What is CrawlCheck?

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.

What is EmailOctopus?

Email marketing platforms have a nasty habit of getting more complicated and more expensive the more successful your list becomes. EmailOctopus is the antidote: a focused, affordable email marketing platform that does the important things well without burying you in features you'll never touch. Its motto — 'email marketing made easy' — is refreshingly honest.

Build campaigns without the fuss

EmailOctopus gives you an intuitive drag-and-drop editor for building emails with images, video blocks and even custom code, so you can create campaigns that feel authentic and tailor-made rather than stiff and templated. The whole experience is designed around simplicity — you spend your time writing good emails, not decoding a convoluted interface. For creators and small teams, that ease is a genuine relief.

Automation and smart targeting

Despite the simplicity, EmailOctopus isn't underpowered. It offers automation for welcome sequences and subscriber workflows, segmentation through tags so you send the right message to the right people, and dynamic personalization of subject lines and content to make each email feel one-to-one. You can schedule sends and lean on detailed reporting to see what's landing, and it connects to over 1,000 apps to fit your stack.

Deliverability you can count on

An email tool is only as good as its ability to actually reach the inbox, and EmailOctopus emphasizes strong deliverability — the unglamorous but crucial factor that determines whether your campaigns get seen or spam-foldered. That focus is a big reason cost-conscious senders trust it with their lists.

Affordable at scale

The pricing is a headline feature in itself: EmailOctopus is markedly cheaper than many incumbents, which matters enormously once your list grows into the tens of thousands. Not being punished financially for building an audience is the whole point.

Who it's for

EmailOctopus suits small to medium-sized businesses, newsletter creators, real-estate professionals, ecommerce operators, affiliates and authors — anyone who wants a straightforward, cost-effective email marketing solution without the enterprise bloat.

Pricing

EmailOctopus uses usage-based pricing scaled by subscriber count (monthly or yearly, with about 10% off annually), and there's a free tier with no credit card required. As an example of the value, around 100,000 subscribers costs roughly $480/year — a fraction of what some competitors charge at that scale.

Bottom line: EmailOctopus is the simple, affordable email marketing platform for people who want great campaigns and solid deliverability without the complexity or the ballooning bill — especially as their list grows.
