Build a SEO Rank Tracker
Track keyword positions daily with Google SERP API.
Architecture
Daily cron job → Google SERP API → SQLite/Postgres → simple Flask dashboard showing rank history per keyword.
Why build instead of buy
Commercial rank trackers cost $200+/mo. Using our SERP API at Pro tier ($9.99/mo) handles 10K queries — enough for 333 keywords daily.
