Big keyword lists feel productive. In practice nobody reads a 500-row rank report, and the 10 searches that bring buyers get lost.
Pick the 10 that pay
Choose searches where the person is ready to act: "best [thing] for [use]", "[thing] near me", "[you] vs [rival]", "[thing] price". If ranking #1 wouldn't make you money, drop it.
Watch them against one rival
Your position alone tells you little. Watching who's ahead, keyword by keyword, tells you where to push.
Check weekly
Daily moves are noise. Weekly moves are trends. That's why Keyword Battle is 10 keywords, one rival, and a Monday email when positions move.
