My strategy is to update the pages and I rank better. But I do not modify the page: I add text at the bottom (or in the middle). If I have to create a page that describe a category where there are 10 products, then I start creating the page describing only 5 products. After one month I add some text at the bottom that describes the 6th product, after another month the 7th products and so on .... and I get benefits.
