Today on Webmasterworld there was a discussion about Google showing fewer than 10 organic results for certain searches. I did some checking and was able to see that in fact Google is showing fewer than ten results. It looks like Google is experimenting with displaying other resources they think people may be interested in for certain searches. At the time I checked, most “commercial” terms were unaffected. However, if you were the number 10, or in some cases the number 9 result in the organic listings you may see your site dropped to page two which would have a huge impact on your traffic. Numbers 9 and 10 don’t get a lot of traffic, but page two gets next to none. If you had enough listings at the bottom of the first page that got dropped, you’d see a significant drop in traffic. Every time I’ve seen Google experiment with adding things to the results, it eventually sticks.
Page 1 just got more competitive!
