GrowthBar
GrowthBar is an AI SEO tool that generates keyword research, competitor keyword gaps, and full blog articles from a single keyword, plus basic rank tracking across a handful of sites. It has been acquired by SEOptimer and is being merged into that platform, though it still sells standalone plans.
GrowthBar's own current page names its sources outright — Google Ads' keyword tool, SpyFu's keyword database, and OpenAI's GPT-3 — so every piece is a rented third-party feed plus a hosted model, not anything GrowthBar built or crawled itself.
What you lose building it yourself
- ✕Blog-to-audio/video conversion built into the same dashboard
- ✕One dashboard tracking keywords across up to 25 sites at once
Why people still pay
GrowthBar bundles keyword data licensed from SpyFu and Google Ads, scheduled rank tracking across dozens of sites, and blog-to-audio/video conversion into one dashboard — replicating all of it yourself means paying for (or building around) the same third-party data feeds plus maintaining several separate integrations, not just running one prompt.
BUILD YOUR OWN · WEEKEND SCOPE
An AI coding tool can wire a keyword-data API to a hosted AI model to reproduce the keyword-research-to-blog-draft flow in a weekend; matching the blog-to-audio/video conversion and multi-site rank tracking takes separate integrations on top of that core loop.
StackA keyword-data API such as DataForSEO or SerpApi for search volume and competitor gaps (renting the same kind of feed GrowthBar licenses from SpyFu and Google Ads) · a hosted LLM API for blog-post drafting · a scheduled script and a spreadsheet or SQLite database for rank tracking.
Build a Python script that takes a target keyword, fetches search volume and the top-10 ranking competitor URLs via a keyword-data API (e.g. DataForSEO), pulls each competitor's page headings, and sends the keyword plus those headings to a hosted AI model with instructions to write a complete, SEO-structured blog post (H1, H2s, meta description) in Markdown. Cap each run to one article and print the model's token usage so cost stays visible.
Similar tools
Free alternative: Google Keyword Planner — free and official for raw keyword search-volume data; it has no competitor keyword-gap mining (SpyFu's paid job here), no AI blog drafting, and no rank tracking.
Vendor's own claim
"Our data is aggregated from proprietary algorithms and trusted data providers including industry-leading Google Ads tool, SpyFu and OpenAI's natural language model, GPT-3."

QUESTIONS
Is GrowthBar still a standalone product?
Its own current page says it was acquired by SEOptimer and is being merged into that platform, though standalone plans were still being sold as of this review.
Does GrowthBar use its own AI model?
No — its own page names OpenAI's GPT-3 directly as the content-generation model, alongside licensed data from SpyFu and Google Ads.
Is there a free tier?
No — a 7-day free trial only, then plans start at $36/month (or $20.30/month billed annually).
