Start with a broad 2–4 word topic related to your video. Think about what your target viewer would type into YouTube. Keep it simple: "how to make pizza", "beginner yoga", "python tutorial".

Type your seed keyword into YouTube's search bar and pause. Note all autocomplete suggestions — these are real searches. Try adding letters (a, b, c) after your keyword to surface hundreds more variations. Use KeywordTool.io or Keyword Tool Dominator to automate this at scale.
Use VidIQ, TubeBuddy, or Ahrefs to check monthly search volume and competition score.
Golden rule for new channels (under 10K subscribers): Target 300–5,000 monthly searches + competition/difficulty score under 40. High-volume keywords (50,000+ searches) are dominated by large channels you cannot compete with yet.
Go to Google Trends, change the filter to YouTube Search. Confirm interest is stable or rising — never target declining keywords. Compare your top 2–3 keyword options to find which has the best momentum. If You are searching for digital marketing jobs? Find the latest opportunities and tips: Digital Marketing Jobs
