This upgrade has been made so that e-commerce products can perform better in the search engines by simply making better use of the e-commerce shop product name and short description. This isn't really search engine optimisation, just good web page building. Each product page should contain relevant keyword and description information which relates to that page only. This upgrade has been made as part of the 'Maximum title length' option.
META KEYWORDS are created automatically by comma separating the product name. So a product name "Big Blue Widgets 240V" becomes "Big,Blue,Widgets,240V" - limited to 15 words.
META DESCRIPTION is created from the Product short description but is truncated to 25 words.
These, along with the title, could be used to make all pages different so search engines may index them all instead of only keeping a few indexed.
To turn this option on, set the 'Maximum title length' option to 64 characters inside the Site Administration menu.
