2009

Google is updating the PageRank-values on their datacenters, just as 2009 is drawing to a close. The roll-out is going on at the moment and some datacenters like 209.85.129.99 or 74.125.1.99 are already showing the new values. Those of you who do not want to wait for the toolbar to […]...

Holding with tradition, my Christmas greetings come rather late but still from the bottom of my heart. I wish a merry Christmas and a few restful days to all of our readers. I am looking forward to next year, where I believe that we will see a lot of interesting […]...

While yesterday’s evaluation was more about the growth (which might have plateaued out or maybe even regressed a little) of Twitter, today, I want to look at how Twitter is being utilized by the user. Just like yesterday, all the following diagrams are based on data extrapolated from about 10% […]...

Just as I said a few month ago, after being rather skeptical in the beginning, I turned out to be a Twitter-fan: many informations that would have passed my by before are now showing up in my Twitter-stream. I do agree that there are a lot of useless informations, too, […]...

When I started this blog, it was purely a newsblog: when Google brought a new data-center online I felt it was worth a post; if there was a Googledance it was newsworthy in any case. This has changed noticeably over the last few years. By now, there are longer posts […]...

The fourth PageRank-Update this year just so fits into October of this year. Last night, Google has, once again, pushed (at least partially) current PageRank-values onto the necessary datacenters. The cut-off-date was especially long ago this time around: it seems to be somewhere around 09/12. Seeing how the last few […]...

Not long ago, I stumbled upon a keyword for which much of the Top-10 Google SERPs were PDF-files. This was rather frustrating in this case because the PC did not have PDF-reader installed and Google’s conversion is usually rather confusing. This made me curious as to the rate that PDF-files […]...

Between the dmexco that ended a few days ago and the SES, which will be held in Berlin this year, I think that the end of October will be a fitting date to host another SEO-regulars-table in Bonn. Everyone from around here who is interested in SEO is welcome to […]...

Another month has passed and here are the current IndexWatch-numbers. Just as a short reminder: these charts are based on our Visibility Index and show the winners and losers of the (organic) Google-index. As usual, we start with the winners:winners # Domain Change   1 linguee.de +1.000%   2 bizrate.de […]...

Most of the conventions and meets before the summer-break are through, which means its about time to hold another SEO-regulars’ table in Bonn. I picked out Thursday the 18th of June for the date. Everyone who is interested in the subject matter and who will not blatantly misbehave is welcome […]...

After having used some diagrams from the SISTRIX Visibility Index in this blog and seeing how the monthly IndexWatch is based on this information, I would like to explain a few things about this value, the idea behind it and the way it is calculated in a bid to make […]...
