Link building explained: how earned backlinks actually work
Link building is the work of earning links from other websites to yours. This guide covers what counts as a link worth having, the tactics that hold up over time, and how to prove a placement really exists.
What is link building?
Link building is the practice of earning links from other websites to pages on your own, by giving the person who owns that page a genuine reason to reference you. The link is the result, not the product.
Search engines use links to discover pages and to judge which sources other people rely on. AI search systems read the same open web, so the pages that get referenced by credible sites are also the pages those systems are more likely to encounter and summarise. Neither outcome can be guaranteed by any tool.
Which links are worth pursuing?
A useful link comes from a page a real audience reads, sits in context next to related writing, and would still be there if search engines disappeared tomorrow. Three questions filter most opportunities:
- Is the page topically related to what you actually do, closely enough that a reader would follow the link?
- Does the site publish for people, rather than existing to host outbound links?
- Would you be comfortable showing the placement to a client alongside the email that earned it?
The main link building tactics
| Tactic | What you offer | Main constraint |
|---|---|---|
| Resource page links | A page that belongs on a curated list of references | The list has to already exist and be maintained |
| Broken link replacement | A working replacement for a reference that now 404s | You need genuinely equivalent content |
| Guest contributions | An original article written for that publication's readers | Writing time, and editorial standards |
| Unlinked mentions | A link on a page that already names you | Limited to the mentions that exist |
| Digital PR | Original data, research, or a story a journalist can use | Requires something new to say |
| Link reclamation | A corrected URL for a link that broke or moved | Only recovers links you already earned |
How outreach works
Outreach is a short message to the person responsible for a specific page, explaining what you noticed on that page and what you can offer. It is specific by necessity: an editor can tell within one sentence whether you read their work. The message should name the page, say what is missing or outdated, propose the addition, and stop.
Volume is not the lever people expect it to be. A hundred relevant, well read pitches outperform thousands of generic ones, and they do not damage the sender reputation of the inbox you rely on.
How to verify a link went live
A reported link is only evidence when someone checked the page. Verification means fetching the live URL, confirming your destination link is present in the HTML, reading the anchor text and the rel attribute, and storing a dated screenshot of the placement in context. If the link is later removed, the record shows when it existed and when it went.
What to avoid
- Private blog networks and sites built to sell links.
- Reciprocal link exchanges arranged to pass ranking signals.
- Bulk directory submissions with no editorial review.
- Anyone guaranteeing a specific number of links, or a specific ranking.
Where LinkRobin fits
LinkRobin reads your site, finds pages that relate to it, scores each opportunity with a plain English reason, drafts the outreach for that specific page, sends from your own connected inbox once you approve, and verifies the placement afterwards. It does not buy links, and it does not send anything you have not read.
Frequently asked questions
What is a backlink?
A backlink is a link on another website that points to a page on yours. Search engines and AI search systems treat it as one signal that other people found your page worth referencing.
How long does link building take?
Editorial link building runs on other people's schedules. A pitch usually needs days or weeks before an editor replies, and a placement may appear later still, when the page is next updated. Anyone promising links on a fixed daily quota is usually buying them.
Are paid links against Google's guidelines?
Buying or exchanging links to pass ranking signals is a link scheme under Google's spam policies. Links you earn because an editor genuinely wanted to reference your page are not.
How do you know a link is real?
You fetch the live page, confirm the URL is present, read the anchor text and the rel attribute, and keep a dated screenshot. Anything reported without that check is a claim, not a link.
