SEO is also about making your search engine result relevant to the user's search query so more people click the result when it is shown in search. In this process, snippets of text and meta data are optimized to ensure your snippet of information is appealing in the context of the search query to obtain a high CTR (click through rate) from search results.
With the advent of portable devices, smartphones, and wearable devices, watches and various sensors, these provide ever more contextual dimensions for consumer and advertiser to refine and maximize relevancy using such additional factors that may be gleaned like: a person's relative health, wealth, and various other status, time of day, personal habits, mobility, location, weather, and nearby services and opportunities, whether urban or suburban, like events, food, recreation, and business. Social context and crowd sourcing influences can also be pertinent factors.
An authority website is a site that is trusted by its users, the industry it operates in, other websites and search engines. Traditionally a link from an authority website is very valuable, as it’s seen as a vote of confidence. The more of these you have, and the higher quality content you produce, the more likely your own site will become an authority too.
In an effort to manually control the flow of PageRank among pages within a website, many webmasters practice what is known as PageRank Sculpting—which is the act of strategically placing the nofollow attribute on certain internal links of a website in order to funnel PageRank towards those pages the webmaster deemed most important. This tactic has been used since the inception of the nofollow attribute, but may no longer be effective since Google announced that blocking PageRank transfer with nofollow does not redirect that PageRank to other links.

Optimizing digital marketing can be tricky, and a simple definition does not necessarily translate into something that is useful for achieving business objectives. That is where the RACE Digital Marketing Planning framework comes in, as it can help break down digital marketing into easier to manage areas that can then be planned, managed and optimized.
Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. If web surfers who start on a random page have an 85% likelihood of choosing a random link from the page they are currently visiting, and a 15% likelihood of jumping to a page chosen at random from the entire web, they will reach Page E 8.1% of the time. (The 15% likelihood of jumping to an arbitrary page corresponds to a damping factor of 85%.) Without damping, all web surfers would eventually end up on Pages A, B, or C, and all other pages would have PageRank zero. In the presence of damping, Page A effectively links to all pages in the web, even though it has no outgoing links of its own.
More specifically, who gets to appear on the page and where is based on an advertiser’s Ad Rank, a metric calculated by multiplying two key factors – CPC Bid (the highest amount an advertiser is willing to spend) and Quality Score (a value that takes into account your click-through rate, relevance, and landing page quality, among other factors). In turn, your Quality Score affects your actual cost per click, or CPC.
Website owners recognized the value of a high ranking and visibility in search engine results, creating an opportunity for both white hat and black hat SEO practitioners. According to industry analyst Danny Sullivan, the phrase "search engine optimization" probably came into use in 1997. Sullivan credits Bruce Clay as one of the first people to popularize the term. On May 2, 2007, Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona that SEO is a "process" involving manipulation of keywords and not a "marketing service."
