Can you name Google’s top ten products? If you look at how Quantcast ranks Google’s subdomains, you can get a sense of which Google products are the most popular, since they each have their own subdomain. Google’s main search engine tops the list with an estimated 136.6 million unique visitors in the U.S. Then comes Google Maps (36 million), Image Search (31.7 million), and Gmail (10.5 million). Google Docs, Sites, and Knol are still too small to make the top-ten, but are all showing decent growth.
YouTube, Blogger, and Orkut are not included below because they are on their own domains, but YouTube would be second with 70 million unique U.S. visitors, and Blogger would be in the top 5 with 23.5 million. Orkut is not popular in the U.S., so it would not be a factor in this particular list. And I took out sorry.google.com, the domain Google uses to try to catch bots and spyware. It would have ranked No. 8.

Another notable trend that Quantcast measures is the rise of Google Book Search, which it claims surpassed Google News in visitors back in September. Perhaps the enhanced newspaper archive search features it introduced back then helped. Book Search visitors are now at 8.4 million vs. 7.4 million for Google News, according to Quantcast. Other measurement services such as comScore and Compete show Google News to still be bigger than Google Book Search. ComScore for instance shows Google News at 15.6 million unique U.S. visitors in November, compared to 7.8 million for Book Search. But both also show significant growth in Book Search visitors since the summer.
The Quantcast numbers are not completely reliable because Google’s sites have not been “Quantified” (the process Quantcast uses to collect its most accurate data). But they are roughly accurate. Below the Quantcast rankings, I’ve put the comparable rankings from comScore for U.S. visitors. Some of the rankings are different, but nine out of same products make it on each list. (The only difference is that comScore counts Google Product Search, while Quantcast counts Google Groups).

haha funny my favorite among these is sorry.google.com
Lol yeah… I went to it but it just redirected me back to Google (iGoogle, in my case.)
You may come across the Google bot page when using a public proxy to search.
Nice article, man Google is number 1. Look at those traffic.
Google.com , images.google.com are my favourites!
I couldn’t think of a better starting point for tech startups for look for biz ideas, especially ones which will generate decent ROI, or look fundable to angels and VCs.
Maps, images and mail. Pushing the envelope a little on any of those 3 areas will reel in a winner, instead of just another Twitter API app. Goodness knows we have enough of those…
Book search above news search? Hmmm… Otherwise, looks about OK.
Btw, is this a new feature by quantcast? (Tracking subdomains)
Wow. The speed of drop off is incredibly quick. maps and images are both linked directly from search which is probably what keeps their numbers up.
Is Google a one trick pony?
I had the same thought after going thru the list.
Google.com shows up as 100% in the list!!
Google Books addition of a few back issue magazines – notably Popular Science & Popular Mechanics has me digging through their archives as of late.
Google Maps used more than Gmail? That’s interesting.
Consider that many people use Gmail as a relay and may not actually register a visit to a Gmail page. For example, how is the iGoogle Gmail widget tracked?
Also consider that a page with a Google Maps mashup may record a site hit (not sure I’d call it a visit but that’s a metrics quibble) to retrieve the data. This could explain difference between the two subdomain rankings.
from the point of turning on my system i dont know how many times i visit google search,thats became a part and parcle of my life, what ever i gotto know just go to google thats what i know and ofcourse the services provided them are really fabulous, no wonder google search topped among the websites, what wonders me much is sorry.google.com’s place

ola xk mandais estas cosas no inportanetes
o google daqui a pouco vai possui uns milhares de dominios que no nome interessante sorry
What is ap.google.com ? Never heard of it and going there redirects me to google.nl
I tried ap.google.com, and like you I went to the google front page. However, I noticed that in my search history I had an old link to a page on that site.
When I went there it pulled up a news article from the “Associated Press” that was “Hosted by Google”. Well sort of, the article was expired and not longer available. There was also a link to “Go to Google News”. This makes me think I originally got to this page through Google news and makes me wonder whether this traffic should be added to Google news traffic.
I find it odd that finance.google.com is not listed in the sub-domain report stats.
It seems Google Maps is quite popular in United States. I didn’t think that it could be so popular. In Asia, I don’t think it is used to soften.
Yeah, we are all so google-addicted. Sometime back I realised that I was even not typing the URLs in the address bar or using the click on bookmark but typing the names of websites in google which is a much longer route….so even for opening my favourite websites I first open google search and then go for them…what an idiotic thing to do….
I find that Google searches increasingly come up with links to books in Google Books, which might be another reason for the increase in traffic to the Books subdomain
Interesting. I bet I’m not alone in that I’ve never used anything other than #1 on the list…..I didn’t even know some of those things existed.
I’m on the opposite end, power. I’m wondering why I depend almost exclusively on Google for search, calendar, mail, etc.
Something’s fishy:
calendar.google.com doesn’t show at all?
I could care less for this google subdomain traffic list.
I want to see google’s subdomain list by revenue!
It’s interesting that there is no mention of AdWords, AdSense, Analytics, Webmaster Tools, etc. These are tools I use numerous times throughout the day, as do many webmasters, developers, site owners, marketing personnel, etc. Those are really the bread and butter behind the revenue. These products listed are merely avenues to plant the ads in and get them in front of the consumers.
These features do not have their own subdomains. They are all directories on the Google root.
If you stop and think about it, a subdomain requires a fresh DNS lookup, which can slow down a user. So there are plenty of successful products (e.g. google.com/webmasters/ ) where Google uses a subdirectory and avoids the latency of another DNS lookup.
very good
Is Reader on a subdomain? usage numbers there would be very interesting.
google.com includes search, reader, analytics…and what else?
Is it possible to get a break-up of these?
The comparison with Yahoo’s subdomains is quite interesting:
http://www.quan...m/traffic/sites
It doesn’t get to < 1m users until page 3.
I think the basic problem is that most of people are not aware of these services from the google.
I was also not aware of all of these services from the google.
I would have thought Gmail would be higher on the list. I like Google image search a lot as well…
Shame there is no individual data on the usage numbers of iGoogle.
I wonder just how many people in the USA use iGoogle as their own Start Page Dashboard.
I’m interested to know from TC folks what is the last search engine they used before they switched to Google permanently.
I would have thought Gmail would be higher on the list.
what is that bot catcher all about?
What about igoogle?
Interesting research. It is surprisingly fact that google map was more popular compare to the Gmail. I would tought Gmail have more users, with simple assumptions follows:
[-]. Google Map is mostly used by publishers, while Gmail is used by both publishers and non-publishers. Comparing email users and publishers, i don’t think number of publisher is bigger compare to email.
[-]. Using Google Map consume a huge of internet bandwidth. Particullary for 2rd country, internet bandwidth is a significant cost.
Is this a sign that map usage is getting more and more popular on the internet world of 2009 (e.g.; Google Map will become a must tools for travellers)?
Thanks for sharing!
The results looks OK, not too suprised.
I’m interested to know from TC folks what is the last search engine they used before they switched to Google permanently.
Shouldn’t the title of this article be “Google’s Top Ten Products (More Or Less) in the US ?”
Is there any similar studies based on worldwide records?
No doubt, Google Rules Internet! Easy user interface and continuous innovation has driven this tremendous growth.
However, who do you think can replace Google? What do you think would be future of organizing information?? Please comment on this at my blog.

@Erick: I believe your “Google’s main search engine tops the list with an estimated 136.6 million unique visitors in the U.S.” statement in incorrect. That figure for google.com is for the *whole domain* (i.e. aggregate of all subdomains), and not just for the search engine part of http://www.goog....com/google.com. That is how Quantcast works.
Great article, quite informative… thanks!
Where is google shop search http://www.google.com/products ?
I think it is more popular than sites.google.com
i deadly loyal to google sites, knol, and page creator. hope it grows steadily.
