To import independent site reviews into the Walmart platform, sellers need to follow Walmart’s ReviewSyndicationProgram (Review Synchronization Program). Here are the steps and requirements based on the search results:

1. ** Self-built site requirements **: The seller needs to have his own independent site, and the products on the site need to have accumulated a certain number of reviews.

2. ** Review ownership **: The imported reviews must belong to the seller, i.e. the reviews are left for products sold on the seller’s independent site.

3. ** Avoid participating in other review synchronization programs **: On Walmart, sellers cannot participate in other review synchronization programs, such as Bazaarvoice, etc.

4. ** Application Process **: Eligible sellers can submit an application through the link provided by Walmart official. After the application is submitted, the third party responsible for review synchronization will contact the seller directly to follow up the application.

5. ** Application Duration **: Due to the large number of applicants, the entire process of completing review synchronization is expected to take about 8 weeks, but the specific time may vary according to the actual situation.

6. ** Security **: Synchronizing reviews is an officially recognized operation of Walmart, with high security and will not lead to the problem of account blocking.

7. ** Avoid fake reviews **: Walmart encourages sellers to provide the best quality and most affordable products, guarantees an organic consumer retention rate, and puts an end to all fake reviews.

8. ** Review process **: Walmart will review the application. After the review is passed, the seller will receive an email notification.

9. ** Data Synchronization **: Once the review is passed, the seller can synchronize the reviews of its independent site on the Walmart platform.

Please note that the above information may change with changes in Walmart platform policies. It is recommended that sellers carefully read the official guidelines of the Walmart platform or directly consult Walmart’s customer service for the latest operation guidelines before operation. At the same time, sellers should ensure that all operations comply with Walmart’s rules and requirements and avoid violating platform policies.
