Re: How to improve my bussiensss.....................
I think you're concerning about conversions for your business. To improve your conversion rate I would suggest you to perform following things:
Make separate campaigns for search and display networks.
Analyse your Search Term Report to check whether you're getting clicks from relevant search queries/keywords.
Use proper match types such as Exact Match, Braod Match, Braod Modifier, Phrase Match and effective use of Negative Keywords also.
Write more apealing ad-copies with all benefits and superior services/qualities of your products.
Improve your QS and CTR.
Optimize your Landing Page for better user experience.
I think this will work for you as of now and once you start improving you can make your own strategies to better optimize your campaigns.
