SEO Rank Tracker & Keyword Generator
Cluster a seed keyword by intent, check Google rank, and export CSV with your own API keys.
About this app
Northline Rank Lab is a Next.js app for US keyword research and rank checks. Enter a seed keyword and the app builds long-tail phrases, questions, and intent clusters (research, comparison, purchase, and navigational). It merges a built-in expansion list with Google autocomplete. If you add an OpenAI-compatible key, it also asks your model for more phrases and keeps the result when the model fails. The rank checker looks up a domain with your SerpAPI key or your DataForSEO login. Results and keywords stay in your browser and export to CSV. Keys are typed into Settings, stored in localStorage, and sent only to the provider you chose through the local server. This package does not include provider credits, search volume, or a rank database.
Problem it solves
Small sites need a repeatable way to turn one seed keyword into clustered phrases and to record where their domain ranks, without handing API keys to a hosted SEO suite.

Known issues
Rank checks depend on your SerpAPI or DataForSEO quota and only reflect what that provider returns. Google autocomplete is a public suggestion endpoint and can rate-limit. The sample workspace is labeled example data, not a live ranking.
