What Are Backlinks? Why They Matter for Search and AI Recommendations
Backlinks – Links from other websites that point to a business's website, serving as trust signals for both search engines and AI platforms.
Every time another website links to a business’s site, that’s a backlink. A local newspaper writes about the best restaurants in town and includes a link to one of them. A wedding blog mentions a florist and links to their portfolio. An industry directory lists a law firm with a link to their homepage. Each of these tells search engines and AI platforms that someone else found this business worth referencing.
Google has used backlinks as a ranking signal since its earliest days, and they remain one of the strongest factors in determining where a website appears in search results. The logic is straightforward: if multiple credible sources link to a business, that business is probably trustworthy and relevant. One link from a respected local news site carries more weight than hundreds from obscure directories, because relevance and authority matter far more than raw numbers.
Backlinks also feed into AI visibility. When ChatGPT or Google AI evaluates which businesses to recommend, mentions and links from authoritative sources increase the model’s confidence. A business referenced in press coverage, “best of” lists, and industry publications is far more likely to show up in AI-generated answers.
For local businesses, the most effective backlinks tend to come from local sources: news outlets, community organizations, local business associations, event sponsorships, and industry-specific directories. These are also the hardest to fake, which is why they carry weight. Getting mentioned in a “best dentists in Denver” article from a local magazine does double duty by improving both Google ranking and AI recommendations.
The businesses that build backlinks most naturally are the ones that give people a reason to link to them: useful content on their website, active involvement in the community, original research, or expertise that journalists want to quote. It’s slower than buying links, but it’s the only approach that compounds over time and works across both traditional search and AI platforms.
Frequently Asked Questions
How many backlinks does a business need?
Quality matters far more than quantity. A single link from a respected local news site or industry publication is worth more than hundreds of links from obscure directories. For most local businesses, even a handful of genuine editorial links from relevant sources makes a meaningful difference.
Can a business buy backlinks?
Buying links violates Google's guidelines and can result in penalties. The links that actually help are earned by doing something worth linking to: publishing useful research, sponsoring a local event, getting featured in a news article, or building a resource that others naturally reference.
Do backlinks matter for AI recommendations too?
Yes. When an AI model evaluates which businesses to recommend, mentions and links from authoritative sources increase confidence. A plumber mentioned in a local newspaper's 'best of' list is more likely to appear in ChatGPT's recommendations than one with no third-party references at all.
