Hey Hardik, Not sure if this could be he case - Do you also add KWs that remotely relevant to your campaigns from the search terms to the campaigns? If that is the case, these decrease could be because of those KWs, they could be very broad search terms, and since they have been added to the campaigns, they are using up the budget and the leads from these KWs could be irrelevant. This could also result in overall decrease in search impression share because of the high volume of those broad KWs that you might have added.
