SEM is the wider discipline that incorporates SEO. SEM includes both paid search results (using tools like Google Adwords or Bing Ads, formerly known as Microsoft adCenter) and organic search results (SEO). SEM uses paid advertising with AdWords or Bing Ads, pay per click (particularly beneficial for local providers as it enables potential consumers to contact a company directly with one click), article submissions, advertising and making sure SEO has been done. A keyword analysis is performed for both SEO and SEM, but not necessarily at the same time. SEM and SEO both need to be monitored and updated frequently to reflect evolving best practices.

With 360° videos, viewers “scroll” around to see content from every angle — as if they were physically standing within the content. This spherical video style allows viewers to experience a location or event, such as exploring Antarctica or meeting a hammerhead shark. Virtual reality (VR) allows viewers to navigate and control their experience. These videos are usually viewed through devices such as Oculus Rift or Google Cardboard. Internet Marketing Services
In some contexts, the term SEM is used exclusively to mean pay per click advertising, particularly in the commercial advertising and marketing communities which have a vested interest in this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as search engine optimization and search retargeting.
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow. Internet Marketing Services
SEO is the process of increasing organic traffic by creating content and optimizing webpages that match what search engine users are seeking. Search engine algorithms are closer than ever to mimicking a human understanding of query intent based on artificial intelligence; therefore the focus of all aspects of SEO need to be biased toward users with an emphasis on relevancy, quality, and engagement.
