Thanks for the comment, I would not say it is impossible to create high quality backlinks from scratch without content, you just need to do a review on competitor backlinks and see if their are any easy targets. We have had some good luck in the education space acquiring links on the same pages as competitor from PR5+ edu sites. It all revolves around the outreach strategy in which you put in place.
Website saturation and popularity, or how much presence a website has on search engines, can be analyzed through the number of pages of the site that are indexed by search engines (saturation) and how many backlinks the site has (popularity). It requires pages to contain keywords people are looking for and ensure that they rank high enough in search engine rankings. Most search engines include some form of link popularity in their ranking algorithms. The following are major tools measuring various aspects of saturation and link popularity: Link Popularity, Top 10 Google Analysis, and Marketleap's Link Popularity and Search Engine Saturation.

While network marketing companies financially incentivize their distributors to sell their products, just like in affiliate marketing, it’s not just the money that motivates word of mouth and it’s not money alone that will make the sale. It’s got to be a game-changing or life-changing product or service to give people something talk about with positive emotions like excitement and enthusiasm, so that the people they talk to want to be a part of it (and fear being left out). If people believe the company has a lousy product and compensation plan, then people won’t feel motivated to talk about it or have persuasive reasons to tell others to buy into it as well. If people don’t believe in the person or company selling it, the seller won’t generate any sales. This is why brands can charge more and generate billions in value, like these top 10 most valuable brands in the world:
The leading search engines, such as Google, Bing and Yahoo!, use crawlers to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. The Yahoo! Directory and DMOZ, two major directories which closed in 2014 and 2017 respectively, both required manual submission and human editorial review.[39] Google offers Google Search Console, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that are not discoverable by automatically following links[40] in addition to their URL submission console.[41] Yahoo! formerly operated a paid submission service that guaranteed crawling for a cost per click;[42] however, this practice was discontinued in 2009.
Click through rates: Searches using terms that denote high purchase intent such as product or brand-specific keywords will get more clicks than organic results. The advantage of paid search can clearly be seen in the Internet retailers MarketLive Performance Index data. For the year 2013 as a whole, PPC accounted for 36.5% of search traffic but an outsized 47.9% of revenue from search.
As you can see by the example above, organic marketing tactics are natural, authentic, and value-based. The benefits that businesses reap from these tactics are cultivated over longer periods of time, ultimately helping you build a brand that customers want to visit regularly. And although you’re doing less “pushing” with organic marketing, when done right you can still generate a steady stream of loyal traffic. Remember, this is about building high-value brand equity and industry authority with your customers. You’re not just attempting to drive sales here; you’re working hard to engage and educate your target audiences.  
This topic seems actually quite controversial. Google answered the question by what could be taken as a denial. But their answer was kind of open to interpretations. And on the other hand, there are studies (one of them from Moz) that showed linking out has an impact. So, how can you be so assertive? Is it something that comes out from your own experiments?

Although it may have changed slightly since BrightEdge published its report last year, the data still seem to hold true. Organic is simply better for delivering relevant traffic. The only channel that performs better in some capacities is paid search ads, but that is only for conversions, not overall traffic delivery (Paid Search only accounted for 10 percent of overall total traffic).
