Link Building: Sort Every Tactic by What the Other Person Gets
Every link is a transaction. The tactic you pick matters far less than what the person on the other end receives for saying yes.
Link building is the practice of getting other websites to link to yours, because Google treats a link as one site vouching for another. That much is agreed. What is not agreed is how to organise the work, and almost everyone organises it wrong.
Open any major guide to link building and you get a list of tactics. Guest posting. Broken link building. Digital PR. Resource pages. HARO. Skyscraper. Fifteen numbered sections, each with a how-to, each presented as an interchangeable option you might pick up depending on your mood and budget.
That structure is the reason those guides are indistinguishable from each other, and it is the reason most link building programmes stall. A list of tactics tells you what you could do. It does not tell you which one will work for you, and it hides the variable that decides.
Here is the variable. Every link is a transaction. Somebody with their own site, their own readers and their own reasons has to take an action that benefits you. The question that predicts whether they will is not which tactic you used. It is: what do they get?
Sort link building by what the other person receives and the whole field collapses into four transaction types. They have wildly different costs, different success rates, and different rules. Most failure is running one type at another type's price.
Link building exists because almost no page earns links on its own#
Before the taxonomy, the reason any of this is worth doing.
Ahrefs took the whole database from their Content Explorer tool, around 14 billion pages, and checked how much organic search traffic each page gets. Their finding: "96.55% of all pages in our index get zero traffic from Google, and 1.94% get between one and ten monthly visits."
The second number in that study is the one that should change how you budget. Ahrefs write: "Our index contains ~20 million pages with no referring domains, yet only 2,997 of them get more than 1K search visits per month. That's roughly 1 in every 6,671 pages with no backlinks."
Read that as a conditional probability and it stops being a fun statistic. If your page has no referring domains, the odds of it doing meaningful traffic are about one in six and a half thousand. Publishing more pages does not change that rate. It just gives you more entries in the same lottery.
So link building is not the optional growth layer that sits on top of content. For most pages it is the qualifying round. Which makes it worth being precise about how it actually works.
The four reasons anyone gives you a backlink#
Strip away the tactic names and every link anyone has ever placed falls into one of four transactions, defined by what the publisher walks away with.
The quadrants are not ranked by quality. They are ranked by what they cost you and what they demand of the other side. Work through them in order.
Link building by fixing something broken is the easiest ask in the category#
In quadrant one you arrive with a problem already solved. Their page links to something that no longer exists. You point it out and offer a replacement.
The reason this converts better than a cold pitch is not that the email is cleverer. It is that you have inverted the favour. Ordinarily you are asking an editor to spend five minutes of their day improving your search rankings. Here you are telling them their published work is quietly broken, which is a thing they actually care about independent of you.
This is the entire mechanism behind broken link building, and it is also why resource-page outreach works when it is done with judgement and fails when it is done as a template. A curated list of tools is a page whose whole value proposition is completeness. Pointing out a genuine gap in it is a contribution. Pointing out that you are also a tool is not.
Two things keep this quadrant honest:
- The replacement has to actually replace. If the dead link pointed at a statistics page and you offer a product page, you have not fixed anything, you have asked for a favour while pretending to do one. Editors can tell.
- You need volume of candidates, not volume of emails. The finding is the work. Most people flip this and send more emails against a thinner list, which is how the tactic got its reputation for low reply rates.
Link building by supplying data is expensive, durable, and mostly misunderstood#
Quadrant two is where you give somebody material they could not have produced. Original research. A dataset. A genuinely expert opinion on a story that is running today.
This is the quadrant with the best economics over time, because one asset can be cited for years by people you never contacted. It is also the quadrant most often faked. A "study" assembled from other people's published figures is not new material, and journalists can spot recycled secondary data instantly, because reading press releases is their job.
The other common error is treating quadrant two as a creativity problem. It is mostly a relevance problem: the most original dataset in the world lands nowhere if it is sent to people who do not cover that beat. We went through the routing side of this in detail in digital PR link building.
If you have something real to give, this quadrant compounds. If you do not, no amount of outreach volume will manufacture it, and a campaign that pretends otherwise is just quadrant four with extra steps.
Link reclamation is link building where the persuasion is already finished#
Quadrant three is the strange one, because in most of it there is no other person at all.
Somebody already decided you were worth referencing. Then the link broke, or the page moved, or your name got printed with no anchor on it. The judgement call that quadrants one, two and four are all trying to manufacture has already been made, in your favour, and something mechanical went wrong afterwards.
Two of the four reclamation types need no outreach whatsoever, because the broken thing is on your own server. That makes link reclamation the highest-yield work available to most sites and also the most consistently skipped, because it does not look like a campaign and does not fit in a quarterly plan. Before you commission anything in quadrant two, run a backlink audit and find out how much of what you already own is currently leaking away.
Traded links are legitimate link building only when they are disclosed#
Quadrant four is where money or content changes hands, and it is the only quadrant with a rulebook, so it is worth quoting the rulebook precisely rather than repeating the folklore about it.
Google's spam policies define the offence as follows: "Link spam is the practice of creating links to or from a site primarily for the purpose of manipulating search rankings." The listed examples include "Exchanging money for links, or posts that contain links", "Exchanging goods or services for links", and "Advertorials or native advertising where payment is received for articles that include links that pass ranking credit, or links with optimized anchor text in articles, guest posts, or press releases distributed on other sites."
Note what the policy does not say. It does not say paid placement is forbidden. The same page states: "Google does understand that buying and selling links is a normal part of the economy of the web for advertising and sponsorship purposes. It's not a violation of our policies to have such links as long as they are qualified with a rel="nofollow" or rel="sponsored" attribute value to the tag."
So the line is not commerce. The line is undisclosed commerce that passes ranking credit. Google's documentation on qualifying outbound links is specific about which attribute to use: rel="sponsored" is for links that "are advertisements or paid placements (commonly called paid links)", and although "The nofollow attribute was previously recommended for these types of links and is still an acceptable way to flag them", Google says "sponsored is preferred".
Which reframes the whole guest posting debate. A guest post written because you have something to say to that audience is quadrant two wearing a different hat. A guest post bought at volume with your keyword in the anchor is the exact pattern the policy names. The tactic is identical; the transaction is not. The distinction, and what it means for how you write the byline pitch, is the subject of guest posting for backlinks.
One related point that belongs here: a qualified link is not a worthless link. Google's wording on nofollowed links is that they will generally not be followed, not that they are ignored by everything. Referral traffic, audience and the relationship are unaffected by an attribute. We unpacked that in dofollow vs nofollow links.
Link building is a routing problem before it is a persuasion problem#
Here is what the quadrant model exposes that a tactic list hides. In three of the four quadrants, the expensive step is identical, and it is not writing.
This is why the industry's productivity story has been wrong for a decade. The tooling got very good at step five. Sequencers, mail merge, warmup, deliverability dashboards. Step five was never the constraint.
The largest outreach dataset anyone has published says the same thing from the other direction. Backlinko and Pitchbox analysed 12 million outreach emails and found that "only 8.5% of outreach emails receive a response." More usefully, they measured what raised that number.
Read down that list and none of it is craft. Reaching several people at a site instead of one is a research output. Following up is persistence. Personalising the body and the subject line are only possible if somebody has already worked out what that person publishes. Every lever in the largest outreach dataset available is downstream of the three research steps, which is why the same email template performs completely differently depending on the list it is sent to.
The constraint is that finding two hundred genuinely relevant sites, identifying the right person at each, and understanding what they cover well enough to say something true about it is slow, unglamorous research that a person has to sit down and do. Skip it and you get the thing everybody complains about receiving: a well-delivered, perfectly warmed, completely generic email. That research loop is what GenLink runs, which is the only reason it can hold personalisation and volume at the same time.
If you want the mechanics of that step specifically, link building prospecting covers the list-building side and link building outreach covers the message.
How to choose a link building strategy from the quadrant you can supply#
The practical use of the model is that it turns strategy into a supply question. Do not ask which tactic is best. Ask what you actually have to give, then read across.
| What you have | Quadrant | Tactic that fits | What it costs you | What it gets them |
|---|---|---|---|---|
| Time and a crawler | 1. You fixed it | Broken link building, resource pages | Research hours | A page that works again |
| Proprietary data or real expertise | 2. You supplied it | Digital PR, original studies, expert commentary | Real money, months | Material they cannot produce |
| An existing brand and old pages | 3. Already earned | Reclamation, unlinked mentions, redirect repair | Almost nothing | Nothing, it is your own plumbing |
| Budget and nothing else yet | 4. You traded | Sponsorships, paid placement | Cash, plus mandatory disclosure | Revenue |
| Nothing on this list | None | Build the asset first | Everything | Nothing yet |
The last row is the honest one. If you have no data, no expertise, no existing mentions and no budget, you do not have a link building problem. You have a nothing-to-link-to problem, and outreach will not fix it. This is the failure mode the tactic lists actively encourage, because a list of fifteen tactics implies at least one of them must be available to you.
Two more things worth getting right whichever quadrant you end up in.
Relevance beats authority more often than the metrics suggest. A link from a site that genuinely covers your subject is worth more than a higher-scored link from a general site that will never send you a reader. Domain scores are third-party approximations, not signals Google publishes, and optimising directly for them is how link profiles end up looking assembled rather than earned. The fundamentals are in what is a backlink.
Do not dictate anchor text. Suggesting a natural way to refer to your page is fine. Sending a required keyword string is the pattern the spam policy explicitly names, and it is also the fastest way to make a friendly editor feel like a vendor. Anchor text optimization goes through where the real line sits, and why the percentage ratio tables everybody quotes are guarding against a failure mode Google retired years ago.
The link building programme that survives contact with reality#
Put the pieces together and a workable programme looks less like a campaign and more like a standing operation.
Quadrant three runs continuously and in the background, because it is maintenance of an asset you own and there is no reason to batch it. Quadrant one runs continuously too, at whatever rate your research capacity allows, because the candidate list regenerates itself as the web rots. Quadrant two runs occasionally, when you genuinely have something, and gets a real budget when it does. Quadrant four runs only when you have decided you are buying advertising, and it gets disclosed properly, because the alternative is trading a durable asset for a temporary one.
What you will notice is that none of those four are "do a link building sprint in Q3". The tactic lists produce sprints because a list implies you pick one and execute it. The transaction model produces a system, because the four quadrants have different clocks.
And every one of them, except the half of quadrant three you fix on your own server, comes back to the same bottleneck: finding the right site, then the right person, then having something true to say to them. Everything else in link building is logistics. For a complete picture of what good looks like at the tactic level, how to get more backlinks is the practical companion to this page.

Frequently asked questions#
What is link building in SEO?
Link building is the practice of getting other websites to link to yours, because search engines treat an inbound link as one site vouching for another. It matters because links are strongly associated with whether a page gets any search traffic at all. Ahrefs found that of roughly 20 million pages in their index with no referring domains, only 2,997 get more than 1,000 search visits a month.
Is link building still worth it?
Yes, and the distribution data is the argument. Ahrefs studied around 14 billion pages and found that "96.55% of all pages in our index get zero traffic from Google, and 1.94% get between one and ten monthly visits." For the overwhelming majority of pages, links are not an optimisation applied to content that already works. They are closer to the entry requirement for getting traffic in the first place.
Are paid links against Google's guidelines?
Undisclosed ones that pass ranking credit are. Google's spam policies say link spam is "the practice of creating links to or from a site primarily for the purpose of manipulating search rankings," and list exchanging money for links as an example. The same page also states that buying and selling links "is a normal part of the economy of the web for advertising and sponsorship purposes" and is not a violation when the links carry a rel="nofollow" or rel="sponsored" attribute. The offence is the lack of disclosure, not the commerce.
What is the best link building strategy?
There is no single best one, because the right strategy depends on what you can supply. If you have research time, fixing broken links on other people's pages is the cheapest entry. If you have proprietary data or genuine expertise, digital PR compounds the hardest. If you already have brand mentions and old pages, reclamation gives the fastest return because the persuasion is already finished. If you have none of those, build the asset before you start any outreach.
How long does link building take to work?
Longer than the campaign calendar most teams use, which is part of why the tactic-list approach disappoints. Reclamation can move within days because the links already exist and only the plumbing is broken. Outreach-based quadrants run on the publisher's schedule, not yours, and then on Google's recrawl and reassessment after that. Treat it as a standing operation with a steady rate rather than a sprint with a finish line.
How many backlinks do I need to rank?
The question has no fixed answer and chasing a count is the wrong target. What matters is whether the linking sites genuinely cover your subject, because a relevant link from a smaller site routinely outperforms a higher-scored link from a site that will never send you a reader. Third-party authority scores are approximations built by SEO tools, not signals Google publishes, so optimising directly for them produces profiles that look assembled rather than earned.
Link building is four transactions, and three of them start with the same unglamorous research. Find the sites that genuinely cover your subject. Find the one person there who can say yes. Work out what they actually publish, so you can say something true about it. That is the part that does not scale by hand, and it is the part GenLink runs: it finds the relevant sites, finds the person, writes a pitch specific to what they publish, sends it from a warmed mailbox, follows up, and triages the replies so you only ever see the ones worth reading. You still choose the quadrant. The agent does the routing.
