301 & 302 Jump Difference

301 Permanent jump: When a user or search engine sends a browsing request to a website server, a status code in the header information returned by the server indicates that the page is permanently transferred to another address.

302 temporary jump, is also a status code, meaning temporarily turned to another URL.

The main difference between the two is that 302 is easily regarded as spam by search engines, while 301 is not.
