SEOControl is a free online tool for website analysis. It performs over 80 checks across SEO, GEO and AI categories. You get specific recommendations to improve visibility in search engines. The tool also checks readiness for AI systems like ChatGPT, Gemini and Perplexity.
Most websites never receive organic traffic from Google. According to Ahrefs, 96.55% of pages get zero search visits. Technical SEO issues are often the main reason. Missing meta tags, broken redirects and poor structured data prevent indexing. SEOControl identifies these problems quickly and gives you a clear action plan.
Our audit covers six main categories. Each category contains multiple individual checks. Every check produces a score from 0 to 100.
We check your title tag length and uniqueness. The meta description is analyzed for length and keyword presence. Open Graph tags are verified for Facebook and LinkedIn sharing. Twitter Card tags ensure proper display on X (Twitter). We also verify heading hierarchy from H1 to H6.
Structured data helps search engines understand your content. We validate Schema.org markup in JSON-LD format. This includes Organization, Article, FAQ, HowTo, BreadcrumbList and LocalBusiness schemas. Rich snippets in Google depend on correct structured data. We check all required and recommended properties.
HTTPS enforcement is checked first. We verify www to non-www redirects (or vice versa). The sitemap.xml is validated for proper format and accessibility. Robots.txt rules are analyzed for crawling issues. Hreflang tags are checked for multilingual sites. Canonical URLs prevent duplicate content problems.
AI search engines are changing how people find information. GPTBot crawls websites for ChatGPT model training, while OAI-SearchBot, Claude-SearchBot and PerplexityBot power AI search and citations. We check both groups in your robots.txt: blocking training bots is your choice, but blocking search bots removes your site from AI answers. E-E-A-T signals (Experience, Expertise, Authority, Trust) are verified. Author information and publication dates improve AI citations. Content structure is analyzed for direct answer suitability.
HTTPS is mandatory for modern websites. We check HSTS headers for transport security. Server version headers are flagged as security risks. X-Powered-By headers reveal technology stack unnecessarily. Content Security Policy headers protect against XSS attacks. Each security issue is rated by severity.
For local businesses, NAP data (Name, Address, Phone) is essential. We check LocalBusiness schema markup. Geo meta tags help with regional targeting. Google Business Profile signals are verified. These checks are critical for businesses serving local customers.
The overall score ranges from 0 to 100 points. Scores of 90 and above indicate good optimization. Scores between 50 and 89 need improvement. Scores below 50 have critical issues to fix. The score is weighted by check importance. Critical checks like HTTPS and meta tags weigh more.
Each check uses a traffic light system. Green means passed (80-100). Yellow means warning (50-79). Red means failed (0-49). Focus on red items first for the biggest impact.
Understanding industry benchmarks helps set realistic goals. According to Backlinko, the average first-page result on Google has 1,447 words. Pages with meta descriptions get 5.8% more clicks than those without. Title tags between 15-40 characters have the highest CTR.
Semrush research shows that 25.02% of top-ranking pages have no meta description at all. Google rewrites meta descriptions 62.78% of the time. Despite this, writing good descriptions still matters for CTR. Pages using structured data see a 30% higher click-through rate in search results.
For AI readiness, Search Engine Land reports that AI Overviews appear in 47% of Google searches. Content with clear E-E-A-T signals gets cited 3x more often. Pages with FAQ schema are 2.5x more likely to appear in AI answers. Author bylines and publication dates are now ranking factors for AI systems.

| AI Visibility | AI bot access, llms.txt, content structure, Bing index |
Here is what a typical audit reveals for an average small business website. The site scores 45/100 overall. Title tag is present but too long at 78 characters — optimal is 50-60. Meta description is missing entirely. No Open Graph tags means social sharing shows a blank preview. The site uses HTTP with no redirect to HTTPS. No structured data of any kind is present. Images lack alt text. The robots.txt file blocks the sitemap accidentally.
After fixing these issues based on SEOControl recommendations, the same site scores 82/100. The title is trimmed to 55 characters. A compelling meta description is added. Open Graph and Twitter Card tags generate rich previews when shared. HTTPS is enforced with a 301 redirect. Organization and LocalBusiness JSON-LD schemas are added. All images receive descriptive alt text. The robots.txt is corrected and a sitemap.xml is submitted.
A missing or overly long title tag is among the most serious errors, because the title is the headline of your search result. Other frequent findings are missing meta descriptions, images without alt text, broken internal links and pages accidentally blocked by noindex or robots.txt.
Security basics are often overlooked too: HTTP resources on an HTTPS page (mixed content), a missing HSTS header, or server headers that reveal software versions. Each of these is usually a quick fix.
Website owners use it to monitor site health. SEO consultants run audits for client reports. Web developers check technical quality. Content creators verify search guideline compliance. Marketing teams track SEO progress over time. E-commerce stores optimize product pages for better rankings.
The tool works for any website. It supports single-page applications, static sites and server-rendered pages. WordPress, Shopify, Wix and custom-built sites all work equally well.
SEOControl is built with modern web technologies. The backend uses Symfony framework for PHP. The frontend uses React with TypeScript. Audits run server-side for accurate results. We follow Google Search Central guidelines for all checks.
Our methodology is based on official documentation from Google, Moz, and web.dev. Each check references the specific guideline it validates. Recommendations include links to relevant documentation.
