The SEO features can be configured through the message catalogs with the attributes beginning with "seo." (e.g seo.default.meta.description or seo.meta.keywords.template). The catalogs contain multi-lingual templates in order to write product information (name, model, manufacturer, category) into:
The URL
The window title
The meta description
The meta keywords
The templates may contain the following placeholders : $category, $manufacturer, $name, $model which are substituted by real data depending on what is being viewed at the time. Each attribute within the message catalog has a description which explains how it is used.
From version 5.7.5.0 the URL formatting is configurable. The default formatting creates a URL with a tree like structure:
/DVD-Movies/Action/Warner/Fire-Down-Below/DVD-FDBL/2_11.action
The other option, selectable from the Admin App (Configuration >> Store Configuration) adds parameters to the URL:
SelectProd.action?prodId=11&manufacturer=Warner&category=Action&name=Fire+Down+Below&model=DVD-FDBL
The source of the code that reformats the URLs is available in the Struts actions of the storefront application.
