What type of page should my Category Pages and Product Pages be?

[Osman]

Should they be static collection pages? and should the collection data be cached or static?

Also, considering the prices of the products will be updated regularly as it is a price comparison site would the static page collections make sense or would the have to be dynamic?

If you’re using static collection page, then your collection needs to be static, but won’t be filterable.

In your case, I’d suggest using dynamic pages
