Index fragmentation

naexpert asked
Last Modified: 2021-04-21
We have a table with a number of indexes inc a primary key (int). The table rows are being update a lot. Why would the Primary Key become fragmented? it's running at 61% but has been up to 98% fragmentation. I can understand why the other indexes would become fragmented but why the PK? Do you have any suggestions on how the fragmentation can be minimised?  We need the indexes to speed up the read part of the process.
Any pointers would be most welcome.....
