Optimising Google Ads Structures to Improve B2B Lead Quality

Unlocking the True Potential of Google Ads for B2B Lead Generation

Many B2B companies investing in Google Ads find themselves caught in a cycle of rising costs and underwhelming results. Budgets drain away on clicks that don’t convert, while the challenge of generating quality leads intensifies. But what if we told you that some businesses consistently achieve scalable, high-quality pipeline growth? The secret lies not in throwing more money at campaigns but in how they are structured, targeted, and optimised.

Drawing from extensive experience managing B2B paid media campaigns, we’ve uncovered what sets the top performers apart. The difference? Rigorous account organisation, laser-focused keyword strategies, and data-led optimisation that drives real business impact.

Why Account Structure is the Backbone of Success

The architecture of your Google Ads account can make an enormous difference to performance. Without clear segmentation and intent-driven structuring, campaigns become cluttered with unrelated keywords, confusing signals to Google’s machine learning, and ultimately wasting your ad spend.

Best-in-class B2B accounts align each campaign with specific business goals or product lines. This means:

Dedicated campaigns for distinct services instead of mixing unrelated offerings.
Ad groups focused around tightly themed keyword clusters, commonly known as Single Theme Ad Groups (STAGs), containing 5 to 15 closely related terms.
Clear messaging and tailored landing pages aligned with each ad group’s intent.

This granular approach boosts your Quality Score, improves conversion rates, and lowers cost per lead by ensuring budget flows to the most productive areas.

For example, we’ve seen accounts with more than 200 scattered keywords reduce cost per lead by nearly 50% simply by reorganising campaigns and ad groups around distinct services—without increasing spend.

Mastering Keyword Strategy for Better Lead Quality

Many B2B advertisers fall into the trap of chasing high-volume keywords without considering the true intent behind a search. Top-tier accounts turn that upside down by rigorously prioritising:

Commercial intent over general research—targeting terms signaling active buying decisions rather than early-stage inquiries.
Long-tail keywords that specify niches or user needs, such as “CRM for manufacturing” rather than broad terms like “CRM software.” These are often less expensive and yield higher conversion rates.
Extensive use of negative keywords to block irrelevant traffic. Sophisticated B2B accounts maintain lists of hundreds of negatives including “free”, “jobs”, “courses”, and competitor names (unless explicitly targeting competitors).
Regularly auditing search terms weekly or biweekly, swiftly removing wasteful queries that consume budget with no return.
Prudent management of broad match keywords, often defaulted by Google. While valuable for discovery, high performers mainly use broad match for branded or proven terms, preferring phrase match elsewhere for tighter control.

Pinpoint Targeting: Getting Your Ads in Front of the Right Decision Makers

Beyond keywords, leveraging Google Ads’ advanced targeting options is critical to reduce wasted spend and increase lead relevance:

Audience targeting: Uploading your CRM customer lists enables “customer match” and lookalike audiences, refining ad delivery to users resembling your best clients.
Geographic bid adjustments: Bidding higher in key regions and reducing or excluding low-value locations improves cost efficiency.
Device bidding strategies: While mobile browsing now accounts for a majority of B2B research, conversion rates tend to be higher on desktop. Smart campaigns bid less aggressively on mobile without excluding it entirely.
Remarketing lists for search ads (RLSA): Dedicated campaigns for visitors who didn’t convert initially, with more assertive messaging and bids tuned for warmer audiences.
Cross-channel coordination: Combining LinkedIn Ads with Google allows simultaneous search demand capture and brand awareness among decision-makers, dramatically improving overall impact.

Conversion Tracking: The Cornerstone of Meaningful Optimisation

Without accurate measurement, you can never truly understand the effectiveness of your campaigns. Unfortunately, many B2B Google Ads accounts fall short in this area.

Leading organisations set up comprehensive tracking that goes far beyond counting form fills. This includes:

Demo requests, phone calls, chat engagements, content downloads, and video views.
Assigning weighted values to different conversion types based on average deal size and sales velocity.
Offline conversion tracking linking CRM closed deals back to ad interactions, allowing Google’s smart bidding to optimise for actual revenue outcomes instead of preliminary leads.

For many B2B clients, starting with the “Maximise Conversions” bidding strategy, with a target CPA constraint, creates the right balance between automation and control during account growth.

Data-Driven Budget Allocation: The Secret to Maximising ROI

High-performing Google Ads accounts strictly follow the data. Here’s what defines their budget strategy:

Prioritising branded search campaigns — Dreamdata's 2024 research highlights a staggering 1299% ROAS on branded terms, contrasted with only 78% on non-branded ones. Yet many advertisers underinvest in branded campaigns despite their superior efficiency.
Investing wisely in non-branded campaigns, which form the growth engine but require constant optimisation to meet acceptable cost per lead benchmarks (averaging around £140 in 2024 according to Firebrand).
Separating campaign budgets to prevent weaker campaigns from starving the better performers, which is common when using shared budgets indiscriminately.

Cultivating a Culture of Continuous Testing

In the dynamic landscape of B2B advertising, resting on laurels isn’t an option. High performers embed systematic testing into every part of their account:

Ad copy experiments focusing on one variable at a time to reliably identify winning messages.
Responsive Search Ads (RSAs) featuring genuinely distinct headlines highlighting benefits, social proof, urgency, and strong calls-to-action.
Respecting statistical significance and patience in lower traffic B2B environments ensures optimisations are based on reliable data.
Landing page A/B testing often yields the largest conversion gains, with simple changes like reducing form fields or repositioning testimonials boosting performance by 20–30% or more.

Reporting That Speaks to Business Goals

Top agencies and in-house teams don’t just report clicks and impressions. They connect every ad metric back to company priorities:

Tracking pipeline contribution, customer acquisition costs, and quality over purely volume-based KPIs.
Monitoring how Google Ads interacts with other channels through integrated dashboards crafted by expert data teams, such as our own Analytics and Reporting solutions.
Evaluating lead quality by analysing MQL-to-SQL conversion rates, deal sizes, sales cycles, and time to close, revealing true ROI.

Watch Out for Common Pitfalls

Jumping into automation too early: Smart bidding requires solid conversion tracking and volume; premature adoption leads to wasted spend.
Neglecting search term reviews: Ignoring ongoing keyword refinement results in continued budget bleed.
Driving traffic to generic pages: Sending ads to homepages or broad solution pages dilutes intent and reduces conversions.
Failing to exclude current customers: Without negative audience targeting, your ads might annoy existing users and waste budget on acquisition efforts.
