Nofollow has been around for 14 years and is the’one of the simplest HTML tags that’an SEO-ER must master. In particular, those of’between you who do SEO and who need’improving the performance of their website will need to pay attention to this important factor.

So read right now’article and accumulate the most useful knowledge about the Nofollow tag and Follow links on your own!

1. What’do’a real nofollow link?

Rel nofollow links are hyperlinks that contain the rel=”nofollow” tag. In fact, nofollow links will not be crawled by Google because Google will not pass ad text to them.’anchor or PageRank. In other words, The search engine ranking’Destination URL will not be affected by the nofollow link.

  • Difference Between Nofollow and Follow Links

Ordinary Internet users will not be able to distinguish between Nofollow and Follow links, unless’they do take a closer look at their HTML code. For instance: SEODO and SEODO Nofollow and Follow links respectively. We will analyze the HTML to see the difference between the two

No following:

Follow the links:

first blue text

The HTML is identical to the’exception of the’added tag. rel=”no tracking”.

By placing the robots meta tag with “nofollow” in the title, you can configure the nofollow with all link on a website. However, you should use the nofollow tag in a more targeted way because it also has a feature that allows a person to be unable to search for certain links on the page while they are on the page.’others can still see it.

Next, we’ll take a look at the’history of rel=”nofollow” to better understand its power!

2. Why was rel=”nofollow” born?

Google for the first time introduce nofollow tag in 2005 to combat comment spam.

If you’re a blogger (or blog reader), you know very well the people who try to’improve their site’s search engine rankings by posting related comments like “Visit the pharmacy website and get instant deals…”. VS’do’we call comment spam, we don’t’don’t like it either and we tested a new beacon to block it. Now when Google sees the’attribute (rel=”nofollow”) on hyperlinks, these links will not receive any credit as we rank the sites in our search results. He is not’don’t act’a negative vote for the site on which the comment was posted; vs’is just a way to s’ensure that spammers do not take advantage of’misusing public areas like blog comments, following and reference lists.

After that, Yahoo!, Bing and some other search engines also declare their commitment to the nofollow tag.


These days, WordPress adds the nofollow tag to comment links by default, as do many other CMSs. So even if you don’t’have never heard of nofollow links before, rest assured that spammy commenters on your blog are unlikely to get any SEO benefit from your efforts.

However, if you’re concerned that your comment isn’t being tracked, here’s how to check:

  1. Search comments
  2. Right click on the link
  3. Click “Check”
  4. View the highlighted HTML code.

rel="no tracking"

If you see the rel=nofollow tag, it n’is already no longer followed. If not’is not the case, it was followed.

2009: Google against the sculpture of PageRank

PageRank surrounds a webpage through internal links (links of’one site to another).

For example, part of the Page Rank of this article is transmitted to d’other pages of our site through’hyperlinks such as this. In general, a higher PageRank means higher rankings. Gary Illyses l’confirmed the’last year.

rel="no tracking"

However, the PageRank n’is transmitted only by followed links, not by nofollow links.

This has always been the case, but the way PageRank is shared between followed links on a page has changed over the years.

Before 2009, it worked like this:

If you have dad link on a page and one of the number of’between them’is not tracked, the total Page Rank is divided between of them follow link.

rel="no tracking"

Unfortunately, some people have started taking advantage of this technique to manipulate rankings by building a PageRank rating around their web pages.

In d’other words, they will not follow links to their unimportant pages to allow maximum PageRank transfer to their “d” pages.’silver “.

Google announced the changes to apply this method from scratch in 2009:

So what happens when you have a page with “ten PageRank” and ten outbound links, and five of those links are unfollowed? […] Initially, five links without nofollow will have two points per PageRank […] There are more’a year, Google changed the way PageRank is so that five links with no nofollow will generate one PageRank score per link.

Here are some before and after illustrations:

rel="no tracking"


PageRank is a sophisticated beast. It’s been ten years since Google made this change. Although’they don’t’have publicly announced any changes to the way PageRank has operated in recent years, it is likely that’at least some of the changes have taken place behind the scenes.

Although the’PageRank adjustment is no longer important thingbut “not following” some internal links can help prioritize the’exploration, because Google n’do not explore nofollow links.

Search engine crawlers can’t connect or s’register as a member of your forum, there’so there is no reason to’invite Googlebot to follow a link “s’register here” or “log in”. L’use of nofollow on these links allows Googlebot to’explore d’other pages you want to see in the’Google index.

However, it s’is about’a somewhat advanced subject, we’so we won’t go into the details here.

2013 and after: Google against paid links.

Google ranks links’buying or selling via PageRank as violate their webmaster guidelines.

Therefore, Not all paid links should be followed.

This was the case for many years, even well before 2013.

However, d’after what we can see google has become more and more concerned about the’effect of undisclosed paid links on their algorithm this time…and ever since.

But in short: Google wants to reward earned links not right paid links.

People treat links like editorial votes. They’associate with something because it ignites the passion in them. VS’is something’interesting. They want to share it with friends. There are several reasons why they would want to bookmark that particular link.

The problem is something paid links doesn’t seem different earned links. Think about the difference between a link in a paid review and a link in an unpaid review.

At first glance, the two links will look exactly alike. VS’is why there must be a way to disclose a bounty to Google.

Think of it like this: There are two ways to’get an Oscar:

Option 1: Live to do, continually hone your skills, and work hard for years.

Option 2: Buy 6 for $8.97 on Amazon

The nofollow tag (on paid links) with the’$8.97 sticker on your fake Oscar will be a sign to Google that you don’t’you didn’t earn this money legally and therefore don’t deserve it..

3. So how can placing rel nofollow tags help SEO?

Let’s briefly summarize what Google has to say about how they handle no-follow links:

Google does not pass PageRank or text to’anchoring via these links.

It all seems pretty clear until’until you read the sentence before it:

In general, we do not follow them. This means that Google does not pass PageRank or link text through these links.

In generalI think this statement is more vague than’she shouldn’t’to be and implies that’they follow nofollow links in some cases.

What these cases might be, no one knows.

Some people think that all nofollow links always pass a certain PageRank. Some people think Google passes PageRank to some nofollow links, but not all. D’others think that people read too much in words that’have not changed for 7 years.

Earlier this year we studied 44,589 SERPs to see s’there is a correlation between Google rankings and various backlink attributes, including the’one is the number of backlinks followed.

Here is what we found:

rel="no tracking"

The correlation between the number of “dofollow” backlinks is slightly lower than the total number of backlinks.

“Here perhaps is an indication that Google values ​​some nofollow links from strong sites more than followed links from weak sites. – Tim Soulo, CMO at Ahrefs Ghi

This finding is indicative only. L’main objective of this study n’was not d’analyze the’impact of nofollow links versus followed links and therefore we should not try to focus on this factor.

But even if we assume that unfollowed links n’have no effect direct to SEO, they may still have Indirect due to:

3.1. Diversify your link infrastructure

The natural profile of backlinks is very diverse.

Some links are followed and d’others no. This fact is unavoidable because some people will inevitably link to you through non-following links…even though you might wish they didn’t.

Also, most of the backlinks you get from the following places are untracked:

  • Social networks (Facebook, Twitter, YouTube, etc.)
  • Forums (Reddit, Quora…)
  • Press release
  • Book of’gold (hello, 1998!)
  • Wikipedia (hint: Who can also edit a Wikipedia page)
  • Pingbacks
  • Case

In short, if a site n’a only followed backlinks or a clearly high percentage of followed backlinks, c’is a sign that’something confusing is happening. .

To check the ratio of followed links to non-followed links for a website or web page, use Insight in Ahrefs Site Explorer.

Site Explorer > enter n’any domain, URL or subfolder > Overview

rel="no tracking"

It seems that 85% of the referring domains (linking sites) to the Ahrefs blog are traced.

Not good or bad? Honestly, as long as’there is diversity here, c’is a good sign.

What you don’t want to see’is 100% “dofollow” or something close because it’is a clear sign of manipulation. From experience, I would say that’between 60 and 90% is normal – but this range n’is not the default. If you see signs of foul play, do some additional research to verify.

3.2. Generate traffic, and the traffic will generate followed links

Links are not only useful for SEO purposes. They also drive referral traffic.

VS’is why we are so active on Quora.

If you n’never heard of Quora before, c’is a Q&A site where anyone can answer questions that people post. In these answers, Quora allows links to relevant resources.

They’is about’a recent response posted by our marketing manager, Rebecca Bekwhere it links to the Ahrefs blog:

rel="no tracking"

Unfortunately, since not all outgoing links on Quora are followed, this link does not’has no direct SEO effect.

But here’s the fun part:

If we check Ahrefs Report backlinks in Site Explorer give ahrefs.com and filter only “dofollow” links, here is the’one of the many backlinks we see:


Now let’s take a closer look at the page’introduction (page extracted from followed links):

rel="no tracking"

The only reason we get follow is because the’Author of this post came across Rebekah’s Quora answer. In d’In other words, a no-follow link leads indirectly to a followed link.

So remember this: for someone’one connects to you, three things must happen in this order:

  1. Last name see your content
  2. Last name favorite your content
  3. Last name introduce to d’others (via links on their websites)

Because nofollow links can be useful in the first place, they are often the catalyst for followed links.

3.3. Avoid penalties’google penalty algorithm by setting rel nofollow

Sometimes there are good reasons to pay for links.

If a website receives a lot of traffic, it may make perfect sense to’purchase a sponsored item on this site. And if you’re paying a lot for a feature, you’ll probably want to include a backlink so readers can easily find your site.

Problem? Google states that paid links are tracked against their webmaster guidelines.

That said, the SEO community as a whole is divided into two camps:

  • Those who believe that Google perhaps correctly identify paid links algorithmically.
  • Those who believe that Google can not correctly identify paid links algorithmically.

For’For now, let’s assume camp #2 is true and Google is having trouble identifying all the paid links. It means that you are sure of’buy and sell links to your heart’s content, n’is this not ? Not so fast.

Google has a tool Allows anyone to report a site to buy or sell links.

rel="no tracking"
Google tool to report paid links.

We can understand that’you should not be afraid of Google but worry about your competitors.

Think about it: if a competitor sees you ranking well for their target keyword and’he uses a tool like site explorer’Ahrefs to research your backlinks, only to discover follower links like this:

rel="no tracking"

So why don’t they report you?

If this leads the’Google Spam Enforcement team to examine your site, discover paid links and issue a penalty, this will further reduce the competition for you.’they compete in the SERPs.

This suggests to us:

4. Website optimization in case of issues with nofollow and follow link

Following backlinks that violate Google’s Webmaster Guidelines is very risky.

The same goes for outgoing links from your site that are not followed.

But he doesn’t’does not only act’outrage from Google (c’that is to say sadness). It can also happen that some unfollowed internal links harm your SEO performance.

The following is a quick assessment to help identify and eliminate these problems.

4.1. Make sure nofollow and dofollow backlinks have a purpose

For the most part, people n’use the wrong anchor when’they will link to your site. VS’is why links follow with exact match anchors perhaps is a sign of backlink manipulation.

To find them, use the Anchors report in Ahrefs Site Explorer.

Site Explorer > enter your domain name > Anchors > dofollow filter

rel="no tracking"

Here we see that most of the anchors on this site are branded or generic (hidden for security), but nineteen sites (referring domains) use the’expression “short-term loan” as an anchor.

If we press the caret and then the referring domains, we can see what these sites are.

Then, if we press the caret again, we can see the context of all the links for each domain.

rel="no tracking"

Here are some basic guidelines for managing the different types of links you’ll find here:

  • Buying links from low quality sites. Request removal of the link (preferred) or’lack of follow-up. Disavow at site or domain level s’they don’t.
  • Profile link published by l’guest. Have you ever used keyword rich anchors in the biography of the’author of the’guest post? Ask the person in charge of this site to replace the keyword-rich link with a branded link. Or, if you want the link to remain permanent, tell it to unfollow.
  • Widget link. Change the HTML of your widget so that the link is not tracked. Ask people who have embedded your extension to unfollow the link.
  • Website link. The link request n’is not followed or replaced by a branded link.

Note that the links that follow an exact match n’not always indicate poor quality or paid links. Such links can occur spontaneously and under legitimate circumstances.

VS’is why you should always make sure to’investigate links thoroughly before disavowing them or asking not to follow them.

If you don’t, you could be doing more harm than good.


For large sites, there may be hundreds or thousands of’different web anchors anchors . Screening of each’them can take time.

Here is a quick tip you can use:

All d’First, export the full list of tracked anchors.

Site Explorer > import your domain > Anchors > add a “dofollow” filter > Export > CSV

Then copy them and paste them into Ahrefs Keyword Explorer in batches of up to’10,000 at a time.

Click Search to generate a report, then sort by CPC column from top to bottom.

rel="no tracking"

Since high CPC anchors are more likely to’be spam anchors, this will result in spam anchors at the top of the list.

Finally, look for anchors that look like spam in anchors in Site Explorer and investigate further.

rel="no tracking"

4.2. Set the rel nofollow tag for all backlinks used for advertising

Since sponsored posts should always be untracked.

VS’is because you’re actually paying for the link, so it won’t pass PageRank.

To find such links, search for the word “sponsored” in Ahrefs Report backlinks for your site in Site Explorer.

Site Explorer > Backlinks > search “sponsored” > filter “dofollow”

rel="no tracking"

Reaching out and asking for such a link does not’object of’a trace.

4.3 Blocking tracking links’inside the website to the’outside

Did you know that Forbes n’tracked all of its outgoing links in 2017?

This decision comes after’they noticed that some of their contributors were selling follow links from their articles. Because’they have so many contributors, they decided that’they couldn’t check all the links on the site and so they chose the’lazy option to not track everything.

Why is this relevant?

Because if you ever accept publications from’guests on your site or if you have user-generated content, you may experience the same problem.

To know if it’is the case, see your outgoing anchors in Ahrefs Site Explorer.

Site Explorer > enter your domain > Outbound links > Anchor > add the “dofollow” filter

rel="no tracking"

Look for suspicious words and phrases that you don’t expect to see on your site, and remove or unsubscribe from any links that seem manipulative (e.g., multiple-keyword anchors in post bios, blog posts, etc.)’guests, etc).

Why C’is important, Google Explain VS’is better :

If you cannot or do not want to guarantee the content of the pages which you access from your site – for example, comments from’untrusted users or dbook entries’gold – you should not follow follow links. This can discourage spammers from targeting your site and will prevent your site from accidentally passing PageRank to bad neighborhoods on the web.


Use the pro tip from’Step 1.

4.4 Set the rel nofollow tag for all links using website ads

Have you ever accepted a sponsored post on your website? Are you sure you are not following the link?

If you n’are not sure, it may be worth checking.

To do this, search in Google website: yourwebsite.com “sponsored posts”

rel="no tracking"

Open the results one by one and find the sponsored link.

If you have already installed Chrome No Track Extension, all nofollow links on the page will be bookmarked – so sponsored links should definitely be bookmarked. Otherwise, it’is a followed link.

rel="no tracking"

Confirm that it’is the case by digging into the HTML.

Right-click on the link, hit “Inspect” and look for the rel=”nofollow” tag.

rel="no tracking"

S’he is absent,’is a followed link and you need to add the nofollow tag.

4.5. Check internal nofollow on website

Internal links should not be followed unless’they point to unimportant pages or pages that you want to exclude from the’search engine index.

To find internal no-follow links, use Best Links in Ahrefs Site Explorer.

Site Explorer > enter your domain > Top Links > switch to Internal > sort by “nofollow” column

rel="no tracking"

If you see pages that don’t follow internal links, tap the number to see d’where these links come from and investigate further. It’s possible that these circumstances make perfect sense (for example, unfollowed internal links to the login page).

However’he does’there’s no obvious reason why the links aren’t being followed, remove the nofollow tag.

VS’is the case here. For some reason we have an untracked link d’one blog post to another.
