What Is the Impact of a 302 Redirect on Page Authority and Domain Authority Metrics From an SEO Perspective?


A 302 redirect, from an SEO perspective, often does not transfer page authority (commonly referred to as "link juice") compared to a 301 redirect, which can impact both page authority and domain authority metrics. It is essential to understand the implications of using 302 redirects and when to use them appropriately to safeguard SEO performance.

Understanding HTTP Redirects

302 Redirect vs. 301 Redirect

A 302 redirect signifies to search engines that the URL has been temporarily moved to a new location. Conversely, a 301 redirect indicates a permanent move. Search engines typically pass the page authority of the original URL to the new URL in the case of a 301 redirect.

Impact on Page Authority

Page authority, a metric developed by Moz, gauges the likelihood of a single page ranking well in search engine results. When a 302 redirect is applied, search engines usually do not pass the full page authority to the new URL. This is because a 302 redirect tells search engines that the move is temporary, leading them to treat the original URL and the new URL separately.

Case Study Example

For instance, if example.com/page1 redirects to example.com/page2 via a 302 redirect, search engines like Google might continue indexing and prioritizing page1, expecting page2 to be temporary. Hence, page1 retains its page authority, and page2 may not inherit much, if any, of it.

Impact on Domain Authority

Domain authority, also a metric by Moz, measures the overall strength of a domain and its potential to rank. A 302 redirect can indirectly affect domain authority if the proper page authority is not passed and pages on the domain contain less overall authority, potentially impacting the domain's overall rankability.

Search engines rely heavily on internal links to distribute page authority across a domain. If pages linked internally through 302 redirects do not pass page authority effectively, it can result in uneven distribution and an overall decrease in domain authority.

SEO Best Practices for Redirects

Use 302 Sparingly

Reserve 302 redirects only for truly temporary URL changes, such as during A/B testing or temporary promotions. For any permanent URL changes, 301 redirects should be implemented to ensure a smooth transfer of page authority.

Audit and Update Redirects Regularly

Regularly audit your site to identify potentially outdated 302 redirects. Tools like Screaming Frog SEO Spider can help pinpoint these and suggest where a 301 redirect might be more appropriate.

Monitor Search Console for Indexing Issues

Keep an eye on your Google Search Console for any issues related to redirects that might impact indexing. Adjust your redirects based on performance data and recommendations from Google's insights.

Example Tools and Resources

Utilize resources like Google Search Console Help and Moz’s Guide on Redirection to fine-tune your redirect strategy.


In summary, a 302 redirect does not usually pass page authority to the new URL, thereby potentially impacting your SEO efforts. To maximize page authority and domain authority metrics, use 301 redirects for permanent changes and ensure regular audits of your redirect strategies.
