Free Online SEO Analyzer - Check Your Page's SEO Score
Analyze any webpage's SEO health instantly with the UtiliKit SEO Analyzer. Our free tool examines 11 critical ranking factors and provides actionable recommendations to improve your search engine visibility. Whether you're auditing your own website or researching competitors, get detailed insights in seconds.
Simply enter any URL and receive a comprehensive SEO score along with specific recommendations for each element. Our analyzer checks title tags, meta descriptions, headings, images, content length, and more—all the on-page factors that search engines care about.
What We Analyze
📝 Title Tag (15% weight)
The title tag is crucial for rankings and click-through rates. We check for presence and optimal length (50-60 characters). Titles that are too short waste potential; too long get truncated in search results.
📋 Meta Description (12%)
Meta descriptions influence click-through rates from search results. We verify presence and check for optimal length (150-160 characters). A compelling description can significantly improve traffic.
🎯 H1 Heading (12%)
Every page should have exactly one H1 heading that describes the main topic. We check for presence and flag pages with missing or multiple H1 tags, which can confuse search engines.
🖼️ Image Alt Text (10%)
Alt text helps search engines understand images and improves accessibility. We count images with missing alt attributes and calculate coverage percentage.
📊 Content Length (10%)
Thin content often struggles to rank. We analyze word count and flag pages with fewer than 300-500 words. Comprehensive content tends to perform better in search results.
🔗 Internal Links (5%)
Internal links help search engines discover content and distribute page authority. We count internal vs. external links and flag pages with insufficient internal linking.
Additional Checks
- Heading Structure (8%): Proper heading hierarchy (H1→H2→H3) helps search engines understand content organization and improves readability.
- Canonical URL (8%): Canonical tags prevent duplicate content issues. We verify their presence to ensure search engines know which URL to index.
- Mobile Viewport (8%): The viewport meta tag is essential for mobile-friendly pages. Without it, your site may not display properly on mobile devices.
- Open Graph Tags (7%): OG tags control how your pages appear when shared on social media. We check for og:title, og:description, and og:image.
- Language Attribute (5%): The lang attribute helps search engines serve your content to the right audience and improves accessibility.
Understanding Your Score
Your SEO score is calculated as a weighted average of all checks. Each factor contributes based on its importance:
- 80-100 (Green): Excellent! Your page has strong SEO fundamentals. Focus on content quality and backlinks.
- 50-79 (Orange): Good start, but there's room for improvement. Address the flagged issues to boost rankings.
- 0-49 (Red): Needs work. Multiple important elements are missing or poorly optimized. Prioritize the high-weight issues first.
Frequently Asked Questions
Is this tool accurate?
Our analyzer checks technical on-page SEO factors that are publicly visible in any webpage's HTML. While we can't access server-side factors (like page speed or crawl errors), the checks we perform are accurate and actionable for the analyzed URL.
Why can't I analyze some websites?
Some websites block automated requests or have strict security policies (CORS). If analysis fails, the target site may be unreachable, blocking our requests, or requiring authentication. Try analyzing a different page or check if the site is publicly accessible.
What's more important: score or individual checks?
Focus on individual checks, especially those marked as "fail" or "warning." A page can have a decent overall score while still missing critical elements. The specific recommendations are more actionable than the overall number.
Does this check backlinks or domain authority?
No, this tool focuses on on-page SEO factors only. Backlinks, domain authority, and off-page factors require different data sources and are outside the scope of this analyzer. We focus on elements you can directly control on your page.
How often should I check my pages?
We recommend analyzing pages after making content changes or at least monthly for important pages. SEO is an ongoing process, and regular audits help catch issues before they impact rankings.
Can I analyze competitor pages?
Absolutely! Enter any public URL to see how competing pages are optimized. This can reveal opportunities they're missing or best practices you should adopt. Competitive analysis is a great way to improve your own SEO strategy.
