About this domain
A factual note on the address
In March 2020 this domain hosted a public tracking study, run by the analytics company MonkeyData, of how COVID-19 was affecting online shops in Central and Eastern Europe; more than 1,200 stores were followed and the figures were updated daily. The domain later expired and carried unrelated content. Shelf & Signal is an independent magazine: it continues the public subject, and it is not connected to MonkeyData or to any of the later operators.
