PageRank: a True CommodityWhat is PageRank Worth? Whatever people are willing to pay for it. Nothing more, nothing less... How does PageRank Relate to Relevancy or Rankings? Some people believe that PageRank directly relates to relevancy, but it doesn't. In the past the Google algorithm was more reliant upon PageRank than it is today, but currently PageRank is a small factor in the Google search algorithm. Currently the biggest factor in Google's search relevancy is getting many keyword rich links from a large variety of C block IP addresses. Getting a bunch of links from a single source is easy. Getting links from many different sources is much more time consuming and expensive. Why do People Make Such a BIG Deal out of PageRank? When your site is new you will have a PageRank of 0. After you get a few links in about a month or two you will see your PageRank go up and it is usually one of your first signs of SEO progress. People see that and as they continue to work they associate their improved rankings with the improved PageRank. Since PageRank is one of only a few visual signs of SEO progress (the others being inbound links and actual rankings) and it is often easier to get a mid ranged PageRank than it is to get strong rankings many people place too much focus on PageRank. Additionally many link brokers and sites selling links use PageRank as a factor to determine the price at which they sell text links. How Search Engines Work Search engines try to place the most relevant results at the top. These results are not necessarily the most optimized pages with the most links. In fact the whole reason pages and sites are optimized is to deceive search engines into thinking the sites and pages are of greater quality and value than they actually are. As webmasters learn more about search algorithms the algorithms are required to evolve. As you and I learn more about how Google works the relevancy of their search results decline. Google likes the fact that many people focus on PageRank because in doing so people are missing the bigger picture: PageRank is not that important anymore. Why PageRank is Not Important Tons of people know about PageRank because it is an extremely simple concept to understand. Google is not going to go public as a company worth billions of dollars because they rely heavily upon a system that is easy for anyone to manipulate. What makes a search engine valuable is not what you know and can manipulate, but the things you do not know about. New filters, clustering technologies, semantic grading of pages, and the fact that Google can change to heavily integrate any of these new technologies into their algorithm at any time is what keeps webmasters on their toes. The knowledge to be able to continually make better technologies work is what makes Google valuable. How Easy is it to Manipulate PageRank? Super easy. Lets say I have a PR6 website. If I decide to create another site and link to it from all the pages on my current website then my new site would automatically get at least a PR5. Most industries only have a PR5 or PR6 site as the top ranking result. If PageRank were the primary driving factor behind the Google search algorithm I could dominate a new industry every month without investing much money. Google doesn't want that. Pockets of PageRank PageRank is worth whatever people are willing to pay for it. While most of the value of PageRank is artificial based upon aggressive business models with high profit margins at some spots you can still buy PageRank for well under fair market value. I like to call these spots "pockets of PageRank." Pockets of PageRank exist on the web from small scale to large scale sites. One great large scale example is the Internet.com network. You can buy keyword rich text links throughout their network of sites for $7,500 a month. Most sites that are doing this likely will get a PR of 7 or 8 right out the gate. If you think beyond your own business model and think about all the various different commercial interests on the web there are a ton of websites that could easily afford to spend $10,000 a month renting links. Many major link brokers also list some of their own topical directories on some of their more powerful sites that they are brokering links from. The same way I can use my sites to make anything get a PR5 or PR6 right out of the gate many link brokers make topical directories with a PR6 or PR7 based on giving them one or two exceptionally strong inbound links from a site they manage. They in turn can provide these listings free for those who reciprocate links back to the directory or to their clients sites and also as bonus kicker links to their customers. 上一篇：怎么样正确选择关键字 下一篇：提高网站在Google中的排名——面向搜索引擎的网站设计 更多相关文章
