Common Keyword Mistakes

Mistake 1: Keyword Stuffing

Don't do this:

Weight loss weight loss tips weight loss workout
weight loss motivation weight loss for beginners

Platforms penalize this. Write naturally.

Using popular keywords unrelated to your content:

  • Attracts wrong audience
  • Hurts engagement rate
  • May violate policies

Mistake 3: Only Short-Tail Keywords

TypeExampleCompetition
Short-tail"Fitness"Very high
Long-tail"Home workouts for beginners over 40"Lower

Long-tail keywords have less competition and higher intent.

Mistake 4: Never Updating

Keywords change. Review quarterly:

  • Add trending terms
  • Remove underperformers
  • Adjust for seasonality
