Sorry I missed this
HTML Code:
in ultimate friendly URLs (not sure how the CEON one works), the anchor and the product id are the only relevant data. changing the product name does not render an invalid URL. and it will still return the correct product page as long as those pieces of information are correct.
CEON produces full text urls like this:
www .shop.com/manufacturers/eazi-grip-racing-products/dash-protectors/aprilia/dash-protector-aprilia-rs125-tuono-125-2014

so an update to a name changes the url
www .shop.com/manufacturers/eazi-grip-racing-products/dash-protectors/aprilia/dash-protector-aprilia-rs125-tuono-125-2021

and the previous one gets stored and used to redirect to the new one.

Anyway a suitable question that generally burns lots of bandwidth would be "what url to use in this plugin?"

Friendly: www .shop.com/widget
or native: www .shop.com/index.php?main_page=product_info&cPath=1_4&products_id=1

or just add another config option and let people choose?

I'm not getting involved in any discussion, others can read everything out there and eventually come up with a short and sweet conclusion, lets not have endless SEO arguments as usual.
