The priority given to the placement of a link on the results page of a Web search. For example, Google's PageRank system, named after co-founder Larry Page, classifies a site based on the number of links that point to it from other sites (the "backlinks"). The concept is that if very prominent sites link to a site, the site has greater value. The more popular the backlink sites themselves are, the higher the ranking as well.
Here’s how it works: Every time your ad is clicked, sending a visitor to your website, you pay the search engine a small fee. (That’s why it’s called “pay per click.”) When your PPC campaign is well-designed and running smoothly, that fee will be trivial, because the visit is worth more to your business than what you pay for it. For example, if you pay $10 for a click, but the click results in a $300 sale, then using PPC is a no-brainer.
In the parlance of digital marketing, advertisers are commonly referred to as sources, while members of the targeted ads are commonly called receivers. Sources frequently target highly specific, well-defined receivers. For example, after extending the late-night hours of many of its locations, McDonald's needed to get the word out. It targeted shift workers and travelers with digital ads, because the company knew that these people made up a large segment of its late night business. McDonald's encouraged them to download a new Restaurant Finder app, targeting them with ads placed at ATMs and gas stations, as well as on websites that it new its customers frequented at night.
All major crawler-based search engines leverage links from across of the web, but none of them report a static “importance” score in the way Google does via its Google Toolbar. That score, while a great resource for surfers, has also provided one of the few windows into how Google ranks web pages. Some webmasters, desperate to get inside Google, keep flying into that window like confused birds, smacking their heads and losing their orientation….
As an Internet marketing strategy, SEO considers how search engines work, the computer programmed algorithms which dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, adding content, doing HTML, and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic. By May 2015, mobile search had surpassed desktop search.[3] In 2015, it was reported that Google is developing and promoting mobile search as a key feature within future products. In response, many brands are beginning to take a different approach to their Internet marketing strategies.[4]
