On July 27, exactly one month after June 27, one of our larger web sites Multiplex Systems Store regained its position for all competitive sets of keywords. What exactly caused the problem still remains a question, but this is something that is referred to as “data refresh” by Matt Cutts.
As a preventive measure for future, we are launching a static web site GSM Modem devoted exclusively to GSM modems, including GSM/GPRS/EDGE modules, terminals, PC cards and other equipment. The content is not there yet (just the domain) but we plan to add it soon. Initially it will be in Russian, but we may add Ukrainian and English content.
