What is Negative Keyword?

Why It Matters

Negative Keywords matter because broad or phrase-match keyword targeting almost always captures some volume of searches that look relevant on paper but aren't, wasting budget on clicks that were never going to convert. A campaign targeting the keyword shoes, for instance, might also trigger for free shoes or shoe repair, neither of which represents a buyer for a retail ecommerce store. Adding those as negative keywords stops the ad from showing for that traffic at all, rather than paying for the click and then losing the conversion anyway. Over time, a well-maintained negative keyword list is one of the simplest, lowest-effort ways to improve both CPC and conversion rate, since it directly reduces wasted spend on searches that were never going to convert regardless of landing page quality.

Example

An ecommerce store selling premium running shoes notices its campaign is triggering on searches for shoe repair and used shoes, neither of which fit its business. Adding repair and used as negative keywords stops the ad from showing on those searches going forward, immediately reducing wasted spend without needing to change the core keyword targeting at all.

Frequently Asked Questions

• How is a Negative Keyword different from simply narrowing keyword match type?

  Narrowing match type changes how closely a search must match the target keyword itself. A negative keyword specifically blocks the ad from showing for particular unwanted terms, even if the overall match type would otherwise allow it.

• Do Negative Keywords cost anything to add?

  No, adding negative keywords doesn't cost anything directly, and it typically reduces wasted spend, making it one of the lowest-risk optimizations available in a paid search account.

• How does a team find which Negative Keywords to add?

  Reviewing the search terms report, which shows the actual queries that triggered an ad, is the most common way to identify irrelevant traffic and decide which terms to exclude going forward.

• Can Negative Keywords improve Quality Score?

  Indirectly, yes. By filtering out irrelevant traffic, negative keywords tend to improve click-through rate and conversion rate on the remaining traffic, both of which factor into Quality Score over time.

• Are Negative Keywords a one-time setup or an ongoing process?

  Ongoing. Search behavior shifts over time, so most accounts benefit from periodically reviewing the search terms report and updating the negative keyword list rather than setting it once and leaving it untouched.
