As a form of effective online advertising, PPC works by displaying your company’s ads right in front of online users whenever they use search engines and type the specific keywords you target. Unlike search engine optimisation, you don’t have to wait several days or weeks to see your brand or company name in ads on the first page of search engines like Google, Yahoo!, Bing, and others. AdWords Remarketing, on the other hand, allows your ads to follow a user who has visited and left your site so long as they are still within the Google Display Network. This makes it easier to remind users to go back to your site or call you directly even if they’re already browsing other sites.
