Links are the currency of the web. The webpages that have plenty of them are deemed “authoritative” and are rewarded with high rankings in Google. While pages that don’t have any are bound to obscurity.
This guide will teach you how to get quality links that move the needle without risking a Google penalty. We created it with absolute beginners in mind and made sure to pack it with plenty of actionable advice that you can start implementing right away.
Link building is the process of getting other websites to link to pages on your website. Its purpose is to boost the “authority” of your pages in the eyes of Google so that these pages rank higher and bring more search traffic.
Why is link building important?
According to Google’s Andrey Lipattsev, links are one of the three major ranking factors in Google. So if you want your website’s pages to rank high in search, you will almost certainly need links.
Google and other search engines look at links from other sites as “votes.” These votes help them identify which page on a given topic (out of thousands of similar ones) deserves to rank at the very top of the search results.
Thus, as a general rule, pages with more backlinks tend to rank higher in search results.
Links aren’t the answer to everything
Links are incredibly important for ranking well. And it is quite rare that you will outrank pages that have a lot of strong links—unless you get just as many. And yet, links aren’t the only factor that Google uses to rank pages.
So if you build lots of links to your page and it still ranks poorly, look into other ranking factors that might prevent you from ranking well.
How to build links
Conceptually, most link building tactics and strategies fall into one of the following four buckets:
1. Adding links
If you can go to a website that doesn’t belong to you and manually place your link there, that’s called “adding” a link. The most common tactics that fit into this category are:
Business directory submissions.
Social profile creation.
Posting to forums, communities, and Q&A sites.
Creating job search listings.
Building links via those tactics is very easy to do. And for that exact reason, such links tend to have very low value in the eyes of Google. In some cases, they may even be flagged as spam.
Other than that, these kinds of links barely give you any competitive advantage. If you can go to a website and manually place your link there, nothing stops your competitors from doing the same.
However, you shouldn’t ignore this group of link building tactics entirely. Each of them can actually be quite beneficial for your online business for reasons other than SEO.
Let me elaborate with a couple of quick examples:
Business directories – If you’re doing SEO for a restaurant website, you should definitely list it in three to five major directory sites like Yelp, Tripadvisor, Allmenus, Grubhub, etc. Those links won’t be particularly strong ones, but you might get some actual customers from them.
Industry forums – If you know some active forums or communities where your target audience is hanging out, you should definitely be active there too. But merely spamming your links without trying to add value to conversations will quickly get you banned from these places.
As you can tell, each of these strategies can be quite meaningful. But if someone offers you to do any of the above at scale (i.e., register your site at a hundred business directories or create a hundred social media profiles)—stay away from that. These kinds of “hacks” are a waste of money at best and might even get your website penalized at worst.
While looking for more ways to “add” links to other websites, you might come across tactics that mention “web 2.0s” and “bookmarking sites.” Those things used to work some 15 years ago, but you shouldn’t waste your time on them today.
2. Asking for links
As the name suggests, this is when you reach out to the owner of the website you want a link from and give them a compelling reason to link to you.
That “compelling reason” is an absolutely essential success factor. The people you reach out to don’t care about you and your website (unless you’re some sort of celebrity) and, thus, they have zero incentive to promote you or your work.
So before you ask them to link to you, ask yourself: “What’s in it for THEM?”
Here are some of the link building tactics and strategies that fall into this category, along with a briefly defined “compelling reason” that they’re based off:
These strategies seem to make quite some sense, right? But as soon as you send your first email request, you’re likely to face the harsh reality—your “compelling reason” isn’t compelling enough:
Your guest post isn’t good enough.
Your resource isn’t worthy of a mention.
Your “skyscraper” isn’t as “tall” as you thought it was.
The truth is it is incredibly hard to persuade random website owners to link to you. Either you have a one-of-a-kind outstanding resource that will genuinely impress them, or you’re well known in your field and they will be happy to fix you a link as a favor.
If it’s none of the two, you better handle rejection well. Because for every 100 emails, 98 will either not reply or say “no.”
And that is exactly the reason why many SEOs started looking for ways to make it worthwhile for the other party and offer something in return for a link, such as:
So there you have it. The candid ways of asking for links have a rather low success rate. But as soon as you try to “sweeten the deal,” you’re entering Google’s minefield.
At this point, it may seem that I’m dissuading you from using tactics and strategies listed in this group. I’m not. I’m merely suggesting that you ensure your content is outstanding before reaching out to hundreds of people.
3. Buying links
Let’s get this straight from the get-go:
We don’t recommend that you buy links!
If you don’t have lots of experience with it, you’re likely to waste lots of money on useless links that will have zero impact on your rankings. Or even get your website penalized.
However, we will be putting you at a disadvantage if we don’t disclose the fact that many people in the SEO industry do “buy” links in all sorts of ways and manage to get away with it.
So if you’re willing to risk the well-being of your website and buy links, please look for advice on doing that “safely” elsewhere—because here at Ahrefs, we don’t teach that.
4. Earning links
You “earn” links when other people link to the pages on your website without you having to ask them to do so. This obviously doesn’t happen unless you have something truly outstanding that other website owners will genuinely want to mention on their websites.
But people can’t link to things that they don’t know exist. So no matter how awesome your page is, you’ll need to invest in promoting it. And the more people see your page, the higher the chance that some of them will end up linking to it.
Later in this chapter, I’m going to share some tactics and strategies that will help you both create “link-worthy” content and promote it to relevant audiences who might end up linking to it.
Bonus: Preserving links
Technically, preserving your hard-earned links does not really fall under the definition of “link building.” But when you lose an important backlink, the “vote” that it was sending to Google is also lost. So it is fairly important to preserve your hard-earned links.
Monitoring your lost backlinks and reaching out to a website owner when an important link goes missing (also known as “link reclamation”)
Both of these things are easy to do with Ahrefs’ Site Explorer. The Best by links report will help you find the 404 pages with links. While the Backlinks report has a handy “Lost” filter, which will show you all links that were recently lost.
One important caveat, though. You don’t need to bother about every single link that goes missing. You just need to preserve the most important ones. And that is exactly what we’re going to talk about next.
What makes a good link?
Nobody knows for sure how exactly Google measures the value of each link. But there are some general concepts of evaluating links that the SEO community believes to be true:
Nofollow vs. follow
As you already know, Google sees links as “votes” that a given page deserves to rank well. But a link from techcrunch.com can’t possibly have the same power as a link from your friend’s personal blog, right? (Unless, of course, your friend is Tim Ferriss.)
Well, Google has consistently denied that some sort of sitewide website authority metric exists in its system. And yet, many SEOs believe that the concept of “website authority” makes too much sense to completely discount it.
What is more important, though, is the authority of the actual page that is linking to you. It’s one thing to be mentioned in a TechCrunch article that goes unnoticed, and it’s an entirely different case if that article “breaks the internet” and gets referenced on dozens of major news websites.
In other words, a page that has some strong votes of its own will cast a stronger vote compared to a page with no votes. This simple principle lies at the core of Google’s famous PageRank algorithm.
Back in the day, Google even provided a browser toolbar, which displayed the PageRank of any URL you visited. But this toolbar was deprecated more than 10 years ago. Which gave SEO tool providers an opportunity to fill that gap and develop their own authority metrics.
If other prominent websites on the subject link to the page, that’s a good sign that the information is of high quality.
3. Anchor text
Just in case you’re not already familiar with the term, “anchor text” is a clickable snippet of text that links to another page. In many cases, it succinctly describes what the linked page is about.
So it’s no surprise that Google uses the words in the anchor text to better understand what the referenced page is about and what keywords it deserves to rank for. In fact, Google’s original PageRank patent talks about this quite explicitly:
Google employs a number of techniques to improve search quality including page rank, anchor text, and proximity information.
So how do you leverage anchor text when building links?
Well, it’s better that you don’t. The more you try to control how different pages link to you and shoehorn all the “right words” into the anchor text of your backlinks, the higher the chance that Google will suspect manipulation and penalize you for that. So it’s better to just let the author of the linking page decide how they want to reference your page.
4. Nofollow vs. follow
“Nofollow” is a link attribute that tells Google that the linking page will rather not give its vote to the page that it is referencing.
It also introduced two new link attributes along with this announcement:
rel=“UGC” should be applied to user-generated links, e.g., blog comments and forum posts.
rel=“sponsored” should be applied when the link is part of an advertisement, sponsorship, or some other compensation agreement.
As a general rule, you want to be getting “followed” links (i.e., links that don’t have any of the aforementioned attributes) because these are the ones that are supposed to cast the strongest votes.
However, if you see an opportunity to get a nofollowed link from a relevant high-authority page, you should absolutely take it.
A good example is Wikipedia, where all outgoing links are nofollowed. Getting a link from Wikipedia is incredibly hard, which is why many SEOs are convinced that those links are quite valuable in the eyes of Google.
Google’s reasonable surfer patent talks about how the likeliness of a link being clicked may affect how much authority it transfers. And placement of a link on a page is one of the few things that can affect its CTR.
Let’s say there’s a webpage that consists of three blocks: content, sidebar, and footer. As a general rule, links in the content will get more clicks because the content block gets the most attention from visitors.
One other thing that can affect the CTR of a link is how high on the page it appears. Readers are more likely to click links at the very beginning of the article rather than the ones at its very end.
When building links to your website, there are three destinations where you can point them:
Your linkable assets.
The actual pages that you need to rank well in Google.
And quite often, the pages that you need to rank well are also the hardest ones to get links to. That’s because people generally prefer to link to informational pages where their audience can get value for free rather than commercial pages where their audience is likely to part ways with their cash.
Thus, one of the most common questions in SEO is this: “How to get links to boring pages?”
And while there’s no single right answer to this question, everyone agrees that you should leverage the power of internal linking to help your “boring pages” rank better.
Best link building strategies
In part two, I listed a few dozen link building tactics and strategies for you to explore. But which of them are the best and most effective ones?
Here at Ahrefs, we’re big advocates of the following four:
Pursuing competitors’ links
Creating linkable assets
1. Pursuing competitors’ links
Competitor link research is one of the most fundamental activities in link building. Think about it. The top-ranking page for your desired search query has all the right links, which persuaded Google of its superiority. Therefore, by studying its links, you can figure out which tactics to use so that you can get similar links and outrank that page.
And this is where an SEO tool like Ahrefs is absolutely indispensable.
Just put the keyword that you want to rank for in Ahrefs’ Keywords Explorer and scroll down to the “SERP overview.” It will show you how many backlinks (and linking websites) each of the top-ranking pages has:
Click on any of these numbers, and you’ll see a report listing all of the links.
From here, your course of action is twofold:
Try to get links from the pages that link to your competitors
Study how those links were acquired and use the same tactics to get more links than your competitors
2. Creating linkable assets
In SEO, we use the terms “linkable asset” or “linkbait” to refer to content that is strategically crafted to attract links. Such linkable assets can take on many different forms:
Online tools and calculators
Infographics, GIFographics, and “Map-o-graphics”
Awards and rankings
Studies and research
How-to guides and tutorials
Definitions and coined terms
I’m sure that even in the most boring industries there’s a way to create an interesting piece of content that will attract links. So it’s always a good idea to study the websites of your competitors and see if they have any linkable assets that you could get inspiration from.
To do that, simply put their domain name in Ahrefs’ Site Explorer and go to the Best by links report. This will show you which of their pages have accrued the most links.
As you can see in the screenshot above, three of the five most linked pages on the Ahrefs Blog (excluding the homepage) are data-driven research studies. That gives you a pretty good idea of the kind of content that attracts links in our industry.
3. Content promotion
No matter how “linkable” your pages are, people can’t link to them without first discovering them. In other words, even the best linkable assets have to be promoted in order to attract links.
“Who will amplify this? And why?” According to Rand Fishkin, the answer to this question determines the amount of exposure that your piece of content is destined to get.
“Who” refers to influential people and relevant communities in your space that might help to put your content in front of large numbers of people. And “why” refers to the actual merit of your content that makes it worthy of being promoted in the first place.
Fun fact. Back in 2015, I reached out to Rand, asking him to tweet my article. And his response was essentially a crash course in how this works:
You can easily bring lots of visitors to your content with the help of advertising on platforms like Facebook, Google, Twitter, and the like. Alternatively, you can partner with selected influencers and content creators in your space and pay them to promote your content to their audience.
Some people, though, find it hard to justify spending money to promote their content. Which naturally begs the question: How did they justify spending time to create it in the first place?
If you create your content with your business goals in mind, you should not have issues to justify spending money to promote it to people.
3. Growing an audience
Each time you publish and promote a piece of content, you’ll reach some people who will find value in it (or simply enjoy it). And it would be a real shame to part ways with these people and never be able to reach them again, wouldn’t it?
That’s why you have to work on growing your audience. Which can be done in a few different ways:
Ask them to subscribe to your email list
Ask them to follow you on Twitter/LinkedIn/Instagram/TikTok
Invite them to join your private community on Slack/Discord/Facebook
Retarget them with Facebook/Twitter/Google ads
With every new cool piece of content that you release, your audience should be getting larger and larger. And the more people follow your work, the less you’ll need to bother about promoting your content manually.
As discussed earlier, asking for links without offering anything of value in return barely even works these days. But guest posting is not like that. You’re offering a quality piece of content in exchange for an opportunity to link to your website from it. That sounds like a fair exchange of value.
Here at Ahrefs Blog, we have a “write for us” page, inviting our readers to contribute a guest article for us. And yet, we reject the vast majority of pitches we receive. Our standards for guest contributions are very high.
So here are two simple tips that will help you get published in the top blogs of your industry:
1. Start small and work your way up
It is much easier to get the attention of the top blogs in your niche when you have a solid portfolio of published content on slightly smaller blogs.
So before you pitch a guest article to the owner of a DR80+ blog, make sure you have a published DR70+ piece to show them. And before you pitch that DR70+ blog… well, I’m sure you get the idea.
You can use Content Explorer to quickly find relevant blogs of required “authority.” Just search for a related word or phrase in page titles and use the “Domain Rating (DR)” filter to narrow down results:
2. Make an irresistible offer
What do blog owners want? They want to grow traffic to their blog.
So if you can persuade them that your guest article will rank well in Google for its target keyword and bring them consistent search traffic, it will be an easy sell.
And that’s where the previous tip is absolutely invaluable. If you can show some actual examples of your past guest articles that rank well, I bet you’ll get the deal easily.
A somewhat lesser-known guest posting tactic is to find an underperforming article on their blog (in terms of search traffic) and offer to do a complete overhaul with the goal of improving its Google rankings. In many cases, the blogger will be happy for you to do that.
Just open the Top pages report in Site Explorer and use the “Traffic” filter to find underperforming articles easily:
Link building tools
While it is technically possible to build links with just a bit of brain power and a Gmail account, there are a number of link building tools that will help make the process of acquiring links much easier.
Here are some free ones:
Ahrefs Webmaster Tools – Shows all links pointing at your own website already and lets you sort and filter them by many important SEO metrics.
Google Alerts – Notifies you whenever a specific word or phrase was mentioned on a newly published page. Which is a great way to source quality link prospects.
And here are some premium ones:
Ahrefs’ Site Explorer – Shows you all links of any website or URL with an option to sort and filter them by many important SEO metrics.
Ahrefs’ Content Explorer – A unique link prospecting tool, which helps you find thousands of relevant websites for link requests and guest posting. Also helps to research linkable assets on any topic from all around the web.
Ahrefs Alerts – Similar to Google Alerts but designed specifically with SEO professionals in mind.
Pitchbox/BuzzStream/GMass – Email outreach tools. There are many other tools that let you send personalized emails at scale, but these ones are the most popular among SEOs.
Hunter.io/Voila Norbert– The so-called “email lookup services,” which help you find contact details of websites at scale.
