And the percentage seems to be going up. Probably varies by topic and demographic, though, so general statistics or other people's experiences may not apply to your site....
At my site, a niche information site, once I exclude repeat visitors coming via bookmarks and internal referrals, I'd estimate that 90% of my traffic is from search engines.
My clients get 85%+ of their web traffic delivered either from the "natural" listings or from the advertisments. So I know most of their visitors found them from the SEs. Others are probably returns / responses from OPT IN mail lists.
Right out of the book:
Audience Reach Percentage (ARP) Defined: The percentage of the entire internet audience reached by a particular search engine or search directory over a 30 day period. An ARP of 1 percent would indicate that 1 percent of the total internet audience utilized the search site AT LEAST ONCE within the last 30 days.
ARP for the following sites are
Google 32%
Yahoo! 29%
MSN 27%
AOL 18%
Ask Jeeves 10%
These numbers are HUGE! That means that 32% of ALL THE USERS ON THE INTERNET pretty much use google on a regular basis. Now granted they only have to visit google once every 30 days, but realistically, how many people surf the web and make searches once a month? If you look at the numbers, they add up to more than 100% also, meaning some people use muliple search engines for their searches.
Just my .02¢
