CrawlCheck vs Keywords Everywhere: Which Is Better in 2026?

CrawlCheck is a free GEO (generative engine optimization) audit tool that shows exactly how AI crawlers see your website. Paste any domain and get an instant report: which of 61 AI crawlers are allowed, blocked, or ignored by your robots.txt, whether your llms.txt file exists and is well formed, and whether your sitemap is healthy and discoverable.

AI search is becoming a real traffic source. Chatbots like ChatGPT, Claude, Perplexity and Google AI Overviews fetch pages before they answer, and they obey very different rules from Googlebot. A robots.txt that looks fine for classic search can silently lock out GPTBot, ClaudeBot, PerplexityBot or Google-Extended, which means your content never enters the index behind those answers.

CrawlCheck checks all of this in one scan. You get a per-crawler breakdown that separates allowed, blocked and ignored agents, a check on your llms.txt and sitemap, and a short list of concrete fixes ordered by impact. Every scan produces a shareable report link you can send to a client, a developer or your team, so the fix list turns into a work item instead of a vague warning.

The report flags the exact user-agent lines that are missing or disallow rules that are too broad, points out a missing or malformed llms.txt, catches sitemap errors such as blocked entries or a stale lastmod, and gives copy-paste snippets for the most common setups, including Cloudflare, Next.js, WordPress and plain static hosting. Each finding is labelled with a severity level so you can fix the blockers first and leave the cosmetic items for later.

The tool is built for SEO teams, content marketers, developer-facing SaaS founders and indie makers who want their pages to be cited by AI search engines, not just ranked by classic search. It runs on Cloudflare Workers, needs no account, and returns results in a few seconds. Visit crawlcheck.dev to run a free audit on your own site.

What problem it solves

A robots.txt that looks fine for Googlebot can silently lock out GPTBot, ClaudeBot, PerplexityBot and Google-Extended, so your content never enters the index behind AI answers.

Alternatives & competitors

Manual robots.txt checkers, Screaming Frog, and generic SEO audit tools that do not model individual AI crawler user-agents.

Keywords Everywhere is a browser extension that layers marketing and SEO data directly onto the websites you already visit. Instead of jumping between separate research tools, you see search volume, cost-per-click, competition and more right inside Google, YouTube, Amazon and a dozen other platforms — turning ordinary browsing into keyword and market research.

What is Keywords Everywhere?

Keywords Everywhere is a Chrome and Firefox add-on used by over 1.5 million marketers (including teams at Adobe, Netflix, Forbes and Salesforce). As you search and browse, it surfaces the metrics you'd normally have to look up in a dedicated SEO suite — keyword volumes, CPC, competition, related terms, traffic estimates and backlink data — in context, on the page you're already on.

Who it's for

The extension is built for SEO specialists, content creators, e-commerce sellers, social media managers and marketing professionals of every level. Anyone who does keyword research, plans content, or sizes up a market — whether for Google, YouTube or a marketplace like Amazon — can get value from having the data appear as they work rather than in a separate tab.

Key features

• Search volume, CPC and competition across 15+ platforms
• Website traffic estimates, domain authority and backlink data (via Moz)
• Social insights for Instagram, Pinterest and Twitter/X, plus YouTube analytics
• 200+ AI prompt templates for ChatGPT, Claude, Gemini and DeepSeek
• E-commerce keyword research for Amazon, eBay and Etsy
• Competitor keyword discovery and backlink metrics
• Historical search-volume trends

Research where you already are

The core appeal of Keywords Everywhere is passive, in-context insight. Rather than opening a research tool, exporting a list and switching back and forth, you simply surf — and the data appears on Google searches, YouTube results, Amazon listings and Google Trends as widgets and overlays. That "insights as you browse" model saves the constant context-switching that eats into keyword and competitor research.

Broad platform coverage

Keywords Everywhere isn't limited to Google. It pulls metrics across Bing, YouTube, Amazon, eBay, Etsy, Google Trends, Search Console, Instagram, Pinterest and Twitter/X, so a single extension covers SEO, e-commerce and social research in one place. For sellers and social managers especially, having marketplace and platform metrics inline is a meaningful shortcut over piecing them together manually.

Fair, flexible pricing

Keywords Everywhere runs a freemium model: 18 features — including traffic metrics, link data, keyword widgets and the AI prompt templates — are permanently free, while paid credits unlock search volume, CPC, competition and historical trends. You buy credits as you need them with annual options and easy cancellation, which makes it far cheaper than a full enterprise SEO suite for people who just want the numbers on demand.

Built for the AI search era

Keywords Everywhere has leaned into how research is changing. It ships 200+ prompt templates for ChatGPT, Claude, Gemini and DeepSeek, so you can move from raw keyword data straight into AI-assisted content work, and it offers MCP server support to feed live data into AI assistants. For marketers whose workflow now runs through AI tools, having real search metrics and ready-made prompts in the same place is a genuine head start.

Why choose Keywords Everywhere

For marketers who want SEO and market data without the cost and overhead of a heavyweight platform, Keywords Everywhere is a smart, low-friction tool. Its in-browser metrics, wide platform coverage, AI prompt library and pay-for-what-you-use pricing make it one of the easiest ways to fold real keyword and competitor data into everyday work.
