Definition
A backlink is a link on another website pointing at a page on yours, giving a crawler a route to follow and a ranking system a signal to count. Unlike a brand mention, which names you in text without linking, a backlink carries both of those. In AI search the unlinked mention is no longer the poor relation.

At a glance
- A backlink comes from another domain. A link between two of your own pages is an internal link and counts differently.
- Two jobs sit inside one link: discovery, so a crawler finds the page, and endorsement, so a scoring system weighs it.
- The sentence wrapped around a link is retrievable text in its own right, which is why the wording often outranks the link.
- Link quality always beat link count, and the gap widened once models began reading the linking page rather than tallying it.
The link is the path, the sentence is the evidence
Two different systems look at the same link and take different things from it.
A crawler treats it as a route. It follows the href, finds your page, and adds it to the set of documents that can be retrieved later. That part has not changed.
A model treats the surrounding passage as content. When a trade publication writes that a brand supplies waterproof membranes to several well-known outdoor labels, that sentence is retrievable and attributable, and an assistant can use it without the reader ever clicking anything.
So one link produces two assets: a crawl path, and a claim about you written by somebody else. The second one gets quoted.
Counting links stopped being the scoreboard
The old question was how many referring domains you had. The better question now is which pages an assistant reads when someone asks about your category.
Those pages are often unglamorous. A Reddit thread comparing products. A supplier directory. A roundup on a niche trade site with modest traffic and a nofollow policy. An assistant reads that material and repeats what it says.
So a nofollow link on a page assistants retrieve can be worth more than a dofollow link on a page nothing reads. That inverts how most link-building programs are scored, and it explains why a strong domain authority number can sit next to almost no presence in AI answers.
Earn links from pages an assistant would read
- Find the pages already being cited in your category. Ask ChatGPT and Perplexity your buyers’ questions, note every source named, and treat that list as your target list.
- Check whether you are mentioned there at all. Directory entries, comparison roundups and community threads are often missing you rather than ranking you badly.
- Give a journalist something to cite. Original research is the only link asset that scales without outreach, because the number needs a source and the source is you.
- Write the pitch as a fact, not a request. Digital PR works when the sentence you want printed already exists in your material and only has to be copied.
- Stop reporting link volume on its own. Report which cited pages name you and which do not.
What a link gives you that a mention does not
| Backlink | Unlinked mention | |
|---|---|---|
| Crawl path | Yes | No |
| Classic ranking signal | Yes | Weak to none |
| Retrievable as text | Yes | Yes |
| Best at | Getting a page found and ranked | Getting a claim about you quoted |
| Usual way to earn it | Outreach, research, partnerships | Being the obvious example to name |
Frequently asked questions
-
Do backlinks still matter now that AI answers the question?
Backlinks still matter, with a narrower job. They get pages discovered and they carry weight in the search ranking that feeds a lot of AI retrieval. What they no longer do is decide who gets named in an answer, because a model scores the passage it retrieves rather than the domain behind it.
-
Is an unlinked mention as valuable as a backlink?
For AI visibility the two sit closer than they used to, because a model reads the sentence either way. For search they are not equivalent: a link passes signal a mention does not. Take both, and stop filing a mention as a failed link.
-
Should I buy backlinks?
No. Paid link networks target a ranking signal, and the pages they sit on are the low-value pages assistants skip. You pay for a metric while your citation footprint stays flat. The same money spent publishing something worth citing does both jobs.
-
How many backlinks does a page need?
There is no threshold worth quoting, and anyone naming one is guessing. Relevance and the quality of the linking page decide far more than volume. A handful of links from pages your buyers and their assistants actually read beats a long list from pages neither visits.
