Noted that my GA results under Search Engine Optimization (i.e. queries, geo summary and landing pages) for a client accounts have started showing zero results since June 21st. Can anyone provide a heads up as to why this is happening?
The Search Engine Optimization report pulls in data from the Google Webmaster Tools APIs; they don't involve data that Google Analytics itself collects.
Typically, externally imported results (like Adwords API data) typically face a 24-48 hour lag at minimum; occasionally, that lag can be a little longer. But, "0" results" basically just means that the import for that day hasn't happened yet (FWIW, my accounts haven't gotten their 6/21/2012 imports yet either).
