Today digital marketing has become a must-have for businesses that want to stay relevant and competitive in the digital marketplace. Digital marketing channels vary in the type of audience and the type of content they cater towards. From search engines, to social media, to web pages, and more – you can find parts of your customer base in any and all digital marketing channels, and get their attention using a variety of images, written copy, and videos. 
Now I am going to enlist some 7 types of Digital Marketing which include:
1. Search Engine Optimization (SEO): Search Engine Optimization or SEO refers to the process of growing your online visibility in non-paid (organic) search engine results. SERPs or search engine results pages appear to users after they search for a given set of keywords using a search engine like Google or Bing. Each user receives an individualized results page based on keywords, the user’s location at the time of searching, and their browsing history. The higher you rank on a SERP, the more traffic is directed to your site and the more chances of making a passive visitor an active customer.
2. Search Engine Marketing: Search Engine Marketing or SEM covers the ground SEO ignores, paid traffic from search engines. With SEM you purchase advertisement space that appears on a user’s SERP. For example Google AdWords and Bing Ads. The search engine charges a marketer a predetermined amount to display an advertisement in a number of places on a SERP generated from specific keywords or phrases. One example of SEM is pay-per-click advertising or PPC. It refers to a digital marketing method wherein search engines charge a company each time their advertisement is clicked. 
3. Social Media Marketing: It is a crucial part of your marketing strategy. Social media marketing gives you increased exposure. It allows you to connect with your consumers in a more intimate way. From this interaction, you can gain valuable customer feedback that allows you to improve your customer service, product, or service. Using social media marketing you’ll gain more reach when you post quality content. Everything you do to increase traffic or business on your social media channels is social media marketing. Whether you’re on Facebook, Twitter, Snapchat, or LinkedIn these efforts all amount to social media marketing.
4. Content Marketing: It efers to the practice of delivering a quality piece of content to your users to generate sales and leads. This content can live anywhere online. Tweets, a YouTube video, and blogs on your website all comprise content marketing. Content Marketing works because it melds together exceptional content with other types of digital marketing like SEO and Social Media Marketing. Content marketing is an ongoing practice. It’s not always about sales but more so about engaging and educating your consumer to build brand recognition, trust, and equity.
5. Affiliate Marketing: Affiliate marketing refers to the process of paying for conversions. Think of it like hiring a sales person for your product or service. That affiliate earns a commission. You determine the rate for affiliate marketing.  You only pay for conversions. This means there is no upfront cost to affiliate marketing. Many bloggers or e-commerce websites use affiliate marketing. 
6. Influencer Marketing: It is among the newer types of digital marketing. Influencer marketing uses people with an enormous online reach considered experts by your target market to drive traffic and sales. Influencer marketing is popular on social media channels like Instagram and Snapchat. Companies hire Instagrammers with large followings to promote their brand by posting one or more photos with the product. Always make sure to do your research on an influencer before you decide to do business with them. You might want to verify their Google analytics and make sure their following proves legitimate and not full of fake accounts.
7. Email Marketing: This type of marketing allows you to update your email subscribers on a regular basis about your company. This fosters a relationship unlike any of the other types of digital marketing. Your email updates provide value to your consumer. As a result, you build brand trust and brand loyalty. The best email marketing campaigns involve a list of subscribers earned by your content and company, not paid for by your company. People who opt-in to your email subscription prove more likely to become active buyers.
