What is optimizing your Google Ads?

Google Ads optimization is the systematic improvement of campaign settings and elements to increase campaign performance and reduce costs. Google Ads optimization applies to search ads, display campaigns, and Shopping campaigns.

The 5 core elements of Google Ads campaign optimization are:

• Refining keywords: adding negative keywords and expanding keywords with high purchase intent terms

• Improving ad relevance: writing compelling ad copy and adding ad extensions

• Adjusting bid strategies: choosing between manual bidding and automated bidding strategies based on campaign goals

• Optimizing landing pages: maintaining relevance and improving load times for higher conversion rates

Setting up conversion tracking: measuring which campaigns, ad groups, and keywords generate direct business results

Why optimizing Google Ads is essential for your ROI

Google Ads campaigns without optimization waste budget on searches that do not convert. A non-optimized Google Ads campaign displays ads on broad search terms, to the wrong audiences, and at times when the likelihood of conversion is low. Higher cost per acquisition (CPA) and a lower return on ad spend (ROAS) are the direct consequences.

Optimized Google Ads campaigns target the budget on users with high purchase intent. More leads and revenue at lower cost per acquisition are the measurable results.

The quality score plays a central role in campaign performance. Google's quality score is a number from 1 to 10 based on 3 components: the expected click-through rate of the ad, ad relevance to the search query, and user experience on the landing page.

A higher quality score leads to a better ad position and lower cost per click (CPC). A low quality score increases cost per click and lowers ad position, even with a high bid. A quality score of 8 or higher is the target level for structurally profitable campaigns.

Kolibrie, a staffing client of Aizy, achieved a 109% revenue growth in Q4 2025 by scaling up carefully. The ROAS slightly decreased from 19 to 17 but remained at a healthy return level while the absolute result more than doubled. Targeted Google Ads optimization on bidding strategy and audience targeting produced that result.

The 11 best strategies for Google Ads campaign optimization

1. Keyword research and keyword expansion

Effective Google Ads campaigns focus on keywords with low to medium search volume and high purchase intent. Google Keyword Planner provides insight into how people search for terms that relate to the product or service: search volume per keyword, level of competition, and related search terms.

Campaigns on your own brand name or company name form a separate category. Competitors often bid on others' brand names. A brand campaign protects brand awareness and produces cheap clicks.

The 3 keyword options (match types) and their application:

• Broad match: the widest reach, the highest risk of irrelevant traffic. Use only in combination with an extensive negative keyword list

• Phrase match: ads appear on searches that contain the keyword phrase in the specified order. A balance between reach and relevance

• Exact match: ads appear only on the exact search query or close variants. Highest relevance, lowest reach

2. Adding negative keywords

Negative keywords filter irrelevant searches that consume budget without any conversion chance. The search terms report in Google Ads shows the exact search queries that trigger ads. Common categories of negative keywords include:

• Free-related searches: "free", "no cost", "download for free"

• Informational searches without purchase intent: "wiki", "definition", "what is"

• Irrelevant industries or locations that fall outside the service area

Negative keywords are the fastest way to recover wasted advertising budget.

3. Improving ad copy and calls to action

Effective ad copy names a direct benefit for the searcher and aligns with the search intent behind the keyword. Headlines include the primary keyword. Calls to action are specific: "Request a quote", "Order today" and "View the range" generate a higher CTR than generic variants like "Click here". Specific numbers and unique selling points in the ad copy attract potential customers with purchase intent and filter out unsuitable clicks, such as "Delivery time 24 hours" or "From €49".

Google Ads responsive search ads accept up to 15 headlines and 4 descriptions. Google automatically tests which combinations generate the best click-through rate. At least 3 ad variations per ad group provide the system with enough test material.

4. Adding ad extensions

Ad extensions increase the ad in the search results and provide additional information to potential customers, at no extra cost per impression. The 3 most effective extension types for Google Ads optimization are:

• Sitelink extensions: additional links to specific pages, such as product categories, the contact page, or the pricing page

• Highlight extensions: short unique selling points such as "Free shipping", "30 days return", or "Certified installer"

• Call extensions: the phone number directly visible in the ad, particularly effective for lead generation on mobile

Ad extensions increase the quality score and improve the ad position without raising the bid.

5. Refining audience targeting and remarketing

Google Ads offers 3 primary audience targeting options for more targeted campaigns:

• Remarketing Lists for Search Ads (RLSA): higher bids on previous website visitors who are searching again on relevant terms

• Customer Match: building audiences based on email addresses of existing customers for retargeting or lookalike audiences

• In-market audiences: targeting users that Google classifies as actively searching for products or services in a specific category based on their search behavior

Users who have previously interacted with the brand or website convert at lower CPA than new visitors on average.

6. Optimizing bid strategies

The choice between manual bidding and automated bidding strategies determines how much control the advertiser has versus how much the bidding system learns from conversion data.

Automated bidding strategies perform better with at least 30 conversions per month as learning data. New campaigns start on manual CPC or Maximize clicks. Switching to Target CPA or Target ROAS is effective once the required conversion data is available.

7. Refining location targeting

Google Ads displays ads by default in the specified target region AND to users who show interest in that region. Refining location targeting to the exact geographic areas where customers are located reduces wasted reach immediately. Bid adjustments increase bids in well-performing regions and lower bids in regions with high costs and low conversion rates.

8. Setting up ad scheduling

Ad scheduling (dayparting) limits the impression period to the hours and days when the audience converts. The performance segment "Hour of the day" and "Day of the week" in Google Ads shows conversion rates per time slot. Disabling ads during time slots with many clicks but zero conversions immediately lowers the CPA.

9. Optimizing landing pages

The landing page, also known as the destination page, largely determines whether a click converts. An effective landing page aligns with the ad promise, loads within 3 seconds, and contains a clear call-to-action above the fold. Every additional second of load time decreases the conversion rate by an average of 7%.

Forms with more than 5 fields reduce the fill-out rate measurably. Landing page quality is a direct component of the quality score: a poor destination page raises cost per click and lowers the number of impressions, even on a limited budget.

10. Setting up conversion tracking correctly

Conversion tracking is the foundation of data-driven Google Ads optimization. Without proper tracking, Smart Bidding operates on incomplete data, and campaigns make suboptimal decisions. The 3 conversion types that should be tracked at a minimum are: purchases or leads, form submissions, and phone calls. Google Tag Manager centralizes the implementation of conversion tags and links Google Ads to Google Analytics 4 for complete insight into the customer journey.

11. A/B testing of ads

Campaigns with only one ad variant per ad group miss the chance to structurally improve CTR and conversion rate. At least 3 active ad variants per ad group give Google enough data to identify the best-performing combination. Test one variable per iteration: headline, description, or call-to-action. Manual analysis of performance data after a minimum of 200 impressions per variant provides statistical certainty about the winner.

Google Ads optimization score and recommendations

The optimization score in Google Ads is a percentage from 0 to 100% that estimates how well campaigns perform compared to Google's best practices. The optimization score is based on campaign settings, bidding strategies, keywords, and ad quality.

Not all recommendations from Google align with every business goal. Google's recommendation system is designed to maximize campaign reach and ad spend, not to maximize profitability per euro. Some recommendations introduce new features that have not yet been tested on the own Google Ads account. Evaluate each recommendation on three criteria before applying it:

• Accept recommendations that improve the quality score, add negative keywords, or strengthen conversion tracking

• Critically review recommendations that increase the budget, expand broad match, or add new keywords outside the core strategy

• Reject recommendations that broaden audience reach at the expense of targeting precision or that enable automatic campaign changes without prior validation

The "Automatically apply recommendations" feature makes changes without manual approval. Activate automatic application only for recommendations that have been validated and whose impact has been positively established. Check automated changes weekly in the change history.

How long does it take for Google Ads optimization to yield results?

The first improvements after targeted optimization are visible within 2 to 4 weeks. Structural performance improvements require a minimum of 60 to 90 days of data for automated bidding strategies to learn from conversion patterns. Seasonal campaigns require at least one full seasonal cycle of data for accurate bidding optimization.

Optimizing Google Ads is not a one-time action. Regularly reviewing campaign performance in analysis forms the basis for structurally better results. Coral & Fish, a pet and lifestyle eCommerce client of Aizy, achieved a 73% revenue growth in Q4 2025 in a period of 8 weeks through targeted optimization of bidding strategy and audience segmentation.
