Google advertising (also known as Google Ads) is an effective way to reach potential customers exactly when they are searching for a product or service. Done correctly, it quickly brings visibility, increases traffic, and above all increases sales. Google Ads is especially effective because it reaches people specifically at the decisive stages of the buying process, when they are actively looking for a solution to their problem.
This article goes through best practices for Google Ads and concrete strategies for reaching buyers at exactly the right moment and turning them into customers.
1. Visibility at the right moment: Intent-based advertising
When a user searches on Google, they are often already ready to act: compare, contact, or buy. Google Ads brings your company into view at that exact decisive moment. This is the greatest strength of Google Ads: intent meaning purchase intent already exists.
Examples of purchase intent strength in different search types:
- ‘Online store design price’ - Weak purchase intent. The user is still comparing and gathering information. CPC €1-€2, conversion rate 0.5-1%.
- ‘Ecommerce platform in Finland’ - Medium purchase intent. The user is researching options. CPC €2-€4, conversion rate 1-2%.
- ‘Order ecommerce design Helsinki’ - Strong purchase intent. The user is ready to make a decision. CPC €4-€8, conversion rate 3-5%.
Focus on high-intent keywords: Prioritize keywords that include words referring to buying or action: ‘buy’, ‘order’, ‘book’, ‘request a quote’, ‘price’, ‘near me’. These convert 3-5x better than more generic keywords.
Practical example: A company offering heat pump maintenance focused its budget on keywords such as ‘heat pump maintenance [city]’ and ‘heat pump broke down’. These are high-intent searches where people need help now. Result: 8.2% conversion rate and €35 CPA, while more general keywords produced a 1.5% conversion rate and €120 CPA.
2. You pay only for results, but optimize Quality Score
Google Ads works on a click-based model (CPC), meaning you pay only when someone clicks your ad. This makes it cost-effective, especially when advertising is well targeted and conversion points are in place. But the CPC model alone is not enough: if Quality Score is poor, you may pay 2-3x more per click than competitors.
What is Quality Score? Google evaluates the quality of each keyword on a scale of 1-10. It consists of three factors:
- Expected CTR: Is your ad attractive and relevant to the keyword?
- Ad relevance: Does your ad text match the keyword’s content?
- Landing page experience: Is your page high-quality, fast, and relevant?
The impact of Quality Score on costs: Example: Keyword ‘marketing agency Helsinki’. Competitor A: Quality Score 4, CPC €6.50. Competitor B: Quality Score 9, CPC €2.20. Same click, but B pays 66% less. This means that with the same budget, B gets 3x more clicks.
How to improve Quality Score?
- Write ad texts that include the keyword and match the search intent
- Create dedicated landing pages for each ad campaign; do not send everyone to the homepage
- Optimize page load speed (target under 3 seconds)
- Make sure the landing page has a clear CTA (Call to Action) and contact form
3. Effective targeting: Location, time, and device
You can target your ads precisely by location, keywords, device type, and time of day, for example. This makes ads appear to the right audience at the right time. This is critical: do not waste budget on the wrong audiences or the wrong times.
Location targeting: When operating locally (for example a carpenter in Tampere), ads should be limited to only a 20-30 km radius from Tampere city center. Advertising to all of Finland wastes budget on people who cannot be served. Proper location targeting can reduce unnecessary clicks by 40-60%.
Ad Scheduling: Analyze when your customers are most active. In B2B services, the best times are often Mon-Fri 8-17. For consumer services, evenings and weekends can be effective. Example: A restaurant client increased budget Fri-Sat 16-20 (when people were booking tables) and reduced Tuesday morning budget. Result: 25% better ROAS.
Device targeting: 60-70% of searches come from mobile devices, but conversion rate is often better on desktop (especially in B2B). Analyze data and adjust bids by device. If mobile produces leads 50% more expensively, reduce mobile bids by 20-30%.
4. Measuring and optimizing results - data guides decisions
Google Ads offers comprehensive tools for measuring results. You can see exactly which keywords, ads, and campaigns produce results, and continuously optimize based on data. But simply looking at the data is not enough; you need to act on it.
The most important metrics I track:
- Impressions: How many times your ad was shown. If too few, raise bids or improve Quality Score.
- CTR (Click-Through Rate): How many viewers click. Target: 3-8% (varies by industry). If under 2%, your ad is not attractive enough.
- CPC (Cost Per Click): Average price per click. Compare with competitors and optimize Quality Score to lower it.
- Conversion Rate: How many clickers become customers/leads. Target: 2-5%. If under 1%, the landing page is not working.
- CPA (Cost Per Acquisition): How much one lead/customer costs. This must be lower than the revenue from the customer.
- ROAS (Return on Ad Spend): How many euros you get back per ad euro. Target: 4-6x or more.
Optimization practices I use weekly:
- Negative keywords: Add keywords weekly that bring unnecessary clicks. For example, if you sell paid services, add ‘free’ as a negative keyword.
- Pause poor keywords: If a keyword has generated 50+ clicks without a single conversion, pause it and move the budget to working ones.
- Raise bids for well-performing keywords: If a keyword produces 6x ROAS, increase its budget by 20-30%; it scales success.
- A/B test ad texts: Always test 2-3 ad versions at the same time. Let them run for 2 weeks, remove the weakest, and create a new challenger.
5. Quick to start, but do not skip planning
Google Ads can be started quickly. Within a few days, you can appear in potential customers’ search results, especially if your website supports the goals of advertising well. But speed must not mean carelessness.
Checklist before launching a campaign:
- Conversion tracking installed: Google Ads Conversion Tracking must be in use; otherwise you cannot see which campaigns produce results.
- Landing pages optimized: Fast loading, clear CTA, mobile-friendly.
- Negative keyword list ready: Do not waste budget on unnecessary clicks on the first day.
- Realistic budget: Start with €500-€1,500/month in the testing phase. Too small a budget (under €300/month) does not produce data or results.
- Precise goals: Define in advance what an acceptable CPA and target ROAS are. Do not just ‘try it’; measure results against goals.
Campaign structure: Divide campaigns into clear themes. Do not put all keywords into one campaign. Example of a good structure:
- Campaign 1: Brand searches (for example ‘Company Ltd’) - protect your brand from competitors, lowest CPC
- Campaign 2: High-intent keywords (for example ‘order [service]’) - highest budget, best ROAS
- Campaign 3: Research-stage searches (for example ‘what is the best [product]’) - lower budget, longer sales cycle
6. Remarketing - reach users who did not convert
95% of visitors do not convert on the first visit. This is normal; a purchase decision takes time. With remarketing, you can stay top of mind and bring them back.
Google Display Remarketing: Show banners to users who have visited your site. These ads follow them around the web (YouTube, news sites, blogs). The CPA of remarketing campaigns is often 50-70% lower than cold campaigns.
Google Search Remarketing (RLSA): Raise bids for keywords when the user has already visited your site. Example: If someone has viewed your product page and later searches ‘best price [product]’, show them a more aggressive ad in a higher position.
In summary: Google Ads offers a fast and effective way to reach customers considering a purchase. When a campaign is built correctly and optimized continuously, it can be your company’s most important lead machine. Focus on high-intent keywords, optimize Quality Score to lower costs, use precise targeting (location, time, device), measure results continuously, and use remarketing. This is how you reach buyers at the right moment and turn them into customers. Interested in starting Google Ads? Also explore Google Ads pricing and the Google Ads buying guide.
