# Backlink: what is an inbound link and which ones count?

> A backlink is a link from another site to yours. What Google counts, which links break its spam policies, how sponsored and ugc work, plus an example.

Updated on October 15, 2026 · https://app.pilotiko.com/en/glossary/backlink

A backlink, or inbound link, is a link on another website that points to a page on your site. Search engines use backlinks to discover pages and as one sign of how well known a business is. Google's spam policies forbid links bought or built to manipulate rankings.

## In short
- A link from another site to yours, as opposed to internal links.
- For local results, Google lists how many websites link to a business among the signs of prominence.
- Buying or selling links for ranking breaks Google's spam policies.
- Paid links get rel=sponsored; user-generated ones get rel=ugc.

## Why do backlinks matter?

A link from another site does two jobs. First it is a path: Google discovers pages by following links from pages it already knows [5]. Second it works as an implicit vote of confidence.

For local results, Google says a business's prominence depends partly on how many websites link to it and how many reviews it has [3]. That is a big reason backlinks matter to service businesses investing in [local SEO](https://app.pilotiko.com/en/glossary/local-seo).

A backlink is different from [internal linking](https://app.pilotiko.com/en/glossary/internal-linking), which connects pages on your own site. You control internal links; you have to earn backlinks.

## Which links does Google treat as spam?

Google's spam policies describe links created to manipulate rankings [1]. The examples are specific:

- buying or selling links for ranking purposes;
- excessive link exchanges (link to me and I'll link to you) or partner pages built only to cross-link;
- using automated programs or services to create links;
- requiring a link in terms of service or a contract without letting the site owner qualify it;
- low-quality directory or bookmark site links;
- links with optimized anchor text in articles, guest posts or press releases.

## What do sponsored, ugc and nofollow mean?

| Value | When to use it | Small business example |
|---|---|---|
| rel=sponsored | Ads or paid placements | Sponsoring a minor hockey tournament that links to your site |
| rel=ugc | Links in user-generated content | Blog comments and forum posts |
| rel=nofollow | When other values don't apply and you'd rather not be associated with the linked page | Linking to a source you have doubts about |

nofollow is still acceptable for paid links, but sponsored is preferred [2]. Google advises against adding nofollow to every outbound link, only to sources you don't trust [4].

## Which links can a small business earn honestly?

**Example: link opportunities for a kitchen renovation company in Saskatoon**

A realistic list of sites that could mention the company with a link. The counts are hypothetical.

- Trade associations the company belongs to : 2
- Suppliers that list their installers : 4
- Local media that covered a project or initiative : 1
- Sponsored community groups (link marked sponsored by the publishing site) : 3
- Relevant sites to reach out to : 10
- **= Ten links that reflect real business relationships beat a bundle of 200 low-quality directory links, which Google's policies class as link spam.**

## Are backlinks all there is to SEO?

No. Google states there is no way to request or pay for a better local ranking [3]. A link will not make up for a vague page or a half-finished business profile. Trust is built with useful, verifiable content, which is what [E-E-A-T](https://app.pilotiko.com/en/glossary/e-e-a-t) is about, and with solid [search engine optimization](https://app.pilotiko.com/en/glossary/seo) on your own site.

## Which backlink mistakes should you avoid?

- Answering the email that offers 100 high-authority links for a few dollars.
- Swapping links with every supplier on a partners page built just for that.
- Writing a mandatory link to your site into subcontractor agreements.
- Repeating the same keyword-stuffed anchor in every press release.
- Judging a link by a third-party tool score instead of its relevance to your customers.

## Does Pilotiko build backlinks?

No. Building or buying links is not a Pilotiko feature. What is available: a business website built and hosted for you, with a sitemap, [structured data](https://app.pilotiko.com/en/glossary/structured-data) and an [llms.txt](https://app.pilotiko.com/en/glossary/llms-txt) file, an audit of your current site and content drafting that waits for your approval. Useful content remains the honest way to earn links.

## Frequently asked questions

### Is a backlink the same as an inbound link?

Yes. Backlink, inbound link and incoming link all describe a link from another website to yours.

### Is buying backlinks illegal?

It is a matter of Google's rules rather than the law: buying or selling links for ranking is listed as link spam. A paid link should be marked rel=sponsored or nofollow.

### Is a sponsorship link a bad backlink?

Not if it is qualified properly. Sponsorship is legitimate; the publishing site should simply mark the link rel=sponsored.

### Do social media links count?

They can bring visitors. Links posted by users are the kind Google recommends marking ugc, so do not count on them to build search engine prominence.

### How many backlinks does a small business need?

There is no official number. A handful of relevant links from sites tied to your trade or region is worth more than a pile of unrelated ones.

### What if I already bought links?

Stop buying them and, where possible, ask for removal or for the links to be marked sponsored. Then put the effort into your content and local relationships.
