you should be able to add unique SEO keywords to individual products, manufacturers, categories, and information pages.
The SEO keywords you add will be displayed in the url of the page, so they must be unique for each product, product category, etc. Let’s see what happens when we add the SEO keyword, “nikon-camera”, to our Nikon D300 product under the Data tab:
If our store is located at “www.mystore.com”, the new URL of the Nikon D300 product page will be located at “www.mystore.com/nikon-camera”. Overall, creating SEO keywords will clean up your store page’s URL and optimize your page for search engines.
