So I have a store which has been around for a while and is custom built on ASP.net. Store has thousands of sku's and at least a few hundred subcategories.
Have been tackling a bunch of the onsite issues and for categories which have more than 6 products in them, there are multiple pages and a view all present.
Example.com/category
example.com/category?PageIndex=2
example.com/category?PageIndex=3
example.com/category?PageIndex=4
example.com/category?viewall=True
As well as the following for every page
example.com/category?PageIndex=2&viewall=True
So I know how I wish to handle the pagination/canoncial issue as per google's suggestions you do it to the view all or they have the rel=next/prev.
But my question is google says if view all is present they should already do a good job at ranking the view all version. Well in the rankings, there are a lot of page1 variations showing.
So once this is implementated, is it safe to assume that I will see a drop? Feel like if it was a brand new site it is easy but for something this old and established, it could cause some decent harm which at the current time we are already tackling a massive list of issues which in the long haul will improve it.
Looking for some insight for someone who has dealt with ASP.net and this specific area.
thanks
Sean
