Thanks for the quick response! I do not know what I was looking at earlier. Even doing a review of my browsing history, I cannot find where my eyes deceived me. Sorry about that.
Hopefully, I am not deceiving myself again. I believe I have run across a concern that I thought I'd be able to modify myself but now I see that the source code is hidden.
The issue is that there appears to be an inconsistency with the category chosen by MSU to include within the singular URL for a multiple linked product. Do I have any control over how MSU makes its category choice for the default URL? It doesn't appear to be based upon master category or product/category sort order. I'm unsure how MSU determines the category to use within the URL. If I can remove the category/subcategory path from the URL entirely and just go with an URL based upon the product name, that would be perfect. i.e.
http://www.mystore.com/macintosh-1501.html.
Hopefully, I can get Magic SEO working well enough to the client's satisfaction. He'll dislike the inclusion of category and product ID numbers but will live with that. But I do not know if he will accept the inconsistency of what category is used in a product's URL. Besides, there is a method for us to include any of that info in the product name for SEO purposes (which I go into further below).
The reason I went with Magic SEO is because of the comparison claims of Magic vs. Ultimate, especially in the areas of: HTTP 301/Moved Permanently, Redirections from ALL original ZenCart URLs, Prevents home page duplicate content penalties, Does not add any SQL queries, and Does not break any installed Add-ons, Modules or Templates/Themes. I want to stick with Magic, but my client may override me and live with the short-term penalties of the above issues until product data stabilizes.
FWIW, I had thought there would be an interface allowing choices for whether or not to include manufacturer name, category, model, name, ID(s), etc. in the URL. Basically, I expected an improvement upon Ultimate SEO. Perhaps that requires some really sophisticated coding and commands a price point that would turn away so many as to not be worth the effort or creates SQL queries you are avoiding. But if not an interface then at least limited open source code which would allow for customization. After all, Zen Cart is open source. Magic could be licensed to allow modification.
Oh, wait, msu_tweak is open code and has some options... Nope, that didn't work as expected. I thought setting category depth to 0 would make the URL contain only the product name like Ultimate SEO. I prefer a slashless URL based upon the product name, anyway. Because I can easily adapt all product names to contain the info I want them to contain. The products table has been customised to include fields for mfr, sku, model, submodel, style, substyle, size, color, etc. and can be easily programmed to generate on-the-fly product names to display in the title, in emails, in invoices, in new product listings, search results, featured product listings, individual product info display, etc, leaving products_name in the products description table to exist for SEO mod purposes. Or vice versa.
