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.[22] 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.

Search engines find and catalog web pages through spidering (also known as webcrawling) software. Spidering software "crawls" through the internet and grabs information from websites which is used to build search engine indexes. Unfortunately, not all search engine spidering software works the same way, so what gives a page a high ranking on one search engine may not necessarily give it a high ranking on another. Note that rather than waiting for a search engine to discover a newly created page, web designers can submit the page directly to search engines for cataloging.
Excellent post Brian. I think the point about writing content that appeals to influencers in spot on. Could you recommend some good, manual strategies through which I can spot influencers in boring niches *B2B* where influencers are not really talking much online? Is it a good idea to rely on newspaper articles to a feel for what a particular industry is talking about? Would love to hear your thoughts on that.
This post and the Skycraper technique changed my mind about how I approach SEO, I’m not a marketing expert and I haven’t ranked sites that monetize really well, I’m just a guy trying to get some projects moving on and I’m not even in the marketing business so I just wanted to say that the way you write makes the information accesible, even if you’re not a native english speaker as myself.
Hi Brian, i absolutely love your content.My competitors and influence rs are very strong-most of them government bodies or supported by government, or travel guides known worldwide.I constantly follow them,get onto them.like,share,comment etc.they share photos that are submitted to them,and i do photography myself which takes hours and still can’t reach out big audience…Any idea please what could i create that my influence rs would love to share (hard to find out what they care,they get 100’s photos submitted daily and collaborate with other big names…) Please help me.
Website owners recognized the value of a high ranking and visibility in search engine results,[6] 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.[7] On May 2, 2007,[8] Jason Gambert attempted to trademark the term SEO by convincing the Trademark Office in Arizona[9] that SEO is a "process" involving manipulation of keywords and not a "marketing service."
