Backlinks: Links From Other Sites That Build Authority
A backlink is a link from another site to your page. Learn why links matter, what makes them strong, and how to earn them.
A backlink is a link from another website to your page, one of the strongest signals a search engine uses to judge authority.
What a Backlink Is
When another site links to your page, that link is a backlink. The search engine reads it as a vote, a sign that your page is worth citing.
Links have been part of ranking since the first search engines, and they still anchor the authority of a page.
Why Backlinks Matter
Search engines treat a link from a trusted site as evidence the page deserves attention. More strong links usually mean more authority.
Links also bring their own traffic. A reader on another site clicks through, and every referral is a visitor no ranking graph can measure.
Quality Over Quantity
A hundred links from random directories weigh less than one link from a respected site in your field.
Relevant sites, editorial placement, and descriptive anchor text all strengthen the vote. Spammy link farms weaken it and can pull the page down.
How to Earn Backlinks
- Publish original data or a resource others want to cite.
- Reach out to writers who cover the topic and offer a reason to link.
- Find broken links on related pages and suggest your page as a replacement.
- Build a page so complete that linking to it is the obvious choice.
The asset: a software site publishes a free calculator for project costs.
The outreach: the site emails freelancers and consultants who write about pricing, and offers the tool as a resource for their readers.
The result: dozens of relevant sites link to the calculator, and the tool page climbs into the top rankings for its terms.
Why it works: the page earns links because it is worth linking to, which is the only link strategy that lasts.
Quick Tip
Before chasing a link, ask whether the page would attract the link if nobody asked. If not, improve the page first.
