Alexa can be injurious to your wealth

  1. Alexa is also prone to manipulation. It’s stunning to think that someone would actually use it to value a web property. I can’t understand why anyone would use it as more than the most general gauge of traffic trends.

  2. Nice writeup Om – I tell ya – I can probably count over 100 proposals that came to me for some network or ad that someone wanted to run when I ran the Internet Marketing Dept at a Fortune 100 – just amazing how many talked up their Alexa ranking.

    I never trusted Alexa for anything, and still don’t. I know of sites that have 100x my traffic, yet my Alexa is better. Just makes no sense.

    To the uninformed, it looks like a great tool because it is backed by Amazon. Who wouldn’t believe Amazon?

  3. Nice article. I have also noticed that Alexa has too much downtime. off late, it’s getting worse.

    Anyways, I have found Google Analytics extremely useful in analyzing website traffic and making improvements to the website. It’s also free.

  4. Panel based approaches not only suffer from inherent biases and large margins of error, they fail to utilize the key advantage the Internet has over traditional media – direct measurement of media consumption and audiences.

    Quantcast is an alternative to Alexa’s toolbar-based audience measurement. We offer a free Internet ratings service with rankings for over 20M sites and demographic audience ratings for over 1M.

    We quickly realized that the panel based approach in isolation was limited and developed a complementary approach that we call the Quantified Publisher program. Through this free service we directly measure a site’s audience using a measurement pixel. This lets publishers respond to inaccurate published ratings with an accurate third party measurement, and gives them control over how the information is presented.

    Example of Quantified Publishers include The Nation (quantcast.com/thenation.com), TechDirt, (quantcast.com/techdirt.com), Download Squad (quantcast.com/downloadsquad.com) and hundreds more.

    We’re still in beta, but believe we are making great strides towards demystifying the measurement of audiences and creating a resource of open, transparent data that will benefit publishers and advertisers alike. As each new site registers, our model for all sites becomes more accurate.

  5. Hey Om,

    I definitely agree with your view on the inaccuracy of the Alexa ranking system. One thing to point out, however, is that as the ranks increase, they inherently become more and more accurate.

    Just something to note…

    Cheers,

  6. Om,

    I have seen you at times pull data from comScore. So how does it compare with Alexa ? I had asked if comScore had an API but they said they won’t let cannibalization of their data.

  7. Most VC’s, big media buyers have hitwise subscription (30k+ per yr) which is much more accurate and i am sure they also look at the actual logs before commiting anything.

    IMHO, bloggers are those that quote alexa the most!.

  8. Quite an indictment of a free and generally useful service. Seems ironic you would criticize anyone for providing unreliable information, being a provider of similarly unreliable information yourself:

    1) Alexa does work with Firefox. I’m using it right now via the search quick plugin.

    2) Who says Amazon operates Alexa’s website? Check the IP address and domain registration, if you know how, and you’ll see it’s hosted at UnitedLayer.

    3) Alexa has lengthy disclaimers describing how Alexa usage may differ from general Internet usage. Perhaps you could add a disclaimer to your blog indicating that your statements may differ significantly from the facts.

    Lastly, I see you use sitemeter to measure your own traffic. Why not publish your own numbers as a step toward the utopian world in which everyone gets to know everyone else’s site traffic?

  9. In my opinion Quantcast is a lot better indicator than Alexa, and provides some interesting data. Nothing’s been done with Alexa for the last 3 years. It’s time to move on.

    Of course, quantcast is showing very low numbers for a lot of popular sites on Web 2.0. However this may be an indicator that we at the cutting edge of Web 2.0 may actually be a very small community indeed.

  10. News Flash !!!

    An Alexa toolbar DOES work in Firefox.

    http://www.quirk.biz/searchstatus/

    I’m shocked people like Dvorak don’t know this, and people take his word for it eagerly.

    Granted, this new revelation doesn’t fix all the problems with Alexa. But advertisers have been using the Neilson ratings for decades, which are also fallable.

    The point is we need something to hang our hat on, and no rating system is perfect.

  11. Om, great points, indeed. I experienced that a lot: “wow, you’re so high on Alexa” or: “well, you don’t seem to be growing” (while we are growing). More importantly than IE/FF dilemma though:

    1. Alexa exists in ENGLISH and most people on the Internet no longer speak Englih or are native English speakers
    2. Alexa is very much scewed towards North American traffic (check the ranking of some huge Chinese megaportals on it)
    3. Alexa ranking depends on page views and many sites are built in such a way that not all page views are “created equal”
    4. Alexa measures the “Web 2.0” crowd VERY well, but not the general public

  12. Chris, Quantcast looks interesting but I compared my site’s data on our internal logs and Google Analytics (which is almost 100% in sync) and Quantcast – and Quantcast is off by… 20 times!!!! :))) What are these guys smoking? 🙂 Alexa is many times more reliable, sorry.

    Quantcast has some really cool stats some of which are wacky and some are… TRUE! how do they get it beats me…

    Anyway, a curious site, worthwhile looking at but they have long way to go to have any credibility compared to Alexa.

    Cheers

  13. Ig,

    Put the Quantcast measurement pixel on your site, and we’ll show you an accurate number for global and US users.

    Our panel estimate – for US alone – is 400,000 users per month (Alexa doesn’t even give you a unique user count, or the option to correct the numbers).

  14. Oh I have seen the so called results of Alexa rankind first hand with my own blogs – and just as with technorati there is a MASSIVE fault towards non english blogs just to start something.

    My german blog has rougly 15-20 times the hits than my english one and still Alexa lists the english one as much more authorative.

    Just as with IE, the plugin has to be installed and to be working – something I doubt for firefox. Just because I do have a google search field in my Firefox does not mean it does provide the same user data to google than the optimized IE toolbar.

    I do not mind if somebody takes those numbers into account additional to other data- but not alone just based on that.

  15. om,

    i’ve written a number of posts on this

    alexa is unreliable, but i still like to look at their numbers

    for free data, compete, snapshot.compete.com, is the best

    and i think comscore is the gold standard and they are beginning to offer startups their dashboard service at very attractive prices.

    bottom line is i visit all three and rely on comscore when money is on the line.

  16. We recently launched a public and free version of Compete(dot)com to offer a more intelligent service to the market.

    I want to thank Fred for his earlier comments, but want to add that many of the top web operations in the market use Compete’s Intelligence services and consider Compete the gold standard. Within the U.S. Compete has the largest and most diverse panel and applies a rigorous normalization process to make the data representative of the U.S. internet population.

    As far as an API, it’s coming soon.

    Thanks, TJ

  17. I was further saddened when I discovered that Text Link Ads used Alexa for their inclusion algorithms… meant some sites had to cool their heels for a bit before being included, regardless of actual traffic. Oh well!

  19. but I still am amazed is the number of people who use Alexa as a fiscal crutch.

    Or for anything! If you make decisions based on data, your decisions are only as good as your data. That Alexa can be gamed has been known for years i.e. Alexa is bad data.

    Solutions like Hitwise are much better for comparing site traffic, as you can see upstream and downstream data, top referers etc. etc.

  20. Alexa is FREE, Comscore & Hitwise are not, hence it’s easier for most people to use this flawed service than to access the high fee-based services. Not prudent, but accessible and that counts for a lot.

  22. First, there is site down time for Alexa, as discussed in the article, but the bigger issue for many people is Alexa being down (or not calculating) for individual sites. Of my approximately 15 sites, Alexa will often have 2 or 3 at any one time in which it will not show rankings for.

    Second, the article is wrong about Alexa not being able to track Firefox users. The SearchStatus Firefox extension shows Google PR and Alexa ranking for sites. As it is built off of the Alexa API, it provides your visit/page information to Alexa the same way that the Alexa toolbar does. http://www.alexa.com/site/help?index=127

  23. Here’s another article on the same issue – Are you misusing Alexa Numbers? (Probably):
    http://andrewchen.typepad.com/andrewchensblog/2006/11/areyoumisusin.html

    Basically the key points are:
    – Alexa doens’t give pageviews or uniques, just “rank”
    – Alexa’s audience is biased
    – Alexa gives false certainty

    And the finaly question there is, how can we do better? There’s some summary of how Nielsen and comScore approach the problem.

  24. Here’s another thing to think about… I remove LOTS of spyware from customer machines, generally using Spybot S&D. I also install SpywareBlaster, and some other tools. This stuff ALWAYS removes Alexa (along with a lot of other bad stuff). How much do you guys think this might affect the numbers? Do the more common AV/anti-spy solutions do this too?

  27. Alexa takes in consideration that most people do not have alexa tool bar installed. Lets say that you have an Alexa Tool Bar installed and vistit a website, Alexa will not only tally a click for you but will throw in a few clicks to offset the people who are not represented by having an Alexa Toolbar Installed. Lets face it, the only people who care about Alexa are those who need it for advertising or bragging rights. The average person does not care to have what is considered “spyware” on their computer.

  28. I’m surprised to learn that anyone was using Alexa for looking at a site’s page rank! I’ve always used it to check the backlinks for a website and to check who’s really linking to people wanting to link to my site.

    Yes, I know there are other tools for that – but Alexa let’s me see ‘who you’re really sleeping with’ before I accept just any link. Had Google tell me that my natural health site was in the sandbox because a site linking to me (natural health care) was actually linked to ‘get on the xxxxxxpornbandwagon’. My server didn’t catch it, Alexa showed every link that site ever had.

    Thanks folks, but for snooping – Alexa is my pick of the week:)

  30. Indeed, Alexa’s cock-eyed “ping-data” can hurt a start up website. My back end stats say that we say that we get 2-300,000 request per DAY – which can mean around 15-25K views (per day). If Alexa cannot access my ISP – how can they possibly hope to report this kind of info by pinging my site?? Thats comedy. Just let me now when the CLASS ACTION LAWSUIT happens. They owe me a few bucks.
