Why Do Google Hit Numbers Vary?
Craig writes: "Thanks for the great question. We get this from time to time and hopefully I can clear up some of the confusion. The number of estimated pages listed to the top right of a Google search results page is indeed, an estimate. It's a good estimate but still, an estimate.
There are many reasons why one might see a difference in the estimated number of pages returned for the same query. It's most likely the queries made by your co-workers were sent to different Google datacenters in what appears to have been a round-robin fashion. The index at any given Google datacenter can change slightly over the course of a day (each index is refreshed completely every three to four weeks). Depending on which datacenter finishes a query, the estimated number of results may vary.
Without having direct access to your environment it is hard for me to tell for sure, however, I believe this is the case."
About a month ago, someone posted this story over on K5 regarding the google dance. Good to see it's run by a marketing site, I couldn't think of anyone who might have more of an interest in rankings then those bastards. :P
That's because Google doesn't do boolean searches. It will ignore the or (too common a word) and ends up treating it like an and search.
Insert wit here.
Wrong. OR is a boolean operator to Google. Check the "Advanced Search" link.

Ah, but Google does have one....well, available at the Googleplex.
Actually, if you use an uppercase OR, it will perform a boolean search. Otherwise, the search defaults to an AND, unless of course you're using doublequotes "like this" to search for a phrase.
From a vague memory of the last major /. article about Google, don't they have a censored realtime display of searches scrolling behind their reception desk?
;D
And what you're thinking of is Metaspy - it still has that uncensored option.

Uhhh, no. A domain can only see their OWN cookies.

so you may connect to any one of several servers. The servers each have different databases to pool results from and different caches to display.
A google search for my site returns our old site that has had dead dns records for nearly a month above my new site. Sometimes my new site pulls into the lead, sometimes it isn't there, and at least one cache has the announcement that the old name was lost and a domain was purchased.
You can't judge a book by the way it wears its hair.
Results can also vary due to the Google Dance.
Google has 7 data centers each with a copy of it's index and these are "usually" mapped to www.google.com. But google also has versions located at www2.google.com and www3.google.com.
During the monthly update there can be different version of the index on each of the 3 versions. A website www.google-dance-tool.1hut.com provides results for a search done on all 3 of googles index.
To check to see if the google dance is happening the most common technique is to check the "back links" for mayor sites like Yahoo by typing "link:www.yahoo.com" into the search box. this will list all the sites with links to "www.yahoo.com".
The Google Dance Tool site mentioned checks google every 5 minutes to see if the dance is on. Once it is started it sends out an automated email to subscribers (like me) so I can visit the site and see what the search positions for the next month on google will be using their google dance tool search.
Google uses Dmoz as a pagerank source. Just submit your site through Google's forms, I've had stuff listed within 1-2 days.
