Every tool your SEO workflow actually needs
This hub covers the full breadth of on-page and technical SEO tooling — from generating and validating meta tags, to previewing how your pages appear in Google SERPs, to auditing canonical tags at scale, to producing schema markup and XML sitemaps without touching code. All 20 tools are free and require no account or login.
Built for the modern SEO stack: Whether you're doing a site audit, launching new content, diagnosing indexing issues, or preparing structured data for AI search visibility, these tools cover the tasks that come up every week in real SEO work — not just the headline features that get demoed at conferences.
20 Website & SEO Tools
Each tool is purpose-built for a specific SEO task. No bloat, no gated features — just the output you need.
SEO Auditor
A comprehensive on-page SEO audit for any URL — analysing title tags, meta descriptions, heading structure, canonical tags, Open Graph data, image alt attributes, internal links, page speed indicators, and structured data presence. The best starting point for any site review: it surfaces the issues that the individual tools in this hub can then help you fix one by one.
AI Meta Tag Generator
Generate optimised title tags and meta descriptions using AI — paste in your page content or URL and get SEO-ready suggestions that respect character limits and target keyword placement. Ideal for scaling meta tag production across large content libraries.
Meta Tag Generator
Build complete, standards-compliant meta tag sets for any page — title, description, keywords, robots directives, Open Graph, and Twitter Card tags — with a form-based UI and instant copy-ready HTML output. No coding knowledge required.
Title Tag Optimizer
Analyse and optimise your title tags — checks pixel width (not just character count), keyword placement, brand suffix format, and common truncation issues. Get a score and specific rewrite suggestions for titles that underperform in SERPs.
Meta Description Checker
Check any live URL's meta description — length, character count, keyword presence, and whether it's likely to be rewritten by Google. Flags missing, duplicate, or over-length descriptions and provides rewrite guidance.
Open Graph Tag Generator
Generate complete Open Graph and Twitter Card meta tag sets for any page — including og:title, og:description, og:image, og:type, and all required Twitter Card properties. Copy the HTML block directly into your page head.
SERP Simulator
Preview exactly how your page will appear in Google desktop and mobile search results — including title, URL, and meta description with real truncation rendering. Spot truncation issues before they appear in live SERPs.
Keyword Density Checker
Analyse keyword frequency and density across any page or pasted text — identifies over-optimisation risks, surfaces the most prominent terms, and shows 1-, 2-, and 3-word phrase frequencies. Useful for content audits and competitive benchmarking.
Duplicate Content Checker
Check for duplicate or near-duplicate content between two URLs or text blocks. Highlights sentence-level similarities and provides a similarity score — essential for identifying thin content, scraped copies, and internal duplication issues that harm crawl efficiency.
Schema Markup Generator
Generate valid JSON-LD schema markup for common schema types — Article, LocalBusiness, Product, FAQ, HowTo, BreadcrumbList, and more — through a guided form interface. Paste the output directly into your page head or CMS.
Robots.txt Generator
Build a valid robots.txt file through a visual UI — configure allow/disallow rules per user-agent, set crawl delay, and link to your XML sitemap. Prevents common misconfiguration errors that accidentally block Googlebot from crawling entire site sections.
XML Sitemap Generator
Crawl a domain and automatically generate a standards-compliant XML sitemap — with configurable priority, change frequency, and lastmod values. Submit the output directly to Google Search Console or host it at /sitemap.xml.
Sitemap Validator
Validate any XML sitemap against sitemap protocol standards — checks for malformed XML, invalid URLs, incorrect date formats, missing required elements, and URLs that return non-200 status codes. Use before submitting to Google Search Console.
Sitemap Extractor
Extract and list all URLs from any XML sitemap or sitemap index — including nested sitemaps — and export as a flat CSV or plain-text list. Useful for competitor research, content audits, and redirect mapping during migrations.
Canonical URL Generator
Generate the correct canonical link element for any URL — normalising protocol, trailing slash, and parameter handling according to your preferred configuration. Copy the ready-to-paste HTML tag directly into your page head.
Bulk Canonical Checker
Paste a list of URLs and check the canonical tag returned by each — whether it's self-referencing, pointing elsewhere, or missing entirely. Flags canonicalisation conflicts at scale without needing a paid crawler subscription.
Anchor Text Analyzer
Analyse the anchor text distribution of any page's internal and external links — identifies over-optimised exact-match anchors, missing generic anchors, and the ratio of branded to non-branded link text. Essential for link profile audits and penalty risk assessment.
Backlink Generator
Generate a curated list of high-quality directories, resource pages, and citation sources relevant to your niche — streamlining the prospecting phase of link building campaigns. Outputs categorised link targets with domain authority indicators.
Website Down Checker
Instantly check whether a website is down for everyone or just for you — tests the URL from an external server and returns HTTP status, response time, and whether the site is reachable globally. Useful for quick triage before escalating to your hosting provider.
WordPress Theme Detector
Identify the WordPress theme and active plugins used by any website — including theme name, version, author, and child theme status. Useful for competitive research, client discovery, and quickly replicating site setups you admire.
Common SEO scenarios these tools solve

Before going live: generate your XML sitemap, validate it, check robots.txt, verify canonical tags across key pages, and confirm your Open Graph tags render correctly in social previews.
Link Builders
Use the Anchor Text Analyzer to audit your current link profile before a campaign, and the Backlink Generator to surface initial prospect targets by niche.
