SEO won't survive if used improperly. For instance, Google might mistakenly think that the use of multiple domains pointing to one website is an attempt to manipulate rankings. In such a case, your site could get banned. This includes using "exploitation" tactics like copying content from stores such as Uniqlo's Taobao flagship store to interfere with search results rankings. Most websites that incorrectly use redirection techniques don't end up with business success. A minor misdirection can lead to all previous SEO efforts being wasted, requiring the process to start anew: re-applying for new domain names, relaunching websites, etc. Remember, Google will never tolerate anyone, even those who unintentionally make mistakes.
When performing a 302 redirect from URL A to URL B, the web server indicates that URL A may change its mind at any time and either display its own content or redirect elsewhere. In most cases, most search engines, when encountering paid submission listings, will prioritize URL B.
As video sites rapidly develop, the richness of video content resources continues to grow. How to optimize video site content for search engine indexing has become an increasingly important issue. Research shows that ideas used in optimizing text-based website content for search engines are also applicable and meaningful for video content retrieval.
In general, when handling 302 redirects, it's sufficient to fetch the target URL (in this case, URL B). If search engines consistently follow the 302 redirect to URL B, they will reliably fetch the content from URL B.
