Start Value (In this case) is the number of actual links to each “node”. Most people actually set this to 1 to start, but there are two great reasons for using link counts. First, it is a better approximation to start with than giving everything the same value, so the algorithm stabilizes in less iterations and it is so useful to check my spreadsheet in a second… so node A has one link in (from page C)
Also hadn’t thought about decreasing the rank value based on the spammyness of sites a page is linking into. My guess on how to do it would be determining the spammyness of individual pages based on multiple page and site factors, then some type of reverse pagerank calcuation starting with the those bad scores, then overlaying that on top of the “good” pagerank calculation as a penalty. This is another thing which would be interesting to play around with in the Nutch algorithm.
Unfortunately, SEO is also a slow process. You can make “quick wins” in markets which are ill-established using SEO, but the truth is that the vast majority of useful keyphrases (including long-tail keyphrases) in competitive markets will already have been optimized for. It is likely to take a significant amount of time to get to a useful place in search results for these phrases. In some cases, it may take months or even years of concentrated effort to win the battle for highly competitive keyphrases.
I liken this to a paradoxical Catch-22 scenario, because it seems like without one you can't have the other. It takes money to drive traffic, but it takes traffic to make money. So don't make the mistake that millions of other online marketers make around the world. Before you attempt to scale or send any semblance of traffic to your offers, be sure to split-test things to oblivion and determine your conversion rates before diving in headfirst.
For most parts the sophistication in this system is simplified here. I still have trouble understanding the difference between letting link flow withing my pages without thinking about a loop. For example, page A, B and C link to each other from all angles therefore the link points should be shared. But in this loop formula, page B does not link to A. It just goes to C and loops. How does this affect navigation bars? As you know they are meant to link stay on top and link to all pages. I’m lost.
7. Keyword research. Specific target keywords aren’t as important for SEO success as they used to be, now that Google search is fueled by semantic and contextual understanding, but you should still be able to identify both head keyword (short, high-volume keywords) and long-tail keyword (longer, conversational, low-volume keywords) targets to guide the direction of your campaign.
Could the nofollow change could be interpreted as a form of usability guidance? For instance, I’ve recently removed drop-down menus from a handful of sites because of internal link and keyword density issues. This wasn’t done randomly. Tests were done to measure usage and value of this form of navigation that made it easy to make the change – allowing usability and SEO to dovetail nicely.

What's the authority of your website or webpage, or any other page on the internet for that matter where you're attempting to gain visibility? Authority is an important component of trust, and it relies heavily on quality links coming from websites that Google already trusts. Authority largely relates to the off-page optimization discipline of SEO that occurs away from the webpage as opposed to the on-page optimization that occurs directly on the webpage.

I was exactly thinking the same thing what Danny Sullivan had said. If comments (even with nofollow) directly affect the outgoing PR distribution, people will tend to allow less comments (maybe usage of iframes even). Is he right? Maybe, Google should develop a new tag as well something like rel=”commented” to inform spiders about it to give less value and wordpress should be installed default with this attribute 🙂
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.
All sites have a home or "root" page, which is usually the most frequented page on the site and the starting place of navigation for many visitors. Unless your site has only a handful of pages, you should think about how visitors will go from a general page (your root page) to a page containing more specific content. Do you have enough pages around a specific topic area that it would make sense to create a page describing these related pages (for example, root page -> related topic listing -> specific topic)? Do you have hundreds of different products that need to be classified under multiple category and subcategory pages?
Most online marketers mistakenly attribute 100% of a sale or lead to the Last Clicked source. The main reason for this is that analytic solutions only provide last click analysis. 93% to 95% of marketing touch points are ignored when you only attribute success to the last click. That is why multi-attribution is required to properly source sales or leads.
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)
I think that removing the link to the sitemap shouldn’t be a big problem for the navigation, but I wonder what happens with the disclaimer and the contact page? If nofollow doesn’t sink the linked page, how can we tell the search engine that these are not content pages. For some websites these are some of the most linked pages. And yes for some the contact page is worth gaining rank, but for my website is not.
