Tools for the AI era
Tools from the blicht editorial practice: fast, free, no sign-up. Each one covers its field completely and tells you how to fix every red finding – honestly including the cases where something cannot be tested automatically.
Visibility & SEO
Technical SEO Check
Tests a page against the technical SEO fundamentals – indexability, canonical, redirects, head tags, structured data and real web vitals. With a fix guide per finding.
Website Crawl (10 pages)
Pulls your sitemap and checks up to 10 pages – for shops including home, category and product. Finds duplicate titles, leftover noindex tags, dead sitemap entries and canonical inconsistencies.
Structured Data Check
Checks structured data for more than validity: missing required fields, unused shipping and returns data, and markup that would suit the page.
AI & agents
LLM Brand Check
Asks a current language model what it knows about your brand or domain – awareness, positioning, recommendation contexts.
Agent-Ready Check
Tests your website against the open standards of the agentic web – robots.txt, llms.txt, markdown negotiation, MCP & co. With a fix guide per finding.
Tech & law
Email Deliverability Check
Reads your domain's mail records: SPF including the 10-lookup limit, DKIM, DMARC, MX, MTA-STS, TLS reporting and DNSSEC – with a fix guide per finding.
Accessibility Check
Finds the WCAG barriers that are reliably detectable in markup: missing alt text, unlabelled form fields, broken headings, blocked zoom – each with its success criterion.
Cookie & Tracker Check
Shows which third parties and cookies load before any consent – with provider name, category, location and an assessment of whether consent is required.
