I am running a customer support campaign. Here conversions are to tends to no. of calls. customers visit our site and pick up the number and give us a call. In this case how I can check which keyword is giving more conversions? If you have more clicks that doesn't means you have large number of conversion. May be that particular keyword leads to be generating less number of conversions but getting more clicks /traffic So how can I check which keywords have higher potential for my campaign?
