Every campaign has one or more ad groups. An ad group helps you to structure your campaign into groups of advertisements and keywords that are directly related to one another, which can enhance your Quality Score and help you increase your ROI. This helps Search Network campaigns deliver advertisements relevant to the queries of the individuals you're seeking to target. You may design relevant adverts to present to clients exploring websites about comparable themes for campaigns targeting the Display Network. You'll want to build different ad groups for each subject or product that you're advertising, just as you did with your campaign structure. Consider generating ad groups based on the regions or categories on your website once more. For instance, the same electronics store may develop ad groups for sub-categories such as small cameras and SLR cameras.
