Is it relevant/interesting to add the same keyword in different variations: "keyword" and [keyword]?
Or is "keyword" enough?
Yes, because they serve different purposes.
1. Phrase match ("keyword")
→ Shows your ad when the query contains the meaning of your keyword.
Example: "digital marketing course" can trigger ads for:
- best digital marketing course online
- digital marketing course near me
2. Exact match ([keyword])
→ Shows your ad when the query closely matches your keyword.
Example: [digital marketing course] will mostly show for:
- digital marketing course
- digital marketing courses
By using both, you get a balance:
Phrase match = reach & new opportunities
Exact match = control & precision
Example:
If your main keyword is “CRM software”:
Add "CRM software" → to capture searches like best CRM software for small business
Add [CRM software] → to make sure you also show for high-intent exact searches like CRM software
To conclude, "keyword" alone isn’t always enough. For a smart strategy, combine "keyword" (phrase) + [keyword] (exact) to cover both discovery and profit-focused queries.
Hope this helps.
