Link Building That Still Works (and the Kind That Never Did)

Links still matter. Search engines have spent two decades getting better at ignoring the manufactured kind, but editorially given links from real publications remain one of the strongest signals a site can earn, and the brand mentions that come with them now feed AI answers too. Google's optimization guide is blunt about inauthentic mentions and magic schema for Overviews. The same instinct applies to bought links. A link that anyone can purchase is a link the ranking systems have every reason to discount, because it carries no information about whether the linking site vouches for you.

The problem is that "link building" describes both a legitimate discipline and a spam industry, and they're sold in the same marketplaces. The same proposal that promises "high DA placements" can mean a real editorial feature in a trade publication or a slot on a site that exists only to sell slots. Here's how we separate them.

The kind that never really worked

If a link can be bought by anyone with a credit card, it carries no signal. That's the entire logic of why links count in the first place. A link carries weight because a human editor chose to spend their reputation on your page. Remove the editor and the choice, and you've removed the thing the link was measuring. Into this bucket:

Guest-post farms. Sites that exist to sell placements, recognizable by their "write for us" pages, incoherent topic mix, and zero real readership. Google has been discounting these at scale for years. The tell is the topic spread: a single domain publishing about crypto, dental implants, and SaaS HR software in the same week is not a publication with an audience.
Private blog networks. Expired domains resurrected to link to clients. When they're caught, and detection keeps improving, the links evaporate at best. At worst the penalty follows the linked site, because the network footprint is the giveaway.
Mass directory and comment spam. Nobody's ranked off this in a decade; it survives purely because it's easy to invoice. A spreadsheet of 500 directory submissions looks like work on a status report and does nothing on the SERP.

The worst case isn't a penalty (though manual actions still happen). It's paying monthly for links that pass nothing, while your competitors invest in things that compound. You spend the same budget and end the year further behind, because they were building assets and you were buying noise.

The kind that works

Everything that works shares one trait: the linker gains something by linking. That's what "editorial" means. The linker is making their page better, more credible, or more useful by including your reference. When that incentive exists, the link is real.

Digital PR

Create something a journalist or blogger wants to reference, then tell the people who cover that beat. The reliable formats:

Original data. Survey your customers, analyze your own platform data, benchmark an industry practice. Data earns links for years because everyone who cites the finding needs a source. A finding is also hard to copy, which is why a good data piece keeps earning links long after the launch press fades.
Expert commentary. Reporters constantly need qualified quotes on news in your industry. Being fast and genuinely expert earns links from publications you could never buy into. The trade is your time and your knowledge, not your credit card.
Genuinely useful free tools. Calculators, checkers, templates. A tool that solves a real problem accumulates links passively long after launch, because every writer who explains the topic wants to point readers at something that does the work for them.

Unlinked mention reclamation

Search for your brand name, product names, and executives. Every mention without a link is a warm conversation: the author already chose to reference you. A polite request converts a meaningful share of these, and it's the cheapest real link building that exists. The author already did the hard part, which is deciding you were worth naming. Adding the link is a small ask in a conversation that's already open.

Being worth citing in comparisons

Roundups and "best X" articles in your niche get rewritten constantly. Make sure the writers doing it know you exist and can find accurate information about you easily. A good press page with real facts, pricing, and screenshots removes friction. These pages are also disproportionately what AI assistants synthesize when answering "what's the best X". A placement there works double duty: a link today, and a citation in a model's answer tomorrow.

What to expect from a real program

Honest expectations, because this is where agencies lose trust:

Editorial link building is slow. Campaigns take weeks to produce and outreach conversion is low even when it's working. A good month might be a handful of placements, not a flood.
Volume is lumpy. A data piece might earn dozens of links one month and none the next. That lumpiness is normal for earned coverage, and a flat monthly line is a sign of paid placement dressed up as earned.
You cannot fully control anchor text or target pages, and you shouldn't want to. Uniform, keyword-exact anchors are what a penalty profile looks like. Real link profiles are messy because real editors choose their own words.

If a vendor promises a fixed number of links per month at a fixed price with chosen anchors, you know which bucket you're in.

The AI-era bonus

One shift makes all of this matter more, not less: language models learn how to describe your brand from the corpus of text about it. Every earned article, quote, and comparison placement doesn't just pass link equity. It shapes what ChatGPT and Perplexity say about you. Manufactured links on fake blogs contribute nothing to that corpus. Real coverage does. The same earned mention that helps Search also teaches the assistants, which is why the work compounds across both surfaces now.

FAQ

Do guest-post farms still work?

No. If anyone with a credit card can buy the link, it carries no signal. Google has been discounting those placements at scale for years, and they do not teach assistants how to describe you.

Do links still matter for AI answers?

Editorially given links still help Search. The mentions that come with real coverage also feed how ChatGPT and Perplexity talk about you. That is the part a PBN never did.

What should we do instead of buying links?

Digital PR, original data, expert commentary, and reclaiming unlinked mentions. Slow, lumpy, and honest. We will not sell you a fixed quota of chosen anchors.
