The answer, at its basis, is largely what I convey in a great majority of my books about search engine optimization and online marketing. It all boils down to one simple concept: add tremendous amounts of value to the world. The more value you add, the more successful you become. Essentially, you have to do the most amount of work (initially at least) for the least return. Not the other way around.
Let’s start with what Google says. In a nutshell, it considers links to be like votes. In addition, it considers that some votes are more important than others. PageRank is Google’s system of counting link votes and determining which pages are most important based on them. These scores are then used along with many other things to determine if a page will rank well in a search.
While SEOs can provide clients with valuable services, some unethical SEOs have given the industry a black eye by using overly aggressive marketing efforts and attempting to manipulate search engine results in unfair ways. Practices that violate our guidelines may result in a negative adjustment of your site's presence in Google, or even the removal of your site from our index.
Once the company has identified the target demographic for its Internet marketing campaign, they then decide what online platforms will comprise the campaign. For instance, a company that is seeking customers from the 18 to 33 demographic should develop a mobile application that raises awareness about the product, such as a game, a news feed, or a daily coupon program users can download for free.
Search engine optimization (SEO) is the process of improving the visibility of a website or webpage on a search engine results page (SERP) so as to make a company’s website more discoverable (i.e., on the first page/s), thereby driving traffic and sales. Tedious, involving technical and business decisions, and not guaranteeing results—it nonetheless provides lasting benefits.
As an example, people could previously create many message-board posts with links to their website to artificially inflate their PageRank. With the nofollow value, message-board administrators can modify their code to automatically insert "rel='nofollow'" to all hyperlinks in posts, thus preventing PageRank from being affected by those particular posts. This method of avoidance, however, also has various drawbacks, such as reducing the link value of legitimate comments. (See: Spam in blogs#nofollow)
Search engine optimization is a key part of online marketing because search is one of the primary ways that users navigate the web. In 2014, over 2.5 trillion searches were conducted worldwide across search engines such as Google, Bing, Yahoo, Baidu, and Yandex. For most websites, traffic that comes from search engines (known as "natural" or "organic" traffic) accounts for a large portion of their total traffic.
