Question 1

What does the Referring Domains Explorer do?

Accepted Answer

Paste backlink data (source URL, target URL, optional anchor and DA) and the tool extracts unique referring domains, ranks them by link count, estimates domain authority, computes TLD distribution, and lists anchors per domain. No network calls — all parsing happens in your browser.

Question 2

How is domain authority estimated when I don't provide DA values?

Accepted Answer

We use a transparent heuristic: .gov and .edu domains get 80, common TLDs (.com/.org/.net/.io/.co) get 50, suspicious TLDs (.xyz/.top/.online) get 15, and other TLDs default to 30. When you provide DA values in your CSV, we average them per domain and use that instead.

Question 3

What input format does it accept?

Accepted Answer

CSV with header (source_url, target_url, anchor, da) or headerless rows in that same column order. Tab-separated values also work.

Question 4

What extra features does this tool have compared to others?

Accepted Answer

(1) Unique domain extraction. (2) Link count per domain. (3) Top domains ranking. (4) Algorithmic DA estimate. (5) TLD distribution. (6) Anchor text per domain. (7) CSV export. (8) Plain-text report copy. (9) History (localStorage, last 20). (10) Shareable URL — encode input in fragment.

Question 5

Is my data sent anywhere?

Accepted Answer

No. All extraction runs locally. History is stored in localStorage on this device only.
