bypass the warning.

This allows merchants to prevent the confirmation prompt for business-critical external destinations they own or trust, such as booking tools, partner portals, or separate blogs. However, Shopify still blocks links to sites it identifies as malicious and may show a confirmation for sites it deems suspicious, regardless of your list.

The trade-off: Platform Security vs. Merchant Flexibility

Shopify's initial decision to block customization highlighted a classic trade-off. Enforcing a universal rule maximizes security for all shoppers by preventing compromised merchant accounts from whitelisting malicious sites. This creates a predictable, safe environment for everyone on the platform.

By adding a trusted domains list, Shopify has shifted the balance slightly toward merchant flexibility. This acknowledges that merchants have legitimate reasons to send customers to external sites. The responsibility now partly falls on the merchant to maintain their trusted domains list and ensure those external sites remain secure.

The risk of a trusted domains list

Whitelisting a domain is an act of trust, but that trust comes with a new responsibility. An external site that is safe today could be compromised tomorrow, or the domain could expire and be bought by a bad actor. Merchants must periodically review their trusted domains list to ensure each entry is still secure and necessary, turning a one-time setup into an ongoing security task.

Does this impact affiliate links or links to your social media profiles?

Yes, the redirect warning will apply to affiliate links and, in some cases, links to your social media profiles. Any link that directs a user to a domain that is not on your trusted domains list will trigger the confirmation prompt before the browser continues to the destination.

For affiliate marketing, this means a click on a link to a partner's product or a tracking domain will be preceded by the warning unless you add that domain to your trusted list. Likewise, while Shopify exempts some major social platforms, links to less common ones or to specific posts might be affected.

A worked example: The cost of an interrupted link

Consider a blog post with a popular affiliate link. Each click represents a potential commission. The redirect warning introduces a point of friction where a customer might pause. If the destination domain looks unfamiliar, some may choose to click back rather than proceed, abandoning the journey you intended for them.

Even a small percentage of users dropping off at this stage can lead to a meaningful reduction in affiliate income over thousands of clicks. For merchants who rely on affiliate marketing for a portion of their revenue, this friction directly impacts the bottom line. Whitelisting trusted partners becomes a critical step to preserve that income.

The issue can be more complex with affiliate networks that use redirect chains. You might whitelist the initial tracking domain, but the user may be passed through several others before the final page. If any intermediate domain is not on your list, the warning could still appear, disrupting the journey and potentially breaking the affiliate tracking.

Is there anything merchants need to do to configure this feature?

The redirect protection itself is automatic, but managing your trusted domains is a new, crucial task. You do not need to enable the feature, but you should actively configure your whitelist to ensure a smooth experience for customers clicking legitimate external links.

The primary task is to identify all essential external domains you link to and add them under Online Store > Preferences. This prevents unnecessary friction for customers heading to your booking tool, partner sites, or other trusted destinations.

Actionable step: Auditing your external links

First, create a complete inventory of every external link on your storefront. Check your navigation menus, footers, product descriptions, blog posts, and custom pages. Some third-party apps can help crawl your site for external links.

For each link, verify that the destination is still correct and provides value. While you're there, ensure all external links are set to open in a new browser tab (`target="_blank"`). This keeps your store open in the customer's browser, making it easier for them to return after visiting the external site.

Finally, build your trusted domains list from this audit. Add only the domains that are essential for your business operations and that you have verified as safe. Regularly review this list, especially after installing new apps or adding new partners, to keep it current.

How does this improve the trustworthiness of the Shopify platform?

This feature improves trustworthiness by creating a more secure and predictable shopping environment for everyone. By implementing a consistent, platform-wide warning system, Shopify helps educate customers about online safety and what to expect when navigating away from a store.

A proactive security measure like this demonstrates a commitment to protecting shoppers from common online threats such as phishing. When customers feel safer, they are more confident in making purchases. This trust extends not just to your individual store but to the entire network of merchants using the platform.

This feature also acts as a form of collective defense. A widespread phishing attack originating from Shopify stores could damage the reputation of the entire platform, hurting all merchants. By making these attacks harder to execute, Shopify protects the shared brand value that all of its merchants depend on.

Ultimately, a standardized approach reduces confusion and helps users develop better security habits. Over time, customers learn that this warning is a normal part of the Shopify experience, making them more likely to notice when such a warning *should* appear but does not on other, less secure platforms.

Trust is the currency of ecommerce. It's built in a thousand small moments, from the first click on an ad to the moment an order arrives as promised. Every feature that makes that journey clearer and safer for a customer is an investment in that trust.

Shopify's redirect protection is a valuable step in securing the customer journey up to the point of sale. It hardens the platform against external threats and builds shopper confidence. However, maintaining that trust does not end at the checkout. A simple mistake, like a customer entering the wrong shipping address, can quickly turn a positive experience into a frustrating one, leading to costly support tickets and delayed shipments.

After Shopify secures the purchase, Tacey helps secure the delivery. By giving customers a short window on the order status page to fix their own address and update contact information, you reduce errors before they become problems. For many order types, customers can even add an item to their order. This self-service capability keeps the customer in control and protects the trust you worked hard to earn.

Frequently asked questions

Will this warning hurt my conversion rate?

Any friction can potentially impact user behavior, but you can minimize the effect by adding essential external domains to Shopify's "trusted domains" list. For links where the warning still appears, the impact should be minimal as customers on the platform grow accustomed to this standard security feature.

Does this apply to links in customer notification emails?

Typically, this type of redirect protection is implemented on the website itself, not within emails. Links in emails sent from Shopify, like shipping confirmations, are generally not affected by this specific storefront warning, though email clients have their own separate security features.

What should I tell customers who ask about this warning?

You can inform them that it is a standard security feature implemented by Shopify to protect them. Explain that it confirms their intent to visit an external site and helps ensure they are not being redirected to a malicious page without their knowledge. Reassure them it is a sign of a secure shopping platform.

Does this affect links to my other Shopify stores?

Yes, if you link from one Shopify store to another store on a different domain, the warning will appear unless you add the second store's domain to the first store's trusted domains list. The system checks if the destination domain is the same as the current one, so even another Shopify store is considered external.

Can I customize the message in the redirect warning?

No, the message and appearance of the redirect warning are controlled by Shopify and cannot be customized by individual merchants. This consistency is a key part of the feature's design, ensuring a uniform and recognizable experience for all shoppers across the platform.
