Changelog

Every feature, improvement, and fix — shipped in the open. Updated with every release.

v1.4.0 Latest June 2026

Our biggest release yet — LLM citation scoring arrives, Schema auto-generation goes live, and the report dashboard gets a full redesign for faster triage.

New
  • LLM Citation Score — a new 0–100 metric measuring how likely an AI model is to cite your page in a conversational answer
  • Schema Auto-Generator — paste any page URL and get ready-to-copy JSON-LD output for Article, Product, FAQPage, and BreadcrumbList types
  • Competitor Benchmark Panel — compare your audit score side-by-side against up to 3 competitor URLs
  • Shareable report links — generate a public, read-only URL for any audit to share with clients or stakeholders
Improved
  • Redesigned report dashboard — findings are now grouped by priority tier (Critical, High, Medium, Low) with collapsible sections
  • LLM fix prompts updated for Claude 3.5, GPT-4o, and Gemini 1.5 — prompts now specify model context windows and output format
  • Audit speed improved by 34% — parallel crawling now runs SEO, Schema, and LLMO checks simultaneously
Fixed
  • Core Web Vitals detection no longer times out on pages behind a login wall — falls back to Lighthouse API gracefully
  • Schema validation correctly flags nested @type mismatches instead of only checking root-level properties
v1.3.2 May 2026

Patch release focused on schema detection accuracy and mobile rendering reliability.

Improved
  • Hreflang detection expanded to cover x-default and regional variants beyond top 20 locales
  • Mobile viewport simulation updated to match Chrome 124 user-agent strings
Fixed
  • Fixed false positive on "missing canonical" for paginated URLs using rel=next/prev
  • Resolved edge case where JSON-LD embedded inside a Noscript tag was counted as valid structured data
  • Report PDF export no longer truncates long fix-prompt text fields
v1.3.0 April 2026

LLMO engine expanded to cover Perplexity and Google AI Overviews citation patterns, plus a new Trust Signals audit category.

New
  • Trust Signals audit category — checks author bio schema, EAT signals, About/Contact page presence, and HTTPS coverage
  • Perplexity citation pattern analysis — 8 new LLMO checkpoints derived from Perplexity source-selection research
  • Google AI Overviews readiness score — dedicated sub-score for FAQ, HowTo, and Speakable schema coverage
  • Audit history — Pro and Teams plans now retain up to 90 days of previous audit results per domain
Improved
  • Overall scoring algorithm re-weighted to give 30% more influence to LLMO and Trust signals vs legacy SEO checks
  • Fix prompts now include a "confidence" rating so you know which suggestions are high-certainty vs exploratory
v1.2.0 March 2026

Team collaboration features and CSV export land in this release alongside a faster crawl pipeline.

New
  • Teams plan — invite up to 5 team members, manage shared domains, and annotate audit findings with internal notes
  • CSV export — download any audit as a flat spreadsheet for use in project trackers, client reports, or BI tools
  • Slack integration — receive audit completion notifications and weekly score summaries directly in any Slack channel
Improved
  • Crawl pipeline rewritten — JavaScript-heavy SPAs now render correctly before analysis (Astro, Next.js, Nuxt fully supported)
  • Improved detection of lazy-loaded images that contribute to Cumulative Layout Shift
Fixed
  • Canonical URL check now handles trailing-slash vs non-trailing-slash variants correctly
  • Subscription billing portal correctly reflects seat count changes on mid-cycle upgrades
