Changing a page url

[bhsiao]

I have a page that ranks well (#4) for a good keyword. However, the url has the keyword in it but is misspelled. I would like to change the url to have the correct spelling but do not want to lose the ranking that I have.

What is the best and safest way to proceed?

I think you would be fine to change it so you have the correct spelling - just be sure to 301 redirect the old file name to the new file name after to change it.

Billy is completely correct. Take a look at Moz's Redirection Guide for more information.
