Core Workflows

1. Domain Organic Keywords Analysis

Retrieve all organic search keywords for a domain, including positions, traffic estimates, CPC, and keyword difficulty.

Tool: SEMRUSH_DOMAIN_ORGANIC_SEARCH_KEYWORDS

Key parameters:

• domain (required) -- e.g., example.com
• database (required) -- regional database code (e.g., us, uk, de)
• display_limit (default 10000) and display_offset (default 0) -- pagination
• display_sort -- sort by position, traffic, volume, etc. (e.g., tr_desc for traffic descending)
• display_date -- historical data in YYYYMM15 format (monthly) or YYYYMMDD (daily)
• export_columns -- specify columns like Ph (phrase), Po (position), Nq (volume), Tr (traffic), Kd (difficulty)
• display_filter -- filter by specific columns

Example prompt: "Get the top 100 organic keywords for example.com in the US database, sorted by traffic"

2. Keyword Overview and Batch Analysis

Get detailed metrics for individual keywords or analyze up to 100 keywords at once.

Tools: SEMRUSH_KEYWORD_OVERVIEW_ONE_DATABASE, SEMRUSH_BATCH_KEYWORD_OVERVIEW

For single keyword:

• phrase (required) -- keyword to investigate

• phrase (required) -- semicolon-separated keywords (max 255 chars total)
• database (required) -- regional database
• export_columns -- Ph (phrase), Nq (volume), Cp (CPC), Co (competition), Kd (difficulty), In (intent)

Example prompt: "Get keyword metrics for 'seo services;content marketing;link building' in the US database"

3. Domain Organic Pages Report

4. Backlink Profile Overview

5. Keyword Difficulty Assessment

Known Pitfalls

• Pagination is essential: SEMRUSH_DOMAIN_ORGANIC_SEARCH_KEYWORDS and SEMRUSH_DOMAIN_ORGANIC_PAGES can return very large datasets. Always use display_limit and display_offset instead of assuming a single page is complete.
• CSV-style responses: Many SEMrush tools return data as CSV-style text in a single field (e.g., data/keyword_data). You must parse rows and columns before analysis or joining reports.
• "ERROR 50 :: NOTHING FOUND": This literal string means the domain or keyword has no data in that database. Treat it as a valid zero-result response, not a transport error.
• Batch keyword limits: SEMRUSH_BATCH_KEYWORD_OVERVIEW may return HTTP 400 for problematic or oversized batches (max 255 chars total for the phrase field). Shrink batches or fall back to SEMRUSH_KEYWORD_OVERVIEW_ONE_DATABASE for individual lookups.
• Date format: Historical dates must use YYYYMM15 format for monthly data (e.g., 20231015). Using an incorrect format will return unexpected results.
• Regional database matters: Always use the correct regional database for your target audience. Results for us vs uk can differ dramatically in volume, CPC, and rankings.
• Column codes: Export columns use short codes (Ph, Nq, Kd, etc.). Avoid over-narrowing export_columns so key metrics like traffic, CPC, position, and difficulty are retained.
