In 1998, two graduate students at Stanford University, Larry Page and Sergey Brin, developed "Backrub", a search engine that relied on a mathematical algorithm to rate the prominence of web pages. The number calculated by the algorithm, PageRank, is a function of the quantity and strength of inbound links.[21] PageRank estimates the likelihood that a given page will be reached by a web user who randomly surfs the web, and follows links from one page to another. In effect, this means that some links are stronger than others, as a higher PageRank page is more likely to be reached by the random web surfer.

In 2014, Cisco stated that video made 64% of all internet traffic. In 2015, Searchmetrics was releasing a white paper quoting that 55% of all keyword searches in the U.S. return at least one video blended into Google’s web search results and that 8 out 10 of those videos belonged to YouTube. And in 2016, Cisco was also sharing that online videos will account for more than 80% of all consumer internet traffic by 2020.

Chrys was bitten by the entrepreneurial bug at an early age. At age 10, she bought soccer cards in bulk and sold them in school. Later, she turned down a university scholarship and moved to Thailand to start an apparel business. By age 27, she started and ran two online businesses while living around the world. She now runs Chrys Media, an educational company that runs online conferences, courses, and workshops for entrepreneurs and marketers.
Billions of people search the web every day. Search engine marketing (SEM for short) is how you can get your ads in front of these future customers where it counts: in premium spots on the first page of search results. You set your own budget and are charged only when your ad is clicked. This makes SEM an affordable way to reach more customers for businesses of all sizes — including yours.
Make sure you have some good analytics software installed on your website. You will want to know where your traffic is coming from. Is it coming from social media, referrals, search engine queries, or is it direct traffic? It will also help you determine where people are getting lost, or dropping out of the funnel. It can also help you determine what approaches, content, and CTAs are the most effective.
On April 24, 2012 many started to see that Google has started to penalize companies that are buying links for the purpose of passing off the rank. The Google Update was called Penguin. Since then, there have been several different Penguin/Panda updates rolled out by Google. SEM has, however, nothing to do with link buying and focuses on organic SEO and PPC management. As of October 20, 2014 Google has released three official revisions of their Penguin Update.

Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
