A 302 redirect is an HTTP status code that signifies a temporary redirection of a webpage. It indicates to search engines and users that the current request for a URL should be temporarily directed to a different URL, yet it is anticipated that the original URL will be reinstated or remain the primary endpoint in the future.
Applications in SEO:
In SEO, a 302 redirect is often employed when content is temporarily moved or when a website is undergoing maintenance and the content needs to be temporarily shifted to another URL. It allows the preservation of the user experience by providing them with an alternative page rather than a dead link or a 404 error page.
Unlike a 301 redirect, which indicates a permanent move, a 302 redirect conveys that the change is provisional.
When to use:
A 302 redirect should only be used if the relocation of the content is temporary. Examples include:
- Promotional campaigns where content is temporarily relocated to a dedicated event page
- A/B testing where different versions of a page are being tested
- Site maintenance or redesign, where the original content is expected to return to its original URL
Impact on SEO:
A 302 redirect does not pass the full link equity (ranking power) to the new URL because search engines interpret it as temporary. Therefore, it should not be implemented if the intent is to permanently move a webpage as it may not provide the desired SEO benefits of a permanent redirect.
Best practices:
Ensure that a 302 redirect is implemented properly and only when necessary. Overuse or incorrect usage can confuse search engines and users, potentially harming site performance and rankings:
- Double-check the purpose of the redirect to confirm that a 302 is appropriate instead of a 301
- Monitor the usage of 302 redirects to make sure that they are changed back to direct URLs once the temporary need has been fulfilled
- Communicate to search engines through other signals (such as canonical tags) the preferred URL to be indexed
In summary, within the context of technical SEO, a 302 redirect is a tool for temporarily directing traffic which should be used judiciously to avoid any negative implications on a site’s search engine visibility.
