Yesterday I commented that the increase in Alexa rank for the various sites that I monitor have been levelling off.
Today's results seem to confirm the theory that you can't push your own sites high by visiting them every day.
On average, the ranks seem to update about every 3 days, so my graphs have a stepped look to them, but the curve is still prominent.
Today's results, after a gap of 6 days with no change, saw one of my sites increae in rank by just 3 places. Not much of a dent on its rank of 2,889,553.
This also confirms my theory that the Internet Marketing gurus give away custom Alexa Toolbars just so that people will visit their sites with the toolbar switched on. I guess the neatest trick would be to produce websites that serve content only if the Alexa Toolbar is running. I don't know if that's possible, but it might be worth looking into.
