New advertisers often use these words interchangeably, but in Google Ads they mean two very different things.
| Keywords (the input) | The words you give to Google: your best guess at what people search for. | You order "steak" from the menu. |
| Search terms (the output) | The exact words a user types into Google before clicking your ad. | The chef brings you a "ribeye with peppercorn sauce." It is technically what you asked for, but it might not be exactly what you expected. |
Unless you use strict [exact match] keywords, your keyword and the user’s search term will rarely be identical.
Example scenario:
Your keyword: "cleaning services" (phrase match)
Actual search terms that trigger your ad:
| Home cleaning services near me | Good |
| Cheap cleaning services | Okay |
| Pool cleaning services | Bad, if you only clean houses |
| How to start a cleaning services business | Wasted money |
The lesson: You bid on the keyword, but you pay for the search term. The gap between the two is where budget gets wasted.
The main campaign overview doesn’t show these details. To see what you are really paying for, open the search terms report.
In the left menu, go to Insights and reports › Search terms.
Review the list: it shows the exact queries users typed before clicking.
How to use this report:
Find gold: If a search term brings conversions but isn’t a keyword yet, add it as an exact match keyword so you can bid on it directly.
Remove waste: If you see irrelevant terms (like "pool cleaning" in the example above), select them and add them as negative keywords.
Click fraud bots can use legitimate-looking search terms to blend in. They might search for your exact high-value keyword (e.g., "emergency plumber") so their traffic looks real.
Why manual review isn’t enough: You see "emergency plumber" in your search terms report and it looks perfect. But you can’t see who typed it.
The solution: While you review your search terms for relevance (words), ClickSambo checks the traffic for validity (behavior) and blocks bad actors, even when they use the "right" words.
