Link building has a bad reputation in some circles because a lot of what gets called link building is actually link spam. Learning to build links well means learning to distinguish between the two — and being honest about the fact that the line between them has moved over time.

Why Links Still Matter

Links remain one of the most significant ranking signals in search. A page with strong content but no links consistently underperforms a page with comparable content and meaningful external link equity. This is not a secret, and it is not going away. What has changed is which links count, which get discounted, and which actively hurt.

Google has gotten substantially better at identifying and discounting links from low-quality or irrelevant sources. Links from sites that exist primarily to pass link equity — private blog networks, link farms, mass directory submissions — are neutralized at best and penalized at worst. The links that still work are the ones that would exist even if Google had never invented PageRank: genuine editorial mentions from relevant sites.

The Foundation: Something Worth Linking To

Most link building problems are actually content problems. If you have no pages on your site that a reasonable person would voluntarily link to, no outreach strategy will work at scale. The foundation of durable link building is having something genuinely useful — original research, a tool, a definitive guide to something specific, a dataset, a perspective on something that others in the space have gotten wrong.

This is not glamorous advice, but it is accurate. The sites I have watched build durable link profiles over years are the ones that published things worth linking to and then promoted those things to the people likely to care.

Tactics That Hold Up Over Time

Digital PR and Content Promotion

Creating something newsworthy or useful in your niche and then actively promoting it to journalists, bloggers, and podcast hosts who cover that space. This takes more work than link outreach templates, but the links are better and they do not disappear when the tactic gets devalued.

Resource and Partnership Links

Identifying where your content genuinely belongs — as a resource on a partner site, in a community wiki, in a further reading section of a relevant publication — and reaching out to suggest the addition. The key word is genuinely. If you have to stretch to make the relevance argument, you are already in gray-area territory.

Podcast and Speaking Appearances

I co-host the SEOST / SEO Spring Training conference in Chandler, Arizona alongside Clint Butler. Events like this generate natural editorial links — coverage, recaps, speaker profiles. Speaking at industry events and appearing on podcasts generates the kind of authority links that are essentially impossible to replicate with outreach tactics.

Unlinked Brand Mentions

If your brand or site is mentioned somewhere without a link, converting those mentions into links is lower-effort than cold outreach and produces high-relevance results. Tools that track brand mentions make this findable at scale.

What to Avoid

  • Reciprocal link exchanges at scale — I link to you, you link to me is obvious enough that it gets discounted
  • Guest posting on sites with no real audience, purely for the link
  • Paid links that are not disclosed — this is a violation of Google guidelines and the risk/reward is poor
  • Links from sites in completely unrelated niches

How to Audit Your Link Profile Before Building More

Before running any outreach campaign, it is worth understanding what you already have. Ahrefs and Semrush both give you a reasonably complete picture of your referring domain count, the distribution of link authority across your pages, and which pages are receiving the most equity. Google Search Console shows you links Google has credited — which is different from what a third-party tool sees and is often more conservative.

What you are looking for in an audit: are your best links pointing to your most important pages, or are they pointing to legacy content that no longer converts? Are you earning links across the whole site or are they concentrated on one or two assets? Are there referring domains with very low quality scores that might dilute the profile? A disavow is rarely necessary and often counterproductive — but knowing what is in the profile helps you understand what you are working with.

I run this kind of audit as a starting point at Salterra before recommending any link acquisition strategy. Building on top of an unmapped profile is working blind.

What Healthy Link Velocity Looks Like

Link velocity — the rate at which new referring domains point to your site — matters because sudden spikes are a signal Google uses to identify manipulation. A site that goes from five referring domains to five hundred in thirty days is going to attract scrutiny, even if the links are legitimate. Organic link growth tends to look like a gradual curve, occasionally punctuated by a spike when a specific piece of content hits or a publication runs a story.

For most small to mid-size sites, earning three to eight new referring domains per month from relevant, quality sources is a genuinely strong profile. Chasing volume beyond what your content naturally merits is where the risk/reward starts shifting. Focus on rate of quality, not rate of quantity.

Building a Repeatable Outreach Process

If you are going to do manual outreach — identifying relevant sites, finding the right contact, and pitching a link — it helps to build a process rather than treating each outreach as a one-off. The realistic response rate for cold link outreach is one to five percent. That is not a failure rate; that is the baseline. If you send a hundred personalized, well-researched pitches and get three or four responses that convert, that is a functioning process.

The elements of a process that actually works: a clear reason the link benefits the site you are pitching (not just you), a specific page you are suggesting they link to or link from, a contact person rather than a generic form, and a short message. Long pitches get skimmed and deleted. The outreach that works is usually under a hundred words.

When Link Building Is Not the Bottleneck

This is the honest counter-case, and it is worth saying plainly: if your technical foundation is broken or your content is thin, chasing links is wasted effort. I have seen sites with strong link profiles that could not rank because crawl issues were blocking important pages from being indexed. I have seen pages with dozens of referring domains that ranked poorly because the content did not actually answer the query well enough.

Links amplify what is already there. They do not compensate for structural problems. Before investing heavily in link acquisition, verify that your pages can actually be crawled and indexed, that your content is genuinely useful and complete, and that your internal linking is passing authority where it needs to go. The advanced SEO training section covers the technical and structural foundations that need to be right before link equity can do its job.

Link Building as Part of a Broader Strategy

Link building works alongside everything else — it amplifies good content and correct technical foundations. A strong link to a page with technical problems or thin content produces less value than the same link to a well-constructed, fast, properly structured page.

The SEO training work I do treats link building as one component of a complete strategy rather than a separate discipline. For the content side that supports link earning, content SEO covers how to build the kinds of pages and resources that attract links naturally over time. You can also reach out to Salterra if you want to audit your current link profile and identify the highest-value opportunities.
