In early 2005, Google implemented a new value, "nofollow",[64] for the rel attribute of HTML link and anchor elements, so that website developers and bloggers can make links that Google will not consider for the purposes of PageRank—they are links that no longer constitute a "vote" in the PageRank system. The nofollow relationship was added in an attempt to help combat spamdexing.

My favorite style in this is article marketing. You create anchor content on your website or blog, then you build authority-content links to that content, effectively driving up the visibility. I've used this single strategy to rank hundreds of keywords in the #1 spot on Google, and I would highly recommend that if you're going to learn any marketing strategy, that you get really good at this one.
Internet marketing is not a singular approach to raising interest and awareness in a product. Because of the vast number of platforms the Internet creates, the field encompasses several disciplines. It involves everything from email, to Search Engine Optimization (SEO), to website design, and much more to reach an ever-evolving, ever-growing audience. (See also Web Marketing)

With focus I mean making sure that your pages focus on the same keyword everywhere, and your site focuses on the same high level keywords and sections in your site focusing on their own high level (but not as high as the keywords for which you want your home page to rank) keywords. Focus few people really understand while the interesting thing is that you do this almost automatically right if you do your site architecture and understanding your customers, right.
Backlink is a link one website gets from another website. Backlinks make a huge impact on a website’s prominence in search engine results. This is why they are considered very useful for improving a website’s SEO ranking. Search engines calculate rankings using multiple factors to display search results. No one knows for sure how much weight search engines give to backlinks when listing results, however what we do know for certain is that they are very important.
In an effort to manually control the flow of PageRank among pages within a website, many webmasters practice what is known as PageRank Sculpting[65]—which is the act of strategically placing the nofollow attribute on certain internal links of a website in order to funnel PageRank towards those pages the webmaster deemed most important. This tactic has been used since the inception of the nofollow attribute, but may no longer be effective since Google announced that blocking PageRank transfer with nofollow does not redirect that PageRank to other links.[66]
In my view, the Reasonable Surfer model would findamentally change the matrix values above, so that the same overall PageRank is apportioned out of each node, but each outbound link carres a different value. In this scenario, you can indeed make the case that three links will generate more traffic than one, although the placement of these links might increase OR DECREASE the amount of PageRank that is passed, since (ultimately) the outbound links from page A to Page B are dependent on the location of all other outbound links on Page A. But this is the subject of another presentation for the future I think.
The nofollow tag is being used for page rank sculpting and to stop blog spamming. In my mind this is tant amount to manipulating page rank and thus possibly ranking position in certain cases. I do post to regularly blogs and forums regarding web design and this improved my search ranking as a side effect. Whats wrong with making an active contribution to the industry blogs and being passed some Pagerank. Google needs to determine whether the post entry is relevant then decide to pass pagerank after the analysis or just decide that blog should not pass PR in any event. Whats gone wrong with the Internet when legitimate content pages do not pass PR?
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images. 

Webmasters and content providers began optimizing websites for search engines in the mid-1990s, as the first search engines were cataloging the early Web. Initially, all webmasters needed only to submit the address of a page, or URL, to the various engines which would send a "spider" to "crawl" that page, extract links to other pages from it, and return information found on the page to be indexed.[5] The process involves a search engine spider downloading a page and storing it on the search engine's own server. A second program, known as an indexer, extracts information about the page, such as the words it contains, where they are located, and any weight for specific words, as well as all links the page contains. All of this information is then placed into a scheduler for crawling at a later date.
But this leads to a question — if my husband wants to do a roundup of every Wagner Ring Cycle on DVD, that’s about 8 Amazon links on the page, all bleeding PR away from his substantive insights. If he, instead, wants to do a roundup of every Ring Cycle on CD, that’s about two dozen items worth discussing. The page would be very handy for users, and would involve considerably more effort on his part… but no good deed goes unpunished, and in the eyes of Google the page would be devalued by more than two thirds.

And my vital question about Amazon affiliate links. I think many people also wonder about it as well. I have several blogs where I solely write unique content reviews about several Amazon products, nothing more. As you know, all these links are full of tags, affiliate IDs whatsoever (bad in SEO terms). Should I nofollow them all or leave as they are?


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.
Something a lot of people seem to have overlooked was hinted at in Greg Boser’s comment above. Greg identified that there is a major (and unfair) disparity with how authority sites such as Wikipedia disrupt the linkscape by run-of-site nofollows. Once Wikipedia implemented the no-follows, previously high-value links from Wikipedia were rendered worthless making the site less of a target for spammers. Increasingly large sites are following suit in order to cleanse their own pages of spam.

Of course, important pages mean nothing to you if they don’t match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all dozens of aspects of the page’s content (and the content of the pages linking to it) to determine if it’s a good match for your query.
A breadcrumb is a row of internal links at the top or bottom of the page that allows visitors to quickly navigate back to a previous section or the root page. Many breadcrumbs have the most general page (usually the root page) as the first, leftmost link and list the more specific sections out to the right. We recommend using breadcrumb structured data markup28 when showing breadcrumbs.
