SEM results show to a select target audience. SEO results do not. While successful SEO and SEM strategies are driven by a plan to connect with a select audience, you can only specify that target audience through SEM. Through SEM, you can (depending on the publisher) select what audiences you want to see the search results by assigning filters based on age, location, income, habits, and more. Through SEO, you cannot specifically choose who will see your search results.
When referring to the homepage, a trailing slash after the hostname is optional since it leads to the same content ("https://example.com/" is the same as "https://example.com"). For the path and filename, a trailing slash would be seen as a different URL (signaling either a file or a directory), for example, "https://example.com/fish" is not the same as "https://example.com/fish/". https://www.youtube.com/attribution_link?a=e29F5n3ea0I&u=watch?v=XXXXXX&feature=share
SEO is the foundation for good SEM and when you have each set up properly, you have a better chance of getting high-quality traffic and improving conversion rates. Once you have an SEO-friendly site and sponsored ads that are targeted properly using the right keywords, you have more chance of showing up at the top of paid searches. But you have to have your SEO in place in order for Google to see you as a credible website http://www.youtube.com/watch?v=7bNPg8UbhaE&feature=kp

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.
Search engine marketing, or SEM, is one of the most effective ways to grow your business in an increasingly competitive marketplace. With millions of businesses out there all vying for the same eyeballs, it’s never been more important to advertise online, and search engine marketing is the most effective way to promote your products and grow your business.
SEO should be a core tactic in any marketing strategy. While it might seem difficult to understand at first, as long as you find the right course, book or audiobook, and devote your time to learning, you'll be in good shape. Considering that there are over 200+ ranking factors in Google's current algorithms, learning, digesting and successfully implementing good SEO tactics is essential to the success of your website or blog. http://youtube.com/e/7bNPg8UbhaE
