I think Google will always be working to discern and deliver “quality, trustworthy” content and I think analyzing inbound links as endorsements is a solid tool the SE won’t be sunsetting anytime soon. Why would they? If the president of the United States links to your page that is undoubtedly an endorsement that tells Google you’re a legitimate trusted source. I know that is an extreme example, but I think it illustrates the principals of a linking-as-endorsement model well.
A PageRank results from a mathematical algorithm based on the webgraph, created by all World Wide Web pages as nodes and hyperlinks as edges, taking into consideration authority hubs such as cnn.com or usa.gov. The rank value indicates an importance of a particular page. A hyperlink to a page counts as a vote of support. The PageRank of a page is defined recursively and depends on the number and PageRank metric of all pages that link to it ("incoming links"). A page that is linked to by many pages with high PageRank receives a high rank itself.
Disney initially stated they wouldn’t exceed one million in donations, but ended up donating two million after the campaign blew up. #ShareYourEars campaign garnered 420 million social media impressions, and increased Make-A-Wish’s social media reach by 330%. The campaign is a powerful example of using an internet marketing strategy for a good cause. #ShareYourEars raised brand awareness, cultivated a connected online community, and positively affected Disney’s brand image.
“So what happens when you have a page with “ten PageRank points” and ten outgoing links, and five of those links are nofollowed? Let’s leave aside the decay factor to focus on the core part of the question. Originally, the five links without nofollow would have flowed two points of PageRank each (in essence, the nofollowed links didn’t count toward the denominator when dividing PageRank by the outdegree of the page). More than a year ago, Google changed how the PageRank flows so that the five links without nofollow would flow one point of PageRank each.”
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking. Another category sometimes used is grey hat SEO. This is in between black hat and white hat approaches, where the methods employed avoid the site being penalized, but do not act in producing the best content for users. Grey hat SEO is entirely focused on improving search engine rankings.
Just as some backlinks you earn are more valuable than others, links you create to other sites also differ in value. When linking out to an external site, the choices you make regarding the page from which you link (its page authority, content, search engine accessibility, and so on) the anchor text you use, whether you choose to follow or nofollow the link, and any other meta tags associated with the linking page can have a heavy impact on the value you confer.
Make it as easy as possible for users to go from general content to the more specific content they want on your site. Add navigation pages when it makes sense and effectively work these into your internal link structure. Make sure all of the pages on your site are reachable through links, and that they don't require an internal "search" functionality to be found. Link to related pages, where appropriate, to allow users to discover similar content. Denver Page Rank Click Here
