scenario, the Blue Widgets page would link to the Home page, Almond Widgets page, Cyan Widgets page, 1/4″ page, and 1/2″ page. The 1/4″ page would link to the 1/2″ page, the Blue Widgets page, and the home page. So let's see how this weight passes: Home page pass: 25 for himself 25 on page almond widgets 25 on Page Blue Widgets 25 on Page Cyan Widgets The almond widgets page passes: 6.25 to home page 6.25 for himself 6.25 on page Blue Widgets 6.25 on page Cyan Widgets The Blue Widgets page goes: 4.17 homepage 4.17 on page almond widgets 4.17 to himself 4.17 on page Cyan Widgets 4.17 to 1/4″ page 4.17 to 1/2″ page The Cyan Widgets page passes: 5 to home page 5 on page
almond widgets 5 on Page Blue Widgets 5 to himself 5 on page 1″ 1/4″ page passes: 1.04 to homepage 1.04 on the Blue Widgets page 1.04 for himself 1.04 to 1/2″ page Page 1/2 "passes" 1.04 to homepage 1.04 on the Blue Widgets page 1.04 to 1/4″ page 1.04 for himself Page 1″ passes: 1.67 to homepage 1.67 on page Cyan Widgets 1.67 for itself Which gives us a final value fax number list of: Home - 144.17 Almond Widgets - $40.42 Blue Widgets - 42.5 Cyan Widgets - 42.09 1/4" - 6.25 1/2" - 6.25 1" - 6.67 We can see here that the sinking PageRank spreads the weight across the major category pages, reducing the weight passed to the individual sizes of the colored widgets and the homepage. In the majority of site structures, this is the desired scenario.
The question we might ask, however, is why we want a structure where the individual metrics in the most populated category (Blue Widgets, in this case) have a lower value. You might wonder, wouldn't it be better to spread out the categories to shift weight to more categories at the top level and fewer pages below? Let's look at a basic example: PageRank linear flow. So using the same structure as above (pages passing weight to others in the same size grouping, the one above and the homepage: Home page pass: 20 for himself 20 on page
