Yahoo Site Explorer Showing Different Counts For Registered vs. Non-Registered Users from the Search Engine Roundtable is where I reported that Yahoo Site Explorer seems to be showing a lot more linkage data to a logged in user who authenticated their site in Site Explorer as opposed to a user who is not registered with Yahoo.

For example, when viewing the linkage data for the Search Engine Roundtable as a guest, I see only 57,146 inlinks to the home page, but when I login under the username that authenticated that site, I see 216,880 inlinks to the home page.

Do you think Yahoo is showing only a sampling of data to non-registered users? Do you think that Yahoo will show complete linkage data to only users who have authenticated their sites?

I created a Sphinn thread for further discussion.
