Optimize images & assets
Optimization Tips
- Compress images: Use WebP format and proper sizing
- Minify CSS/JS: Remove unnecessary whitespace and comments
- Enable caching: Set proper cache headers for static resources
- Use a CDN: Distribute content globally for faster delivery
- Lazy load images: Load images only when they enter viewport
Core Web Vitals (2025 Standards)
Google uses Core Web Vitals as ranking signals. These metrics measure real-world user experience:
LCP
Largest Contentful Paint
Measures loading performance. Time until the largest content element becomes visible.
INP
Interaction to Next Paint
Measures responsiveness. Time from user interaction (click, tap) to visual response.
CLS
Cumulative Layout Shift
Measures visual stability. Sum of all unexpected layout shifts during page load.
Why Core Web Vitals Matter
Google officially confirmed that Core Web Vitals are ranking factors. Pages with good Core Web Vitals scores have better chances of ranking higher in search results, especially for mobile searches.
SEO Elements Analysis
We analyze critical on-page SEO elements that directly impact your search rankings:
Title Tag
The <title> tag is the most important on-page SEO element. It appears in search results and browser tabs.
Best Practices:
- • Length: 50-60 characters (avoid truncation in SERPs)
- • Include primary keyword near the beginning
- • Make it compelling and clickable
- • Include brand name at the end (optional)
- • Each page should have a unique title
Meta Description
The meta description appears below your title in search results. While not a direct ranking factor, it heavily influences click-through rates.
Best Practices:
- • Length: 150-160 characters optimal
- • Include target keywords naturally
- • Write compelling copy with call-to-action
- • Accurately describe page content
- • Make each description unique
Headings Structure (H1-H6)
Proper heading hierarchy helps search engines understand content structure and improves accessibility.
Best Practices:
- • Use exactly one H1 per page (main topic)
- • Follow logical hierarchy: H1 → H2 → H3
- • Don't skip levels (H1 → H3 is bad)
- • Include keywords in headings naturally
- • Make headings descriptive and scannable
Canonical URL
The canonical tag tells search engines which version of a page is the "master" copy when duplicate content exists.
When to Use:
- • Multiple URLs showing same content (www vs non-www)
- • Product pages with URL parameters
- • Printer-friendly versions of pages
- • Content syndication
Security Headers Analysis
Security headers protect your website and users from common web vulnerabilities. We check for 10+ critical headers and provide a security score (0-100).
Content-Security-Policy
Prevents XSS attacks by controlling which resources can be loaded
Strict-Transport-Security
Forces HTTPS connections, preventing downgrade attacks
X-Frame-Options
Prevents clickjacking by controlling iframe embedding
X-Content-Type-Options
Prevents MIME type sniffing attacks
Security Score Interpretation
Most security headers properly configured
Some important headers missing
Critical headers absent, immediate action needed
Links & Images Analysis
Link Analysis
-
Internal Links: Links to other pages on your site (helps SEO and navigation)
-
External Links: Links to other websites (verify quality and relevance)
-
Broken Links: We detect 404 errors and unreachable URLs
Image Optimization
-
Alt Text: Critical for accessibility and image SEO (describe images for screen readers)
-
File Size: Large images slow down page load (compress without losing quality)
-
Modern Formats: Use WebP or AVIF for better compression

How much does PerSeo Insights cost?
PerSeo Insights is currently completely free for all users! Both guest and registered accounts can perform SEO analysis at no cost.

What does "ALPHA" version mean?
We're in active development! "Alpha" means we're continuously adding new features, improving existing ones, and fixing bugs. You may encounter occasional issues or see features change. We appreciate your feedback to help us improve! Report bugs or suggestions.
Is my data safe?
Yes! We take data protection seriously and are fully GDPR compliant. We store only essential data (email, hashed passwords), never share it with third parties, and you can request data deletion at any time. All passwords are encrypted using bcrypt. Read our Privacy Policy for details.
Can I analyze any website?
Yes, you can analyze any publicly accessible website. PerSeo Insights fetches publicly available data using a combination of direct HTTP requests, third-party APIs (like Google PageSpeed Insights), and our proprietary analysis algorithms. We don't access password-protected content or private areas. Our analysis respects robots.txt and website terms of service.
Why are there scan limits?
PerSeo Insights is a completely free service. To keep it that way and ensure fair access for everyone, we implement daily scan limits to manage server resources and prevent abuse. Registered users get 5 single URLs + 5 sitemaps per day, while guests can perform 1 single URL + 1 sitemap per day. If you need higher limits, please contact us.
Can I see my previous scans?
Scan history is currently in development! Registered users will soon be able to view all their past analyses, compare results over time, and track SEO improvements. This feature will be rolled out in an upcoming update. Follow our changelog for announcements.
Will there be an API?
Yes! A REST API is planned for future releases, allowing developers to integrate PerSeo Insights into their own applications, CI/CD pipelines, or monitoring systems. API access will likely be part of a Premium tier. Express your interest to help us prioritize development.
Is there a mobile app?
Yes! An Android app is currently in development and will be released soon. However, you can already use PerSeo Insights from your mobile device right now - our platform is fully responsive and optimized for mobile browsers, providing a seamless experience on smartphones and tablets.
