Why Domain Power Checks Matter

Domain Power (Domain Authority) is a metric indicating how much search engines trust a website. Sites with higher domain power tend to rank higher even when publishing articles on the same keywords.

Backlinks are the most influential factor on domain power. Links from authoritative sites like government agencies (.go.jp), educational institutions (.ac.jp), and major media significantly boost domain power. Conversely, links from low-quality spam sites can have a negative effect.

Regular domain power checks help you objectively measure the effectiveness of your SEO efforts. CodeQuest.work SEO_CHECK displays domain power on a 0–10 scale, enabling comprehensive diagnosis alongside your SEO score.

FAQ

What is Domain Power?▾
Domain Power (Domain Authority) is a metric that quantifies how much trust a website's domain has earned from search engines. Our tool uses the Open PageRank API and measures on a 0-10 scale.
What is a good Domain Power score?▾
0-2 indicates new/small sites, 2-4 growing sites, 4-6 established sites, and 6+ major/authoritative sites. New domains start near 0 and gradually improve with quality content and backlinks.
How can I improve my Domain Power?▾
Key factors include acquiring quality backlinks, consistently publishing high-quality content, domain age, and technical SEO (page speed, HTTPS). Significant improvement takes time and sustained effort.
How does this differ from Ahrefs DR or Moz DA?▾
Ahrefs (DR) and Moz (DA) use proprietary calculation methods with different scoring criteria. Our tool uses Open PageRank, a successor to Google's former public PageRank. Relative comparison with competitors matters more than absolute values.
Why is my Domain Power 0?▾
New domains, sites with very few backlinks, or sites without sufficient crawl data may show a score of 0. Building content and acquiring backlinks will improve the score over time.
What's the difference between SEO Score and Domain Power?▾
SEO Score evaluates individual page optimization (meta tags, structured data, content quality). Domain Power measures overall domain trust from search engines. Improving both leads to better search rankings.
