Semrush actions 37

Every Semrush action below is a callable tool any Definable persona can invoke.

Check Semrush account units balance

Tool to fetch the remaining Semrush Standard API units for the authenticated account. Use this before launching large batches of Semrush report requests to preflight and fail fast if units are exhausted or below a required threshold.

Get ad copies

Retrieves unique ad copies Semrush has observed for a specified domain from a regional database, detailing ads seen in Google's paid search results. Results are a sampled subset, not a complete picture of the domain's advertising. Response is returned as a CSV-like string; parse columns (e.g., Tt, Ds) using the pipe or semicolon delimiter.

Get anchor texts

Use this action to get a CSV report of anchor texts for backlinks pointing to a specified, publicly accessible domain, root domain, or URL.

Get authority score profile

Retrieves the Authority Score (AS) profile for a specified target, showing the count of referring domains that link to the target for each AS value from 0 to 100.

Get backlinks

Fetches backlinks for a specified domain or URL as a semicolon-delimited CSV string (parse with `sep=';'`); allows customization of columns, sorting, and filtering. Consumes Semrush API credits per request. Ensure `display_limit` surpasses `display_offset` when an offset is used, and note the `urlanchor` filter may have limitations for targets with extensive backlinks.

Backlinks overview

Provides a semicolon-delimited (sep=';') CSV summary of backlinks, including Authority Score and link type breakdowns, for a specified and publicly accessible domain, root domain, or URL. A result of 'ERROR 50 :: NOTHING FOUND' means the target has no data in the database and is a valid zero-result response.

Batch comparison

Compares backlink profiles for multiple specified targets (domains, subdomains, or URLs) to analyze and compare link-building efforts.

Batch keyword overview

Fetches a keyword overview report from a Semrush regional database for up to 100 keywords, providing metrics like search volume, CPC, and keyword difficulty. Response is CSV-like text (not JSON); parse accordingly. Returns literal string 'ERROR 50 :: NOTHING FOUND' for keywords with no data in the selected database — treat as zero results and fall back to SEMRUSH_KEYWORD_OVERVIEW_ONE_DATABASE or SEMRUSH_KEYWORD_OVERVIEW_ALL_DATABASES for those terms.

Broad match keyword

Fetches broad match keywords for a given phrase. Response is CSV-like text (not JSON); parse by splitting on line breaks and delimiters. `display_sort` and `display_filter` parameters are defined but currently not utilized by the API call.

Get categories

Retrieves categories and their 0-1 confidence ratings for a specified domain, subdomain, or URL, with results sorted by rating. Response is returned as semicolon-separated text in a single 'data' field requiring parsing before use. Some niche or atypical targets may return no category data.

Get categories profile

Retrieves a profile of content categories from referring domains for a specified target, analyzing its first 10,000 referring domains and sorting results by domain count.

Get competitor data

Retrieves a CSV-formatted report of competitors for a specified target (root domain, domain, or URL) based on shared backlinks or referring domains. Output is a CSV string; use display_limit and display_offset to paginate without silent truncation.

Get competitors in organic search

Use to get a domain's organic search competitors from Semrush as a semicolon-separated string; `display_date` requires 'YYYYMM15' format if used.

Get competitors in paid search

Retrieves a list of a domain's competitors in paid search results from a specified regional database.

Get domain ad history

Retrieves a domain's 12-month advertising history from Semrush (keywords bid on, ad positions, ad copy) for PPC strategy and competitor analysis; most effective when the domain has ad history in the selected database.

Get domain organic pages

Fetches a report on a domain's unique organic pages ranking in Google's top 100 search results, with options for specifying database, date, columns, sorting, and filtering. Response is semicolon-separated CSV text in a single `data` field requiring explicit parsing. The literal response `ERROR 50 :: NOTHING FOUND` means zero results for that domain/database combination, not a system error. Traffic metrics (e.g., `Tr`) are modeled estimates incompatible with first-party analytics data.

Get domain organic search keywords

Retrieves organic search keywords for a domain from a specified Semrush regional database; `display_positions` must be set if `display_daily=1` for daily updates. Response is semicolon-delimited CSV text (parse with sep=';', cast numeric columns before aggregations). A response of 'ERROR 50 :: NOTHING FOUND' indicates no data for the domain in the selected database — treat as a valid zero-result.

Get domain organic subdomains

Retrieves a report on subdomains of a given domain that rank in Google's top 100 organic search results for a specified regional database.

Get domain paid search keywords

Fetches keywords driving paid search traffic to a specified, existing domain using a supported Semrush regional database.

Retrieves monthly historical backlink and referring domain data for a specified root domain, returned as a time series string with newest records first.

Get indexed pages

Retrieves a list of indexed pages from Semrush for a specified `target` (root domain, domain, or URL) and `target_type`, ensuring `target` is publicly accessible, Semrush-analyzable, and correctly matches `target_type`. Returns CSV-like text output requiring parsing before structured analysis.

Get keyword overview for one database

Fetches a keyword summary for a specified phrase from a chosen regional database. Returns CSV-like text (not JSON) with column headers matching `export_columns` codes (e.g., 'Ph', 'Nq', 'Kd'); parse headers and rows into structured data before use. A plain-text 'ERROR 50 :: NOTHING FOUND' response indicates zero results, not a transport error.

Get organic results
