SEOControl – Free SEO, GEO & AI Website Audit

SEOControl is a free online tool for website analysis. It performs over 60 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.

What we analyze

Our audit covers six main categories. Each category contains multiple individual checks. Every check produces a score from 0 to 100.

Meta tags and content

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

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.

Technical SEO

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 readiness

AI search engines are changing how people find information. GPTBot crawls websites for ChatGPT. Google-Extended does the same for Gemini. We check if your robots.txt allows these crawlers. 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.

Security

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.

Local and GEO SEO

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.

How it works

  1. Enter your URL — paste any website address into the form. Both HTTP and HTTPS URLs are accepted.
  2. Automatic analysis — SEOControl crawls the page in real-time. All 60+ checks run simultaneously. The process takes under 30 seconds.
  3. Get your report — you receive an overall score from 0 to 100. Each check shows its own score and status. Failed checks include specific fix recommendations.

Understanding your SEO score

The overall score ranges from 0 to 100 points. Scores above 80 indicate good optimization. Scores between 50 and 80 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.

Real-world SEO data and benchmarks

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.

Example: typical audit findings

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.

Common SEO mistakes we detect

Missing title tags are the most critical error. We find them on 12% of audited sites. Duplicate meta descriptions appear on 35% of multi-page sites. Missing alt text on images affects 68% of websites. Broken internal links appear on 23% of sites.

Security issues are surprisingly common. About 8% of sites still serve mixed HTTP/HTTPS content. The X-Powered-By header leaks technology info on 45% of PHP sites. Missing HSTS headers affect 60% of otherwise secure sites. Each of these is a quick fix.
