After some 2 weeks of no updates in Alexa ranks of the sites that I monitor, I'm now seeing some very strange things happening.
The ranks of many of the sites have plummetted by around 1 million places. One has fallen 3.5 million places, and another has dropped off the face of the earth as far as Alexa is concerned and has gone from a rank of 4.4 million to No Data, which is a fall of at least 5.6 million places.
And as on a few occasions before, one of my sites gets a different rank depending upon which page you visit.
I guess it's possible that these positions are a result of my robot visiting he sites every day, but it's unlikely.
Anyway, after a short discussion about Alexa on a forum, I've decided it's not really worth bothering about, and I shall be uninstalling the Alexa toolbar.
A week or so ago, I saw the August 2007 results for search engine popularity. Google wins hands down. Of 61 billion searches worldwide, 37 billion were handled by Google. That's more than the other search engines put together.
From today, I'm just going to concentrate on getting my sites highly ranked in Google.
