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.

Digital marketing's development since the 1990s and 2000s has changed the way brands and businesses use technology for marketing. As digital platforms are increasingly incorporated into marketing plans and everyday life and as people use digital devices instead of visiting physical shops, digital marketing campaigns are becoming more prevalent and efficient.

Digital marketing methods such as search engine optimization (SEO), search engine marketing (SEM), content marketing, influencer marketing, content automation, campaign marketing, data-driven marketing, e-commerce marketing, social media marketing, social media optimization, e-mail direct marketing, Display advertising, e–books, and optical disks and games are becoming more common in our advancing technology. In fact, digital marketing now extends to non-Internet channels that provide digital media, such as mobile phones (SMS and MMS), callback, and on-hold mobile ring tones. In essence, this extension to non-Internet channels helps to differentiate digital marketing from online marketing, another catch-all term for the marketing methods mentioned above, which strictly occur online.

Search Engine Optimization (SEO)

This is the process of optimizing your website to "rank" higher in search engine results pages, thereby increasing the amount of organic (or free) traffic your website receives. The channels that benefit from SEO include websites, blogs, and infographics.

There are a number of ways to approach SEO in order to generate qualified traffic to your website. These include:

On page SEO: This type of SEO focuses on all of the content that exists "on the page" when looking at a website. By researching keywords for their search volume and intent (or meaning), you can answer questions for readers and rank higher on the search engine results pages (SERPs) those questions produce.

Off page SEO: This type of SEO focuses on all of the activity that takes place "off the page" when looking to optimize your website. "What activity not on my own website could affect my ranking?" You might ask. The answer is inbound links, also known as backlinks. The number of publishers that link to you, and the relative "authority" of those publishers, affect how highly you rank for the keywords you care about. By networking with other publishers, writing guest posts on these websites (and linking back to your website), and generating external attention, you can earn the backlinks you need to move your website up on all the right SERPs.

Technical SEO: This type of SEO focuses on the backend of your website, and how your pages are coded. Image compression, structured data, and CSS file optimization are all forms of technical SEO that can increase your website's loading speed -- an important ranking factor in the eyes of search engines like Google.

• Social Media Marketing for Businesses 

Social media marketing is a powerful way for businesses of all sizes to reach prospects and customers. Your customers are already interacting with brands through social media, and if you're not speaking directly to your audience through social platforms like Facebook, Twitter, Instagram, and Pinterest, you're missing out! Great marketing on social media can bring remarkable success to your business, creating devoted brand advocates and even driving leads and sales.

• Pay-per-click (PPC) marketing is a complex digital marketing channel. It presents a significant opportunity for digital marketers to grow their traffic and conversion metrics. But without a smart strategy and careful tactics, pay-per-click can cause major headaches.

• Pay-per-click (PPC), also known as cost per click (CPC), is an internet advertising model used to drive traffic to websites, in which an advertiser pays a publisher (typically a search engine, website owner, or a network of websites) when the ad is clicked.

• Pay-per-click is commonly associated with first-tier search engines (such as Google Ads and Bing Ads). With search engines, advertisers typically bid on keyword phrases relevant to their target market. In contrast, content sites commonly charge a fixed price per click rather than use a bidding system. PPC "display" advertisements, also known as "banner" ads, are shown on web sites with related content that have agreed to show ads and are typically not pay-per-click advertising. Social networks such as Facebook and Twitter have also adopted pay-per-click as one of their advertising models.
