How to Get Backlinks: Ethical Link Building Within Google's Rules

A backlink is a link from another website to your page. Google uses links to discover new pages and to understand how much a page is referenced, so links from trustworthy sites related to your topic support your visibility. Lasting backlinks are earned through content people cite of their own accord and through real relationships; buying or trading links violates Google's spam policies.

That is why the honest answer to "how do you get backlinks?" has two parts: knowing what works matters as much as knowing what will hurt your site.

Which backlinks are actually valuable?

Not all links are equal. A valuable link usually combines these qualities:

• Topical relevance: The linking site and page are related to your subject. For accounting software, a link from a blog for accountants means more than one from an unrelated recipe site.
• Context: The link sits in a sentence that supports a claim or points the reader to more information. It is not lost in a list of a hundred links at the bottom of a page.
• Real readers: The linking site has its own readers and search traffic. Sites that nobody reads, set up only to publish links, carry no value.
• Natural anchor text: The anchor text is usually your brand name, your page title or a natural phrase. If every link arrives with the same keyword, it looks artificial.

Scores such as "domain authority" from third-party SEO tools are useful for comparison, but they are not a measure Google uses. Make your decision based on the four questions above, not on a score.

What does Google treat as link spam?

Google's spam policies define link spam as creating links for the purpose of manipulating search rankings. The examples the policy lists explicitly are:

• Buying or selling links for ranking purposes: paying for links, exchanging goods or services for links, or sending someone a product in exchange for a post with a link
• Excessive link exchanges ("link to me and I'll link to you") and partner pages created exclusively for cross-linking
• Using automated programs or services to create links to your site
• Requiring a link as part of a terms of service or contract without allowing the content owner the option of qualifying the link
• Links from low-quality directory and bookmark sites
• Links spread across the footers or templates of many sites
• Forum comments with optimized links in the post or signature
• Advertorials published for payment that contain links passing ranking credit

Most services sold on the market as a "backlink package" or a "sponsored article on a news site" fall into this list. They can seem to work in the short term, but when Google applies a manual action or simply ignores the links, the effort and budget are wasted.

Are paid links and sponsored articles banned entirely?

No. Sponsorship, advertising and advertorials are legitimate marketing tools; the rule is that these links must not pass ranking credit. According to Google, a paid link does not violate the policy when it is marked with rel="sponsored" or rel="nofollow".

Google's documentation on qualifying links separates the three values like this:

• rel="sponsored": Links that are ads or paid placements
• rel="ugc": Links inside user-generated content, such as comments and forum posts
• rel="nofollow": For cases where the others do not fit and you do not want your site associated with the linked page

If you publish a sponsored article on a news site, the goal should be to reach that site's readers. Google's site reputation abuse policy separately treats third-party content hosted to take advantage of another site's existing ranking signals as a violation, while it keeps promotional content presented directly to readers outside that scope.

How do you earn backlinks ethically?

A lasting link starts with producing something others want to cite. Methods that work:

1. Reference-quality content: An industry survey built on your own data, a calculator, an up-to-date guide that explains regulation in plain language. Journalists, bloggers and academics look for sources, and first-hand information earns links.
2. Digital PR: Offering the trade press a newsworthy development, an expert opinion or data. The aim is not to ask for a link but to contribute to the story; the link often comes as a result.
3. Unlinked mentions: Find pages that mention your brand name without linking to you, and politely suggest that the author add a link. It is the easiest request to make to a source that already knows you.
4. Real relationships: Reference pages of suppliers, dealers and business partners, the professional chamber or association you belong to, and pages for events where you spoke. These links are natural because they reflect a real business relationship.
5. Broken link opportunities: Find links on industry sites that point to a resource that no longer opens, and suggest your own content on the same topic as a replacement.
6. Community: Be present in industry forums and communities to answer questions, not to drop links. We explain its indirect contribution to search visibility in our post on brand visibility in the AI era.

Guest posting can belong on this list too, but scale matters. A single article that adds real value in a relevant publication with an actual readership makes sense; articles sent to hundreds of sites with the same anchor text move toward the spam examples above.

Before you earn links, the page itself needs to be ready. A link to a page with a weak title, thin content and poor internal linking has limited effect; for the basic checks, see our on-page SEO guide.

How do you monitor your backlink profile?

The starting point is the Links report in Google Search Console. It shows the sites that link to you most, your most-linked pages and the most common anchor texts. According to Google's documentation, the report shows a sample rather than every link, and it does not indicate whether a link is nofollow. For a more detailed view, third-party tools can be used alongside it.

When monitoring, look at:

• Which sites new links come from and whether they are related to your topic
• The distribution of anchor texts: brand and natural phrases, or a single keyword?
• Clusters of irrelevant or spammy-looking links that appeared without your knowledge

There is no need to panic when you see spammy-looking links. In its documentation on disavowing links, Google states that most sites do not need this tool and that Google can usually assess which links to trust without additional guidance. Use the disavow tool only when both conditions are true: a large number of spammy, artificial or low-quality links point to your site, and these links have caused a manual action or are likely to.

A backlink checklist

• First, have a page worth linking to: reference-quality, current and well structured.
• Focus on links that bring topical relevance, context and real readers.
• Do not buy links or get into exchange loops; ask for sponsored or nofollow on paid placements.
• Review places where your brand is mentioned without a link, and your business partners.
• Check the Search Console Links report once a month; use the disavow tool only when necessary.
