Nearly 45% of Google Ads accounts struggle with low-performing keywords that drag down campaign efficiency, according to industry audits. If you’ve ever wondered why certain keywords never gain traction—despite well-written ads and a healthy budget—you’re not alone. Many advertisers face the same issue when their campaigns stall because Google labels certain terms as “low search volume.”
These low-activity keywords can leave you frustrated, especially when they seem relevant to your product or service. Partnering with an expert SEO services company can help diagnose keyword performance issues, but understanding the root cause is the first step.
At the center of the problem is your keyword quality score—Google’s rating of how relevant and useful your keywords, ads, and landing pages are to users. Advertisers often worry that low search volume may hurt this score, limit impressions, or reduce ad visibility. That concern is valid, but the relationship between search volume and Quality Score isn’t always as straightforward as it looks.
So, do low search volume keywords affect quality score? And if they do, how significant is the impact?
In this guide, you’ll learn how Quality Score actually works, what low search volume means from Google’s perspective, and why some keywords stay stagnant even with strong campaign setups. More importantly, you’ll discover practical ways to increase the quality score of a low performing keyword, improve relevance, and strengthen campaign performance without wasting time or budget.
A keyword quality score is Google’s measure of how relevant and useful your keyword, ad copy, and landing page are to users. It’s scored on a scale from 1 to 10, with 10 being the highest. Three main factors influence this score:
Google evaluates keyword performance continuously, using historical and real-time data to adjust scores. Even if a keyword is technically accurate, poor CTR or an irrelevant landing page can lower its quality score.
Quality Score isn’t just a number—it directly impacts your ad rank and cost per click (CPC). A higher score means:
On the flip side, low-quality scores increase CPC, limit ad visibility, and reduce the effectiveness of your campaigns. Understanding and optimizing keyword quality score is essential to maintain strong ad performance and get the most from your Google Ads investment.
Google labels keywords as “low search volume” when they receive too few searches to generate meaningful performance data. While Google doesn’t disclose exact thresholds, generally, keywords with very limited or sporadic search traffic fall into this category.
These terms often appear in niche markets, long-tail queries, or highly specific product or service searches. When a keyword is marked low search volume, it won’t trigger ads until search traffic increases, ensuring your campaigns focus on terms that have enough activity to measure performance accurately.
For keywords with extremely low search volume, Google does not actively calculate a quality score because there isn’t enough data to evaluate CTR, ad relevance, or landing page performance. This means that, technically, low search volume alone doesn’t hurt your keyword quality score.
However, low-volume keywords can have indirect effects on campaign performance:
Low search volume becomes a real issue when your campaigns rely heavily on these keywords for traffic or conversions. At that point, the lack of data prevents you from making meaningful optimizations, making it harder to increase quality score of low performing keyword and achieve strong campaign results.
For low search volume keywords, the direct impact on Quality Score ads is minimal. Since Google doesn’t calculate Quality Score without sufficient data, these keywords won’t immediately lower your score. In other words, until your ads start receiving impressions and clicks, the effect is largely neutral.
The indirect impact, however, can be significant:
Even though the keyword itself isn’t penalized, its inactivity can prevent your campaign from reaching full performance potential.
Low search volume keywords can influence ad rank and bidding strategy indirectly. Here’s how:
Understanding these indirect effects is key to managing low search volume keywords and finding ways to increase quality score of low performing keyword through strategic campaign adjustments and targeted optimizations.
Including too many low search volume keywords can lead to keyword bloat, where inactive or rarely triggered terms clutter your campaigns. This reduces focus and makes it harder for Google to evaluate ad relevance accurately. Large ad groups with mixed or low-performing keywords can dilute signals, lowering the efficiency of otherwise strong campaigns.
Overloaded campaigns also make management more difficult. It becomes challenging to identify which keywords are driving results and which are holding your quality score ads back. Maintaining tightly focused ad groups improves clarity, relevance, and overall campaign performance.
Low search volume keywords often reflect queries that don’t align with actual user behavior. Even if the keywords seem relevant on paper, minimal search activity means fewer impressions and clicks. With limited data, it’s harder to prove relevance to Google, and your ads may underperform compared to terms with higher traffic.
Fewer impressions also mean fewer opportunities to test and optimize your ad copy or landing pages. Without this feedback loop, even potentially valuable keywords remain stagnant, making it harder to increase quality score of low performing keyword and drive meaningful campaign results.
To improve keyword quality score, start by refining your ad copy to closely match the search intent behind each keyword. Ads should clearly reflect the terms users are searching for, creating a strong connection between query and offer.
Consider using Single Keyword Ad Groups (SKAGs) or SKAG-like structures. By grouping one keyword per ad group, you can tailor ad copy more precisely, improving relevance and increasing the chances of clicks. This targeted approach helps Google recognize the value of your ads and boosts Quality Score.
Your landing page plays a critical role in quality score ads. Ensure pages load quickly, display content clearly, and align with the keyword’s intent. Strong calls-to-action (CTAs) guide users to take the desired action, while optimized content keeps them engaged.
Improving user experience—reducing bounce rates, simplifying navigation, and making pages mobile-friendly—signals to Google that your ads provide real value, helping to increase the quality score of low performing keyword over time.
Expected Click-Through Rate (CTR) is a major component of Quality Score. You can improve it by:
These strategies provide more performance signals to Google, allowing your low-performing keywords to gain traction.
Not all low search volume keywords are worth keeping. Consider removing or replacing terms that consistently underperform. When expanding, use broader match types carefully to capture related searches without losing relevance.
Identify close variants with slightly higher search volume that still align with user intent. By focusing on terms that deliver traffic while maintaining relevance, you can strategically increase the quality score of a low performing keyword and make your campaigns more efficient and profitable.
Grouping related keywords into smaller, focused ad groups improves ad relevance and makes it easier for Google to evaluate performance. Tighter groups allow you to craft highly targeted ad copy for each keyword theme, increasing CTR and giving your low-performing keywords a better chance to show results.
For keywords with very low search volume, consider using broad match paired with Smart Bidding. This approach allows Google to find relevant variations of your keywords while optimizing for conversions. It ensures that even low-volume terms have an opportunity to trigger ads without wasting budget on unrelated traffic.
Monitor your search terms report to identify which low search volume keywords are actually generating impressions and clicks. Replace underperforming terms with higher-volume variants or adjust match types to capture more relevant searches. Regular reviews help you maintain focus on keywords that contribute to campaign success and increase quality score of low performing keyword.
Too many low-volume keywords can clutter campaigns and dilute performance signals. Remove inactive or irrelevant keywords to streamline ad groups, improve management efficiency, and allow Google to better evaluate and rank your active terms. Focusing on quality over quantity ensures your campaigns remain effective and your quality score ads stay strong.
Low search volume keywords do not directly affect quality score because Google cannot calculate it without sufficient impressions and clicks. However, they can have indirect effects by cluttering campaigns, diluting ad relevance, and limiting optimization opportunities.
If a keyword consistently receives no impressions or clicks, it’s often best to pause or replace it with higher-volume or more relevant variants. Focus on terms that provide data and allow for optimization to improve campaign efficiency and overall keyword quality score.
Quality Score relies on user interaction data, so it cannot improve without impressions. To increase it, your ads need enough visibility and clicks for Google to evaluate CTR, ad relevance, and landing page experience. Using strategies like tighter ad groups, relevant ad copy, and optimized landing pages can help low-performing keywords gain traction and improve over time.
Conclusion
Industry studies show that over 60% of Google Ads campaigns underperform due to poorly optimized or low-traffic keywords. While low search volume keywords don’t directly lower your keyword quality score, they can indirectly affect overall campaign performance by limiting data, reducing CTR opportunities, and diluting ad relevance.
To improve results, focus on intent-driven keywords and make relevance a priority. Optimizing ad copy, refining landing pages, and restructuring ad groups can help you increase quality score of low performing keyword while maximizing campaign efficiency.
Take action today: review your campaigns, remove or replace underperforming terms, and implement targeted strategies to optimize ad structure and keyword strategy. Doing so will enhance visibility, improve ROI, and ensure your Google Ads campaigns deliver measurable results.
