Search engine marketing is an application to market your business using paid ads that appear in search engine results pages. Advertisers, when searching for specific products or services, will show advertisers' ads next to the results of this search query for keywords entered by users such as Google and Bing. These ads, often known as pay-per-click ads, come in a variety of formats. Some are small text ads, while others (like Product Listing Ads, also known as shopping ads) are more visual, product-based, and allow consumers to see important information from an important perspective. The greatest strength of search marketing is to allow advertisers to show their ads to motivated customers who are ready to make a final purchase when they're ready to buy. Search engine advertising is one of the most effective ways to reach Internet users searching for products or services. .
