1. Usually, the cost of domain name transfer is more expensive, and it takes longer, the specific time varies from platform to platform, while external domain push spends shorter time, generally can be completed in the same day.
2. Transferred-in domain's registrar interface will be changed, while the external domain push will not. For example, if a domain name is external pushed from InternetX, then the domain's registrar is still InternetX.
3. External domain push is not supported by all platforms, and not all extensions are supported, so despite the price advantage, but there are certain restrictions.
