- Non-Branded Keywords:
- Keywords that do not include a brand name (e.g., “running shoes”).
- Used to attract users searching for products or services without a brand preference.
- Informational Keywords:
- Keywords that indicate the searcher is looking for information (e.g., “how to tie running shoes”).
- Often in the form of questions or general knowledge queries.
