i.e. the PageRank value for a page u is dependent on the PageRank values for each page v contained in the set Bu (the set containing all pages linking to page u), divided by the number L(v) of links from page v. The algorithm involves a damping factor for the calculation of the pagerank. It is like the income tax which the govt extracts from one despite paying him itself.

## The eigenvalue problem was suggested in 1976 by Gabriel Pinski and Francis Narin, who worked on scientometrics ranking scientific journals,[8] in 1977 by Thomas Saaty in his concept of Analytic Hierarchy Process which weighted alternative choices,[9] and in 1995 by Bradley Love and Steven Sloman as a cognitive model for concepts, the centrality algorithm.[10][11]

Before online marketing channels emerged, the cost to market products or services was often prohibitively expensive, and traditionally difficult to measure. Think of national television ad campaigns, which are measured through consumer focus groups to determine levels of brand awareness. These methods are also not well-suited to controlled experimentation. Today, anyone with an online business (as well as most offline businesses) can participate in online marketing by creating a website and building customer acquisition campaigns at little to no cost. Those marketing products and services also have the ability to experiment with optimization to fine-tune their campaigns’ efficiency and ROI.
###### 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.

Changes to the algorithms that produce search engine rankings can place a heightened focus on relevance to a particular topic. While some backlinks might be from sources containing highly valuable metrics, they could also be unrelated to the consumer's query or interest. An example of this would be a link from a popular shoe blog (with valuable metrics) to a site selling vintage pencil sharpeners. While the link appears valuable, it provides little to the consumer in terms of relevance.
Thanks for the article (and lead-off links as they were good info too) but I did not quite get – if there was a penalisation by Google for sculpting – from the article or whether it was just bad practice? And also to echo what someone else asked ‘is it WORTH actually undoing this type of work on websites SEO’s have worked on’ or simply change the way we work with new sites?
Using influencers to market your products or services is a great way to quickly saturate yourself into the marketplace, no matter what you're peddling. However, finding the right influencer at the right price is the hard part. You don't necessarily have to go to the top-tier influencers; you can also opt for micro-influencers (those that have 10,000 to 100,000 followers or fans).
```Halfdeck; Don’t you think the big problem is that Google is giving too much information to the industry? I stated a long time ago this fact, wondering why they wish to constantly hand out more information when they should have known the industry would try their best to exploit anyway. Not only that, but wanting more and more no matter how much Google hands out is something that is very clear as well. You just stated you want “more detail”. Why? I’m thinking too much detail handed out over the years is Google’s biggest problem right now. Considering the total majority of websites on the internet don’t know what a nofollow attribute is anyway, what exactly is Google gaining by giving up parts of their algo to the SEO industry? Big mistake. They should actually just shut up.

# He is the co-founder of Neil Patel Digital. The Wall Street Journal calls him a top influencer on the web, Forbes says he is one of the top 10 marketers, and Entrepreneur Magazine says he created one of the 100 most brilliant companies. Neil is a New York Times bestselling author and was recognized as a top 100 entrepreneur under the age of 30 by President Obama and a top 100 entrepreneur under the age of 35 by the United Nations.

Suppose instead that page B had a link to pages C and A, page C had a link to page A, and page D had links to all three pages. Thus, upon the first iteration, page B would transfer half of its existing value, or 0.125, to page A and the other half, or 0.125, to page C. Page C would transfer all of its existing value, 0.25, to the only page it links to, A. Since D had three outbound links, it would transfer one third of its existing value, or approximately 0.083, to A. At the completion of this iteration, page A will have a PageRank of approximately 0.458.
Since heading tags typically make text contained in them larger than normal text on the page, this is a visual cue to users that this text is important and could help them understand something about the type of content underneath the heading text. Multiple heading sizes used in order create a hierarchical structure for your content, making it easier for users to navigate through your document.
If you decide to go into affiliate marketing, understand that you will need a lot of very targeted traffic if you want to make any real money. Those affiliate offers also need to provide a high commission amount to you on each sale. You also need to ensure that the returns or chargebacks for those products or services are low. The last thing you want to do is to sell a product or service that provides very little value and gets returned often.
Likewise, ‘nofollowing’ your archive pages on your blog. Is this really a bad thing? You can get to the pages from the ‘tag’ index or the ‘category’ index, why put weight to a page that is truly navigational. At least the tag and category pages are themed. Giving weight to a page that is only themed by the date is crazy and does not really help search engines deliver ‘good’ results (totally leaving aside the duplicate content issues for now).
Finally, it’s critical you spend time and resources on your business’s website design. When these aforementioned customers find your website, they’ll likely feel deterred from trusting your brand and purchasing your product if they find your site confusing or unhelpful. For this reason, it’s important you take the time to create a user-friendly (and mobile-friendly) website.
Regarding nofollow on content that you don’t want indexed, you’re absolutely right that nofollow doesn’t prevent that, e.g. if someone else links to that content. In the case of the site that excluded user forums, quite a few high-quality pages on the site happened not to have links from other sites. In the case of my feed, it doesn’t matter much either way, but I chose not to throw any extra PageRank onto my feed url. The services that want to fetch my feed url (e.g. Google Reader or Bloglines) know how to find it just fine.
