Free SEO Tools
Every one of them runs without an account, a credit card or an upload limit. Built for the checks we needed ourselves.
Schema Markup Generator
Build valid JSON-LD for Article, FAQ, How-to, Product, Local Business, Breadcrumbs, Organization and Video — with the fields Google actually requires marked.
Open toolrobots.txt & Sitemap Checker
Tests robots.txt, validates sitemap.xml, and finds the pages your own robots.txt blocks — the conflict neither file shows on its own.
Open toolAI Tweet Rewriter
Rewrites a draft tweet through a fixed playbook: numbered hooks, basic English, reply magnets.
Open toolAI Crawler Access Checker
Shows which AI crawlers your robots.txt lets in — GPTBot, ClaudeBot, PerplexityBot, Google-Extended — and what blocking each one costs you.
Open toolSERP & Social Preview
Shows how your title, description and OG tags render in Google and on social, with length limits flagged.
Open toolKeyword Density & Readability
Counts term frequency and scores readability, so you can see stuffing and heavy sentences before you publish.
Open toolBroken Link Checker
Crawls a page and reports every link that 404s or redirects, with the status code for each.
Open toolSpam Risk Checker
Scores a page against the patterns Google’s spam policies describe, and names what triggered each one.
Open toolChecking is the easy half.
Bold Pilot checks every keyword against its live results page, writes the article, and publishes it — week after week.
