We're looking into removing the file extension from our web pages. In this case, removing the .asp from the URL.
A few questions that I'd appreciate your opinion on -
1. Is there any negative impact to making this change with regards to search engines?
2. Should we expect a drop in ranking while Google re-crawls?
3. If we do this, should we change all internal linking to remove the .asp?
Thank you in advance for any answers.
