Growth Score vs Authority Score vs Domain Rating: what actually predicts revenue

The score most marketers stare at is wrong

Domain Rating, Authority Score, Trust Flow — these metrics measure one thing: how likely your site is to rank if you put the right page in front of Google. They were designed in a world where ranking = traffic = revenue.

That chain broke around 2020.

Today you can rank #1 for a keyword and still not generate pipeline, because:

• Users bounce on a slow landing page
• Your primary CTA is buried below the fold
• The headline promises one thing and the page delivers another
• Your trust proof is below the scroll line on mobile
• Your pricing page has 7 options when buyers need 3

None of that shows up in DR or AS. You''d have a "strong" site by every legacy metric and still lose revenue every week.

What a Growth Score actually measures

A Growth Score is a composite — a weighted blend of four pillars, each predicting a different part of the traffic-to-revenue chain.

Pillar 1: SEO foundation (25%)

The technical and on-page bedrock: title/H1/meta hygiene, internal linking depth, structured data, crawl health, schema. DR/AS cover some of this. Growth Score covers it in context — a missing H1 on your pricing page costs more than on your /about page.

Pillar 2: Conversion readiness (30%)

This is where DR collapses as a useful metric. Growth Score scores:

• Primary CTA clarity (is there one, and is it visible above fold?)
• Trust signals (social proof, logos, reviews, case studies)
• Friction in the primary action (form fields, friction before sign-up)
• Pricing transparency
• Speed on the money pages (not just the homepage)

Pillar 3: Pipeline mechanics (20%)

Does your site actually capture intent? Lead forms, chat surfaces, demo-booking flows, exit-intent hooks. Rankable content with no capture path is a vanity metric.

Pillar 4: Content depth (25%)

Not word count — relevance. Does the site cover the topic cluster deeply enough to be considered authoritative by both users and LLMs? This is where 2026 content also starts to factor in AI Visibility — does ChatGPT or Perplexity cite this site when asked?

Why the weighting matters

A Shopify store with a beautiful blog but a terrible checkout page will have a strong Ahrefs DR and a weak Growth Score. That''s correct. The site ranks, but it bleeds revenue in the last mile.

A B2B SaaS with minimal backlinks but perfect signup conversion will have a weak DR and a strong Growth Score. That''s also correct — the site is already converting the traffic it has, which is the definition of a scalable business.

How to read your Growth Score

• 80-100: Strong. Your bottlenecks are outside the site (ad spend, demand gen, sales).
• 65-79: Fixable fast. 3-5 specific changes will unlock material lift in 30 days.
• 50-64: Structural issues. A rebuild of 1-2 surfaces (pricing page, signup flow, homepage hero) is likely required.
• Under 50: Start over. The site is actively leaking pipeline.

The practical move

If you''ve been tracking DR/AS for years, don''t throw them out — they''re useful for ranking forecasts. Just add a Growth Score alongside them. When DR goes up but revenue doesn''t, the Growth Score will tell you why.
