I would like to ask on what is the best to do to compare multiple web pages?
for example, I need to compare, page performance, visits, etc.
I would do that in workspace, there are multiple ways to achieve that, you may find some default templates to achieve that.
By looking at the question I would suggest you to use the Page dimension and use the metric Page Views, visits, bounces, etc.
Feel free to add if there is any specific question you have.
