Why does Dapper ask for more than one URL in step 2 of the Dapp Factory?
The more example pages you supply, the better Dapper works. This is because have more samples allows Dapper to determine which elements recur on every page and which data is dynamic. Typically, only dynamic data is of interest, so being able to isolate this data is useful. Good sample pages are pages that have the same structure and layout, but have different content (e.g., search results pages, product pages). If the page you want content from is unique in its layout (e.g., a homepage), you can add just that page. Watch a demo that explains step 2.
