Semrush is a popular SEO tool suite that specializes in keyword research, competitor analysis, and Google Ad campaign optimization.
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.
Compares backlink profiles for multiple specified targets (domains, subdomains, or URLs) to analyze and compare link-building efforts.
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.
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.
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.
Analyzes keyword rankings by comparing up to five domains to find common, unique, or gap keywords, using specified organic/paid types and comparison logic in the `domains` string.
Call this to find related keywords (including synonyms and variations) for a target phrase in a specific regional database; `display_date` (if used for historical data) must be 'YYYYMM15' for a past month. Response is CSV-like delimited text (not JSON); parse by splitting on newlines and delimiters to extract structured rows.
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.
Use this action to get a CSV report of anchor texts for backlinks pointing to a specified, publicly accessible domain, root domain, or URL.
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.
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.
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.
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.
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.
Use to get a domain's organic search competitors from Semrush as a semicolon-separated string; `display_date` requires 'YYYYMM15' format if used.
Retrieves a list of a domain's competitors in paid search results from a specified regional database.
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.
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.
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.

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.
