Ask five people what a backlink is worth and you'll get five different numbers, usually because the question is being asked about the wrong thing. A link's value isn't a fixed price — it depends entirely on what's linking, why, and whether the link would exist if nobody had paid for it. Most of the confusion around link building comes from skipping that last question.
What a genuinely earned link actually signals
A link that exists because a real site, read by real people relevant to your business, chose to reference you is a signal that something about your business was worth mentioning. That's the entire logic behind why search engines treat links as a ranking factor in the first place — they're a rough proxy for "other people vouch for this." A link from a site with genuine readership, topical relevance to your industry, and no financial relationship to you carries that signal intact.
Why bought links usually underperform their invoice
A link bought specifically to manipulate rankings breaks the logic at its source: it doesn't exist because anyone chose to reference you, it exists because you paid for placement on a site that may have no real readership, no topical relevance, and no reason to exist beyond selling links to businesses like yours. Search engines have spent years getting better at recognising these patterns — networks of thin sites cross-linking, sudden bursts of low-quality links, link placements with no editorial context around them. The realistic outcomes range from the link simply carrying no ranking value, to the source site itself carrying so little authority that the link is worthless by association, to — in the worse cases — the pattern drawing scrutiny that costs more than the link ever contributed. Paying for a hundred links that fall into this category is rarely the same as earning ten that don't.
What actually predicts whether a link helps
Before paying for anything described as link building, a few questions separate genuine value from a wasted invoice: does the linking site have real visitors who aren't other businesses buying links from the same network, is the content around the link genuinely relevant to what it's linking to, would a person actually click that link and land somewhere useful, and is the placement something an editor chose or something a spreadsheet assigned. A link that fails most of these is close to worthless regardless of what a vendor's metrics dashboard claims about its authority score.
What to do instead
The most reliable path to links worth having is being the kind of business, or publishing the kind of content, that other sites reference because it's actually useful to their readers — a guide, a genuinely original piece of research, a resource other businesses in the same space would credit rather than avoid. This is slower than buying a package of links, and it's also the only version that survives search engines getting better at telling the difference, which they reliably do. It's part of why our marketing team treats link building as a byproduct of content and reputation work rather than a line item bought in bulk — a distinction that sits inside the broader discipline covered in our SEO strategy framework.
