A backlink is a hyperlink on one website that points to a page on another website. Search engines read backlinks as a signal of trust: when a relevant, credible site links to you, it counts as a vote of confidence. Backlinks remain one of the strongest ranking factors Google uses, alongside content quality and on-page SEO.
For a local service business, backlinks work like word-of-mouth referrals turned into code. A roofing contractor mentioned by the local chamber of commerce, a supplier, or a news site earns more trust in Google’s eyes than one with no outside mentions at all. This ties directly into domain authority and how competitive keywords become winnable.
Key takeaway
Not all backlinks are equal. A single link from a relevant, trusted site can outweigh dozens of low-quality directory links, and some links can actively hurt you.
How backlinks work
Backlinks work by passing trust and relevance signals from the linking page to the linked page, which search engines factor into ranking decisions.
When Google’s crawler finds a link, it evaluates the linking page’s authority, topical relevance, and the anchor text used. This is part of what older SEO discussions called link juice, a shorthand for the value passed through a link. Google has confirmed that links remain one of several major ranking signals, not the only one.
Why backlinks matter, and what they don’t do
Backlinks matter because they help search engines gauge trust and discover new pages, but they don’t guarantee a ranking on their own if the content or site experience is weak.
A page stacked with backlinks but thin content, slow load times, or poor user experience can still underperform. Backlinks are one input among many, including Core Web Vitals, search intent match, and E-E-A-T signals.
Types of backlinks
The main backlink types are editorial links, guest post links, directory or citation links, and links from social or forum profiles, each carrying a different level of trust.
| Type | Example | Typical value |
| Editorial | News site mentions your business naturally | High |
| Guest post | You write an article for an industry blog | Medium to high |
| Local citation | Chamber of commerce or local directory listing | Medium |
| Low-quality directory | Mass-submitted, unmoderated link farms | Low or risky |
Backlink vs internal link
A backlink comes from a separate website, while an internal link connects pages within your own site.
| Backlink | Internal link |
| From another domain | From your own domain |
| Builds external trust | Spreads authority and improves crawlability |
| You have limited control over it | You control it fully |
Internal links still matter for the same reasons backlinks do, just at a smaller scale. See internal linking for how the two work together.
Good vs bad backlink examples
A good backlink comes from a relevant, real site with genuine traffic; a bad one comes from an unrelated, spammy, or paid link network.
- A local news outlet covers your HVAC company’s community fundraiser and links to your site.
- An industry association lists your business under verified members.
- A supplier’s website links to your page as an authorized dealer.
- Buying hundreds of links from a private blog network overnight.
- Getting listed on unrelated foreign-language directories with no real audience.
- Exchanging links in bulk with unrelated businesses just to inflate link counts.
Costly mistake Assuming more backlinks always means better rankings. A sudden spike of low-quality links can trigger a manual action or algorithmic devaluation instead of a boost.
How to check your backlinks
Check your backlinks using Google Search Console’s Links report, which shows top linking sites, top linked pages, and top anchor text for free.
Go to Search Console and open the Links section under the left menu. It won’t show every link a paid tool would, but it reflects what Google itself has recorded. For a fuller audit, including toxic link detection, pair it with a third-party crawler.

Common backlink mistakes and myths
The most common myth is that any link helps, regardless of source; in reality, irrelevant or spammy links can trigger penalties or simply carry no weight.
Another frequent mistake is chasing raw link count instead of relevance. Ten links from local, topically related sites usually outperform a hundred random ones. Businesses also forget to vary anchor text, which can look manipulative if every link uses the exact same keyword phrase.
How to improve your backlink profile
- Audit existing links. Pull your Search Console Links report and flag anything from unrelated or spammy domains.
- Earn local coverage. Sponsor a community event or offer expert commentary to local journalists for natural mentions.
- Fix or disavow toxic links. Request removal first, and only use the disavow tool for links you can’t get taken down.
- Build topical relationships. Partner with suppliers, associations, and complementary local businesses for genuine links.

FAQ
Do backlinks still matter in 2024?
Yes. Google continues to cite links as a core ranking signal, though content quality and user experience now carry more combined weight than in the past.
How many backlinks do I need to rank?
There’s no fixed number. Relevance and authority of the linking sites matter far more than total count, and competitive keywords generally need more.
Can backlinks hurt my SEO?
Yes. Spammy, irrelevant, or paid link schemes can trigger a manual action or reduce trust in your site, especially if they appear suddenly in large volumes.
What is a nofollow backlink?
It’s a link with a rel=”nofollow” attribute, signaling search engines to not pass ranking credit, though Google may still consider it as a hint.
