We need someone to manage our adwords account. You will be responsible for liaising with us too see which keywords we wish to be placed on top. You will make our adverts appealing. You will make our adverts mobile friendly. You will submit a report every friday advising where we should spend more/less and revamp keywords as and when necessary. You are required to ensure that you monitor our spend and ensure our CPC remains low and coversions are high. Tell us how experience and what you will offer. We are new to this so dont know whether you will charge a % or a fixed fee.
