Search Engine Marketing is a method of marketing a business through a paid advertisement that appears on search engine result pages (SERPs). Advertisers bid on specific keywords, that they think will be searched by their user base. This allows your pay-per-click (PPC) ads to appear alongside the results corresponding to the search queries. The biggest advantage of PPC marketing is that it offers the advertisers to put their advertisement in front of the interested customers at the exact precise moment when they are searching for it. No other advertising medium has the ability to do this, which is why SEM is so effective. But if implemented inappropriately it can lead to lost fortune. With many auctions campaign present to bid on, it can be quite confusing to choose the right platform. Also, businesses often waste their budget on a campaign that does not produce the expected results. It can be a trouble for small businesses to choose the most suitable campaign and bid on the right keyword.
