Google Advertising, or as it's also known, Google Ads, is Google's own digital advertising tool and has become a world leader in the field. These ads appear at the top or bottom of the page when you perform a search on Google. With Google Ads, you can pay to appear among the first results when someone searches for keywords associated with your ad. The best part is that you only pay when someone actually clicks on your ad. This gives you full control over your Google Ads costs.
