I have a website (dynamic real estate website) that has been up for nearly a year, all of a sudden Bingbots are trying to access completely lower case versions of the main pages resulting in 404 errors.
The base url is lowercase but subsequent pages are a mixture.
https://example.com/Houses-for-sale-in-Suburb-STATE-3345.php
I have read up on rel canonical and 301 redirects and since have learned that using uppercase is not a good idea - although I decided to use them because states in my country are expressed in UPPERCASE
I am not sure how to handle this, if I convert all of the uppercase URLs to lower case then the bots will still try to access the uppercase versions.
