Learn how to read and improve your SEO Score, Core Web Vitals, and Domain Power
Positioning
SEO_CHECK takes a different approach from existing SEO and analytics tools. Instead of just diagnosing issues, it goes all the way to auto-generating fix code — a hands-on tool built for web developers, freelancers, and site owners.
Ahrefs / Semrush / Moz
Backlink analysis, rank tracking, large-scale crawling. $99+/mo. SEO_CHECK does not analyze backlinks
Keyword Research Tools
Dedicated keyword research. SEO_CHECK's keyword features are supplementary
Google Analytics
Traffic analytics (sources, behavior, conversions). SEO_CHECK diagnoses site quality, not traffic volume
Google Search Console
Search performance (impressions, CTR, ranking). SEO_CHECK is the "prescription" to check after GSC
SEO Cheki
Free basic checker. SEO_CHECK goes further with auto-generated fix code on top of diagnosis
SEO score diagnosis → prioritized improvement points → auto-generated fix code for structured data and meta tags. Other tools find problems, but you still need to figure out the exact code changes. SEO_CHECK outputs the code for you.
Enter the URL of the website you want to check in the input field

Score Breakdown
Presence and accuracy of JSON-LD, Schema.org type detection, required property coverage, and Rich Results eligibility
Properly configured structured data enables Rich Results in Google (star ratings, FAQs, breadcrumbs, etc.), significantly improving click-through rates
Use JSON-LD format with Schema.org vocabulary and set the appropriate type (Article, FAQPage, Product, etc.) for your page. Verify with Google's Rich Results Test tool
Title tag (30-60 characters recommended), meta description (120-160 characters), heading hierarchy (H1-H6), canonical tag, and OGP tags
Title and meta description are displayed directly in search results. Proper optimization improves both rankings and click-through rates
Set a title with target keywords within 30-60 characters and write a unique meta description for each page. Use only one H1 per page
Text volume (1,000+ characters recommended), image alt attribute coverage, and internal/external link counts
Sufficient text helps Google understand your page content. Alt attributes affect image search, and links boost overall site authority
Create quality content with 1,000+ characters, add alt attributes to all images, and include internal links to related pages
HTTPS compliance, mobile-friendly design, page speed, and security headers (HSTS, etc.)
Without proper technical foundations, search engines cannot crawl and index your content effectively, regardless of content quality
Enable HTTPS, implement responsive design, and optimize page speed through image compression and CSS/JS minification
Three key metrics defined by Google to measure user experience quality. These are also Google search ranking factors
Measures the time until the main content of the page is displayed. This is how fast users perceive the page has loaded
💡 Optimize images (WebP format, lazy loading), improve server response times, and minimize CSS/JS
Measures how much the page layout shifts during loading. Evaluates unexpected movement caused by images, ads, or banners loading
💡 Specify dimensions for images and videos in advance, and prevent layout shifts from web font loading
Measures the time from user interaction (like button clicks) until the screen responds with a visual update
💡 Split heavy JavaScript tasks, avoid blocking the main thread, and reduce unnecessary scripts
A comprehensive score from 0-100 based on LCP, CLS, INP and other metrics. 90+ is considered good
Mobile and desktop are measured separately. Mobile scores tend to be lower. Since Google uses mobile-first indexing, prioritize mobile improvements
A score from 0-10 indicating how much trust search engines place in your domain. Higher scores mean new pages are more likely to rank well
Newly launched site with few backlinks and limited trust established with search engines
Content accumulation and backlink acquisition are progressing. Consistent operation is key
A site with established credibility. Quality content and natural backlinks are being recognized
Industry-leading trust level. Typically major media outlets and government organizations
The number of years since the domain was registered. Domains operated for longer periods are generally considered more trustworthy
A comprehensive tool for SEO keyword research: bulk suggest keywords, monthly search volume, and ranked keyword analysis — all in one place.
Fetch Google suggest keywords in bulk for any keyword. Paid plans also display monthly search volume, CPC, and competition. Click column headers to toggle sort order.
Monthly search volume shows the average monthly Google searches. Values use Google Ads standard rounding (590, 720, 880, 1000, 1300, etc.). CPC is the cost per ad click, and competition (0-1) indicates advertising competition level.
Enter a domain to see which keywords it ranks for on Google. View ranking position, monthly search volume, CPC, and competition to discover your site's strengths and improvement opportunities.
Compare SEO scores and Domain Power side by side with competitors. Helps identify gaps and prioritize improvements
