If a site has 100 units of link equity and offers 10 sitewide categories then each category gets 10% of the link equity. If that same site limits its number of sitewide categories to 5 then each category gets 20%. By being a webmaster who tracks results one of your biggest advantages you have over webmaster who do not track results is you can limit your navigational selection to suit your financial goals. Is something hot this season? Rotate in the featured category or featured products. Is a category unprofitable or far beyond the authority needed to rank for it? Place less emphasis on it.

The nice thing about template sites with includes and dynamic websites are that it is easy to quickly change your weightings to place more focus where the revenue is. A few #6 or #10 ranking pages in the good section suddenly going to #1 might mean 3x to 5x the earnings.
