Use backlink-history-dataforseo for one website. Accept a website address, full URL or domain. Parse a provided URL with a URL parser, take its hostname, remove the scheme, path, query and fragment, and remove only a leading www. prefix; preserve other subdomains. If the address is missing or ambiguous, ask in plain language for the website link; do not ask the user to rewrite it as a bare domain. Pass one domain string of 3–253 characters. Reuse the existing Toolmu connection and authorization, or follow https://toolmu.com/SKILL.md, and stay within the agreed budget. Compare the actual returned historical observations. Separate incoming backlinks and source-page/domain/main-domain counts from outgoing links. Explain new and lost values as comparisons with the previous period, without forcing them to reconcile total changes. Preserve original counts, null maps, false flags and zeros; leave missing periods unknown. Treat date as the supplier’s data-storage time, separate from link-event dates and the source’s monthly reporting basis. Explain uncertainty in comparisons before May 2021 without replacing reported values. Keep historical domain rank and average target-page spam in their proper scopes. Report returned coverage without promising history through today, individual link URLs or ongoing monitoring.

Task:
Show how the number of links to [website link] and the number of websites linking to it changed in the available records. Point out recorded increases, decreases, and missing months. A month with no record does not mean there were no links, and the data may not reach today.

Review a website’s backlink history

Give your Agent a domain to compare available historical incoming-link and referring-domain counts, with reported new and lost links between periods.

You receive

Get available monthly records for one domain, including incoming backlink and referring-source counts, reported new and lost comparisons with the previous period, and domain metrics for each record. Compare the covered months while keeping links, source pages and source domains as separate counting units.

Start with your task

Show how the number of links to [website link] and the number of websites linking to it changed in the available records. Point out recorded increases, decreases, and missing months. A month with no record does not mean there were no links, and the data may not reach today.

What to know

Coverage can have gaps and may not reach the present; date selection is not available. Stored dates are not exact link-event times. New and lost counts need not reconcile changes in totals, and comparison data before May 2021 needs cautious interpretation.

Inputs & outputs

Inspect the current inputs, availability, and maximum charge before starting.

Result schema

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

Result schema
Field / Path	Type	Meaning
Domain backlink history`backlinkHistory`	`object`	Available historical observations for the requested domain, returned date bounds when available, and the delivered observation count.
Queried domain`backlinkHistory.target`	`string`	Domain reported for this historical lookup.
Historical observations`backlinkHistory.items`	`array`	Historical backlink counts and related metrics. The supplier describes monthly aggregation based on backlinks present on the first day of each month; storage timestamps are separate from that reporting basis. Coverage can have gaps, and early period comparisons need cautious interpretation.
Returned observation count`backlinkHistory.items_count`	`number`	Number of historical records delivered in this result, not a guarantee of one record for every month.
Returned starting date`backlinkHistory.date_from`	`null`	Starting date bound reported by the supplier when available. Null leaves that bound unknown; this is not an input date selector.
Returned ending date`backlinkHistory.date_to`	`null`	Ending date bound reported by the supplier when available. Null does not establish coverage through today.
Data storage time`backlinkHistory.items[].date`	`string`	UTC timestamp when the supplier stored the target data. It is not the exact time a backlink appeared or disappeared, a month-end balance date, or the lookup’s completion time.
Historical incoming backlinks`backlinkHistory.items[].backlinks`	`number`	Incoming backlink count reported in this historical observation. Multiple links can come from the same page or domain; this is not an individual URL list.
Historical source-page count`backlinkHistory.items[].referring_pages`	`number`	Number of source pages reported as linking to the target in this observation, separate from the number of links.
Historical source-domain count`backlinkHistory.items[].referring_domains`	`number`	Reported source domains for the observation, with subdomains counted separately.
Historical main-domain count`backlinkHistory.items[].referring_main_domains`	`number`	Reported source main domains, grouping subdomains under their main domain. This uses a different unit from the domain count.
Source pages with nofollow links`backlinkHistory.items[].referring_pages_nofollow`	`number`	Historical source pages with at least one nofollow link to the target. This counts pages, not individual nofollow links.
Source domains with nofollow links`backlinkHistory.items[].referring_domains_nofollow`	`number`	Historical source domains with at least one nofollow link to the target. They may also provide other link types.
Main domains with nofollow links`backlinkHistory.items[].referring_main_domains_nofollow`	`number`	Historical source main domains with at least one nofollow link to the target.
New backlinks versus the previous period`backlinkHistory.items[].new_backlinks`	`number`	Supplier-reported new incoming backlinks in comparison with the previous period. This is a period comparison rather than a list of dated acquisition events.
Lost backlinks versus the previous period`backlinkHistory.items[].lost_backlinks`	`number`	Supplier-reported lost incoming backlinks in comparison with the previous period. Loss does not mean the links became harmful.
New source domains versus the previous period`backlinkHistory.items[].new_referring_domains`	`number`	Supplier-reported new referring domains compared with the previous period, separate from new backlink counts.
Lost source domains versus the previous period`backlinkHistory.items[].lost_referring_domains`	`number`	Supplier-reported lost referring domains compared with the previous period, separate from lost backlink counts.
Historical domain backlink rank`backlinkHistory.items[].rank`	`number`	Supplier score for the target domain at this observation, with a documented default scale of 0–1000. It is not a Google search position, page score or traffic metric.
Historically crawled pages`backlinkHistory.items[].crawled_pages`	`number`	Supplier count of crawled target pages in this observation. It does not establish a complete sitemap or present-day coverage.
Recorded domain details`backlinkHistory.items[].info`	`object`	Available historical server, CMS, platform, IP and country information, plus the target spam score and target-as-IP flag. These describe the recorded target; null values remain unknown and do not verify current network or technology.
Average target-page spam score`backlinkHistory.items[].info.target_spam_score`	`number`	Supplier’s average modeled spam score across the domain’s pages. It is separate from incoming-backlink spam and does not prove a penalty, safety or a harmful-link proportion.
Historical outgoing internal links`backlinkHistory.items[].internal_links_count`	`number`	Sum of links on target pages that point within the site, as reported for the observation. These are outgoing page links rather than incoming backlinks.
Historical outgoing external links`backlinkHistory.items[].external_links_count`	`number`	Sum of links on target pages that point to other websites, as reported for the observation. These are separate from incoming backlinks.
Incoming links by domain suffix`backlinkHistory.items[].referring_links_tld`	`object`	Historical incoming-link counts by original source-domain suffix labels. Keep the reported keys; this does not promise a complete distribution.
Incoming links by type`backlinkHistory.items[].referring_links_types`	`object`	Historical counts by supplier link-type labels, such as anchor, image, redirect or canonical when returned. They describe link forms, not their ranking effect.
Incoming links by reported country`backlinkHistory.items[].referring_links_countries`	`null \| object`	Historical incoming-link counts by reported source-country labels. A null map, empty label or WW entry retains its original value; this does not locate visitors.
Incoming links by attribute`backlinkHistory.items[].referring_links_attributes`	`object`	Historical counts by attributes such as nofollow or ugc. Several attributes can apply to one link, so the categories may overlap; a null map remains unknown.
Incoming links by source platform`backlinkHistory.items[].referring_links_platform_types`	`object`	Historical counts by supplier-assigned source-platform labels. Unknown labels stay as reported and do not certify the source site’s technology.
Incoming links by source-page area`backlinkHistory.items[].referring_links_semantic_locations`	`object`	Historical counts by reported areas such as main content, navigation or footer. Empty labels remain unknown; these are link counts rather than user clicks.

Questions about this tool.

How much history can I retrieve, and can I choose a date range?

Does each date tell me when links appeared or disappeared?

Can I calculate the change in total backlinks by subtracting lost from new?

How should I use comparison counts from early periods?

Are referring domains and outgoing links the same as backlinks?

What do historical domain rank and target spam score mean?

Will I get individual backlink URLs or ongoing change alerts?
