My company provides web based services on long term (years) contract basis.
My customers would regularly visit my website to access the updates about their account.
But all my customers have noticed that my Google ads banners are showing up on most websites they visit, on top, sides and bottom.
All my customers have agreed that they have never seen my Google Ads before visiting my website and subscribing to my service, recommended by someone or from printed flyers.
Since I am targeting to make a trustworthy customer base initially, I am selling my services at rates my competitors can't match. So if a targeted customer is informed about my service, I am positive that they would go for it while its still on discounted rates.
So I wanted google ads to show my ads to customers who are looking at services like mine, searching with my service keywords etc.
Its a waste to show my already existing customers my company ads.
Kindly please advise on how to set this right.
