If your company has ever paid for a flat-rate package of 50 backlinks, there is a good chance some of them sit on a portal no real reader ever opens. Search engines spot that pattern, and so do AI models.
In this guide you will learn how to separate what still builds authority from what has become a liability in your link profile.
What Link Building Is
Link building is the work of earning links from other websites pointing to yours, in a way that Google and AIs interpret each citation as a vote of confidence. In 2026 the game shifted from volume to context: what matters is who links, in which article, with what anchor, and to which page. Ten editorial links on real portals move more authority than a hundred links planted across blog networks.
The logic has been around since PageRank, in 1998. A link is a public recommendation: when a respected outlet cites your company as a source, it lends part of its credibility to your domain. Google has been measuring this for over 25 years and still is.
What changed was the arrival of a second audience: generative AIs.
ChatGPT, Gemini, Perplexity, and Claude decide which brands to cite in their answers by cross-referencing similar signals. Brands that appear frequently in trustworthy content, with mentions in editorial context, tend to become sources in the answer. Brands that only exist on their own website get left out. The backlink is no longer an exclusive ranking signal and has become the foundation of a domain's digital authority, read by search engine and language model at the same time.
That is why the keyword here is editorial context. A link inside a real article, written for a real audience, on a portal with traffic and history, transfers authority. A link stuffed into a footer, a generic directory, or a site created solely to sell links transfers risk, and the next sections show exactly where that line falls.
If you have already received a proposal for a "package with 50 backlinks per month," it is worth paying attention to the rest of this guide. A low unit price is usually the first symptom of a link no human will ever read.
What Still Works for Earning Backlinks
The criterion comes before the tactic: a good link comes from a page with real traffic, inside a text about your topic, positioned within the body of the content. A link in a footer or on a page nobody visits passes along almost nothing.
Press Relations and Proprietary Data
Journalists link to sources, not ads. Publish a data point only your operation has (a customer survey, a market figure, an internal study) and offer it to outlets in your industry. This is the work Netlinks runs through its digital authority practice, with Atomico Press. Realistic timeline: 60 to 90 days for the first citations.
Reference Content That Attracts Links on Its Own
Glossaries, calculators, annual benchmarks. Anyone writing about the topic needs to cite someone, and they cite whoever has the best page. It works slowly (6 to 12 months), but the links arrive with no negotiation and in perfect context.
Partnerships, Editorial Guest Posts, and Co-Creation
Guest posting still works when the portal has its own audience and an editor who rejects weak copy. Simple test: would the site publish your article even without the link? If the answer is no, you are buying media, not earning a citation. Webinars and joint studies with complementary companies generate links on both sides.
Mentions in Directories, Associations, and Niche Profiles
Industry associations, category directories, supplier partner pages. Low volume, zero glamour, but these are the citations AIs like ChatGPT and Perplexity use to confirm the company exists and operates where it claims to.
What Became a Risk and Can Sink Your Site
Since the link spam updates, Google has been neutralizing artificial links at scale with SpamBrain. In practice, the wrong purchased link stops counting, and the entire profile can be devalued along with it. If your traffic dropped and nobody can explain why, start with this list.
PBNs and Blog Networks Built Only to Link
Sites with no real audience, the same template, generic articles about any subject. Red flag: the agency report lists domains you have never heard of that show no traffic in any tool.
Bulk Link Buying and Marketplaces
Platforms that sell links by the unit place your brand next to casinos, betting, and shady lending, on the same portals, with the same footprint. The algorithm recognizes the pattern because thousands of sites buy from the same place.
Reciprocal Exchanges at Scale
One partner link is normal. Fifty domains linking to each other in rotation form a network shape no organic profile ever produces.
Automated Guest Posts with AI-Generated Text
Shallow articles produced in batches, published on blogs that accept any paid pitch. Google classifies it as content spam, and AIs will not cite a page that answers nothing.
Repeated Exact-Match Anchors and Off-the-Curve Growth
A healthy profile mixes brand anchors, URLs, and generic terms. If 40% of your backlinks use the same commercial keyword, it was manufactured. The same goes for jumping from 10 to 300 domains in two months.
Recognized two or more of these signals? The problem has a name, and it can be reversed.
How to Audit Your Backlink Profile
Export the full list of domains pointing to your site. Search Console already gives you Google's view; Ahrefs or Semrush fill in the gaps with estimated traffic and anchors. One afternoon is enough.
With the list in hand, evaluate four points per domain: the site covers your topic, the linking page gets visits, the anchor sounds natural, and the acquisition pace tracks the brand's real growth. Thirty commercial links appearing in the same month, on a dormant site, is a pattern SpamBrain recognizes.
Metrics That Matter and Vanity Metrics
DR and DA alone are misleading: there are domains with DR 70 and zero visitors. Prioritize the domain's organic traffic, the traffic of the specific linking page, and the position of the link within the body of the text. Those three say more than any aggregate score.
When to Use Disavow and When to Leave It Alone
A weak link (a small but real site in your industry) can stay put; Google already ignores what has no value. Disavow applies in two scenarios: a large-scale negative SEO attack or a history of buying from blog networks that you want to shut down. Beyond that, touching the file usually causes more damage than the original problem.
Finished the audit and decided to outsource? Demand three things from whoever executes: a list of portals approved by you before publishing, proven traffic for each outlet, and a report with the URL of every live link. A serious link building agency shows you this without you having to ask twice.
Where to Start in the Next 30 Days
If your traffic has stalled while content ships every week, now you know where to look: the problem usually lives in the backlink profile, invisible in editorial reports and ignored by most of the agencies you have already hired.
Three things to take from this guide:
- Context outweighs volume. Ten editorial links on portals with real audiences move more authority than a hundred placements on ghost sites. Google and AIs read who cites you, in which article, and with what anchor.
- The wrong purchased link is now a liability. Since SpamBrain, artificial links stop counting and can drag the entire profile down with them. Auditing before building is no longer optional.
- A natural pace protects the result. Acquisition in suspicious spikes attracts the wrong filter's attention. Monthly consistency in outlets covering your topic is what sustains position.
The first move fits into one afternoon: export the domains from Search Console, classify the top 20 against the four audit criteria (topic, traffic, anchor, pace), and separate what builds from what contaminates. With that map, deciding whether to clean up, hold steady, or accelerate becomes objective.
After that, the game becomes presence: proprietary data, digital PR, and press citations that feed the brand's ongoing authority work, the same signal ChatGPT, Gemini, and Perplexity use to decide who to cite.
Authority is not bought in bulk; it is built one citation at a time.

Frequently Asked Questions
How much does link building cost?
As a market benchmark, an editorial placement on a relevant Brazilian portal typically ranges from a few hundred to a few thousand reais, depending on the outlet's traffic and authority. Ongoing agency projects start at four-figure monthly retainers. The real cost, however, is measured per usable link: paying little for dozens of links on sites with no audience ends up far more expensive when Google neutralizes them all.
How many backlinks do I need to rank?
It depends on what your keyword's competitors already have. Export the domains pointing to the three pages at the top and compare them with yours. In Brazilian B2B niches, the gap is usually dozens of domains, not thousands. Ten editorial links on portals covering your topic move more than a hundred generic placements, so count relevant domains, not total links.
How long does link building take to produce results?
Google needs to crawl the link, reassess the page, and reprocess the ranking, which usually takes 3 to 6 months for a visible effect on positions. Links on pages with real traffic speed up that cycle because they are crawled more often. Anyone promising a jump in positions within weeks is selling a site network, and that shortcut appears on the risk list in this link building guide.
What is the difference between link building and digital PR?
Link building is the complete discipline of earning links: guest posts, mentions, recovering unlinked citations, content partnerships. Digital PR is one branch of that discipline, focused on the press: you offer data, research, or a spokesperson and the journalist cites the source in the body of the story. PR tends to generate the links that are hardest to replicate, because no competitor can buy space in editorial coverage.
Can buying backlinks sink my site?
It can devalue your entire profile. Since the spam updates, SpamBrain identifies artificial link patterns at scale and neutralizes them. In the common scenario, the wrong purchased link simply stops counting, and the money evaporates. In the worst scenario, the site receives a manual action and loses positions across the board. The risk lies in the type of site doing the selling: no audience, same template, generic content.
Are nofollow links good for anything?
They are. Nofollow does not transfer direct authority, but it generates referral traffic, real clicks, and brand mention in context. Generative AIs read the citation, not the link attribute: for ChatGPT or Perplexity, being cited in a story on a major portal carries weight even with nofollow. A healthy profile mixes both types, because a 100% dofollow profile looks manufactured.
How do I know if my backlinks are good or bad?
Export the domain list from Search Console and supplement it with Ahrefs or Semrush. Evaluate four points per domain: the site covers your topic, the linking page gets visits, the anchor sounds natural, and the acquisition pace has no strange spikes. A domain that fails three of the four criteria is a candidate for monitoring or disavow. One afternoon of work handles the first audit.
