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.

The better you learn and understand SEO and the more strides you take to learn this seemingly confusing and complex discipline, the more likely you'll be to appear organically in search results. And let's face it, organic search is important to marketing online. Considering that most people don't have massive advertising budgets and don't know the first thing about lead magnets, squeeze pages and sales funnels, appearing visible is critical towards long-term success.
A key objective is engaging digital marketing customers and allowing them to interact with the brand through servicing and delivery of digital media. Information is easy to access at a fast rate through the use of digital communications. Users with access to the Internet can use many digital mediums, such as Facebook, YouTube, Forums, and Email etc. Through Digital communications it creates a multi-communication channel where information can be quickly shared around the world by anyone without any regard to who they are. Social segregation plays no part through social mediums due to lack of face to face communication and information being wide spread instead to a selective audience. This interactive nature allows consumers create conversation in which the targeted audience is able to ask questions about the brand and get familiar with it which traditional forms of Marketing may not offer.
After your site has been built out, creating a social media presence is the best second step for most businesses. All businesses should have a Facebook Page that’s fully fleshed out with plenty of information about your business. Depending on your audience, you can also start a Twitter, Instagram, and/or Pinterest account. Social media is a long-term commitment that requires frequently updating and monitoring, but it’s one of the best ways to build an online community around your business.
Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
Organic posts, shared to your Facebook page without spend, are a nice way to engage with your audience as well. Share news and updates related to your business or share-worthy videos that engage, inspire, or entertain. When your followers share your videos, they help spread the word about your business to their friends and family, giving you more brand awareness.
SEO may generate an adequate return on investment. However, search engines are not paid for organic search traffic, their algorithms change, and there are no guarantees of continued referrals. Due to this lack of guarantees and certainty, a business that relies heavily on search engine traffic can suffer major losses if the search engines stop sending visitors. Search engines can change their algorithms, impacting a website's placement, possibly resulting in a serious loss of traffic. According to Google's CEO, Eric Schmidt, in 2010, Google made over 500 algorithm changes – almost 1.5 per day. It is considered a wise business practice for website operators to liberate themselves from dependence on search engine traffic. In addition to accessibility in terms of web crawlers (addressed above), user web accessibility has become increasingly important for SEO.
