Keyword research as an API call

Ranked keyword data from Semrush flows into the agency's own SEO platform on request, so strategists start from data instead of exports.

A compact n8n workflow: webhook, get ranked keywords from Semrush, process keywords, save to the SEO platform database, respond.
Five nodes: webhook in, Semrush, processing, platform database, response.

Challenge

Keyword research meant logging into a tool, exporting a spreadsheet, cleaning it and pasting it into the planning platform. Useful, repetitive, and impossible to trigger from inside the agency's own software.

Approach

A webhook accepts a domain or topic, pulls ranked keywords from Semrush, normalises and scores them, and posts the result into the SEO platform's database. The platform calls the workflow directly, so research becomes a button rather than a chore. The same endpoint feeds the content pipeline that plans and drafts articles.

Outcome

Strategists open the platform and the data is already there. Research went from an afternoon to the time it takes to type a domain.
