When advertising using search engine marketing sem you only pay – when the person actually looks at your site for more than 5 seconds.
So, if advertising on the Internet, there are a variety of different online marketing techniques: SEO (Search Engine Optimisation), PPC (Pay per Click), and SEM (Search Engine Marketing).
Paid ads can also be found via two other services, which are classified as paid listings and sponsored results. PPC is an online advertising technique that enables advertisers to have their website listed on the first positions in a search engine’s advertising section or on other websites pages, depending on whether it is through pay-per-click (PPC) or pay per impression (PPI).
To avoid a situation where a click on a PPC link can cost you more money than the product or service is worth, SEM enables you to choose the amount of money that you would like to pay for each click, or often per each visitor. Usually, this system of payment is based on the number of times users see your ad and how many times they click on it.
The amount of money that you choose to pay per click depends on the level of traffic that your website receives and the requirements and budget of the product or service advertised through SEM. This means that if people do not view your ad, or if they don’t click on it and visit your web page, no charge is made for that.
