Each type of algorithm definitely looks at different aspects of the webpage, such as Meta tags, title tags, links, keyword density, etc., yet they all are part of a much larger algorithm. That is the reason why same search string generates different results in different search engines having distinct algorithms. And all these search engines (primary, secondary, and targeted) periodically do keep on changing their algorithms, so you must know how to adapt to these changes if you want to stay on the top. This requires sound SEO expertise.
Digital marketing does not work in a silo. It operates in an environment wherein a variety of specific components function in an interconnected and interdependent way. Be it data mining, link building, customer resource management, or landing page conversion, every aspect of these domains speaks volumes about the strength of digital marketing as a career.
Social media has a pivotal role – Last but not least, social media is an evolving platform that has changed from a basic communication platform to a highly profitable marketing channel. Many users start their searches on social media and make their way to a business’s site. Sharing up-to-date, engaging, and personalized content will attract more people to your profile, and eventually to your website.
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.
Once you’ve found your sandbox, you can narrow down the stack you want to apply to it. As I mentioned in my Wiki Strategy article, it helps to be very focused in your growth channels, so if you said “social media” before, try picking just one social media channel to put most of your focus on. For ads, pick one platform (Facebook or Google) and focus on that. You can always expand your channels later, but if you try to do everything at once in the beginning, you’ll burn yourself out.
