Some critical notes for what it's worth:
>how realiable you think are those stats?
They can only be based on referral stats, not actual stats. I think one or two sites with high search engine refrerrals joining or not joining onestat.com could considerably influence their data.
Sites with many indexable pages will typically get very different referral data then small sites for example. Ilse's marketshare will be larger then it should be if Onestat tracked small (and/or old) sites more then large sites. Because Ilse hardly ever updates their index they can hardly be compared to engines that do index most of the web.
I would like to see more about the method and actual numbers that were used to reach those conclusions before making decisions based on this data..
Lycos.nl or .com does not appear above AltaVista in my stats. Could be our poor positions with FAST but I doubt it. Onestat has a deal with Lycos, I would not be totally surprised if that somehow inlfuenced Lycos' 5th position.
I'm getting a lot more traffic from MSN to my Dutch sites these days, compared to a few months ago.. About half of Google traffic levels, making it a very strong second in our stats.
Might be due to algo changes or Inktomi indexing more pages of course..
I also see a slight increase in Ilse.nl referrals.. can't really explain it as I don't think Ilse updated anything important to us lately.
