Domain Authority: the influence of a site perceived by LLMs
Description
Domain authority measures a website's credibility and reputation based on its history, the quality of its backlinks, thematic consistency, and peer recognition. It is gradually established through publishing content, obtaining natural links from authoritative sources, and demonstrating expertise in a specific field.
It's important to note that DA is not a direct ranking factor used by search engines or LLMs, but it is widely recognized as a reliable indicator of a website's overall strength and ability to rank.
Why is this important for ai search?
LLMs incorporate domain authority as a weighting factor when selecting sources for their answers. A domain recognized as an expert in its sector is more likely to be cited and referenced.
It should be noted that brand authority has a greater influence on the trust placed in information by models, which may prioritize established sources. The brand can therefore be cited without any link to the site.
Technical details
- Calculating Domain Authority
- Increase Your Domain Authority
1. Calculating Domain Authority
Domain Authority (DA) is a score from 1 to 100, where a higher score indicates a greater likelihood of ranking in search engines.
Moz calculates Domain Authority by evaluating many factors, including the number of linking root domains and the total number of links. This score is then used to rank websites on a logarithmic scale, meaning it's much harder to increase your score from 70 to 80 than it is to increase it from 20 to 30. Moz updates its DA calculation algorithm regularly to reflect changes in the web landscape.
In the context of Generative Engine Optimization (GEO), Domain Authority takes on particular importance. Generative AI engines, such as ChatGPT, Perplexity, or Google Gemini, rely on the credibility and authority of sources to generate reliable and relevant answers. A site with a high DA is perceived as a more reliable source of information and is therefore more trusted by these engines.
2. Increase Your Domain Authority
Several factors contribute to the calculation of Domain Authority. Understanding these factors is essential to developing an effective improvement strategy:
- Quality and quantity of inbound links (backlinks): This is the most influential factor. Links from high-authority and relevant websites are more valuable.
- Domain age: Older, established domains tend to have a higher DA because they have had more time to accumulate authority.
Improving Domain Authority is a long-term process that requires a holistic approach. Here are some key strategies to achieve this:
- Acquiring quality backlinks: Implement an ethical netlink building strategy. This includes outreach to other relevant sites, creating shareable resources, participating in industry events, and reclaiming broken links.
- Content Promotion: Share your content on social media, in newsletters, and through other channels to increase its visibility and reach, which can lead to more organic links.
