In SEO, two levers consistently stand out: backlinks and domain authority. They form the foundation on which Google assesses a site's credibility. Without a solid link-building strategy, even flawless content will struggle to emerge. Explanations, examples and best practices.
What is domain authority?
Domain authority is a predictive score that estimates a website's ability to rank in search engines. The higher the score, the more reliable and influential the site is considered to be. These include DA (Domain Authority), developed by Moz, and DR (Domain Rating), used by Ahrefs. Both metrics are based mainly on the quantity and quality of backlinks pointing to a domain.
In practice, a site with a DA/DR of 70+ will find it much easier to rank for a competitive keyword than a new site with a score of 10. It is a virtuous circle: backlinks increase authority, and authority gives more weight to published content.
Why backlinks remain essential for SEO
Backlinks are still perceived as "votes" in favour of your site. Every external link acts as a recommendation. A Backlinko study covering more than a billion pages shows a clear correlation between the number of backlinks to a page and its Google ranking.
However, quality matters more than quantity. A few key points to remember:
- The relevance of the source site: a link from a site in the same topic area will carry more value.
- The link anchor: an anchor containing your main keyword is a strong signal, provided you do not overuse it.
- The authority of the source page: a link from a page that itself has a good DR/DA carries more weight.
Unfortunately, many businesses embark on risky link-building strategies: spammy directories, mass link exchanges, buying low-cost packages. These practices are risky and can lead to a manual Google penalty. One quality backlink a month is better than fifty toxic links.
Link building: best practices for improving DR DA
Link building refers to all the techniques used to obtain external links. To improve your domain authority, you need to adopt a methodical and sustainable approach.
1. Create content that deserves links
Case studies, ultimate guides, exclusive data or free tools naturally attract backlinks. This is the foundation: no one shares weak content. Think in terms of comprehensive, up-to-date resource pages.
2. Focus on quality guest blogging
Offering guest articles on already well-ranked sites is still effective. The aim is to reach their audience and obtain a contextual backlink. Check the site's DR/DA, but also its actual organic traffic. A site with a high DA but no traffic can be suspicious.
3. Analyse your competitors' backlinks
With Ahrefs or SEMrush, audit the domains that link to your direct competitors. These are ideal targets: they are already receptive to your topic. Identify those that reference several competitors and assess their "Link Velocity" before contacting them.
4. Local and sponsored link building
Local partnerships (chambers of commerce, associations, regional press) remain a source of natural links. On the other hand, sponsored articles on authoritative sites are a powerful lever, provided the content is transparent and useful.
DR vs DA: what are the differences for your strategy?
Many experts confuse DR and DA. Ahrefs' DR (Domain Rating) measures the strength of a root link profile, on a logarithmic scale from 0 to 100. Moz's DA (Domain Authority) also incorporates other signals, such as data from its index. In practice, these two metrics remain correlated.
What to remember: use DR/DA as a starting indicator, not as an absolute truth. A site with a DA of 40 in a specific niche can outperform a generalist site with a DA of 50, because its topical relevance is greater. Also assess estimated traffic and the reliability of referring domains.
Your goal: gradually improve your own domain authority. Do not focus on an absolute value, but on a positive trajectory.
Conclusion
Backlinks and domain authority form an essential duo for dominating search results. A coherent link-building strategy, supported by indicators such as DR/DA, allows you to achieve sustainable organic growth.
