PPC stands for pay-per-click, a model of internet marketing in which advertisers pay a fee each time one of their ads is clicked. Essentially, it's a way of buying visits to your site, rather than attempting to earn those visits organically. Google AdWords is a fast and simple way to expand the reach of your website. It's a marketing tool that can offer instant results and huge rewards. It's also highly measurable which means you can make regular adjustments to your strategy in order to improve your results, as Adrian Bold explain.
Simply getting people to visit your website is not enough. You have to make sure the traffic is refined and curated. This is one area where you can really compare website traffic coming from the three different channels. The traffic you get through SEO and SMM is more refined so you have a better chance of converting the visitors.
Pay-per-click (PPC) sometimes referred to as paid search advertising or search marketing, is a practice of online advertising, whereby sponsored links are purchased on search engine results pages (SERP), websites, content sites or blogs. Paid search allows you to pay a fee to have your website displayed on SERP when someone types in specific keywords or phrases to the search engine. The SERP will display the ads that you create to direct viewers to your site. The fee you pay is based on either clicks on or views of these ads. .
