Greetings I had watched several videos on how to find niche but get more confused. All I need to know is how to generate ideas for niche research or Seed Keywords so I can extract more related keywords. Mostly website had mentioned DIY, Baby, Health, Fitness, Weight, Tech as Niche Ideas I believes these are not refined one. E.g. Tech can break down in several things APK Niche, IOS Tweak, IOS Features etc.
Please suggest me I a new guy exploring the SEO world. Thanks.
