The excellent Kottke.org has a post on Google's search dominance. When working on projects we need data to support our conclusions and rely on sources such as Hitwise, Comscore, Nielsen, etc. I often have serious doubts about the accuracy of the information supplied. Kottke references Comscore reporting search breaking down like so:
- 64% Google
- 20% Yahoo!
- 08% Microsoft
His own stats come out as follows:
- 94% Google
- 03% Microsoft
- 01% Yahoo!
It could be that visitors to Kottke.org fit a certain profile, perhaps not the kind of person who defaults to a portal when they open their browser. With this in mind I took a look at the analytics for a few sites I have access to, including blogs and commercial operations. The results came out as follows:
- 91% Google
- 04% Yahoo!
- 04% Microsoft
I'd be very interested to see figures from other people as this makes it look like Comscore's data is wildly off. I wonder what the explanation could be? From my perspective Google have search completely stitched up and no-one is in much of position to challenge their dominance. The figures show that recent articles about Wolfram Alpha or bing are either written by people with no understanding of search or who are simply keen on attention-grabbing headlines over substance and inquiry.
Update: TorrentFreak illustrates the point I make above in this post: Nielsen Hugely Underestimates BitTorrent Traffic. The inaccuracy of the data from these measurement companies is highlighted by a recent news story from The Age that quotes Nielsen data for visits by Australians to BitTorrent search engines. Apparently mininova provided their statistics so their data could be checked out. Nielsen data turned out to be wildly inacurate with traffic to mininova alone being 600% higher than Nielsen reported to a number of BitTorrent search engines. In conclusion:
Data from measurement companies isn't worth much beyond a vague guide to broad trends
I can't actually find Nielsen saying anything about this directly but my question to them if this is true would be: "Why should we trust any other conclusions you produce if your data is apparently so unreliable?".
Update: I'm honour-bound to point out these results from Hitwise that show Google taking a 90%+ share of search.
Update: please see the comment below from Mark Higginson (not me, another one!) who is Director of Analytics at Nielsen in Australia. He points out that the figures they supplied were not a measure of visits as the TorrentFreak article stated but instead measured 'unique audience', a metric I'm not familiar with. This goes someway to clearing up this confusion but also shows how easy it is to make assumptions about what is being claimed from audience figures that may be being calculated in completely different ways. I really appreciate Mark taking the time to comment on this post and clarify this matter.
4 original comments:
The difference between those figures could be explained by the simple fact that Hitwise, Comscore, Neilsen etc is based on page views yeah? Where as your data and Kottke.org’s data is based on referrals. MSN is the default home page for people with internet explorer. A lot of people can’t be bothered, or don’t know how, to change their home page. So that means every time they open up IE, the MSN home page comes up. They may not use it for search, in fact they may even search for Google in Yahoo or msn/live/bing.
Additionally, people may use Yahoo or Bing, but may not find what they’re looking for and resort to Google.
Numbers are only ever a snapshot of a particular viewpoint, so they could potentially explain the discrepancy.

That’s a very good point because don’t Comscore et. al. collect data from a small sample of individuals with an app installed on their computers? I wonder if this means a ‘view’ is being confused with ‘use of’ as you point out?

Hi Mark,
Mark Higginson in Australia here. Long time between meetings. :-)
I was the one who supplied the figures to The Age in my role as Director of Analytics here at Nielsen Online Australia and part of the issue with the article mentioned was the journalist using the term “visits”. The numbers we supplied were actually Unique Audience, not visits, not even Unique Browsers – and comes from a panel methodology.
So whilst TorrentFreak didn’t know it, the comment in their article “This may sound like a lot of traffic, but since Nielsen reports the number of visits and not the unique visitors we expected it to be much higher” was incorrect. The comparison to the figures that Mininova report isn’t apples with apples – plus Mininova aren’t able to report on Unique Audience – the best they would be able to do is Unique Browsers, which with cookie deletion etc can be widely overestimated as an indication to actual user numbers.

Hi Mark,
Many thanks for the comment and apologies for the delayed response, I’ve had a busy, busy August getting married.
I think what this shows is the confusion around the different measures we employ. I’d favour ‘daily unique visitors’ as a metric I can compare across sites that gives me a good idea of how popular they are in terms of a sustained readership, kind of equivalent to print ABC figures.
What does ‘unique audience’ measure and does anyone else use this? If this is a Nielsen only metric doesn’t this make these kind of comparisons impossible outside Nielsen’s own system of measurement? I’d be interested to hear your thoughts.
All the best,
Mark.
