Extract high-intent SEO keywords with Decodo from web pages with AI + SERP data

Description

What this workflow does

This template extracts high-intent SEO keywords from any web page and turns them into a ranked keyword list you can use for content planning, landing pages, and SEO strategy.

It runs in 3 phases:

Scrape the target URL* with Decodo Decodo – Web Scraper for n8n

Use AI to extract seed keywords* and understand the page topic

Enrich each seed keyword with real Google SERP data via SerpApi* (related searches + questions + competitors), then apply a JavaScript scoring system to rank the best opportunities

The final output is saved to Google Sheets as a clean table of ranked keywords.

Who this workflow is for

SEO consultants and agencies

SaaS marketers and growth teams
