Hi Melissa,
I'm starting to get a lot of similar reports so the good news it's not just your listings. I suspect there is either something buggy or there is an update of some sort happening.
Here is what I posted in that thread that Colan linked to: (Thanks Colan)
1st of all Places analytics are pretty hit and miss and I seldom even look at them. They are often buggy so that could be the case here. So if you are still ranking and listing is live and working right, I would not worry too much about the stats.
I'd 1st check to be sure the listing is working right. If you click view from dashboard does it go to the right listing?
Next I'd check to see if the ranking dropped. If it has there are many many reasons that could have happened and we'd need to investigate further.
If you care to post a link and give us more history and let us know if there was a major rank drop and give us one primary key phrase, I'll move this down to help and we can investigate in more detail.
I helped one person at the G forum yesterday that had this issue, but I have not had time to get over there today to see if there are more reports. Also have not had time to check email yet to see if Google emailed me anything about it or if other TCs have asked about it yet.
If I don't find any answers, I'll escalate to Google to see if they will tell us what's up.
Will report back here when I have news.
