I am not worried by this; I do agree with Danny Sullivan (Great comment Danny, best comment I have read in a long time). I will not be changing much on my site re: linking but it is interesting too see that Google took over a year to tell us regarding the change, but was really happy to tell us about rel=”nofollow” in the first place and advised us all to use it.
Search engines are smart, but they still need help. The major engines are always working to improve their technology to crawl the web more deeply and return better results to users. However, there is a limit to how search engines can operate. Whereas the right SEO can net you thousands of visitors and increased attention, the wrong moves can hide or bury your site deep in the search results where visibility is minimal.
How many times do we need to repeat the calculation for big networks? That’s a difficult question; for a network as large as the World Wide Web it can be many millions of iterations! The “damping factor” is quite subtle. If it’s too high then it takes ages for the numbers to settle, if it’s too low then you get repeated over-shoot, both above and below the average - the numbers just swing about the average like a pendulum and never settle down.
Was reviewing some competitive data and thought this was pretty interesting. I ran a batch analysis on Ahrefs of competitors. See attached screenshot. With just 603 backlinks, Our site is ranking up there with sites with 2x, 3x, 10x the number of backlinks/unique ips. Guessing some of this authority is coming from the backlinks program and general good quality of those links. Hard to speculate but nice to see. Ben R.
Prioritizing clicks refers to display click ads, although advantageous by being ‘simple, fast and inexpensive’ rates for display ads in 2016 is only 0.10 percent in the United States. This means one in a thousand click ads are relevant therefore having little effect. This displays that marketing companies should not just use click ads to evaluate the effectiveness of display advertisements (Whiteside, 2016).
A great number of public networks call themselves “private”. That’s not true. If the network is advertised, it cannot be private. We witnessed cases when Google destroyed such public networks and all the websites which had used them. They are easy to be revealed due to a huge number of outbound homepage links which are irrelevant to each other. Their posts are short, and they cannot really block SEO crawlers.
“An implied link is a reference to a target resource, e.g., a citation to the target resource, which is included in a source resource but is not an express link to the target resource,” Google said in its patent filing. “Thus, a resource in the group can be the target of an implied link without a user being able to navigate to the resource by following the implied link.”
9. Troubleshooting and adjustment. In your first few years as a search optimizer, you’ll almost certainly run into the same problems and challenges everyone else does; your rankings will plateau, you’ll find duplicate content on your site, and you’ll probably see significant ranking volatility. You’ll need to know how to diagnose and address these problems if you don’t want them to bring down the effectiveness of your campaign.
Quite simply, a backlink is one website mentioning another website and linking to it. It is not merely referencing the website or it’s web address. It has to be a clickable link using an href attribute within the code. It is the difference between http://www.moz.com and Moz. Even though the first example displays a URL, the search engines do not register this as a backlink, whereas the word that has a link (often underlined and in a different color), is.
Secondly, nofollow is also essential on links to off-topic pages, whether they’re internal or external to your site. You want to prevent search engines from misunderstanding what your pages are about. Linking relevant pages together reinforces your topic relevance. So to keep your topic silos clear, strategic use of the nofollow attribute can be applied when linking off-topic pages together.
For example this page. My program found almost 400 nofollow links on this page. (Each comment has 3). And then you have almost 60 navigation links. My real question is how much percentage of the PageRank on this page gets distributed to the 9 real links in the article? If it is a division of 469 which some SEO experts now are claiming it is really disturbing. You won’t earn much from the links if you follow what I am saying.
It is interesting to read the article which however as others have commented leaves questions unanswered. The ideal internal page rank flow is clearly down the hierarchy and back up again evidently and no page to page links down the line. If this effect is big enough to have provoked an algorithm change then it must be substantial. Removing those related product links altogether would improve ranking and degrade the user experience of the site which surely is undesirable. I suspect the lesser of two evils was chosen.
I say this because as Google is watching its own tailspin we normally see the relative growth the web in a matter of years working like the old web maker (spider+crawl) But a system that is exponential has the potential to become (node+jump). All the copy and wonderful content aside, the real use of the tool that is now called the internet will be discovering along the way, what some might call cybernetic or rather android-like mainframes for eco-stellar exploration, or instant language learning, or even mathematical canon though cloud computing.
2. Does a nofollowed INTERNAL link also bleed PageRank? Doesn’t that actively punish webmasters who use nofollow in completely . I think Danny makes the case that nofollow at the link level isn’t a cure for duplicate content, but many hosted sites and blogs don’t have the full range of technical options at their disposal. I myself use a hosted service that’s excellent for SEO in many ways but doesn’t give me a per-page HTML header in which to put a canonical link tag. Conclusion: Google would rather we NOT hide duplicate content if nofollow is the most straightforward way to do it.
At one point, backlinks developed a reputation of damaging a site’s credibility through search engines. This is due to “black hat” SEO practices would add 5,000 links to a website overnight (a practice that is still used today). While the website would launch to the top of search ranking results for a few weeks, it wouldn’t stay there, and the site’s credibility would be damaged because a few dozen servers with thousands of useless websites existed for the sole purpose of creating backlinks.
On another note, I would like to express my contempt for Google and its so called terms of service regarding the legitimate acquisition of links. why should it care if links are paid for or not? Thanks to the invention of pagerank, it is Google itself that has cancelled out reciprocal linking and has stopped people giving out links due to fear of them losing pagerank, and blogs and forums are worthless thanks to the nofollow trick. so it is now impossible to get decent links organically, without having to pay for them, and those who do give out free links are considered fools. Google has brought this dilemma on itself, and yet it seems like punishing us for trying to get links other than freely! Face facts, no one is going to link to someone without getting a link in return! google has invented pagerank which is like a currency, and so people expect to be paid for links, as giving out links devalues their pagerank and so compensation is now required. It is forcing people to use underhand methods to get links, mostly the ‘paid’ variety.
One thing is certain: interlinking sites doesn't help you from a search engine standpoint. The only reason you may want to interlink your sites in the first place might be to provide your visitors with extra resources to visit. In this case, it would probably be okay to provide visitors with a link to another of your websites, but try to keep many instances of linking to the same IP address to a bare minimum. One or two links on a page here and there probably won't hurt you.
PageRank is often considered to be a number between 0 and 10 (with 0 being the lowest and 10 being the highest) though that is also probably incorrect. Most SEOs believe that internally the number is not an integer, but goes to a number of decimals. The belief largely comes from the Google Toolbar, which will display a page's PageRank as a number between 0 and 10. Even this is a rough approximation, as Google does not release its most up to date PageRank as a way of protecting the algorithm's details.
