Introduction
Google Ads is amongst the most widely used marketing tools in the world, yet it often happens that companies launch campaigns without clear planning and strategy. The result is that whilst the advertising runs, it doesn't deliver the expected results. One of the reasons is that Google Ads isn't positioned within the context of a broader marketing strategy — specifically the marketing funnel, which helps guide the customer from first contact through to actual conversion.
In this article, we'll look at how Google Ads functions within a funnel strategy, what types of campaigns to use in different phases, and how to measure their performance so they deliver genuine results.
- Why connect Google Ads with funnel strategy
Google Ads is a powerful tool, but without understanding the customer journey, its potential can be overlooked. The marketing funnel divides this journey into phases — from first contact through to conversion and later loyalty. When we know where the customer is positioned, we can show them the right advert at the right time.
Strategically connecting Google Ads with the funnel means you'll stop merely "switching on adverts" and instead create campaigns with clear purpose and measurable results.
- Types of campaigns in Google Ads and their role in the funnel
🔹 Search campaigns (Search Network)
Search campaigns are displayed to users who are actively searching for specific terms. This method is typically used in later phases of the funnel — when a potential customer has clearer intent to act.
When to use:
when considering a purchase,
when searching for solutions,
for conversion-oriented campaigns.
🔹 Display campaigns (Content Network)
Display campaigns show visual adverts on various websites that your potential customers visit. They're effective primarily in the top part of the funnel — when building awareness.
When to use:
when building brand,
when reaching broader relevant audiences.
🔹 Video campaigns (YouTube)
Video adverts are excellent for emotional contact with the brand and building awareness. They allow you to reach audiences with visual and audio content, which increases brand memorability.
When to use:
in Awareness and Interest phases of the funnel,
when building trust and awareness.
🔹 Remarketing campaigns
Remarketing means re-engaging users who have already interacted with your site or advert but haven't yet completed a conversion. Such campaigns tend to be very effective because they work with audiences that have already shown interest.
When to use:
after website visits,
after product views,
when abandoning shopping basket.
- How Google Ads works in individual funnel phases
Awareness
The goal in this phase is to reach as many relevant people as possible and bring them first contact with your brand.
Campaign type: Display, Video Optimisation: focus on reach and impressions Message: focus on value and relevant problem solving, not direct sales
Interest
In this phase, the customer begins taking more active interest in the topic, product or solution.
Campaign type: Remarketing, Custom Intent Optimisation: engage remarketing audiences Message: educate, offer content that answers questions
Consideration
The customer is considering options and comparing offers.
Campaign type: Search, Remarketing Optimisation: optimise for conversions Message: compare advantages, present benefits
Conversion
The goal is for the customer to complete a specific action — for example, purchase or registration.
Campaign type: Search, Remarketing Optimisation: CPA, ROAS Message: clear CTA, simple steps
Retention
After the first conversion, it's not the end — ideally, retain the customer and guide them to repeat purchases or recommendations.
Campaign type: remarketing with up-sells, cross-sells Message: personalised offers
- How to set up Google Ads effectively
Define clear objectives
Without deadlines, objectives and metrics, you can't evaluate performance. It's important to define:
what constitutes conversion (lead / purchase),
required CPA,
expected ROAS
Segment audiences according to behaviour
Segmentation means dividing audiences according to: ✔ interest ✔ website interaction ✔ purchasing behaviour
This way you can target each group with relevant messaging.
Measure and optimise continuously
The key to success is proper measurement:
connecting Google Ads with analytics (e.g. GA4),
tracking conversions,
testing creatives and copy
Continuous optimisation improves results whilst reducing costs.
- Most common mistakes in Google Ads management
❌ Unclear campaign objectives
If you don't know what you expect from a campaign, it's difficult to optimise it.
❌ Insufficient segmentation
Targeting "everyone" leads to budget waste and low efficiency.
❌ Ignoring remarketing
Remarketing is one of the most effective elements of campaigns.
❌ Weak creatives and unclear CTA
Even an excellent offer can fail if you don't present it clearly and persuasively.
- Measuring results and optimisation
Track these metrics: ✔ CPA (cost per acquisition) ✔ CTR (click-through rate) ✔ conversion rate ✔ ROAS (return on advertising spend) ✔ audience quality
Optimisation isn't a one-off activity — it's a continuous process of updates, testing and campaign adjustments.
- Conclusion
Google Ads by itself isn't an "automatic solution" that will solve all marketing problems. It's a sophisticated tool that must be embedded within a broader funnel strategy, circulated with data, messaging and analysis.
When you understand Google Ads as part of the funnel — not as an isolated channel — you can: ✔ target relevant segments ✔ reduce budget waste ✔ increase number of conversions ✔ improve return on investment
