I currently use the following format for several of the links in my navbar:

example.com/widgets.php?t=1

But now I want to use mod rewrite so that the format is like:

example.com/most-recent


Before I make the change, I wanted to ask if this will cause any ill affects with Google? They change their algorithms so many times each month that I can never keep up with what they deem good and bad.

Thank you!
