🔍 What Is a Competitor Domains Test?
A competitor domains test is the process of analyzing a rival website's technical SEO health. It helps you uncover what your competitors are doing right — and what they're doing wrong.
A full competitor domains test typically checks:
- SSL Certificate – Is their site secure? When does it expire?
- DNS Records – Where is their site hosted? What mail servers do they use?
- Meta Tags – What titles and descriptions are they using?
- Redirects – Do they have broken redirects or chains?
- Backlinks – Who links to them? (Requires external tools)
🛡️ Why You Need to Analyze Competitor Domains
📊 Discover Their Strategy
See what keywords they target, how they structure their site, and what content they prioritize.
⚡ Find Their Weaknesses
Expired SSL, broken redirects, or duplicate meta tags — these are opportunities for you.
🔗 Build Better Backlinks
Find out who links to them and reach out to the same sources.
A competitor domains test gives you a clear picture of where you stand compared to your rivals — and what you need to improve to outrank them.
🛠️ Step 1: Check SSL Certificate (SSL Lookup)
SSL security is a ranking signal for Google. If your competitor's SSL is expired or weak, you can leverage your security advantage.
How to run this test: Use Rankcept SSL Lookup and enter the competitor's domain.
What to look for:
- Valid To: Is the certificate expired or expiring soon?
- Issuer: Is it from a trusted source (Let's Encrypt, DigiCert)?
- Cipher strength: TLS 1.2 or 1.3? (1.0 or 1.1 is weak)
Why it matters: An expired SSL certificate causes "Not Secure" warnings that destroy trust and hurt rankings.
🌐 Step 2: Analyze DNS Records (DNS Lookup)
DNS records reveal where a competitor's site is hosted and what mail servers they use.
How to run this test: Use Rankcept DNS Lookup and enter the competitor's domain.
What to look for:
- A Record: The IP address (use a whois tool to find the hosting provider).
- MX Record: Which email provider they use (Google Workspace, Outlook, etc.).
- TXT Record: SPF and verification entries.
- CNAME Record: Subdomain aliases.
Why it matters: Knowing their hosting can help you choose a better provider. Checking their DNS records can reveal misconfigurations you can avoid.
🏷️ Step 3: Extract Meta Tags (Meta Tags Checker)
Meta tags (title, description, robots) are critical for click-through rates and rankings. Seeing what competitors use helps you improve your own tags.
How to run this test: Use Rankcept Meta Tags Checker and enter a competitor's page URL.
What to look for:
- Title length: 50-60 characters is ideal. Longer titles get cut off.
- Description length: 120-158 characters is best.
- Robots: "index, follow" means Google can crawl and index the page. "noindex" means they're hiding it.
- Canonical: Points to the preferred URL version.
Why it matters: If a competitor has better titles and descriptions, they'll get more clicks — even if their content is similar.
🔄 Step 4: Trace Redirects (URL Redirect Checker)
Redirect chains and loops hurt SEO. Competitors often have broken redirects you can learn from.
How to run this test: Use Rankcept URL Redirect Checker and enter a competitor's URL.
What to look for:
- Number of redirect hops: 0-1 is ideal. 3+ slows down their site.
- Status codes: 301 (permanent) is good. 302 (temporary) is not ideal for SEO.
- Redirect loops: A → B → A (very bad).
Why it matters: If a competitor has a long redirect chain, they're losing link equity and speed. You can avoid these issues on your own site.

🔗 Step 5: Analyze Backlinks (External Tools)
Backlinks are the #1 ranking factor. While Rankcept doesn't have a backlink checker yet, you can use free versions of other tools.
Recommended free tools:
- Ahrefs Backlink Checker – Shows top 100 backlinks (free).
- SmallSEOTools Backlink Checker – Simple backlink analysis.
What to look for:
- Referring domains: How many unique domains link to them?
- Authority: DA/DR scores of linking sites.
- Anchor text: What keywords are they using in backlinks?
Why it matters: You can reach out to the same websites that link to your competitors and ask for a link to your content.
