Inbound link (backlink)
What is an inbound link (backlink)?
An inbound link, or backlink, is a hyperlink from someone else’s site to a page of yours. Search engines read it as a recommendation: a page many credible sources point to is treated as more reliable. Who links matters far more than how many — one link from a respected industry site outweighs a hundred from directories, and bought links earn a penalty rather than a position.
What makes a link valuable
- Relevance: a link from a site in your field or your town means more than one from an unrelated site.
- Trust in the source: a respected publication, an industry association, a university or a known partner, rather than a directory anyone can join.
- Context: a link inside an article that discusses your subject, with descriptive anchor text, counts more than one in a footer or a list of logos.
- Real readers: a link people actually click brings visits as well as a signal.
Links that are bought, swapped in bulk or placed by link networks break Google’s spam policies and can earn a penalty rather than a position.
Example
A small producer of honey has a good site but few visits from search. It does three things over a year. It publishes a guide to telling real honey from adulterated honey, with its own lab results, which two food blogs and a regional news site link to. It joins the national beekeepers’ association, which lists members with a link. And it supplies three delicatessens, which add “where to buy” links on their sites.
That is eleven new links in a year, all relevant. The site’s visits from search triple, and the guide ranks first for the question it answers. A package of 500 directory links, offered for €99, would have brought nothing or worse.
Why it matters for a business
Links remain one of the strongest signals search engines use to judge which pages to trust. A site with good content and no links often ranks below a weaker site that others recommend. But the signal works only because it is hard to fake, so the links worth having are the ones that are earned: through useful content, real partnerships, press coverage, sponsorships and membership in your field.
The useful work is often closer to public relations than to technical SEO: giving journalists, partners and associations a reason to mention you. See link building.
What to ask
- Which sites link to us today, and which of them are relevant to our field?
- What do we publish that someone else would want to cite?
- Which partners, suppliers, associations and local media could mention us, and have we asked?
- Has anyone ever bought links for our site, and do we know where they are?
Good backlinks are earned with useful content and real partnerships, not bought by the package. That is how we look for them in our SEO work.
