Moz Scraper: Domain Authority Checker, Spam Score & Backlink Data

Scrape Moz's free domain-analysis SEO metrics for any list of domains — no Moz account, no Moz Pro subscription, no login, and no browser. Feed it domains or URLs and get back Domain Authority (DA), Spam Score, linking root domains, ranking keywords, top linking domains, top pages, and a 60-day link-acquisition history — one clean structured record per domain, ready for JSON, CSV or Excel export.

Use Cases: SEO Competitor Analysis, Link Building Prospecting & Outreach Lists

• SEO competitor analysis — compare Domain Authority, backlinks and ranking keywords across your competitive set in one table.
• Link building prospecting — find high-DA linking domains and top pages to target for guest posts and digital PR.
• Bulk DA qualification — check 1,000+ domains at once and filter for DA >= 40 to build outreach lists.
• Spam score screening — flag low-quality domains before you buy links, rent mentions or partner with sites.
• Domain authority tracking — schedule weekly runs to watch DA, spam score and link-history trends for your own domains.

Bulk Domain Authority Check — No Moz Account, No Browser

This is the budget/Cheerio edition of the classic Moz scrapers: it reads the exact same public Moz reports but with plain HTTP + Cheerio instead of a headless browser, so it runs on tiny memory (256 MB) and a fraction of the compute of browser-based alternatives. Bulk DA qualification at 1,000s of domains for pennies.

• Cheap by design. Pure HTTP + CheerioCrawler — no browser instances, low memory, low compute.
• Bulk by design. Feed one domain or thousands; each is de-duplicated and processed in parallel.
• You never pay for empty lookups. Domains that return no usable data are skipped and never charged.
• Clean, export-ready output. Structured JSON, CSV, or Excel — ready for dashboards, BI, and prospecting sheets.
• Handles the hard part. Cloudflare challenges and Moz's per-IP free limit are handled via configurable proxy rotation — enable residential proxies for big lists (recommended default).

What it returns

For every domain you submit, this Actor pulls the public Moz domain-analysis report:

• Domain Authority (DA) — Moz's 0–100 score predicting ranking strength.
• Spam Score — the percentage risk signal.
• Linking Root Domains — count of unique referring domains.
• Ranking Keywords — total keywords the domain ranks for.
• Top Linking Domains — the strongest referring domains, each with its own DA.
• Top Pages — the domain's strongest pages, each with a Page Authority (PA).
• 60-Day Link History — discovered vs. lost linking domains over the last ~60 days.

Moz API Alternative — How to Get Moz Data Without an API Key

Moz's official API requires a Moz Pro subscription and an API key. This actor reads Moz's free public domain-analysis tool instead — no account, no key, no subscription — which makes it a practical Moz API alternative for bulk DA and backlink checks without the Moz Pro paywall.

Fast mode (bulk DA + spam-score qualification)

Turn on fastMode for pure bulk DA + spam-score qualification: it returns just the four headline metrics (Domain Authority, spam score, linking root domains, ranking keywords) with a tiny regex-based parse — no full DOM build, no tables, no link-history/chart extraction. Every row is marked fast: true. The values are still read from the live Moz report. Leave fastMode off for the complete report.

How to Use Moz Scraper

1. Open the Actor in Apify Console (or call it via the API).
2. In the Input tab, paste your domains/URLs into domains.
3. Enable Proxy configuration (RESIDENTIAL group is the recommended default) — Moz only allows ~3 free reports per IP per day, so a proxy pool makes bulk runs possible.
4. Click Start and download the dataset as JSON, CSV, HTML, or Excel.

Example call (API / MCP)

Cost Estimation: How Much Does It Cost to Scrape Moz Domain Metrics?

Pure HTTP + Cheerio — no browser rendering, no per-page GPU/CPU overhead. Each report is a single lightweight GET (~50–100 KB), so memory stays at 256 MB and compute per 1,000 domains is tiny. On top of platform usage you only pay for what the Actor consumes:

• ~3 free Moz queries per IP per day — Moz's own limit, not ours. With Apify RESIDENTIAL proxies the pool provides a fresh IP per session, so thousands of domains per run are achievable.
• Direct egress (no proxy) — free, but you'll hit Moz's IP limit after ~3 domains per run.
• Empty lookups are never charged: domains with no Moz data are skipped before billing.

To keep runs affordable, set maxItems to what you actually need and use residential proxies only for real bulk work.

Tips & Advanced Options

• Proxy is the unlock. The default input enables RESIDENTIAL — keep it for anything beyond a handful of domains.
• Low concurrency for residential (1–5) rotates IPs cleanly; raise concurrency if you run on your own proxy pool.
• Trim output by disabling includeTopPages, includeTopLinkingDomains, or includeLinkHistory to keep rows lean.
• Fast mode for bulk DA qualification. For thousands of domains where all you need is DA + spam score, flip fastMode on — leaner rows, lighter parsing, same live data.
• Cap cost with maxItems.

FAQ

Do I need a Moz account or API key? No. This Actor reads Moz's public free domain-analysis tool — no account, key, or subscription. That's what makes it a workable Moz API alternative.

Why do I need proxies? Moz allows ~3 free reports per IP per day and Cloudflare fronts the page ready to hand out 403s to datacenter IPs. The Actor already sends a fully consistent browser fingerprint (rotating Chrome User-Agent + matching Sec-CH-UA/Sec-Fetch-* headers + Referer) and rotates sessions, which clears many blocks — but for reliable bulk runs, fresh residential IPs per request are the safe path.

What is a good Domain Authority score? DA is a 0–100 relative ranking score — 40+ is generally considered strong, 60+ very strong. Use fastMode to bulk-qualify prospects against your own threshold (e.g. DA >= 40).

How to check Domain Authority for free at scale? Run this actor with fastMode: true and a residential proxy pool — it returns live DA, spam score, linking root domains and ranking keywords for thousands of domains at pennies per thousand.

Moz vs Ahrefs Domain Rating — which should I use? Both are competitive link-based metrics; DA is widely quoted in outreach and guest-posting circles, while Ahrefs DR is common in SEO tooling circles. Pair the Ahrefs Scraper with this actor to cover both metrics.

What happens for a domain Moz has no data on? The domain is skipped and never billed.

For AI Agents & LLM Apps

One dataset record per domain: Moz Domain Authority, Spam Score, linking root domains, ranking keywords, top linking domains (with DA), top pages (with PA) and 60-day link history — wired for the Apify MCP server and the Apify API.

Minimal working input (fast DA check):

{
  "domains": ["apify.com", "stripe.com"],
  "fastMode": true
}

Variant — full report:

{
  "domains": ["apify.com"],
  "fastMode": false,
  "includeTopLinkingDomains": true,
  "includeTopPages": true,
  "includeLinkHistory": true
}

Output field list: input, domain, domainAuthority, linkingRootDomains, rankingKeywords, spamScore, topLinkingDomains[{domain,da}], topPages[{url,pa}], linkHistory[{date,discovered,lost}], checkedAt, source, fast.

Behaviors an agent should know:

• domains is the only required field; each unique host is looked up once (de-duplicated).
• In fastMode, topLinkingDomains, topPages and linkHistory are always omitted and rows are flagged fast: true.
• Domains with no Moz data are skipped and not billed — do not treat missing rows as errors.
• Without a proxy pool you'll typically get ~3 free reports per IP per day before Moz limits; enable RESIDENTIAL proxies for anything beyond a few domains.
• maxItems caps billable results — set it to your actual list size.
• Metrics are Moz's estimates, not guarantees.

Billing model: pay-per-event (compute + proxy traffic actually consumed); pricing from $5 per 1,000 results.
