How to Increase Your Domain Authority: 11 Methods That Still Work
Quick answer: Domain Authority (DA) is a score from 1 to 100, created by the SEO company Moz, that estimates how likely a website is to rank in search results. Google doesn’t use it, but it’s a useful health check. You increase it the same way you earn real rankings: by publishing genuinely useful content, earning links from trusted websites, and keeping your site fast, secure and easy to crawl.
Below are 11 methods that still work, updated for how search engines and AI assistants find businesses today.
1. Choose a clear, relevant domain name
A short, memorable domain that matches your brand makes it easier for people to find you, link to you and remember you. If most of your customers are local, a country-code domain such as .com.au signals that your business serves Australia, which helps in local results.
2. Clean up harmful links
Links from spammy directories, scraper sites and link farms can drag your site down. Review the sites linking to you using a backlink tool, ask for removal of anything clearly spammy, and use Google Search Console’s disavow tool only for genuinely toxic links you can’t remove.
3. Earn links from trusted websites
Links from respected, relevant websites are still one of the strongest signals of authority. The best links are earned, not bought: guest articles for industry publications, interviews and podcasts, local business associations, suppliers and partners, and being quoted as an expert by journalists.
4. Publish content worth referencing
People link to content that helps them: original insights, clear how-to guides, checklists, data and honest opinions. Content that answers real questions in depth is also what AI assistants draw on when they recommend sources. Aim to be the most useful page on the topic, not the longest.
5. Answer questions directly
Search engines and AI tools favour pages that answer a question clearly and early. Start key articles with a short, direct answer, then expand. Use headings that match the questions your customers actually ask, and add a short FAQ where it helps.
6. Build a strong internal linking structure
Link related pages and articles to each other using descriptive anchor text. This helps search engines understand what each page is about, spreads authority across your site and keeps visitors reading for longer.
7. Make your site fast and mobile friendly
Most searches now happen on phones. Compress images, remove unnecessary plugins, use good hosting and test your pages with Google’s PageSpeed Insights. A fast, stable site keeps visitors happy and makes it easier for search engines to crawl.
8. Keep your site secure
An SSL certificate (the padlock and https:// in the address bar) is now the bare minimum. Keep your website software and plugins updated, and use strong logins. Hacked or insecure sites lose trust quickly, with people and with search engines.
9. Help search engines and AI read your site
Submit an XML sitemap through Google Search Console and Bing Webmaster Tools, make sure important pages aren’t blocked, and use structured data (schema) where it fits, such as FAQs, articles and business details. Clear page titles and meta descriptions help both search engines and AI tools summarise your pages accurately.
10. Show who is behind the content
Search engines increasingly look for signs of experience, expertise and trustworthiness. Include author details, explain your experience, keep your business name, address and contact details consistent across the web, and link to your social profiles.
11. Be patient and consistent
Authority is built over months, not days. A steady rhythm of helpful content, earned links and technical care beats any short-term trick. Track your progress in Google Search Console and focus on enquiries and sales, not just the score.
Frequently asked questions
Does Google use Domain Authority?
No. Domain Authority is a third-party metric created by Moz. Google uses its own signals, but because DA is based on similar factors, such as the quality and quantity of links, it’s a reasonable way to compare websites.
What is a good Domain Authority score?
There’s no single good score. It’s best used comparatively: check your score against the competitors who appear for the searches you care about, and aim to close the gap.
How long does it take to increase Domain Authority?
Usually several months. The score updates as new links are discovered, and because the scale is harder to climb at the top, moving from 20 to 30 is much easier than moving from 60 to 70.
