About 80% but I enjoy high search engine rankings and don't have a site targeted to teenagers (little viral traffic).
This is quite a spread - is there a norm? The bulk of my traffic comes from type-ins - visitors who have bookmarked. Just wondering if I should be shooting for a higher percentage from search engines.
Depends of the content. On some of mine sites 95% comes from the search engines, but for instance at online utility Awstats shows only about 10-11% come from SE, 51% direct access, and rest about 38-40% from backlinks.
