Compare two websites side by side — Authority Score, organic traffic, ranking keywords, backlinks, referring domains, and more. Benchmark your site against any competitor in seconds. No login required.
A domain comparison tool lets you analyze two websites side by side across the SEO metrics that matter most — Authority Score, organic traffic, ranking keywords, backlinks, and referring domains. Instead of opening two separate reports and switching tabs, you get one clear table that shows who leads on each metric.
Powered by Semrush search and backlink data, this free Compare Domains checker helps marketers, agencies, and site owners benchmark competitors quickly before planning content, outreach, or quarterly SEO reviews — with no account signup required.
• Step 1: Enter your primary domain — Type your website (e.g. toolxox.com) into the first field. Root domains work best for a fair overview.
• Step 2: Enter a competitor — Add the rival domain you want to benchmark (e.g. snapwordz.com).
• Step 3: Select the Semrush database / region — Choose the country market you care about (e.g. United States, India, United Kingdom). Organic traffic, keywords, and domain rank are compared for that database.
• Step 4: Complete the security check — Solve the Turnstile captcha, then click Compare Domains.
• Step 5: Read the leader column — For each metric, the report highlights which domain is ahead so you can spot gaps in traffic, keywords, or backlinks immediately.
• Step 6: Repeat with other rivals or regions — Run the same check against more competitors or switch databases to see regional differences.
Each search returns a side-by-side Semrush-powered snapshot, including:
Semrush’s 1–100 rating of overall domain strength. It factors in backlink quality, organic traffic signals, and spam checks — useful for comparing SEO strength within the same niche.
Estimated monthly visits from unpaid search. A larger gap here usually means the winning site ranks for more (or better) keywords.
How many keywords each site appears for in search results. More ranking keywords often signal a wider content footprint.
Popularity rank in the US database. Lower is better — a smaller number means stronger relative visibility in Semrush’s index.
Total inbound links and unique linking websites. Referring domains usually matter more than raw backlink counts for long-term authority.
Quick signals of backlink profile quality, link strength, and traffic contribution — helpful when vetting competitors or link prospects.
See how much demand comes from brand searches versus generic queries, plus an estimated dollar value of organic traffic if bought via ads.
Competitive SEO starts with knowing where you stand. A clear domain comparison shows whether a rival has stronger backlinks, more ranking keywords, or higher estimated organic traffic — so you can focus on the gaps that matter most.
✅ Benchmark competitors — See who leads on Authority Score, keywords, and traffic before you invest in content or outreach.
✅ Spot link-building gaps — If a competitor has far more referring domains, study their profile and find similar prospects.
✅ Prioritize content opportunities — A large keyword lead often means topic clusters and landing pages you have not covered yet.
✅ Track progress over time — Re-run the same pair every few weeks to check whether your SEO work is closing the gap.
✅ Pitch smarter to clients — Agencies can show prospects a clear before/after style comparison versus category leaders.
For most metrics, higher is better (Authority Score, traffic, keywords, backlinks, referring domains). For Semrush Domain Rank, lower is better — the domain with the smaller rank number is the leader.
• Authority lead but keyword lag — They may have stronger links; double down on content volume and keyword targeting.
• Keyword lead but traffic lag — They rank for many low-volume terms; look for higher-intent, higher-volume queries.
• Backlink lead with weak health — Quantity without quality; prioritize clean, relevant referring domains over spammy volume.
• Close scores across the board — Compete on pages, SERP features, and conversion — not just raw authority.
• Compare domains in the same niche and business model — comparing a SaaS tool to a news site is rarely useful.
• Stick to one metric system (Semrush Authority Score here) so numbers stay consistent.
• Always pair overview metrics with deeper tools like Organic Keywords Checker and Website Authority Checker.
• Check 2–5 direct competitors, not just the market leader — mid-tier rivals often reveal more realistic opportunities.
• Revisit monthly — authority and traffic change gradually, but sudden drops can signal lost links or algorithm impact.
Q: Is this compare domains tool free?
A: Yes. You can compare any two domains without creating an account or signing in.
Q: Where does the data come from?
A: Metrics are powered by Semrush JSON-RPC endpoints for organic summary and backlink profile data — the same style of API used by our Website Authority Checker (API keys only; no browser cookies required on your side).
Q: Why is Authority Score higher but traffic lower?
A: Authority reflects link and trust signals; traffic depends on rankings and search demand. A strong backlink profile does not automatically mean more visible keywords.
Q: Why does Domain Rank use “lower is better”?
A: Semrush Domain Rank is a ranking position in the database. A smaller number means stronger relative popularity, so the leader is the domain with the lower rank.
Q: Can I compare more than two domains?
A: This tool compares one pair at a time. Run additional comparisons for each competitor and keep notes — or use related tools for keyword-level depth.
Q: Does Google use Authority Score?
A: No. Authority Score and similar third-party metrics are estimates for comparison and planning. Google uses its own ranking systems.
