Re: I am getting a lot of clicks but no phone calls.
There could be a lot of reasons why you're getting clicks but no phone calls
The first thing I would look at is making sure that your ad text makes it clear exactly what you do and encourages people to call. Using a call to action like 'Call Now!' can help encourage people to pick up the phone.
I'd also recommend checking to make sure that you are using call extensions. These make it a lot easier for people to call your number when your ad shows on mobile phones.
It's a good idea to also check your search terms report, to make sure that you're showing for the right kind of search queries. If there are any terms in that report that are irrelevant you can then ad these as negative keywords to help make sure your ads show in front of the right people at the right time.
Hope this helps!
