Also, by means of the iterative calculation, the sum of all pages' PageRanks still converges to the total number of web pages. So the average PageRank of a web page is 1. The minimum PageRank of a page is given by (1-d). Therefore, there is a maximum PageRank for a page which is given by dN+(1-d), where N is total number of web pages. This maximum can theoretically occur, if all web pages solely link to one page, and this page also solely links to itself.
When would this be useful? If your site has a blog with public commenting turned on, links within those comments could pass your reputation to pages that you may not be comfortable vouching for. Blog comment areas on pages are highly susceptible to comment spam. Nofollowing these user-added links ensures that you're not giving your page's hard-earned reputation to a spammy site.

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)
Example: A blogger John Doe writes a very interesting article about a sports event. Another blogger Samantha Smith doesn’t agree with John’s article and writes about it in another article for an online magazine. She links to John’s article, so that her readers can understand both point of views. John’s blog gets a valuable backlink. On the other hand, Samantha’s article gets popular and many other websites link to her article. Samantha’s website gets many new backlinks. Even though John only got one backlink for his article, the value of his backlink is increased by the backlinks Samantha’s article generated.
But how do you get quoted in news articles? Websites such as HARO and ProfNet can help you to connect with journalists who have specific needs, and there are other tools that allow you to send interesting pitches to writers. Even monitoring Twitter for relevant conversations between journalists can yield opportunities to connect with writers working on pieces involving your industry.

# nofollow is beyond a joke now. There is so much confusion (especially when other engines’ treatment is factored in), I don’t know how you expect a regular publisher to keep up. The expectation seems to have shifted from “Do it for humans and all else will follow” to “Hang on our every word, do what we say, if we change our minds then change everything” and nofollow lead the way. I could give other examples of this attitude (e.g. “We don’t follow JavaScript links so it’s ‘safe’ to use those for paid links”), but nofollow is surely the worst.

##### Just like the new structure on JavaScript links and them now carrying weight and being crawlable, the PageRank sculpting change is understandable. Google now can and wants to index more of the web (JavaScript link change). Google wants to reverse a method that can only help people in the know (PageRank sculpting change). Logically, all is very understandable.

Email marketing - Email marketing in comparison to other forms of digital marketing is considered cheap; it is also a way to rapidly communicate a message such as their value proposition to existing or potential customers. Yet this channel of communication may be perceived by recipients to be bothersome and irritating especially to new or potential customers, therefore the success of email marketing is reliant on the language and visual appeal applied. In terms of visual appeal, there are indications that using graphics/visuals that are relevant to the message which is attempting to be sent, yet less visual graphics to be applied with initial emails are more effective in-turn creating a relatively personal feel to the email. In terms of language, the style is the main factor in determining how captivating the email is. Using casual tone invokes a warmer and gentle and inviting feel to the email in comparison to a formal style. For combinations; it's suggested that to maximize effectiveness; using no graphics/visual alongside casual language. In contrast using no visual appeal and a formal language style is seen as the least effective method.[48]
Less than 2 years ago one could promote a website within a month with the help of PBN (Private Blog Network). Then Google created “a sandbox” which made a site owner wait no less than 3 months before the effect of PBN backlinks turned to be visible. There are two more negative factors: risk and financial investment. You will realize that neither your wasted time nor money were worth it. That’s why it’s better to rely on proper backlinks from real sites.
```You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
