Check any domain's Health Score, Link Power Score, Search Traffic Score, and Naturalness Score in one report. Benchmark SEO health, backlink quality, and traffic strength against competitors — no login required.
A Website Health Score is a composite SEO metric that summarizes how strong and trustworthy a domain looks based on its backlink profile, organic traffic signals, and link naturalness. Higher scores generally mean a healthier mix of authority, traffic, and clean link patterns.
Important: This score is a third-party Semrush-based estimate. It is not Google's official ranking score, and it is different from a full technical site audit (page speed, crawl errors, Core Web Vitals). Use it to compare domains quickly and spot SEO health differences between you and your competitors.
SEO platforms measure "site health" in different ways:
This tool (Semrush domain health metrics) — Shows Health Score, Link Power, Search Traffic Score, Naturalness Score, Authority Score, backlinks, and referring domains for any domain you enter.
Semrush Site Audit / SEO Checker — Crawls your pages for technical issues like broken links, indexability problems, and on-page errors. That is a deeper site-wide audit.
Authority Score — A related Semrush metric focused on overall domain strength. You can also check it with our Website Authority Checker.
Start here for a fast domain-level health snapshot. Use a full site audit when you need a page-by-page technical checklist.
Marketers use health and SEO scores to compare domains before investing in content, outreach, or technical work. Our free checker gives you that snapshot without signup.
Use it to:
✅ Benchmark competitors — Compare Health Score, Link Power, and Search Traffic Score across rival domains.
✅ Judge backlink quality — Link Power and Naturalness help you see whether a site's links look strong and natural.
✅ Vet link prospects — Before guest posts or partnerships, check whether a site's health metrics look solid.
✅ Track progress — Re-check your domain over time to see if SEO and link-building work is improving the scores.
✅ Prioritize next steps — A low Search Traffic Score or Naturalness Score points to different problems than a low Link Power Score.
Run your domain, then run 2–3 competitors and compare the same metrics side by side:
• Health Score difference — Who has the stronger overall domain health signal.
• Link Power difference — Who has the stronger backlink profile.
• Search Traffic Score difference — Who is capturing more organic visibility.
• Naturalness difference — Whose link profile looks cleaner and less manipulative.
The competitor with the biggest lead in Link Power and Search Traffic Score is usually the best model for your next content and outreach priorities.
Follow these steps to analyze any domain or subdomain:
1. Go to the Website Health Score Checker page.
2. Enter a domain (for example, google.com or yoursite.com).
3. Complete the security check and click Search.
4. Review the report — Health Score, Link Power, Naturalness, Search Traffic Score, and related domain metrics.
5. Run the same check on competitor domains to build a quick comparison snapshot.
Each search returns a domain health overview powered by Semrush data, including:
An overall score for the domain's SEO health based on Semrush's health signals. Higher scores generally mean a stronger, cleaner domain profile.
Measures the strength of the site's backlink profile — both quantity and quality of links. Stronger Link Power usually supports better ranking potential.
Rates organic search traffic strength on a scale (shown as X/10 in the report). Useful for comparing visibility between your site and competitors.
Estimates how natural the site's backlink and SEO patterns look. Over-optimized or manipulative link profiles often score lower.
Semrush's 1–100 domain strength rating. Complements Health Score when you want a broader authority benchmark.
Total inbound links pointing to the domain. Review with referring domains to understand link profile size.
Unique websites linking to the domain. More quality referring domains usually support stronger SEO health over time.
Improve health metrics by strengthening clean links, growing real organic traffic, and avoiding spammy SEO patterns:
Earn quality referring domains — Digital PR, original research, and useful tools attract natural backlinks that raise Link Power.
Grow organic traffic — Publish pages that match search intent. Higher Search Traffic Score usually follows better rankings and content coverage.
Keep the link profile natural — Avoid paid link schemes, private blog networks, and unnatural anchor patterns that can hurt Naturalness Score.
Compare and close gaps — If competitors score higher on Link Power or Search Traffic, study their referring domains and top content for opportunities.
Maintain the site regularly — Fix broken pages, keep content updated, and use HTTPS. Technical hygiene supports long-term SEO health even when this report focuses on domain-level scores.
There is no single "good" score for every website. Health metrics are relative to your niche and competition.
A high Health Score with strong Link Power and Naturalness is a positive signal. A high Link Power with a low Naturalness Score can mean the site has many links but some look risky or unnatural.
The best approach: check your scores, then check 3–5 direct competitors. Focus first on the metric where the gap is largest — Link Power, Search Traffic Score, or Naturalness.
Yes. You can check any domain without creating an account or signing in.
No. This is a third-party Semrush-based estimate. Google uses its own ranking systems with hundreds of signals.
No. It returns domain-level health metrics (Health Score, Link Power, Search Traffic Score, Naturalness Score, and related authority/backlink stats). For page-by-page crawl errors, use a dedicated site audit tool.
Monthly is enough for most sites. Scores change gradually as backlinks and traffic shift.
Common reasons include weaker backlinks, lower organic traffic, fewer referring domains, or less natural link patterns. Compare each score separately to see where the biggest difference is.
