Use Toolmu Tool bulk-new-lost-referring-domains-dataforseo to compare changes in websites that link to the websites I share. Reuse the existing connection and authorization; if setup is needed, follow https://toolmu.com/SKILL.md and stay within the agreed budget. Ask for 1–10 website links and accept a link to a specific page; never ask the user to extract or edit a domain. For each valid URL, use its host as the lookup target after removing the URL scheme, port, path, query, fragment, and one leading www.; preserve any other subdomain. If a link is unclear, ask for the full website link in plain language. Match every returned record by target. Show new_referring_domains, lost_referring_domains, new_referring_main_domains and lost_referring_main_domains separately; items_count counts returned target records. Explain that one view counts linking website addresses separately while the other groups addresses under the same main website; never add these overlapping views. State the documented default threshold as DataForSEO’s current date minus one calendar month; the result omits exact dates and timezone. Interpret new/lost as supplier-index appearance/nonfinding, not verified creation or permanent removal. Preserve null, missing and zero; identify absent targets without inventing records, a reconciled current total, link URLs, quality scores or current coverage.

Task:
Compare which websites are newly found or no longer found for [one to ten website links]. Count each website address separately, and also group addresses that belong to the same main website. These counts may overlap, so do not add them. No result does not mean zero.

Compare new and lost referring domains

Give your Agent 1–10 domains to compare DataForSEO’s new and lost referring-source counts. See separate counts for source domains and for sources grouped by their main domain.

You receive

Receive a record for each returned target with four counts: new and lost referring domains, plus new and lost referring main domains. The first pair counts source roots and subdomains separately; the second groups sources under their main domain. Compare the two views separately to understand reported changes in referring sources across websites.

Start with your task

Compare which websites are newly found or no longer found for [one to ten website links]. Count each website address separately, and also group addresses that belong to the same main website. These counts may overlap, so do not add them. No result does not mean zero.

What to know

DataForSEO uses a default threshold of its current date minus one calendar month. Exact dates and timezone are not returned. These are index observations, not proof of link creation or permanent removal. The two grouping views overlap and cannot be added; new minus lost does not establish the current source total. Source names, link URLs and ongoing monitoring are not delivered.

Input schema

Input schema
Field / Path	Type	Requirement	Meaning
Domains to compare`domains`	`array`	Required	Required array of 1–10 bare target domains. The endpoint covers each target root and its subdomains; this input has no date or filtering options. Minimum items `1` Maximum items `10`
Target domain`domains[]`	`string`	—	Each array item is a 3–253-character domain string without a protocol or www, for example openai.com. Supply a domain rather than a page URL. 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 change result`newLostReferringDomains`	`object`	Collection containing returned target records with separate new/lost source-domain and source-main-domain counts, plus the returned-record count.
Target records`newLostReferringDomains.items`	`array`	Returned records for the requested comparison. Associate each record with its target; list position does not establish input order or complete input coverage.
Reported target`newLostReferringDomains.items[].target`	`string`	The target attached to this count record. Use it to associate the four counts with the requested website.
New referring domains`newLostReferringDomains.items[].new_referring_domains`	`number`	Source-domain count that appeared in the supplier’s index after the default threshold. Source roots and subdomains are counted separately; this is not a backlink count.
Lost referring domains`newLostReferringDomains.items[].lost_referring_domains`	`number`	Source-domain count present before the default threshold but not found afterward. Roots and subdomains are counted separately; nonfinding does not prove permanent removal.
New referring main domains`newLostReferringDomains.items[].new_referring_main_domains`	`number`	New-source count grouped by main/root domain, without separate counts for its subdomains. This view overlaps the new referring-domain count and must not be added to it.
Lost referring main domains`newLostReferringDomains.items[].lost_referring_main_domains`	`number`	Lost-source count grouped by main/root domain, without separate counts for its subdomains. This view overlaps the lost referring-domain count and must not be added to it.
Returned target-record count`newLostReferringDomains.items_count`	`number`	Number of target records returned in this collection. It is separate from the four referring-source counts.

The documented default starts at DataForSEO’s current date minus one calendar month. It is not a fixed 30-day window or the previous complete calendar month. This Tool has no date selector, and the result does not supply the exact threshold dates or timezone.

Questions about this tool.

Which period do the counts cover?

How do referring-domain and main-domain counts differ?

Are subdomains of my target included?

Does a lost referring domain mean its links were deleted?

Can I use new minus lost as my current total or an SEO score?

Will I get source names, link URLs or alerts?

How should I compare several domains and missing values?
