Does Google really evaluate each page individually, or does it still consider domain authority?

Does Google deny the existence of domain authority?

This statement reflects a classic position from Google: the algorithm does not assess an overall authority score at the domain or subdomain level. Each URL is analyzed for its own content and the incoming links it directly receives.

This approach stems from the architecture of the original PageRank: link juice flows between pages, not between domains. A well-linked Page A transmits value to a Page B through an internal link, but it is not the domain that magically 'boosts' all its pages.

Why does this page-by-page distinction matter?

If Google evaluates each URL individually, this means that creating 100 mediocre pages does not automatically improve the visibility of your homepage. Each page must earn its ranking based on its content and direct backlinks.

In practice, this implies that an orphan page – even an excellent one – remains invisible if it does not receive external links or internal linking. Google may crawl it, but without popularity signals, it will remain at the bottom of the index.

Is a subdomain treated as a distinct domain?

Google specifies that subdomains and main domains are evaluated with the same logic: no global treatment. A subdomain blog.site.com does not automatically benefit from the authority of site.com.

This statement has implications for multi-domain or multi-subdomain strategies. If you isolate your blog on a subdomain, expect to have to link from the main domain to transfer juice, just as you would for an external site.

• Each page is evaluated based on its own content and direct backlinks
• The domain or subdomain does not provide any automatic boost according to Google
• A page without incoming links (internal or external) remains invisible even on a powerful site
• Internal linking becomes a critical lever for distributing authority among pages
• Subdomain strategies must incorporate an explicit cross-linking policy

Is this statement consistent with on-the-ground observations?

Let's be honest: this official position obscures part of the reality. On the ground, established sites enjoy visible advantages. A new page on an authoritative domain typically ranks faster than an identical page on a young site, given equal backlinks.

Google is not technically lying: there is no 'domain authority' metric in the algorithm. However, the cumulative effect of a dense link profile, high crawl budget, regular content freshness, and optimized internal structure effectively creates a systemic advantage. Whether you call this 'domain authority' or 'the sum of page-level signals' does not change the outcome for a practitioner.

What nuances should be added to this statement?

The devil is in the details. Yes, Google evaluates each page individually, but it does so in a crawl context that depends on the domain. A site with 10,000 quality backlinks gets crawled more deeply and frequently than a freshly installed WordPress blog.

As a result, your new pages on a strong domain are discovered and indexed within hours. On a weak domain, it takes weeks. This difference in indexing speed and crawl frequency creates a mechanical competitive advantage, even if the ranking algorithm remains page-centric. The exact extent of this effect is still [To be verified], as Google has not released any quantitative data on the correlation between crawl budget and ranking speed.

In what cases does this rule not fully apply?

Brand queries introduce a bias: if your domain is recognized as an entity in the Knowledge Graph, Google favors your pages even if they are less optimized on searches including your brand name. This is not domain authority in the SEO sense; it is entity recognition, but the effect is similar.

Moreover, sites subjected to algorithmic penalties (Panda, Spam Update) see all of their pages demoted, even those without intrinsic issues. Google does apply domain-level filters in certain contexts, partially contradicting its official discourse.

What practical steps should be taken to optimize page by page?

The first step: audit your internal linking structure. If Google judges each page based on its links, then a strategically important page that is poorly linked internally will remain invisible. Use Screaming Frog or Oncrawl to identify orphan or under-linked pages.

Next, distribute your external link building efforts to the pages that need it, not just the homepage. A product page without backlinks will never rank on a competitive query, even if your homepage has 10,000. Diversify your anchors and targets.

What mistakes should be avoided in this page-centric logic?

Classic mistake: creating content in bulk based on volume. If each page must earn its ranking, 1,000 mediocre pages are not worth 10 excellent ones. Google does not reward raw quantity at the domain level.

Another pitfall: neglecting deep internal linking. Many sites concentrate their internal links on Level 1-2 pages, leaving deeper pages without juice. As a result, these pages never appear, even with good content, because Google never sees them as a priority.

How can I check that my site adheres to this logic?

Launch a full crawl and analyze the distribution of internal PageRank (InRank in Oncrawl, Internal PageRank in Screaming Frog). Strategic pages should have a high score, otherwise, they will not receive enough signals to rank.

Cross this data with your actual positions: if a well-linked internal page does not rank, it is likely a problem of content or external backlinks. If a poorly linked internal page does not rank, start by correcting the links before seeking external backlinks.

• Audit orphan pages and inject internal linking into them
• Distribute external backlinks to strategic pages, not just the homepage
• Avoid creating bulk content without a linking strategy
• Optimize internal linking to push priority deep pages
• Monitor InRank or internal PageRank to detect imbalances
• Cross-reference actual positions and internal signals to diagnose blockages
