We have online suppliers directory website which has approx. millions of pages & categories. On existing website all categories pages can be browsed through navigation & their category/sub-cate/sub-cate-1 etc.. But on redesign website we are not going to link each supplier page or category on the website through navigation, (we just display most popular one & some sidebar navigation) but all pages are live publicly on server or inside search. User can find those pages when hit any keyword in search.
My question is still will Google crawl & index each page on the website in-spite of each category page would not be linked back on the website?
Awaiting for your reply.
