1. Keyword research

You spend hours crafting killer content, but nobody finds it.

Not ideal, right?

Keyword research helps you find high-volume, low-competition keywords that drive organic traffic.

A Semrush study shows that 3-3.5 pages are visited per session when a user lands from a search. So, having a comprehensive keyword research tool is crucial for organic growth.

Limitations

• The tool can overwhelm new users with all this data, causing information fatigue.

🧑‍⚖️ Verdict

Semrush wins the first round. ✌️
