302 Redirect

What is 302 Redirect?

A 302 redirect is an HTTP status code indicating a temporary redirection from one URL to another. Unlike the 301 redirect, which signals a permanent move, a 302 redirect tells browsers and search engines that the original URL will be restored in the future. This distinction is crucial because search engines do not transfer the SEO value, or link equity, from the original URL to the new one during a 302 redirect. Historically, 302 redirects originated in the early HTTP/1.0 protocol, designed to enable websites to temporarily redirect users without affecting indexing or ranking of the original content. In e-commerce, this is particularly relevant during seasonal campaigns, flash sales, or temporary product page changes where URLs need to point to alternate pages temporarily without losing the SEO benefits accrued by the original pages. Technically, when a user or bot requests a URL with a 302 redirect, the server responds with a "302 Found" status code and the new URL location, prompting the client to fetch the new resource. Because search engines treat 302 redirects as temporary, they maintain the original URL in their index. This behavior impacts marketing attribution, as tracking systems relying on URL parameters or page paths may need to account for these temporary redirects to accurately attribute conversions or traffic sources. For example, a Shopify store running a limited-time promotion that temporarily redirects a popular product page to a campaign-specific landing page would use a 302 redirect to preserve the original product page's authority and SEO ranking. In the context of marketing attribution platforms like Causality Engine, understanding the use of 302 redirects is essential for correct causal inference of marketing campaigns. Misapplication of 302 redirects can disrupt URL tracking, fragment attribution data, and obscure the true impact of marketing channels. Properly implemented, 302 redirects facilitate smooth user experience during temporary page changes while preserving the integrity of data used to measure marketing effectiveness, thereby supporting data-driven decision-making for e-commerce brands.

Why 302 Redirect Matters for E-commerce

For e-commerce marketers, the correct use of 302 redirects directly impacts SEO performance, user experience, and the accuracy of marketing attribution. Since 302 redirects do not transfer link equity, using them incorrectly can cause a temporary loss in organic search rankings, potentially reducing traffic and sales revenue. For example, a fashion brand running a limited-time collaboration might temporarily redirect a product page using a 302 redirect. This ensures that once the campaign ends, the original page retains its search engine rankings, preserving long-term ROI. Misusing 302 redirects as permanent redirects risks diluting SEO value and undermining organic growth. Moreover, 302 redirects affect marketing attribution tracking by altering URL paths and parameters. Attribution platforms like Causality Engine rely on clean, consistent URLs to accurately assign conversions to marketing channels using causal inference methodologies. If a 302 redirect is misconfigured, it can fragment session data, leading to inaccurate ROI calculations and suboptimal budget allocation. Using 302 redirects strategically also offers a competitive advantage by enabling e-commerce brands to execute agile marketing campaigns—such as flash sales or geographic targeting—without sacrificing SEO or attribution accuracy. In essence, mastering 302 redirects helps e-commerce marketers optimize both customer experience and data-driven marketing decisions.

How to Use 302 Redirect

1. Identify Temporary URL Changes: Use 302 redirects when you need to temporarily redirect traffic from one URL to another, such as during limited-time promotions, flash sales, or A/B testing product pages. 2. Implement Redirects on Your Web Server or CMS: Depending on your platform (e.g., Shopify, Magento), use built-in redirect tools or server configuration files (like .htaccess for Apache or nginx.conf for NGINX) to set 302 redirects. For Shopify stores, the admin interface supports URL redirects where you can specify the redirect type. 3. Test Redirects Thoroughly: Use tools like Screaming Frog SEO Spider, Google Search Console, or browser developer tools to verify that the 302 redirect is functioning correctly and that the status code is properly returned. 4. Monitor SEO and Attribution Metrics: Track performance metrics through Google Analytics, Google Search Console, and your marketing attribution platform (e.g., Causality Engine) to ensure that traffic, rankings, and conversion data remain stable. 5. Revert Redirects When No Longer Needed: Since 302 redirects are temporary, remove or revert them once the campaign or temporary change ends to restore the original URL's direct access and maintain SEO integrity. Best practices include avoiding 302 redirects for permanent URL changes and clearly documenting redirect mappings to prevent confusion. Common tools to assist include Screaming Frog for audits, Google Tag Manager for tracking URL changes, and Causality Engine for assessing how redirects impact marketing channel attribution through causal inference.
