Digital marketing is the marketing of products or services using digital technologies, mainly on the Internet, but also including mobile phones, display advertising, and any other digital medium.[1] Digital marketing channels are systems based on the internet that can create, accelerate, and transmit product value from producer to the terminal consumer by digital networks.[2][3]
Organic SEO's flip-side offers up a paid method for marketing on search engines like Google. SEM provides an avenue for displaying ads through networks such as Google's Adwords and other paid search platforms that exist across the web throughout social media sites like Facebook, Instagram and even video sites like YouTube, which, invariably, is the world's second largest search engine.

With the development of this system, the price is growing under the high level of competition. Many advertisers prefer to expand their activities, including increasing search engines and adding more keywords. The more advertisers are willing to pay for clicks, the higher the ranking for advertising, which leads to higher traffic.[15] PPC comes at a cost. The higher position is likely to cost $5 for a given keyword, and $4.50 for a third location. A third advertiser earns 10% less than the top advertiser, while reducing traffic by 50%.[15] The investors must consider their return on investment and then determine whether the increase in traffic is worth the increase.
In some contexts, the term SEM is used exclusively to mean pay per click advertising,[2] particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
Ever heard of Maslow's hierarchy of needs? It's a theory of psychology that prioritizes the most fundamental human needs (like air, water, and physical safety) over more advanced needs (like esteem and social belonging). The theory is that you can't achieve the needs at the top without ensuring the more fundamental needs are met first. Love doesn't matter if you don't have food.

Remember that users enter search words into search engines based on their interest. The matching keywords and phrases you choose for your campaigns help determine if your ad will display when users search online. But be aware, other advertisers may also be using the same keywords. That creates competition with your ad campaign. What can you do to win? One solution is keyword bidding.
The digital marketer usually focuses on a different key performance indicator (KPI) for each channel so they can properly measure the company's performance across each one. A digital marketer who's in charge of SEO, for example, measures their website's "organic traffic" -- of that traffic coming from website visitors who found a page of the business's website via a Google search.
