I am currently working on a site that has core SEO enabled.
Some pages within the same category display several categories in the URL while some display "item"
This can be seen here:
theoraclereviews.com/

The first item on the page resolves to:
theoraclereviews.com/item/30-vacation-with-a-vampire-stay/vivi-and-the-vampire/island-vacation-by-michele-hauf--kendra-leigh-castle-and-lisa-childs

The second item on the page resolves to:
theoraclereviews.com/component/k2/item/29-to-russia-with-love-by-chris-almeida--cecilia-aubrey-countermeasure-#2&Itemid=101


How do I make the SEO URL consistent and also shorter? Is there a way to remove the categories from it? also the "component/k2/item" from the URL?

Thank you,

Flavia
