Hi Calvin...Now take about 100 keywords of the 1800 and make PageBomb pages. These will have some static elements. Use these pages to create what we used to call "hallway" pages. Hallway pages are like site maps, their main purpose is to link to other pages.
Each of these pages should link to 25 of your 1800 pages, as well as 20-40 other hallway pages.
With all these pages your goal isn't really to try to get them all to rank, but rather to help your "best" 25-50 pages to rank well. To do this, make sure you link to your "best" 25 or so pages in your templates so these pages get site-wide links.
