Hello Moz.
We have a law firm client who practices criminal defense law. Historically, he has been ranked for _years _in the map pack and first page of search for a variety of phrases. This is a law firm with twice the number of reviews of the next competitor, solid back links, and open 24 hours a day.
Over the past 30 days, he now appears inconsistently in the map packs. Sometimes he is in the C slot and sometimes he does not appear at all. Most of the time he is not listed for specific legal phrases for DUI, DWI and criminal defense.
When he is not listed in the A, B, or C slot, then he is actually gone completely. You click on More Places and his listing for the map is just completely gone. You can scroll down from listing 1 through 20+ and not find his firm in the Map listings. You would think he would just be further down on the list at 5 - 10. But it is just missing.
However, when you change the filters for either rating or reviews, he suddenly will appear. In fact, he will be near the top of the list, but only on filtering. You can even clear the filter and he stays listed in typically the C slot too. However, if you refresh the page, he is gone again.
My question is simple: Do you think there is some type of data issue or penalty in place? Or is this just how the filters work - suddenly showing a list that should appear in the main area.
PS: If I am not clear on the above, I can send video evidence of this oddity.
