SEO Weasel says look a bit closer to home when researching Link Devaluation
Can you answer these two questions;
1. . Do you think your search engine rankings would drop if your site navigation was not structured as well as it is?
2. Do you suspect your search engine rankings have dropped because of link devaluation?
If you have answered yes to both of these questions you could be suffering from Internal Link Devaluation
Internal link devaluation is where a website that has unnaturally high search engine rankings primarily due to the fact that pages are strengthened by internal navigation links are returned to their natural position with these internal links discounted.
