I have a 4-5 years old website. I'm thinking of changing the structure of the site. Currently it shows a collection of x number of items on a page.
I want to have a separate page for each item.
This way there could be discussion about one particular item. Social Sharing for the single item. Related items. These features require separate pages. I think it would improve user experience.
The site has around 3000 pages indexed, but after the change, the site would have around 20,000 pages (lot of pages with little content). I'm worried how Google will react.
