The Challenge: Generic Campaign Targeting

Most marketing teams still target in broad strokes: large demographics, basic interests, and one-size-fits-all messaging. On paper, reach looks impressive. In reality, generic campaign targeting means you pay to show ads to people who will never become customers. You collect clicks and impressions instead of qualified leads and revenue.

Traditional approaches leaned on media buying intuition, static personas, and backward-looking reports. That might have worked when competition and media costs were lower. Today, algorithms trade in real-time signals and micro-intents, while many teams are still planning campaigns quarterly and adjusting them manually. Spreadsheets, rough segment definitions, and a few A/B tests can’t keep up with the speed and granularity required in modern performance marketing.

The business impact is clear: rising cost per lead, inconsistent lead quality, and campaigns that become impossible to scale profitably. Budget gets locked into underperforming segments because no one has the data or capacity to see which audiences are truly high-propensity. Sales teams lose trust in marketing leads, and marketing struggles to prove ROI, even when top-line traffic is growing.

This challenge is real, but it’s solvable. With the right use of AI-driven audience intelligence, you can move from broad, generic targeting to precise, intent-based segments that continuously learn and improve. At Reruption, we’ve seen how embedding AI into real workflows — not just dashboards — changes how teams run acquisition. In the sections below, you’ll find practical, step-by-step guidance on using Gemini with your Google Ads and Analytics data to turn generic campaigns into focused lead engines.

Our Assessment

A strategic assessment of the challenge and high-level tips how to tackle it.

From Reruption’s implementation work, we’ve learned that the real unlock with Gemini for campaign targeting is not just better suggestions, but a different operating model for how marketing teams use data. When you connect Gemini to Google Ads and Google Analytics, it becomes a continuous strategist: surfacing high-intent segments, suggesting creative angles, and highlighting waste you can cut without hurting lead volume.

Think in Propensity, Not Just Personas

Most teams define audiences as personas: “IT decision makers in mid-sized companies”, or “parents aged 30–45”. With Gemini-powered targeting, you can shift from static personas to propensity-based segments built on real behavior and outcomes. Instead of asking “Who do we want to reach?”, you ask “Who has recently behaved like our best leads?”

Strategically, this means marketing, sales, and data teams must align on what a “high-intent lead” actually is: channel touchpoints, content consumed, actions taken, speed to respond, and eventual deal outcomes. Gemini then uses this agreed definition to look across your Ads and Analytics data and surface segments that look like these high-performing leads, including combinations that humans would rarely test manually.

Use Gemini as a Co-Strategist, Not Just a Tactic Engine

Many organisations treat AI tools as a place to generate ad copy or headlines. To really solve generic campaign targeting, you want Gemini to sit one level higher: as a co-strategist helping decide where to invest budget and which audiences to prioritise. This changes the questions you ask from “write me 20 headlines” to “show me which search queries or in-market segments signal high purchase intent in the last 30 days”.

At a strategic level, put Gemini into your monthly and quarterly planning rituals. Have the team review Gemini’s recommended audiences, negative keywords, and in-market groups alongside human research. Over time, this builds trust in the system and reduces reliance on gut feel. You’re not replacing human judgment; you’re giving it a far better map.

Prepare Your Data and Tracking Before You Scale AI

Gemini’s recommendations are only as strong as the conversion tracking and event data it sees. If you still optimise for generic form fills, every low-quality download looks like success. Strategically, you need a clean definition of “qualified lead” and “opportunity” reflected in your Analytics events and Ads conversion imports. That’s the foundation for AI-based audience refinement.

Invest time aligning CRM statuses, lead scoring rules, and Analytics events so that Gemini can distinguish between noise and signal. This might require marketing ops and sales ops collaboration, but it’s the difference between AI that optimises for vanity metrics and AI that genuinely increases pipeline.

Start with Focused Pilots, Not Full-Funnel Overhauls

A common mistake is trying to make Gemini “fix everything” at once: all campaigns, all geos, all products. A more resilient strategy is to choose one high-value lead gen funnel (for example, a core B2B service or flagship product) and run a controlled pilot. Limit variables so you can clearly see what Gemini-driven targeting changes versus your status quo.

In this pilot, set explicit hypotheses: which segments should improve, what lift in conversion rate you expect, what cost-per-lead threshold you won’t exceed. This makes the experiment measurable and helps secure stakeholder buy-in when you later scale Gemini-based workflows to other campaigns.

Manage Risk with Guardrails and Human Review

Handing over segmentation decisions to an AI model without guardrails is risky. Strategically, you need clear boundaries: budgets per experiment, excluded audiences, and brand or regulatory constraints. Gemini is powerful at detecting patterns in high-intent behavior, but it doesn’t understand your risk appetite unless you encode it into rules and review processes.

Set up a cadence where marketers review Gemini’s new audience and creative suggestions weekly, approve or adjust them, and monitor lead quality with sales feedback. This human-in-the-loop approach protects brand equity and ensures that AI-driven optimisations are aligned with your real-world commercial goals.

Used thoughtfully, Gemini can turn generic campaign targeting into a data-driven, intent-based lead engine, but only if it’s grounded in clean signals, clear definitions of “qualified”, and a deliberate pilot strategy. At Reruption, we specialise in embedding this kind of AI-first workflow into existing marketing setups, so your team gains precision without adding complexity. If you’re ready to see what Gemini can do with your Google Ads and Analytics data, we can help you test it safely, prove its impact, and scale what works.

Real-World Case Studies

From Healthcare to Fintech: Learn how companies successfully use Gemini.

NYU Langone Health

Healthcare

NYU Langone Health, a leading academic medical center, faced significant hurdles in leveraging the vast amounts of unstructured clinical notes generated daily across its network. Traditional clinical predictive models relied heavily on structured data like lab results and vitals, but these required complex ETL processes that were time-consuming and limited in scope. Unstructured notes, rich with nuanced physician insights, were underutilized due to challenges in natural language processing, hindering accurate predictions of critical outcomes such as in-hospital mortality, length of stay (LOS), readmissions, and operational events like insurance denials. Clinicians needed real-time, scalable tools to identify at-risk patients early, but existing models struggled with the volume and variability of EHR data—over 4 million notes spanning a decade. This gap led to reactive care, increased costs, and suboptimal patient outcomes, prompting the need for an innovative approach to transform raw text into actionable foresight.

Lösung

To address these challenges, NYU Langone's Division of Applied AI Technologies at the Center for Healthcare Innovation and Delivery Science developed NYUTron, a proprietary large language model (LLM) specifically trained on internal clinical notes. Unlike off-the-shelf models, NYUTron was fine-tuned on unstructured EHR text from millions of encounters, enabling it to serve as an all-purpose prediction engine for diverse tasks. The solution involved pre-training a 13-billion-parameter LLM on over 10 years of de-identified notes (approximately 4.8 million inpatient notes), followed by task-specific fine-tuning. This allowed seamless integration into clinical workflows, automating risk flagging directly from physician documentation without manual data structuring. Collaborative efforts, including AI 'Prompt-a-Thons,' accelerated adoption by engaging clinicians in model refinement.

Ergebnisse

  • AUROC: 0.961 for 48-hour mortality prediction (vs. 0.938 benchmark)
  • 92% accuracy in identifying high-risk patients from notes
  • LOS prediction AUROC: 0.891 (5.6% improvement over prior models)
  • Readmission prediction: AUROC 0.812, outperforming clinicians in some tasks
  • Operational predictions (e.g., insurance denial): AUROC up to 0.85
  • 24 clinical tasks with superior performance across mortality, LOS, and comorbidities

John Deere

Agriculture

In conventional agriculture, farmers rely on blanket spraying of herbicides across entire fields, leading to significant waste. This approach applies chemicals indiscriminately to crops and weeds alike, resulting in high costs for inputs—herbicides can account for 10-20% of variable farming expenses—and environmental harm through soil contamination, water runoff, and accelerated weed resistance . Globally, weeds cause up to 34% yield losses, but overuse of herbicides exacerbates resistance in over 500 species, threatening food security . For row crops like cotton, corn, and soybeans, distinguishing weeds from crops is particularly challenging due to visual similarities, varying field conditions (light, dust, speed), and the need for real-time decisions at 15 mph spraying speeds. Labor shortages and rising chemical prices in 2025 further pressured farmers, with U.S. herbicide costs exceeding $6B annually . Traditional methods failed to balance efficacy, cost, and sustainability.

Lösung

See & Spray revolutionizes weed control by integrating high-resolution cameras, AI-powered computer vision, and precision nozzles on sprayers. The system captures images every few inches, uses object detection models to identify weeds (over 77 species) versus crops in milliseconds, and activates sprays only on targets—reducing blanket application . John Deere acquired Blue River Technology in 2017 to accelerate development, training models on millions of annotated images for robust performance across conditions. Available in Premium (high-density) and Select (affordable retrofit) versions, it integrates with existing John Deere equipment via edge computing for real-time inference without cloud dependency . This robotic precision minimizes drift and overlap, aligning with sustainability goals.

Ergebnisse

  • 5 million acres treated in 2025
  • 31 million gallons of herbicide mix saved
  • Nearly 50% reduction in non-residual herbicide use
  • 77+ weed species detected accurately
  • Up to 90% less chemical in clean crop areas
  • ROI within 1-2 seasons for adopters

Rolls-Royce Holdings

Aerospace

Jet engines are highly complex, operating under extreme conditions with millions of components subject to wear. Airlines faced unexpected failures leading to costly groundings, with unplanned maintenance causing millions in daily losses per aircraft. Traditional scheduled maintenance was inefficient, often resulting in over-maintenance or missed issues, exacerbating downtime and fuel inefficiency. Rolls-Royce needed to predict failures proactively amid vast data from thousands of engines in flight. Challenges included integrating real-time IoT sensor data (hundreds per engine), handling terabytes of telemetry, and ensuring accuracy in predictions to avoid false alarms that could disrupt operations. The aerospace industry's stringent safety regulations added pressure to deliver reliable AI without compromising performance.

Lösung

Rolls-Royce developed the IntelligentEngine platform, combining digital twins—virtual replicas of physical engines—with machine learning models. Sensors stream live data to cloud-based systems, where ML algorithms analyze patterns to predict wear, anomalies, and optimal maintenance windows. Digital twins enable simulation of engine behavior pre- and post-flight, optimizing designs and schedules. Partnerships with Microsoft Azure IoT and Siemens enhanced data processing and VR modeling, scaling AI across Trent series engines like Trent 7000 and 1000. Ethical AI frameworks ensure data security and bias-free predictions.

Klarna

Fintech

Klarna, a leading fintech BNPL provider, faced enormous pressure from millions of customer service inquiries across multiple languages for its 150 million users worldwide. Queries spanned complex fintech issues like refunds, returns, order tracking, and payments, requiring high accuracy, regulatory compliance, and 24/7 availability. Traditional human agents couldn't scale efficiently, leading to long wait times averaging 11 minutes per resolution and rising costs. Additionally, providing personalized shopping advice at scale was challenging, as customers expected conversational, context-aware guidance across retail partners. Multilingual support was critical in markets like US, Europe, and beyond, but hiring multilingual agents was costly and slow. This bottleneck hindered growth and customer satisfaction in a competitive BNPL sector.

Lösung

Klarna partnered with OpenAI to deploy a generative AI chatbot powered by GPT-4, customized as a multilingual customer service assistant. The bot handles refunds, returns, order issues, and acts as a conversational shopping advisor, integrated seamlessly into Klarna's app and website. Key innovations included fine-tuning on Klarna's data, retrieval-augmented generation (RAG) for real-time policy access, and safeguards for fintech compliance. It supports dozens of languages, escalating complex cases to humans while learning from interactions. This AI-native approach enabled rapid scaling without proportional headcount growth.

NatWest

Banking

NatWest Group, a leading UK bank serving over 19 million customers, grappled with escalating demands for digital customer service. Traditional systems like the original Cora chatbot handled routine queries effectively but struggled with complex, nuanced interactions, often escalating 80-90% of cases to human agents. This led to delays, higher operational costs, and risks to customer satisfaction amid rising expectations for instant, personalized support . Simultaneously, the surge in financial fraud posed a critical threat, requiring seamless fraud reporting and detection within chat interfaces without compromising security or user trust. Regulatory compliance, data privacy under UK GDPR, and ethical AI deployment added layers of complexity, as the bank aimed to scale support while minimizing errors in high-stakes banking scenarios . Balancing innovation with reliability was paramount; poor AI performance could erode trust in a sector where customer satisfaction directly impacts retention and revenue .

Lösung

Cora+, launched in June 2024, marked NatWest's first major upgrade using generative AI to enable proactive, intuitive responses for complex queries, reducing escalations and enhancing self-service . This built on Cora's established platform, which already managed millions of interactions monthly. In a pioneering move, NatWest partnered with OpenAI in March 2025—becoming the first UK-headquartered bank to do so—integrating LLMs into both customer-facing Cora and internal tool Ask Archie. This allowed natural language processing for fraud reports, personalized advice, and process simplification while embedding safeguards for compliance and bias mitigation . The approach emphasized ethical AI, with rigorous testing, human oversight, and continuous monitoring to ensure safe, accurate interactions in fraud detection and service delivery .

Ergebnisse

  • 150% increase in Cora customer satisfaction scores (2024)
  • Proactive resolution of complex queries without human intervention
  • First UK bank OpenAI partnership, accelerating AI adoption
  • Enhanced fraud detection via real-time chat analysis
  • Millions of monthly interactions handled autonomously

Best Practices

Successful implementations follow proven patterns. Have a look at our tactical advice to get started.

Connect Gemini to Clean, Lead-Centric Conversion Signals

Before asking Gemini for smarter segments, fix what it learns from. Replace generic “all form fills” conversions with granular events that reflect lead quality, such as MQLs, SQLs, or demo bookings imported from your CRM. In Google Analytics, configure events and conversions that distinguish between: newsletter signups, content downloads, demo requests, and opportunity-creating actions.

Once these are correctly mapped, connect Gemini to the corresponding Google Ads accounts and Analytics properties. The goal is simple: when you later ask Gemini “Which audiences drive high-intent leads?”, it sees the difference between noise (e.g., ebook hoarders) and actual pipeline contributors.

Use Gemini to Mine Analytics for High-Intent Audience Patterns

Instead of manually sifting through dozens of reports, have Gemini analyse your Analytics user and session data for patterns tied to high-quality leads. Provide it with exports of key reports (by campaign, channel, in-market segment, and device) and ask it to surface combinations that correlate with strong lead indicators.

Example Gemini prompt for audience discovery:

You are a performance marketing analyst.

You get a CSV export from Google Analytics and Google Ads with:
- Campaign, ad group, keyword/audience
- In-market and affinity segments
- Device, geo, time of day
- Conversions for: MQL, SQL, Opp Created
- Cost and clicks

1) Identify audience and query patterns that have:
   - High SQL rate and Opp Created rate
   - Stable volume over the last 30 days
2) Flag any segments with high spend but low SQL/Opp rates.
3) Propose 5-10 high-propensity audience definitions we should test
   (e.g., in-market + device + geo/remarketing conditions).
4) Output structured recommendations with expected impact on CPL.

The output becomes a prioritised testing backlog: which in-market segments to add, which audiences to exclude, and where to shift budget for better lead quality.

Generate and Localise Creative Variations for Each High-Intent Segment

Once you’ve identified promising segments, use Gemini to generate segment-specific messaging and assets instead of one generic ad set. Feed it the segment description, your value proposition, and examples of high-performing creatives. Ask Gemini to tailor headlines, descriptions, and landing page hooks to the pain points and intent level of each segment.

Example Gemini prompt for segment-specific creative:

You are a B2B marketing copywriter.

Context:
- Product: <short description>
- Target segment: Google Ads in-market audiences X, Y, Z
- Pain points: <list from sales calls>
- Desired action: Request a demo (high-intent)

Tasks:
1) Write 10 Google Ads headlines (max 30 chars) that speak directly
   to this segment's pain points and intent.
2) Write 5 descriptions (max 90 chars) emphasising speed, risk
   reduction, and clear ROI.
3) Suggest 3 angles for the hero section on the landing page to
   match this segment (headline + subhead + CTA).

Implement these variations in Google Ads and on your landing pages, mapping each ad group to the relevant creative to ensure that high-intent audiences see messaging that actually fits their context.

Automate an Always-On Targeting Review Routine with Gemini

Generic targeting tends to creep back in over time as campaigns evolve. Set up an always-on review workflow where Gemini regularly analyses performance data and flags segments that are drifting or wasting spend. Export weekly Ads and Analytics performance screenshots or CSVs, and run a templated analysis prompt.

Example Gemini prompt for weekly targeting review:

You are monitoring lead generation performance.

Input: Last 7 and 30 days of Google Ads + Analytics data by
- Campaign, ad group, audience, keyword
- Conversions split by MQL, SQL, Opp
- Cost, CPC, CPL, ROAS

1) Highlight audiences/keywords where CPL for SQL has worsened by
   >20% vs the previous period.
2) Identify any new audience/keyword combos with promising SQL rates
   but low spend (scaling opportunities).
3) Recommend concrete actions for next week:
   - Budgets to cut or increase
   - Audiences to pause, refine, or expand
   - Additional negative keywords or placements.

Turn the output into a lightweight weekly optimisation checklist. This keeps campaigns sharp without demanding hours of manual analysis from your team.

Use Gemini to Align Marketing and Sales on Lead Quality Definitions

One root cause of poor targeting is a disconnect between marketing metrics and what sales calls a “good lead”. Use Gemini as a neutral facilitator: feed it anonymised CRM notes, call summaries, and lead statuses to extract patterns of high-intent behavior that sales actually values.

Example Gemini prompt for lead quality analysis:

You are analysing lead quality.

Input: Anonymised CRM exports with:
- Lead source, campaign, keyword
- Activity timeline (pages visited, content consumed)
- Sales notes and outcome (Won/Lost, reasons)

Tasks:
1) Identify behaviour patterns common to Won deals vs Lost.
2) Translate these patterns into concrete targeting and scoring
   rules for marketing (e.g., pages visited, time-on-site,
   sequence of touches).
3) Propose a refined "qualified lead" definition that marketing
   can optimise campaigns against.

Implement the refined definitions in your Analytics events and Ads conversions. This ensures Gemini’s targeting suggestions are grounded in what actually produces revenue, not just form fills.

Build a Gemini-Assisted Lead Nurturing Layer for Non-Ready Prospects

Not every click from a high-intent audience will convert immediately. Rather than discarding them as “bad leads”, use Gemini to design nurture sequences (email, remarketing, or chatbots) that keep potential buyers engaged until they’re ready. Segment these contacts based on interest and behavior and ask Gemini to propose educational and problem-focused content journeys.

Example Gemini prompt for nurture design:

You are designing a lead nurture sequence.

Context:
- Segment: Visitors who engaged with pricing and case studies but
  did not request a demo.
- Goal: Convert them to demo within 30 days.

Tasks:
1) Propose a 4-touch email sequence (subject + body outline) that
   addresses typical objections and reinforces value.
2) Suggest 3 remarketing ad angles to support this sequence.
3) Define 3 key events we should track to qualify a nurtured lead
   as "ready for sales".

Implement these nurture flows in your marketing automation tools and align tracking so that when nurtured leads hit defined thresholds, they are upgraded in your CRM and reflected back into Ads/Analytics conversions.

When teams consistently apply these practices, it’s realistic to see 20–40% reductions in cost per qualified lead, more stable lead quality for sales, and greater confidence in scaling spend behind the best-performing segments. The exact uplift depends on your starting point, but the direction is clear: Gemini helps you remove waste, focus on high-propensity audiences, and turn generic campaigns into predictable lead generation engines.

Frequently Asked Questions

Gemini reduces generic campaign targeting by analysing your existing Google Ads and Analytics data to find patterns tied to high-quality leads, not just clicks. It can highlight which in-market segments, search queries, and audience combinations are consistently associated with MQLs, SQLs, or opportunities, and which are just burning budget.

Practically, you feed Gemini exported reports (or connect it via workflows), ask it to identify high-propensity segments and underperforming audiences, and then implement its recommendations in Ads: adding new audiences, refining existing ones, adjusting bids, and excluding low-intent traffic. Over time, this moves your targeting from broad demographics to behaviour-driven, intent-based segments.

You don’t need a full data science team, but you do need three capabilities: a marketer who understands your funnels and KPIs, someone comfortable with Google Ads/Analytics configuration, and a person who can work with Gemini prompts and workflows (often the same marketer after light enablement).

The key is having clean conversion tracking and basic data exports from Ads and Analytics. From there, Gemini can handle analysis and recommendations. Reruption typically helps clients set up the initial data flows, design prompt templates, and train the marketing team to run these analyses as part of their normal optimisation routine.

In most setups, you can see early directional results within 2–4 weeks and more robust improvements within 6–12 weeks. The first weeks are about cleaning up tracking, running initial Gemini analyses, and launching a few high-impact tests on audience segments and messaging.

Once those tests have enough data, you can typically start cutting wasted spend on low-propensity audiences and shifting budget to better-performing segments. The timeline depends on your traffic volume and sales cycle, but for many B2B and B2C lead gen campaigns, meaningful improvements in cost per qualified lead become visible within a quarter.

Using Gemini for campaign targeting is less about spending more and more about spending smarter. In many cases, the first phase actually lowers spend by cutting clearly underperforming segments and keywords. You then reinvest those savings into the high-intent audiences Gemini identifies.

ROI improvements usually come from 20–40% reductions in cost per qualified lead and better lead-to-opportunity conversion rates, not from massive budget hikes. The main investment is time for setup and ongoing review. When implemented correctly, Gemini pays for itself by eliminating budget leakage and enabling you to scale only what actually generates revenue.

Reruption helps marketing teams move from theory to a working Gemini-powered lead generation setup. With our 9.900€ AI PoC, we validate a concrete use case such as “reduce cost per SQL by 30% using Gemini audience optimisation” and build a functioning prototype: data flows from Google Ads/Analytics, Gemini analysis prompts, and a pilot campaign with new segments and creatives.

Beyond the PoC, our Co-Preneur approach means we embed with your team, work inside your P&L, and take ownership for actually changing how campaigns are run — not just delivering slides. We support you on AI strategy, technical configuration, prompt design, and enablement so that your marketers can confidently use Gemini every week to keep targeting sharp and lead quality high.
