Holistic SEO Prioritisation for LLMs and Search

SEO, accessibility, page speed, security and AI-crawler auditing - with everything ranked on one holistic priority list, not scattered across separate tools. Built for B2B, events, trades, and service businesses running lead-gen sites, where quality beats scale.

🎯 The problem

🔧 A plugin updates, a page gets edited, a redirect breaks
♿ An accessibility fix gets reverted by a theme change
🔓 A security header gets dropped during a server change
😬 Nobody notices until it costs something - rankings, a complaint, a missed enquiry, an exposed file
✅ Crawley notices automatically, on a schedule, and says exactly what changed

🎯 One holistic priority list

👍 To be fair to the others: SEMrush already buckets issues into Errors/Warnings/Notices with "why and how to fix it" guidance, and Screaming Frog now tags issues with type and estimated priority too
🧩 What stays siloed: that prioritisation only ranks issues within whichever one category that tool owns - SEO against SEO, accessibility against accessibility
🎯 Crawley's METRIC score ranks everything found - SEO, WCAG, security, AI-readiness - against each other in one single, holistic queue, so a broken quote-request form and a missing alt tag get weighed on the same scale
💡 Every issue ships with a plain-English "why it matters," a concrete fix, and a difficulty/time estimate - not just a severity label

👥 Who it's for

✅ Good fit

Smaller, focused sites - roughly under 500 pages, where quality beats raw scale
B2B, events, trades, and service businesses - primarily lead-gen sites where every page needs to convert an enquiry
Every page gets crawled - no page cap, discovered via your sitemap and (WordPress) a direct database read so nothing gets missed
Agencies & in-house teams on WordPress, Drupal, Joomla, Craft, or custom PHP/HTML
No file access on your platform? External mode covers Shopify, Wix, Squarespace, Webflow, and any other fully-hosted platform too - discovery via sitemap.xml/robots.txt/llms.txt instead of an installed agent
Want ongoing monitoring without hiring a dedicated technical SEO person

❌ Not a good fit

Very large e-commerce catalogues - every page still gets checked, but PageSpeed's own external API is the bottleneck, so only your configured depth (5–25 pages) gets full Core Web Vitals data each run
Large or enterprise-scale sites - thousands of pages will take a while to work through one PageSpeed segment at a time; SEO/WCAG/security checks still cover everything, just not instantly
Deep manual crawls of 10,000+ URLs - that's Screaming Frog's job
Keyword research, backlinks, content strategy - that's SEMrush/Ahrefs territory

🤖 AI assistants - a fast-moving gap

General AI assistants have gotten genuinely good at explaining SEO/accessibility concepts and drafting fixes
What's still missing industry-wide: a persistent connection to your actual live site - real Lighthouse numbers, real response headers, memory of what changed last week
That's the gap Crawley sits in - an installed agent does the measuring, and the Claude connector lets you ask about the results in plain English

🐸 Desktop crawlers - expanding fast

Screaming Frog has grown a lot in recent versions - AXE-based accessibility auditing, security header checks, its own crawl scheduling
The underlying model hasn't changed: locally-run, per-user licensed software, exporting data you interpret yourself
Crawley sits at the cloud-hosted, always-on end of that same spectrum - trading some raw crawl depth for continuous monitoring and one unified score

📈 SEO suites - broadening into new categories

SEMrush and Ahrefs have both added AI-search/GEO categories, and accessibility scanning via a bolt-on app
Their core is still built around content and link strategy, not fine-grained technical/security health
Crawley sits in that narrower technical lane - meant to sit alongside a SEMrush/Ahrefs subscription, not replace it

📝 WordPress SEO plugins (Yoast, etc.) - moving fastest on AI

Yoast writes some of the best in-editor guidance around - readability, keyphrases, schema, canonical URLs and XML sitemaps handled as you publish
Its AI-readiness tooling has moved genuinely fast - Bot Blocker (toggle GPTBot, CCBot, Google-Extended access), Schema Aggregation, and an automatic llms.txt
Different job though: Yoast optimises content at write-time from inside WordPress. It doesn't run a scheduled external audit of the live rendered page, its "accessibility" help is writing tips rather than a WCAG technical check, and it's WordPress-only
Crawley sits downstream of it - Yoast shapes what you publish; Crawley checks what actually shipped, on a schedule, across whichever CMS you run

✅ What Crawley actually checks

📅 Automated crawls of your entire live site - every page, no cap
🔍 SEO, WCAG accessibility, page speed, and Core Web Vitals
🔒 Security headers, exposed sensitive files, and directory listing checks
🤖 AI-crawler / LLM-readiness checks
♻️ Regression detection - tells you if a fix didn't actually stick
📋 Prioritised fix checklist and a full trend history

⚠️ Worth knowing: PageSpeed's own external API is slow (10–25s per page), so only a configurable subset (5–25 pages) gets full Core Web Vitals data each run - everything else still gets SEO/WCAG/security checked. And even a full crawl is pattern-matching, not a substitute for manual review.
