Using ‘nofollow’ on untrusted (or unknown trust) outbound links is sensible and I think that in general this is a good idea. Like wise using it on paid links is cool (the fact that all those people are now going to have to change from JavaScript to this method is another story…). I also believe that using ‘nofollow’ on ‘perfunctory’ pages is also good. How many times in the past did you search for your company name and get you home page at number one and your ‘legals’ page at number two. Now, I know that Google changed some things and now this is less prominent, but it still happens. As much as you say that these pages are ‘worthy’, I don’t agree that they are in terms of search engine listings. Most of these type of pages (along with the privacy policy page) are legal ease that just need to be on the site. I am not saying they are not important, they are (privacy policies are really important for instance), but, they are not what you site is about. Because they are structurally important they are usually linked from every pages on the site and as such gather a lot of importance and weight. Now, I know that Google must have looked at this, but I can still find lots of examples where these type of pages get too much exposure on the search listings. This is apart from the duplicate content issues (anyone ever legally or illegally ‘lifted’ some legals or privacy words from another site?).
This guide is designed for you to read cover-to-cover. Each new chapter builds upon the previous one. A core idea that we want to reinforce is that marketing should be evaluated holistically. What you need to do is this in terms of growth frameworks and systems as opposed to campaigns. Reading this guide from start to finish will help you connect the many moving parts of marketing to your big-picture goal, which is ROI.
In the 1990s, the term Digital Marketing was first coined,.[10] With the debut of server/client architecture and the popularity of personal computers, the Customer Relationship Management (CRM) applications became a significant part of marketing technology.[citation needed] Fierce competition forced vendors to include more service into their software, for example, marketing, sales and service applications. Marketers were also able to own huge online customer data by eCRM software after the Internet was born. Companies could update the data of customer needs and obtain the priorities of their experience. This led to the first clickable banner ad being going live in 1994, which was the "You Will" campaign by AT&T and over the first four months of it going live, 44% of all people who saw it clicked on the ad.[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.

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.
Re: Cameron’s Comment. Google transparent? Maybe. Great products for users – yes… but they operate from lofty towers. Can’t get a hold of them. Can’t contact them. They are the ONLY company in the world with zero customer support for their millions of users. Who really knows what they are doing from one month to the month in regards to ranking sites… etc.

For the purpose of their second paper, Brin, Page, and their coauthors took PageRank for a spin by incorporating it into an experimental search engine, and then compared its performance to AltaVista, one of the most popular search engines on the Web at that time. Their paper included a screenshot comparing the two engines’ results for the word “university.”
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.
PageRank is one of many, many factors used to produce search rankings. Highlighting PageRank in search results doesn’t help the searcher. That’s because Google uses another system to show the most important pages for a particular search you do. It lists them in order of importance for what you searched on. Adding PageRank scores to search results would just confuse people. They’d wonder why pages with lower scores were outranking higher scored pages.
