SOLVED IT!
The problem:
Treeview uses inter-module communications and postbacks, making it very difficult for bots to crawl the products.
Solution:
o I created another page, didn't list it in the menu.
o Used a free module called SQLGridSelectedView (allows you to display/edit tables)
o Set it up with the following query:
SELECT
'<a href="https://www.MySiteName.com/Product_Details/ProductID/' + CAST(ProductID AS VarChar) + '/' + SEOUrl + '.aspx">' + ModelName + '</a>' AS LinkURL FROM Smith_Products
o Created an "invisible" (white on white) html link <a href="/Home/ProductLinks.aspx">.</ >
... so, now when the bot comes around, it hits that hidden link, gets a list of all the products in the cart, and crawls all my product pages.
(patting myself on the back a little on this one)
