Web designers are code-writers and graphics experts that are responsible for developing and implementing the online image of the product. This role involves creating not only the look of websites and applications, but engineering the user experience. A web designer should always pay attention to how easy the materials are to read and use, ensuring smooth interactions for the customer and making sure the form of the materials serve the function of the campaign.
Getting unique and authoritative links is crucial for higher ranking in the SERPs and improving your SEO. Google's algorithm on evaluation of links evolved in recent years creating a more challenging process now to get high quality backlinks. External links still matter and aren’t obsolete, so start working on strategies to get valuable backlinks to improve your search visibility.
While ordinary users were not that interested in pages' scores, SEOs of a different caliber felt that this was a great opportunity to make a difference for their customers. This obsession of SEOs with PageRank made everyone feel that this ranking signal is more or less the only important one. In spite of the fact that pages with a lower PR score can beat those with a higher score! What did we receive then, as a result?

At the time I was strongly advocating page rank sculting by inclusion of no follow links on “related product” links. It’s interesting to note that my proposed technique would have perhaps worked for a little while then would have lost its effectiveness. Eventualy I reached the point where my efforts delivered diminishing returns which was perhaps unavoidable.
One of the earliest adopters of Internet marketing in the world of Fortune 500 companies was the Coca-Cola Corporation. Today, this huge purveyor of soft drinks has one of the strongest online portfolios in the world. More than 12,000 websites link to the Coca-Cola homepage, which itself is a stunning display of Internet savvy. Their homepage alone sports an auto-updating social network column, an embedded video, a unique piece of advertising art, frequently rotating copy, an opt-in user registration tab, tie-in branding with pop culture properties, and even a link to the company's career opportunities page. Despite how busy that sounds, the Coca-Cola homepage is clean and easy to read. It is a triumph of Internet marketing for its confidence, personality, and professionalism.
PageRank is a link analysis algorithm and it assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is referred to as the PageRank of E and denoted by {\displaystyle PR(E).} Other factors like Author Rank can contribute to the importance of an entity.
Totally agree — more does not always equal better. Google takes a sort of ‘Birds of a Feather’ approach when analyzing inbound links, so it’s really all about associating yourself (via inbound links) with websites Google deems high quality and trustworthy so that Google deems YOUR web page high quality and trustworthy. As you mentioned, trying to cut corners, buy links, do one-for-one trades, or otherwise game/manipulate the system never works. The algorithm is too smart.
Thanks for sharing this, Matt. I’m happy that you took the time to do so considering that you don’t have to. What I mean is, in an ideal world, there should be no such thing as SEO. It is the SE’s job to bring the right users to the right sites and it is the job of webmasters to cater to the needs of the users brought into their sites by SEs. Webmasters should not be concerned of bringing the users in themselves. (aside from offsite or sponsored marketing campaigns) The moment they do, things start to get ugly because SEs would now have to implement counter-measures. (To most SEO tactics) This becomes an unending spiral. If people only stick to their part of the equation, SEs will have more time to develop algorithms for making sure webmasters get relevant users rather than to develop algorithms for combating SEOs to ensure search users get relevant results. Just do your best in providing valuable content and Google will try their best in matching you with your users. Don’t waste time trying to second guess how Google does it so that you can present yourself to Google as having a better value than you really have. They have great engineers and they have the code—you only have a guess. At most, the SEO anyone should be doing is to follow the webmasters guidelines. It will benefit all.
I am not worried by this; I do agree with Danny Sullivan (Great comment Danny, best comment I have read in a long time). I will not be changing much on my site re: linking but it is interesting too see that Google took over a year to tell us regarding the change, but was really happy to tell us about rel=”nofollow” in the first place and advised us all to use it.

where N is the total number of all pages on the web. The second version of the algorithm, indeed, does not differ fundamentally from the first one. Regarding the Random Surfer Model, the second version's PageRank of a page is the actual probability for a surfer reaching that page after clicking on many links. The PageRanks then form a probability distribution over web pages, so the sum of all pages' PageRanks will be one.
Matt, I’ve been a firm believer of the thought that webmasters shouldn’t really bother too much about the calculations that Google would do while spotting external links on a site. Leave that to Google. You write the content and if you find relevant resources, link to it. Why worry over PR ? In case you’re so sure about the linked site to be “kinda spammy” then nofollow it. That’s it.

PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. In fact the name. PageRank is a likely play on Larry Page's name. At the time that Page and Brin met, early search engines typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to attract higher search page results. Sometimes web designers would even put hidden text on pages to repeat phrases.
