6. Measurement and analysis. You won’t get far in SEO unless you know how to measure your results, interpret those results, and use your analysis to make meaningful changes to your approach. The best tool for the job is still Google Analytics, especially if you’re new to the game. Spend some time experimenting with different metrics and reports, and read up on Analytics knowledge base articles. There’s a deep world to dive into. http://www.youtube.com/watch?feature=youtube_gdata&v=7bNPg8UbhaE
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[39] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[40] in addition to their URL submission console.[41] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[42] however, this practice was discontinued in 2009.
Anyone looking towards a career in digital marketing should have a good grasp not only on how SEO and SEM function in today’s current digital atmosphere, but they should be looking to how both will change as we become more and more reliant on technology. Having a solid grasp of how each of these are involved in digital marketing campaigns will be especially crucial in the digital marketplace in the coming years. 
7. Keyword research. Specific target keywords aren’t as important for SEO success as they used to be, now that Google search is fueled by semantic and contextual understanding, but you should still be able to identify both head keyword (short, high-volume keywords) and long-tail keyword (longer, conversational, low-volume keywords) targets to guide the direction of your campaign. http://m.youtu.be/7bNPg8UbhaE
