we are a smartphone ,tabs and laptop sale and service centre , we have an existing adword account but its not responding as it should be on the repair keywords , google policies are not clear on brands and 3rd party technical support , or what we we need is a trick , the competitor ads do show up. whats your fair view on this ? are the other ads temporary show ups . can you give your audit report , can you do it ? our website www.tougheestelecom.in , a hint keyword "iPhone repair delhi" so we are looking for somebody whom we can trust and show result , better for us that if the interested one can come to our setup and work. we see people calling them as digital marketing experts but dont show results. so if you are the one who can do it , give me a call.
