We have a moderately big regional site. As of now we have 20,000 pages of great unique content. Every page is linked internally to 20 most related pages. And we get fairly good long tail traffic.
We have 3 big competitors, all of them with sites having millions of pages. (less than 5 million). Most of the pages are made up of tag pages, members profiles pages, search pages etc. This strategy seems to be working for them.
My question: What's our best shot against them? The keywords they cover through auto generated pages are such that if we go by the editorial route we won't be touching those keywords in foreseeable future. But these keywords/keyword-phrases are hundreds of thousands in number. We do believe that we can outrank them based on relevancy.
