If you provide great information that can't be found anywhere else or common information that is presented in a way far superior than anywhere else
Have actually done this - got a load of data and presented it well, my competitors ignored it's public availability. It answers a "what is " question, over 2,000 extra pages linked in to our own data so thats 6,000 extra pages, yet currently probably creating 30% of the traffic !
Now have a new 1 million plus rows database answering another series of similar questions, still working out how to present it.. :)
