With offline marketing, it's very difficult to tell how people are interacting with your brand before they have an interaction with a salesperson or make a purchase. With digital marketing, you can identify trends and patterns in people's behavior before they've reached the final stage in their buyer's journey, meaning you can make more informed decisions about how to attract them to your website right at the top of the marketing funnel.
If you are wondering how to learn digital marketing step by step, search engine optimization (SEO) should actually be your first pit stop. SEO, in simple words, is the technique to get traffic from organic search results on search engines like Bing and Google. It aims to increase the quality and visibility of a website by having it ranked higher on the search engine results page. 

The mobile device is a uniquely personal medium that has transformed the customer journey. The pervasiveness and proximity of mobile makes it a powerful tool for marketers to understand and anticipate customer behavior. As a result, marketers now have the opportunity to respond to their users’ needs, goals, feelings, and expectations with a customized experience — both in and out of their mobile apps.

Search engines want to do their jobs as best as possible by referring users to websites and content that is most relevant to what the user is looking for. This is determined by the site content, how fast your site loads, how often your site is linked to from other credible online resources, and user experience, including design, navigation and bounce rate.
1. Let us consider that you want to establish a career in the Digital Marketing arena as a Digital Marketing Manager. In this case, learning Digital Marketing from experts should be your sole agenda. This is because as a digital marketing manager, you will have to deal with a number of responsibilities which will require you to have expertise in the subject. While self-study can help you gain knowledge, such expertise can only be inculcated if you learn from people who have the requisite experience.  
Customers are often researching online and then buying in stores and also browsing in stores and then searching for other options online. Online customer research into products is particularly popular for higher-priced items as well as consumable goods like groceries and makeup. Consumers are increasingly using the Internet to look up product information, compare prices, and search for deals and promotions.[23]
Those engaging with your company online via mobile devices need to have the same positive experience as they would on desktop. This means implementing a mobile-friendly or responsive website design to make browsing user-friendly for those on mobile devices. It might also mean reducing the length of your lead generation forms to create a hassle-free experience for people downloading your content on-the-go. As for your social media images, it's important to always have a mobile user in mind when creating them as image dimensions are smaller on mobile devices, meaning text can be cut-off.
It is important for a firm to reach out to consumers and create a two-way communication model, as digital marketing allows consumers to give back feed back to the firm on a community based site or straight directly to the firm via email.[26] Firms should seek this long term communication relationship by using multiple forms of channels and using promotional strategies related to their target consumer as well as word-of mouth marketing.[26]
Inbound marketing refers to a marketing methodology wherein you attract, engage, and delight customers at every stage of the buyer's journey. You can use every digital marketing tactic listed above, throughout an inbound marketing strategy, to create a customer experience that works with the customer, not against them. Here are some classic examples of inbound marketing versus traditional marketing: 
When starting out, focus on being a generalist. You won’t know what you’re most interested in yet, so building up a general digital marketing skill set will help you hone in on the areas that excite you most. You’ll also be more hireable since a digital marketer who can wear a few different hats is much more useful than one who only knows how to do Instagram ads.
