Backlink Checker

Check the domain signals a link audit starts from: live DNS resolution, IP footprint and Moz-derived authority and spam scores for any public domain.

✨ DOMAIN SIGNAL LOOKUP No link index is queried here — see what this page can and cannot measure below.

Enter a domain to run the lookup. Nothing is fetched until you press Check.

🌐 Name Resolution (queried live)

Hostname	Resolves	IPv4	IPv6

Multiple IPv4 addresses usually mean a load-balanced or CDN-fronted host. A missing AAAA record means the site is not reachable over IPv6.

🔎 What The Name Itself Shows

These are structural observations about the hostname. They are not ranking factors and do not predict authority on their own.

⚠️ What This Page Cannot Tell You

Backlink data lives in a crawl index. A browser page cannot enumerate who links to a domain, so no link counts, anchor texts or dofollow ratios are shown here — and any tool that displays those numbers without naming a link index is guessing.

Your own links, free and exact: Google Search Console → Links report → "Top linked pages" and "Top linking sites", plus the export button. It only covers your verified property.
Any third-party domain: a commercial index — Ahrefs, Semrush, Moz Link Explorer or Majestic (Trust Flow / Citation Flow, anchor text included).
Link quality checks you can do here today: compare the DA/PA/Spam figures above, then open the referring page in a new tab and confirm the link exists, is editorial and points at the right URL.

Next steps on this site: Domain Authority Checker for batch DA lookups, Domain Age Checker for registration dates, and Broken Link Checker to audit links you already own.

⚡ Values come from live server-side DNS resolution and Moz-derived metrics. Anything the lookup did not return is shown as "—" rather than estimated.

How to Use Backlink Checker

Follow these simple steps to get the best results.

Enter a domain

Type example.com or paste a full URL — the scheme, path, query and port are stripped down to the bare hostname automatically.

Run live lookups

The tool resolves the domain and its www host through DNS and fetches DA, PA and Spam Score from the server-side metrics lookup.

Read the verified report

Review IPv4 and IPv6 records, hostname structure and authority scores; anything the lookups did not return is shown as "—", never estimated.

Frequently Asked Questions

Everything you need to know about Backlink Checker.

Not a backlink report. It resolves the domain through DNS (IPv4 and IPv6) and fetches Domain Authority, Page Authority and Moz Spam Score from a metrics endpoint.

Yes, type a domain or paste a URL - it is reduced to the bare hostname. What you get is DNS records plus three authority metrics, never a link profile.

The DNS lookup is live. The authority and spam scores come from a third-party metrics source and are only as current as it is; anything it cannot return shows as a dash, never an estimate.

No. It reports a single Moz Spam Score for the whole domain; it cannot list individual backlinks or flag harmful ones.

Value comes from topical relevance and a page that earns its own traffic; harm comes from paid links, link farms, and spam directories with thousands of outgoing links. This tool gives only domain-level scores, so weigh those grounds against a dedicated backlink index.

They pass no direct ranking credit, but they still drive referral traffic and signal natural link diversity. A profile with only followed links looks manipulated, so a mix is healthier.

Usually nothing — Google ignores most spam links automatically. Request removal first, and only use the disavow file when a documented manual action or a large negative-SEO pattern exists, because disavowing too aggressively can cut useful links.

About the Backlink Checker Tool

Before you judge a link opportunity you need to know the domain is real, reachable and not flagged. The ToolFlic Backlink Checker resolves the domain and its www host through live DNS, reports every IPv4 and IPv6 address returned, notes the hostname structure and fetches third-party authority scores (DA, PA and Spam Score). What it deliberately does not do is invent link counts: enumerating who links to a domain needs a crawl index, so this page tells you plainly which numbers to pull from Google Search Console or a commercial index instead.

Core Advantages

Filter bad outreach targets in seconds: an unresolvable host, a missing IPv6 record, a bare domain that only answers on www, or a high spam score all show up here before you write a single email. It also gives SEO beginners an honest picture of what a free browser tool can verify and where real backlink data actually lives, so expectations stay realistic.

Architecture & Security

Two server-side lookups run in parallel: a DNS resolution query returning A and AAAA records, and a metrics query returning the Moz scale DA, PA and Spam Score for the root domain. Results are labelled with their source, unavailable values render as "—", and no metric is derived from a hash or a stored sample dataset.

Under the Hood: the Backlink Checker explained properly

No marketing filler — just the mechanics, the trade-offs and the real limits, explained clearly.

How it actually works

Despite the name it is a domain-lookup utility, not a backlink index. It strips any scheme, path, query and port down to the bare hostname, then runs two server-side lookups in parallel: a DNS resolution that returns the A and AAAA records for the domain and its www host, and a metrics query that returns third-party Domain Authority, Page Authority and Moz Spam Score for the root domain.

What that means for your results

Every figure on the report is one a lookup actually returned. The IPv4 and IPv6 addresses are the real records, while DA and PA sit on a one-to-hundred scale and Spam Score as a percentage, taken from a Moz-derived source and only as current as that source is. When a lookup answers nothing for a field the card shows a dash, never a number guessed from a hash or a saved sample.

Where it falls short — honestly

It cannot list who links to a domain, nor anchor text, dofollow or nofollow ratios, referring-domain counts or a link timeline, because those live inside a large crawl index that no browser tool maintains. Google Search Console exposes the links to your own site, and a commercial index is needed for anyone else. Treat the three scores as one provider estimate, not a Google signal.

A real end-to-end workflow

Paste a domain or a full URL and read the resolved IP footprint first, since an unresolvable host or a missing IPv6 record is a reachability problem on its own. Cross-check the Spam Score before any outreach, then confirm real link data through Domain Authority Checker for a shortlist, Domain Age Checker for registration history, and Domain to IP when you only need the addresses.
