What Is a Negative Keyword?
In Google Ads campaigns, negative keywords are the way you tell the system the search queries you don't want your ad to show for. If you sell 'shoes', for instance, you stop your ad from appearing on unrelated searches like 'free shoes' or 'shoe repair'.
This small-looking setting is actually your budget's most critical defender. Google Ads runs on broad match by default and can spend your budget on a much wider audience than you think.
The Reality Behind the Numbers
Industry averages show that in an un-optimized Google Ads account 28–43% of total clicks come from irrelevant queries. For an account spending ₺10,000/month that's ₺2,800–₺4,300 in wasted budget.
First-month data from MoofSearch customers shows an average of 36% budget savings. The exact number varies with campaign size and industry.

Which Terms Should I Add as Negatives?
When building a negative keyword strategy focus on these categories first:
- Free: queries containing 'free', 'no-cost', 'gratis' — users with no purchase intent
- How-to / DIY: 'how to', 'do it yourself', 'DIY' — information seekers, not buyers
- Competitor brand names: especially if you run branded ads, add competitor names as negatives
- Unrelated products/services: similar-sounding products in a different category
- Out-of-area queries: if you only serve Istanbul, exclude 'Ankara', 'Izmir' etc.
Match Types: Broad, Phrase, Exact
Negative keywords can be added in three different match types. Broad match blocks all searches where the words appear in any order. Phrase match blocks searches where the words appear in that order. Exact match only triggers when the query matches word-for-word.
In most cases broad-match negative gives the widest protection. But for polysemous words like 'watch', broad match can block queries you actually want. Evaluate each term and pick the most appropriate match type.
Automatic Detection with AI
Manually adding negative keywords is time-consuming and error-prone. In large accounts with thousands of search terms, reviewing every query can take days.
MoofSearch automates this process. It compares each query against purchase intent, industry context and campaign goals, and lists the candidates for negatives within seconds. You can bulk-add with one click and send your decisions back to the AI as feedback.
💡 With MoofSearch you can analyze 1,000 search terms in about 4 minutes on average.
