If I was able to write a blog post that was popular and it got lots of comments, then any links that I would have put in the body text would be devalued with each additional comment – even with ‘no follow’ being on the commenter’s links. So it would seem that in some sort of perverse way, the more popular (by comments) a page is, the less page rank it will be passing. I would have to hope that the number of inbound links it gets would grow faster than the comments it receives, a situation that is unlikely to occur.
When deciding on your niche, you have to actually start a blog or a website that's going to be your online hub. This is where your anchor content is going to live. Everything else will link to here. All the ads you run and traffic you drive through social media or SEO or anything else will all come here. You need a custom domain and a professional looking site if you want anyone to take you seriously.
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.
What are backlinks doing for your SEO strategy? Well, Google considers over 200 SEO ranking factors when calculating where a page should rank, but we know that backlinks are one of the top three (the other two are content and RankBrain, Google’s AI). So while you should always focus on creating high-quality content, link-building is also an important factor in ranking your pages well on Google.

Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines' algorithms, or by a manual site review. One example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices.[53] Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google's list.[54]

While most search engine companies try to keep their processes a secret, their criteria for high spots on SERPs isn't a complete mystery. Search engines are successful only if they provide a user links to the best Web sites related to the user's search terms. If your site is the best skydiving resource on the Web, it benefits search engines to list the site high up on their SERPs. You just have to find a way to show search engines that your site belongs at the top of the heap. That's where search engine optimization (SEO) comes in -- it's a collection of techniques a webmaster can use to improve his or her site's SERP position.
Although online marketing creates many opportunities for businesses to grow their presence via the Internet and build their audiences, there are also inherent challenges with these methods of marketing. First, the marketing can become impersonal, due to the virtual nature of message and content delivery to a desired audience. Marketers must inform their strategy for online marketing with a strong understanding of their customer’s needs and preferences. Techniques like surveys, user testing, and in-person conversations can be used for this purpose.
As you might know, backlinks and all marketing strategies are dependent on the competition and existing trends in your niche. So if the blogs and marketers in your country are still using older tactics like web 2.0 backlinks and blog comments, then does it even make sense to go for tedious strategies like outreach? Does it even warrant a good business ROI?
To prevent users from linking to one version of a URL and others linking to a different version (this could split the reputation of that content between the URLs), focus on using and referring to one URL in the structure and internal linking of your pages. If you do find that people are accessing the same content through multiple URLs, setting up a 301 redirect32 from non-preferred URLs to the dominant URL is a good solution for this. You may also use canonical URL or use the rel="canonical"33 link element if you cannot redirect.

So, as you build a link, ask yourself, "am I doing this for the sake of my customer or as a normal marketing function?" If not, and you're buying a link, spamming blog comments, posting low-quality articles and whatnot, you risk Google penalizing you for your behavior. This could be as subtle as a drop in search ranking, or as harsh as a manual action, getting you removed from the search results altogether!
And looking at say references would it be a problem to link both the actual adress of a study and the DOI (read DOI as anything similar)? Even if they terminate at the same location or contain the same information? The is that it feels better to have the actual adress since the reader should be able to tell which site they reach. But also the DOI have a function.

The goal of SEO is to get a web page high search engine ranking. The better a web page's search engine optimization, the higher a ranking it will achieve in search result listings. (Note that SEO is not the only factor that determines search engine page ranks.) This is especially critical because most people who use search engines only look at the first page or two of the search results, so for a page to get high traffic from a search engine, it has to be listed on those first two pages, and the higher the rank, the closer a page is to the number one listing, the better.  And whatever your web page's rank is, you want your website to be listed before your competitor's websites if your business is selling products or services over the internet.
Having a ‘keyword rich’ domain name may lead to closer scrutiny from Google. According to Moz, Google has “de-prioritized sites with keyword-rich domains that aren’t otherwise high-quality. Having a keyword in your domain can still be beneficial, but it can also lead to closer scrutiny and a possible negative ranking effect from search engines—so tread carefully.”
From a customer experience perspective, we currently have three duplicate links to the same URL i.e. i.e. ????.com/abcde These links are helpful for the visitor to locate relevant pages on our website. However, my question is; does Google count all three of these links and pass all the value, or does Google only transfer the weight from one of these links. If it only transfers value from one of these links, does the link juice disappear from the two other links to the same page, or have these links never been given any value?
The Google algorithm's most important feature is arguably the PageRank system, a patented automated process that determines where each search result appears on Google's search engine return page. Most users tend to concentrate on the first few search results, so getting a spot at the top of the list usually means more user traffic. So how does Google determine search results standings? Many people have taken a stab at figuring out the exact formula, but Google keeps the official algorithm a secret. What we do know is this:
What an article… thank you so much for the priceless information, we will be changing our pages around to make sure we get the highest page rank available to us, we are trying to get high page rank sites to link to us, hopefully there is more information out there to gather as we want to compete within our market to gain as much market-share as possible.
I don’t know how you do it without having a strong team of employees building backlinks for you. I love your blog and all the guidance you provide. I have found trying to build backlinks on your own is one of the most time consuming activities there is. Obviously if you have a specific product or service you are wishing to share getting more customers and visitors to your business is essential. You make it look easy. Thanks again for all your guidance.
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.
