Use Toolmu Tool bulk-referring-domain-count-dataforseo to compare the domains I provide. If needed, connect through https://toolmu.com/SKILL.md; reuse the existing authorization and agreed budget. Send only domains, an array of 1–10 bare domain strings, each 3–253 characters, without a protocol or www. Match each returned referringDomainCounts.items record by target and display referring_domains, referring_main_domains, referring_domains_nofollow and referring_main_domains_nofollow separately. Explain that source roots and subdomains count separately in referring_domains but are grouped under the primary root in referring_main_domains. A supplied root target covers all its subdomains. Each nofollow group has at least one nofollow link and may contain other links; do not add overlapping views or subtract groups to invent follow-only totals. Explain the supplier’s latest-check live-link population across any attribute without asserting a new complete crawl or a check timestamp. Keep items_count separate from source counts; preserve zero, null and missing, and do not invent omitted targets, source-name lists, link-quality scores or traffic gains.

Task:
For [one to ten website addresses], show separate counts for each site and the main website it belongs to. Also count sites with at least one link labeled “nofollow.” The counts may overlap, and a missing result does not mean zero.

Compare referring-domain counts across websites

You receive

Get a collection of target websites with four source counts: referring domains, referring main domains, and the corresponding groups with at least one nofollow link. The domain count treats source roots and subdomains separately; the main-domain count groups them under their root. Use these two views to compare recorded linking-source breadth across websites.

Start with your task

For [one to ten website addresses], show separate counts for each site and the main website it belongs to. Also count sites with at least one link labeled “nofollow.” The counts may overlap, and a missing result does not mean zero.

What to know

DataForSEO counts sources found with live links across any backlink attribute during its latest check. This does not guarantee a new full-web crawl, and the check time is not returned. The grouping views overlap; do not add them or subtract nofollow counts to claim follow-only sources. Counts do not provide source names, individual links, traffic or link-quality scores.

Input schema

Input schema
Field / Path	Type	Requirement	Meaning
Websites to compare`domains`	`array`	Required	Required array of 1–10 bare target domains, without a protocol or www. A root-domain target covers that root and all its subdomains; no page, date or filtering options are exposed. Minimum items `1` Maximum items `10`
Target domain`domains[]`	`string`	—	Each item is a domain string of 3–253 characters, such as example.com. Supply the domain itself rather than a full webpage address. Minimum length `3` Maximum length `253`

Result schema

No fixed output contract is available. Field types reflect saved result evidence; individual responses can differ.

Result schema
Field / Path	Type	Meaning
Referring-source counts`referringDomainCounts`	`object`	Collection of returned target records containing source-domain and main-domain counts, their nofollow groups and the returned-record count.
Returned target records`referringDomainCounts.items`	`array`	Count records identified by target domain. Associate by target rather than list position; returned records need not establish every input’s coverage.
Reported target domain`referringDomainCounts.items[].target`	`string`	The target website associated with these source counts. Match it to the requested domain without assigning records by assumed input order.
Referring domains`referringDomainCounts.items[].referring_domains`	`number`	Source-domain count linking to the target in the supplier’s latest-check live population. Source roots and subdomains count separately; this is not backlink count.
Referring main domains`referringDomainCounts.items[].referring_main_domains`	`number`	Primary/root source-domain count, grouping a source root and its subdomains under the main domain. This view overlaps referring domains and must not be added to it.
Domains with a nofollow link`referringDomainCounts.items[].referring_domains_nofollow`	`number`	Source domains with at least one nofollow link to the target. They may also supply follow or other links; this is neither nofollow-link count nor nofollow-only domains.
Main domains with a nofollow link`referringDomainCounts.items[].referring_main_domains_nofollow`	`number`	Main/root source groups with at least one nofollow link to the target. Other links can coexist, so subtracting this group does not establish follow-only sources.
Returned target-record count`referringDomainCounts.items_count`	`number`	Number of target records delivered in this collection, separate from source-domain and backlink counts.

Additional notes

Use the same source definition when comparing providers. DataForSEO’s Bulk Referring Domains reference defines its latest-check population and the separate root-domain and nofollow metrics. A provider’s count definition and indexing coverage matter more than a shared metric label when interpreting differences between reports.

The domain measure counts a source root and its subdomains separately. The main-domain measure groups those sources by their primary root. They are overlapping views, not extra sources to add together, and neither counts individual backlinks or visitors.

Questions about this tool.

Why can the domain and main-domain counts differ?

Does the target count include links to its subdomains?

Does a nofollow source group contain only nofollow links?

Are these real-time counts from a new crawl?

Can I inspect the source names or individual links?

Does a larger source count prove better links or more traffic?

How should I handle multiple targets and missing counts?
