Online Website Check - Complete Guide to Analysis and Optimization
A website is not a static product - it's a living organism. Every code error, missed meta tag, or slow server means lost customers. According to Google, 53% of mobile users leave a page if it takes longer than 3 seconds to load. And 68% of online experiences begin with a search engine - if your site isn't optimized, it simply won't be found. Our free tool checks 65+ parameters across 4 categories and shows exactly what needs to be fixed. For a deeper analysis, use our full website audit, and for planning a new project - the brief generator. If you need website development or business automation through CRM, ERP, or WMS - contact us for a free consultation.
Why Regularly Check Your Website
Google updates its ranking algorithms 500-600 times a year. What worked three months ago might be dragging your site to the bottom of search results today. Problems accumulate silently - a page that used to load in 1.5 seconds may slow down to 5 seconds after adding new scripts.
Regular website analysis helps identify three types of issues. First - technical errors: broken links, missing meta tags, code mistakes. Second - security vulnerabilities: no HTTPS, unprotected cookies, unsafe headers. Third - performance problems: slow loading, missing compression, incorrect cache configuration. Each of these directly affects your Google rankings and conversion rates.
SEO Analysis - What We Check and Why It Matters
Meta Tags and Headings
The title tag is the first thing a user sees in search results. If it's missing or longer than 60 characters - Google will truncate it or substitute its own. Meta description affects snippet click-through rate - a proper description can boost CTR by 30-40%. We check the presence, length, and uniqueness of both tags.
H1-H6 headings form the content structure. Google uses them to understand the page topic. Common mistakes - multiple H1 tags on a page, gaps in hierarchy (H1 directly to H3 without H2), or complete absence of headings. Our tool finds all of this automatically.
Images and Media
Images without alt tags mean lost traffic from Google Images and accessibility issues for visually impaired users. We check every image on the page and calculate the alt attribute fill rate.
Technical SEO
Canonical URLs prevent content duplication. Robots.txt controls search bot access. Sitemap.xml helps Google find all important pages. Open Graph tags affect how links appear on social media. Schema.org markup provides rich snippets in search. Hreflang ensures the correct language version for users. We check all of this in one pass and show specific recommendations for each item.
Website Security - 15 Protection Checks
Security is more than just HTTPS. The modern web requires a comprehensive approach to protection. Google Chrome marks HTTP sites as "Not Secure", and since 2014, HTTPS has been a ranking factor.
Security Headers
Content-Security-Policy prevents XSS attacks and code injections. X-Frame-Options protects against clickjacking - when your site is embedded in a frame on a fraudulent page. HSTS (HTTP Strict Transport Security) forces the browser to always use HTTPS. Referrer-Policy controls what visitor information you share with third-party sites. Permissions-Policy restricts access to camera, microphone, and geolocation.
Cookies and Data
We check three cookie flags: Secure (transmission only via HTTPS), HttpOnly (protection from JavaScript theft), SameSite (CSRF attack protection). We also analyze Subresource Integrity for external scripts - this ensures that the connected jQuery or Bootstrap hasn't been modified by an attacker.
Discovered vulnerabilities should be fixed immediately. If you need help with security configuration - contact our team. We also conduct a full website audit with a detailed report and action plan.
Loading Speed - 14 Performance Metrics
Site speed is a critical factor for both SEO and conversions. Amazon calculated that every 100ms of delay costs 1% in sales. Google included Core Web Vitals in ranking factors back in 2021.
Server Metrics
TTFB (Time to First Byte) - the time until the first byte of server response. Ideal - under 200ms. Total HTML document load time should be under 3 seconds. We also check HTML size, Gzip or Brotli compression, and HTTP protocol version (HTTP/2 is significantly faster than HTTP/1.1).
Client-Side Optimization
Render-blocking scripts and styles in <head> block page rendering. Images without specified dimensions (width/height) cause Layout Shift - elements "jump" during loading. Lazy loading for below-the-fold images saves bandwidth and speeds up initial rendering. Resource hints (preconnect, dns-prefetch) reduce connection time to external services.
When the Google PageSpeed API is available, we additionally obtain Core Web Vitals: FCP (First Contentful Paint), LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and TBT (Total Blocking Time). This is real data about your site's user experience.
Mobile Responsiveness - Why It's a Must-Have
Over 70% of traffic in Ukraine comes from smartphones. Google has switched to mobile-first indexing - this means the search bot evaluates the mobile version of your site. If your site isn't mobile-friendly - you're losing rankings regardless of content quality.
We check 6 key mobile readiness parameters. The viewport meta tag must contain width=device-width for correct scaling. Blocking zoom (user-scalable=no) is bad practice that reduces accessibility. Responsive @media rules in CSS ensure correct display on different screens. Apple Touch Icon is needed for saving the site to an iPhone home screen.
If your site isn't responsive - it's time to fix that. We build websites with responsive design by default, and for existing projects, we do complete mobile adaptation.
Common Issues and How to Fix Them
Red (Critical)
Missing HTTPS - install an SSL certificate (free Let's Encrypt or commercial). No title or H1 - add unique headings to every page. Missing robots.txt - create a file with basic rules for search bots. These issues directly affect indexing and ranking.
Yellow (Warnings)
Long title or description - shorten to recommended length (60 and 160 characters respectively). Missing Gzip compression - enable in server settings or .htaccess. No canonical URL - add the tag to prevent content duplication. These issues reduce effectiveness but don't completely block site functionality.
Prioritizing Fixes
Start with critical issues - they have the biggest impact. Then move to warnings. After fixes, run the check again - the score should improve. If you need help with the technical side - use our brief generator to describe tasks or order a full audit.
How Our Site Checker Differs from Others
Most online analyzers check either only SEO or only speed. Our tool covers 4 categories simultaneously: SEO, security, performance, and mobile readiness. This gives you the complete picture of your site's health in a single request.
- 65+ checks in 15-30 seconds
- Integration with Google PageSpeed Insights API for Core Web Vitals
- Completely free with no registration required
- Specific recommendations for each issue
- Score from 0 to 100 for each category
After the check, you'll see an overall score and details for each category. Green - everything is fine. Yellow - worth improving. Red - a critical issue that needs immediate attention. Each item includes an explanation and specific actions to fix it.
When and How Often to Check Your Site
We recommend checking your site in these situations:
- After any changes to the site - new design, plugin updates, hosting changes
- Once a month - for monitoring technical health
- Before launching an ad campaign - so you don't waste budget on a slow or broken site
- After a drop in Google rankings - to diagnose possible causes
- When launching a new project - to make sure everything is configured correctly
If you're planning a new website or automation system - CRM, ERP, HRM, or WMS - it's important to lay the right technical foundation from the start. Use our cost calculator for a preliminary estimate or contact us for a consultation.
