How Backlinks Actually Work (the 2024 Reality)
Backlinks are still one of the most powerful ranking signals in SEO, but how Google values them changed significantly in 2024, and the old volume-first approach now actively hurts sites.
A backlink is a link from one website to another. To understand how backlinks work, picture a vote. When a trusted site links to yours, it tells Google your page is worth referencing. It is a digital endorsement of your authority. Backlinks are still one of the top three ranking factors in Google's algorithm. But the 2024 updates changed the rules. They reset which backlinks help, which do nothing, and which can hurt your site.
The days of counting links are over. Now Google looks at quality, relevance, and editorial context. It studies the sites that link to you. One link from a respected industry publication beats hundreds from weak directories or private blog networks. And those weak links now carry real penalty risk. The March and May 2024 spam updates made sure of that.
How does Google decide a backlink is valuable?
Google looks at many things. It checks authority. Does the linking site have real traffic? Does it have an audience? Has it earned trust? It checks relevance. Is the linking site about a topic close to yours? It checks editorial context. Was the link placed naturally inside content? Or was it in a footer, sidebar, or paid spot? It checks anchor text. Does the anchor text match the linked page? Across all your links, does the mix of anchor text look natural?
A link from a big news site helps. It must cover your field. This kind of link has real power.
A link from a niche blog with a real, engaged audience in your field is highly valuable.
A link from a directory with no editorial standards and thousands of identical listings adds almost nothing.
A bought link from a private blog network breaks Google's guidelines and risks a penalty.
What changed in 2024's spam updates?
Google's March 2024 spam update went after three common tricks. The first is expired domain abuse. That means buying old domains with inherited authority and redirecting them as link sources. The second is scaled content abuse. That means building sites only to host guest posts and pump out links. The third is site reputation abuse. That means big sites letting third-party content slip in as a backdoor for link injection. For years, these worked as grey-to-black hat link schemes. In 2024, Google moved to devalue or penalise them at scale.
In 2024, a hundred bought links is a liability, not an asset. Google can spot link schemes far better than it could in 2021. And the downside has never been steeper.
How do you earn backlinks that actually help?
Real link building is digital PR. You create content or tools. Authoritative sites want to cite them. Build relationships. Put your work in front of the right people. This takes time. It's slower than buying links. But it compounds. Earned links attract more links over time. Credibility draws credibility.
Publish original research, surveys, or data that journalists and bloggers cite as a source.

Does the number of backlinks still matter at all?
Volume still matters. But not as much as quality. Ahrefs shows a clear pattern: Top pages have more backlinks than lower-ranked ones. Why? Quality is key. Pages with natural links get more over time. Faking volume won't work like before 2024. The March 2024 core update shows why: Google now judges link quality better. Quality matters even more than it used to.

Frequently asked questions
Should I disavow old bad links I didn't build?
Use the disavow tool with care. Google says to use it only in two cases. One, you have a manual action, or penalty, caused by unnatural links. Two, you are sure that a large part of your backlink profile is spammy. For most sites, Google's algorithms already discount weak links. Disavowing too broadly can remove links that are helping you. So use it surgically, not broadly.
How long does it take for a new backlink to affect rankings?
Google has to crawl the linking page first. That can take days or weeks. After that, the signal counts at the next ranking update. Google does this on a rolling basis. In practice, strong backlinks from strong domains can move rankings. This takes two to six weeks.
