One of the most enduring misconceptions about search engine marketing is that whomever has the largest advertising budget wins. Although a larger advertising budget can certainly be advantageous, especially when targeting highly competitive keywords, but it’s far from a requirement for success with search engine marketing. This is because all ads go through a process known as the ad auction before appearing alongside search results. For the purposes of this explanation, we’ll be focusing on the ad auction in Google AdWords.
Social networking sites such as Facebook, Instagram, Twitter, MySpace etc. have all influenced the buzz of word of mouth marketing. In 1999, Misner said that word-of mouth marketing is, "the world's most effective, yet least understood marketing strategy" (Trusov, Bucklin, & Pauwels, 2009, p. 3). Through the influence of opinion leaders, the increased online "buzz" of "word-of-mouth" marketing that a product, service or companies are experiencing is due to the rise in use of social media and smartphones. Businesses and marketers have noticed that, "a persons behaviour is influenced by many small groups" (Kotler, Burton, Deans, Brown, & Armstrong, 2013, p. 189). These small groups rotate around social networking accounts that are run by influential people (opinion leaders or "thought leaders") who have followers of groups. The types of groups (followers) are called: reference groups (people who know each other either face-to-face or have an indirect influence on a persons attitude or behaviour); membership groups (a person has a direct influence on a person's attitude or behaviour); and aspirational groups (groups which an individual wishes to belong to).
Simply put, search engine optimization (SEO) is the process of optimizing the content, technical set-up, and reach of your website so that your pages appear at the top of a search engine result for a specific set of keyword terms. Ultimately, the goal is to attract visitors to your website when they search for products, services, or information related to your business.
Digital marketing poses special challenges for its purveyors. Digital channels are proliferating rapidly, and digital marketers have to keep up with how these channels work, how they're used by receivers and how to use these channels to effectively market things. In addition, it's becoming more difficult to capture receivers' attention, because receivers are increasingly inundated with competing ads. Digital marketers also find it challenging to analyze the vast troves of data they capture and then exploit this information in new marketing efforts.
Facebook pages are far more detailed than Twitter accounts. They allow a product to provide videos, photos, longer descriptions, and testimonials where followers can comment on the product pages for others to see. Facebook can link back to the product's Twitter page, as well as send out event reminders. As of May 2015, 93% of businesses marketers use Facebook to promote their brand. A study from 2011 attributed 84% of "engagement" or clicks and likes that link back to Facebook advertising. By 2014, Facebook had restricted the content published from business and brand pages. Adjustments in Facebook algorithms have reduced the audience for non-paying business pages (that have at least 500,000 "Likes") from 16% in 2012 down to 2% in February 2014. 
Sending emails to your prospective customers for the purpose of educating them on your products and services, and ultimately getting them to do business with you is email marketing. Email marketing can be an incredibly useful marketing tool, given that most adults use email regularly, sending emails is free, and emails can include images, text, and even video of your offerings. While you can easily write and send emails to one or even a small group of people, you will typically need an email marketing tool to help you build more professional and elaborate email campaigns, and to send them to a large number of recipients. These tools can also help you track the results of the emails so you know what is working for you.
9. Richer Customer Experiences. Social media, at its core, is a communication channel like email or phone calls. Every customer interaction you have on social media is an opportunity to publicly demonstrate your customer service level and enrich your relationship with your customers. For example, if a customer complains about your product on Twitter, you can immediately address the comment, apologize publicly, and take action to make it right. Or, if a customer compliments you, you can thank them and recommend additional products. It’s a personal experience that lets customers know you care about them.
YouTube is another popular avenue; advertisements are done in a way to suit the target audience. The type of language used in the commercials and the ideas used to promote the product reflect the audience's style and taste. Also, the ads on this platform are usually in sync with the content of the video requested, this is another advantage YouTube brings for advertisers. Certain ads are presented with certain videos since the content is relevant. Promotional opportunities such as sponsoring a video is also possible on YouTube, "for example, a user who searches for a YouTube video on dog training may be presented with a sponsored video from a dog toy company in results along with other videos." YouTube also enable publishers to earn money through its YouTube Partner Program. Companies can pay YouTube for a special "channel" which promotes the companies products or services.
In the 1990s, the term Digital Marketing was first coined,. With the debut of server/client architecture and the popularity of personal computers, the Customer Relationship Management (CRM) applications became a significant part of marketing technology. Fierce competition forced vendors to include more service into their software, for example, marketing, sales and service applications. Marketers were also able to own huge online customer data by eCRM software after the Internet was born. Companies could update the data of customer needs and obtain the priorities of their experience. This led to the first clickable banner ad being going live in 1994, which was the "You Will" campaign by AT&T and over the first four months of it going live, 44% of all people who saw it clicked on the ad.
