Looking at a couple of sites where almost exactly one year after launch, traffic has trailed off by 80% over just the last month. Both have stunted link development, but are gaining links slowly, however their Toolbar PR has been heavily reduced since the last check many months ago, with many grey bar pages. Interestingly, both sites show 99% of all page URLs are still indexed (there's no Duplicate issues at all!). Both show good rankings for many key phrases, especially in local searches, but the traffic has gone. WebmasterTools lists nothing of concern (just three pages with short titles or meta descriptions).
