SEO Helper (on-page audit + SERP preview)

On-page SEO audits and Google SERP snippet previews as a simple API — a port of the SEO Minion browser extension. No API keys needed. Keyless, plain HTTP fetching (no browser), fast and cheap.

A common SEO question before you make changes: "will my clicks and traffic change?" You find out by running a quick SEO audit — check the snippet and content quality of key pages before and after you change anything, or before you start an SEO campaign (e.g. before moving a new niche site from keyword research to actual edits).

How this compares

Two modes in one actor, an on-page audit (page-audit, $0.001 per page) and a Google SERP snippet preview (serp-preview, $0.001 per page), both over plain HTTP with no browser and no API key. At $1.00 per 1,000 pages it is far below the audit tools below: smart-digital/complete-seo-audit-tool ($40.00 per 1,000 pages analysed), logiover/website-seo-audit-crawler ($10.00), ittechinnovators/advanced-seo-audit-tool---ai-powered-insights ($10.00) and autofacts/metadata-scraper ($5.00). Those tools may return a broader report; check their listings for what each row contains. Platform usage is paid by you on top of the event price.

What it does

Mode onpage — full on-page SEO audit (default)

One audit per URL. Each row extracts:

• Title & meta description — value, character length, and a Google over-limit flag
• Canonical tag — value plus automatic canonical-mismatch detection
• Meta robots / meta refresh — indexability signals (noindex flagged)
• Headings H1–H6 — outline text plus H1 count/duplicate checks
• Word count
• Images — total and missing-alt count with URLs
• Open Graph & Twitter card tags
• Links — full list and counts (internal / external / follow / nofollow / sponsored / UGC)
• Hreflang alternates, JSON-LD structured data, microdata itemtypes
• Flat issue flags for quick scanning: missing-title, title-too-long, missing-meta-description, no-h1, multiple-h1, canonical-mismatch, noindex, all-images-missing-alt
• Redirect chain — every HTTP hop with status codes, plus per-row HTTP status and fetch error text

Mode serp_preview — Google snippet preview

One preview per URL: pulls the live title and meta description, applies Google-style truncation (60/155 chars, word-boundary ellipsis), and flags whether Google would truncate it. Optionally override the title/description for specific URLs (useful for testing a rewrite before you publish it).

Input options

{
  "mode": "onpage",
  "pageUrls": ["https://example.com/product/1", "https://example.com/blog/post"],
  "maxUrls": 500,
  "includeLinks": true,
  "fetchTimeoutSec": 30,
  "proxyUrl": ""
}

Field	Type	Default	Description
mode	onpage | serp_preview	onpage	Audit mode or SERP preview mode
pageUrls	list of strings	["https://example.com"]	URLs to audit or preview. A single URL string is also accepted.
maxUrls	integer ≥ 1	(empty = no limit)	Optional cap on how many URLs are processed per run
serpOverrides	list of objects	(empty)	serp_preview only: { "url": "...", "title": "...", "description": "..." } overrides applied before truncation
useLivePage	boolean	true	serp_preview only: pull title/description from the live page before applying overrides (false = use overrides only)
includeLinks	boolean	true	onpage only: include the full link + image lists (disable for leaner rows)
fetchTimeoutSec	integer 5–120	30	Per-page fetch timeout in seconds
proxyUrl	string	(empty)	Optional HTTP(S) proxy for the fetches

Sample output (one row)

{
  "recordType": "page-audit",
  "url": "https://example.com/page",
  "finalUrl": "https://example.com/page",
  "httpStatus": 200,
  "redirectChain": [],
  "issues": ["missing-meta-description", "no-h1"],
  "audit": {
    "title": "Example Page Title",
    "titleLength": 18,
    "titleOverLimit": false,
    "description": "",
    "canonical": "https://example.com/page",
    "canonicalMatchesUrl": true,
    "robots": "index, follow",
    "headings": [{"tag": "H1", "text": "Welcome"}],
    "wordCount": 312,
    "imagesTotal": 4,
    "imagesMissingAlt": 1,
    "openGraph": {"og:title": "Example Page Title"},
    "linkCounts": {"total": 12, "internal": 8, "external": 4},
    "hreflang": [],
    "structuredData": []
  }
}

Pages that could not be fetched (HTTP 404/5xx, timeouts, blocks) are delivered as rows with a populated error field, a null audit, and clear status messaging — so you always see exactly which URLs failed.

Usage notes

• URLs are processed sequentially; a typical run processes 150–300 URLs/minute. Use maxUrls on very large URL lists to stay within the platform timeout.
• Works with most websites; sites with aggressive anti-bot protection may need the proxyUrl option.
• The SERP preview is an approximation of Google's presentation rules (60/155 chars with word-boundary truncation); Google may render snippets differently per query.
