Seoprog v2.3

Audit one page. Paste its HTML (or enter a URL and hit Try fetch) to get an SEO score and an AI-readiness score, plus a checklist. Then "Copy AI fix prompt" to get the repairs written for you.

On-page audit

Paste a page's HTML, or fetch a live URL once deployed (the proxy bypasses the browser CORS wall). Running locally, fetch may be blocked — paste source instead.

Page HTML

Optional: try fetching a URL

Audit your whole site at once. Enter your URL - it scores every page, flags duplicate titles and descriptions, and the "AI site fix plan" button writes a prioritized to-do list.

Site crawl

Audits every page from your sitemap.xml (falls back to homepage links if there's no sitemap) and scores each for SEO and AI readiness. Needs the deployed proxy - running locally most sites will be unreachable.

Site URL

Max pages

See your page before you publish. Type a title and description to preview the Google result and social card, keep them inside the green counts, then copy the ready-made tags into your page head.

Compose

Type once — see Google, see the social card, copy the meta block.

Can AI assistants find and recommend you? Check whether your robots.txt blocks AI crawlers, generate an llms.txt, and spot-check your visibility in AI answers. Add your API key here to turn on "Run with AI" everywhere.

AI crawler access

Checks your robots.txt for the crawlers that feed ChatGPT, Claude, Perplexity, Gemini and Copilot. A site that blocks these is invisible to AI answers - and most owners never checked. Also looks for an llms.txt.

Site URL or domain

Run AI in-app (bring your own key)

Paste an Anthropic API key and the "Run with AI" buttons execute prompts here instead of via copy-paste. The key is stored only in this browser and sent only with your own requests - never to anyone else.

AI visibility spot check

Asks Claude buyer-intent questions about your niche with live web search, then checks whether your brand or domain appears in the answers. The GEO question, answered for the cost of a few API calls.

Your fix ledger. Watch a page after you fix it - Seoprog keeps a record of its scores and tells you if a fix ever silently breaks. Re-check any time; Pro re-checks on a schedule and emails you.

Where Seoprog is headed. A quick read on what it does today and what is planned next.

Where this goes next

Phase 1 is this single file: everything runs in the browser, data lives in localStorage, exportable to JSON. When it earns the upgrade, these move server-side.

Scheduled rank checks — a cron job snapshots positions automatically instead of manual logging.
GSC OAuth sync — pull clicks/impressions/position straight from Search Console on a schedule, no CSV step.
Managed AI plan — BYO-key execution is live. The paid flip: set ANTHROPIC_API_KEY as a Pages secret, add auth + per-user metering in front of /api/ai, clients stop sending keys. Same endpoint, same shape.
Scheduled visibility checks — the spot check is live; the subscription version runs it weekly via cron and alerts when your brand appears or disappears from AI answers.
Storage — Supabase table swaps in behind the same data shape used here, so the migration is a thin adapter, not a rewrite.

Architecture note: the tracker reads/writes through one store object. Point that at an API later and the UI doesn't change — same pattern as your other builds.
