The only part of the SEO mod that takes a bit of time, assuming your store contains no mods that have to be re-applied into the SEO-related pages, is creating the custom 404 error page.  I like to do that as the very first step so that when I install the SEO pages, that part is done and waiting for me.

 

In a live store, the way to accomplish the second step (moving the home.asp to the root) with the minimum of customer impact is to retain all of your navigation linkage pointing to /productcart/pc/home.asp etc.  That means there is probably a file in the root (such as index.html or default.html) that redirects to the /pc/home.asp page.

 

Now begin performing the home page move, knowing that nobody will try to get to the root version of home.asp because they don't know it is there.  When you know that it is working, download and then delete that current (root) home page (default.html or index.html as mentioned above) with the redirect, then rename the root home.asp to default.asp or index.asp, whatever your server is set for as a default document.

 

Be sure to note that when you move the SEO-altered pages to the root, that you will need to insert your "/productcart/pc/" or "/store/pc/" path into the <a href= tags wherever you see a reference to <%=pcStrPrdLink%> as this is the new file path which the SEO mod generates.
