Google Ads and Current Advertising Cost Optimization Techniques
Google Ads Challenges and Opportunities in Advertising
Google Ads in the context of increasingly difficult and competitive advertising, marketers need not only to optimize advertising but also to optimize costs by using budgets more effectively, targeting potential customers correctly, and maximizing conversion rates. This article will introduce you to many Google Ads advertising techniques that have been proven effective in practice.
Understanding Google Ads Advertising Costs and Key Metrics

CPC (Cost Per Click)
- The average cost you pay for each click on your ad. A high CPC can be driven by competitor bidding, keywords, landing page quality, etc.
CPA (Cost Per Action)
- The cost per desired action (such as placing an order, registering, contacting). Optimizing CPA helps you assess the true effectiveness of your advertising.
ROAS (Return on Ad Spend)
- The return on advertising spend. The higher ROAS > 1, the better. Helps you identify which strategies are profitable.
Key Optimizations to Consider in Google Ads
Optimizing Costs from a Campaign Perspective

Allocate budget according to campaign and objective: Clearly defining objectives (such as sales, increased traffic, lead collection) helps allocate budgets flexibly to effective campaigns based on ROAS.
Choose the right campaign type (Search, Display, Video...): Optimize Search for people who already have a need. Combine Retargeting with Display/Video to stay top-of-mind and increase awareness.
Optimize Google Ads by Geography, Device, and Audience
- Devices, regions, or audiences with low performance should be limited or have their ads turned off. Leveraging geotargeting helps increase conversion rates.
Optimizing Campaign Structure to Save Budget in Google Ads
- Categorize campaigns by objective: Create separate campaigns for each objective: conversions, visits, calls, or remarketing. This helps Google optimize effectively for each campaign.
- Divide ad groups by specific keywords: Use SKAG (Single Keyword Ad Group) to group keywords corresponding to ad copy. This technique improves quality scores, increases click-through rates, and reduces CPC.
- Prioritize high-converting keywords: Analyze keywords with the best ROI in the past and increase investment in them. At the same time, eliminate or reduce budgets for expensive but ineffective keywords.
Optimizing Smart Bidding Strategies
- Apply Smart Bidding strategies: Utilize tools like Maximize Conversions, Target CPA, or Target ROAS for Google to automatically adjust bids based on user behavior data.
- Adjust bids by time and geographic location: Increase or decrease bids based on time of day, day of the week, or regions that deliver higher performance. This is a way to optimize cost allocation based on customer behavior.
- Use ad scheduling settings: Avoid running ads 24/7 if it's not necessary. Focus the budget on the times when customers are most likely to convert.
Optimizing Ad Copy to Improve Conversion Efficiency
- Write compelling ad content that matches search queries: Ensure keywords appear in the title and description. Use clear CTAs like "Sign up now", "Get a free quote", "Buy today".
- Leverage ad extensions: Extensions such as sitelinks, callouts, structured snippets, and call extensions help expand ads, increase click-through rates, and improve quality scores.
- A/B test multiple ad copies: Always experiment with two or more versions of the ad to find the most effective content. Use data to make decisions to change.
Optimize Landing Page to Reduce Costs and Increase Conversions
The landing page needs to have a fast loading speed, be optimized for mobile, and have a clear CTA. A concise layout, chatbot integration, short forms, and synchronization with advertising keywords help increase Quality Score and reduce CPC.
Analyze data and adjust continuously: Use Google Analytics, Tag Manager, Data Studio to track and analyze. Continuously A/B test ad copy, optimize landing pages, and find the best version.
