Professional SEO analysis tools: audit your website for free
The Jerrejerre SEO 360° Route combines four web analyzers that audit the technical pillars Google evaluates to rank your site. Each tool works on the HTML the crawler receives, not the source code, so the diagnosis reflects what Google actually sees.
Visibility
SEO analyzer: audit your search engine visibility
Run a complete on-page SEO analysis of the factors that determine whether Google can crawl and index your content. Checks title and meta description tags, H1–H6 heading hierarchy, Schema.org structured data, canonical URLs and robots directives. Detects keyword cannibalization between pages and duplicate content that dilutes your domain's SEO authority.
Speed
Web performance analyzer and Core Web Vitals monitor
Measures the Core Web Vitals metrics Google uses as a ranking signal: Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS). Also evaluates Time to First Byte (TTFB) and render-blocking resources. A site that loads in under 2.5 seconds retains up to 32 % more users and directly improves its organic search ranking.
Inclusion
Accessibility analyzer: WCAG 2.1 compliance checker
Evaluates compliance with WCAG 2.1 guidelines (levels A and AA), the international web accessibility standard. Checks color contrast, alt attributes on images, keyboard navigation and ARIA roles. Google treats accessibility as a quality signal: an accessible site improves organic rankings and extends your reach to all users, including people with disabilities.
Structure
Visual stability evaluator and layout consistency checker
Analyzes layout stability during page load to detect unexpected visual shifts that affect CLS (Cumulative Layout Shift). Identifies elements without declared dimensions, web fonts causing FOUT or FOIT, iframes without reserved space and third-party scripts that block rendering. A stable visual experience reduces bounce rate and directly improves Google's mobile ranking.
From SEO to GEO
Already optimized your technical SEO? The next step is Generative Engine Optimization (GEO): the discipline that adapts your content to be cited by AI-powered search engines like ChatGPT, Gemini and Perplexity. Our team combines professional SEO auditing with GEO strategy so your site gains visibility on Google and on generative answer engines.
