This Langflow flow implements an end-to-end SEO keyword research and planning pipeline.

It starts with seed keywords and optional business context (target audience, product priorities, geographic focus, and domain constraints). A SerpAPI stage queries search results and related keyword signals, capturing metrics such as estimated search volume, difficulty/competition proxies, and SERP characteristics that suggest intent.

A clustering stage groups keyword candidates into themes using semantic similarity and intent cues. This helps prevent keyword cannibalization by identifying which terms belong on the same page and which should be separated into distinct content pieces.

A prioritization stage scores clusters based on opportunity (volume, difficulty, topical relevance, conversion potential) and produces a ranked roadmap. The workflow can generate quick-win recommendations by identifying clusters where volume is meaningful but competition is relatively low for the site’s context.

Finally, the flow generates a content strategy output: cluster names, primary keywords, supporting keywords, recommended page types (pillar vs supporting), suggested titles, and traffic estimates. The output is formatted so it can be moved directly into a content calendar or project tracker.

The flow can be extended into a full SEO planning and execution system. Add integrations to Google Search Console and analytics to validate opportunities against existing performance, and to your CMS or project tracker to create tasks automatically. Store clusters in a database for versioned strategy updates, and add guardrails for taxonomy (topic categories, funnel stages, ICP segments). You can also generate content briefs per cluster (outline, internal links, FAQs) and create A/B variants for titles and meta descriptions. Advanced setups can incorporate competitor gap analysis, detect cannibalization against existing URLs, and continuously refresh clusters as SERPs and demand shift.
