PPC and Performance Max Agency London: Google Ads Measured Against Pipeline
A PPC and Performance Max agency in London should judge Google Ads by qualified pipeline, not clicks. Integrated.Social fixes conversion tracking first, then shapes search, Shopping and Performance Max around the buyer persona that drives your organic content, so paid and earned messages agree. A senior specialist reviews every change; no return on spend is promised.
We audit and rebuild Google Ads with persona-driven targeting, structured A/B testing and conversion-tracking discipline. We report the available evidence against the commercial question, rather than promising a return on spend. For dedicated PMax control, see our Performance Max agency.

Method
How we run your account
The first fortnight is measurement: we check every conversion fires once and maps to a pipeline stage. Then we rebuild campaigns around the buyer persona your SEO and content already use, so the search ad, the landing page and the organic answer say the same thing. Bids change last.
Fit
Who this is for, and who it is not for
For: London B2B advertisers with tracked conversions who want Google Ads judged on pipeline.
Not for: accounts without conversion tracking they are willing to fix, or buyers who want guaranteed ROAS.

What we manage
Every lever that affects your paid acquisition cost and quality.
Google Search Ads
High-intent keyword targeting, negative keyword hygiene, ad copy testing, and bid strategy optimization. We build and validate keyword structures, match types, and negative lists before upload to Google Ads Editor. We focus on search terms that indicate buying intent, not just traffic volume.
Performance Max
Strategic asset group structure, audience signals, feed quality for Shopping, and creative testing. We maintain control levers that most agencies ignore, because PMax without discipline wastes budget.
Conversion Tracking
GA4 setup, offline conversion imports, enhanced conversions, and attribution modeling. Clean data is the foundation, if your tracking is wrong, every optimization decision is wrong.
Structured A/B Testing
Systematic experiments across ads, audiences, bids, and landing pages. Each test has a hypothesis, minimum sample size, and clear success criteria. No random changes, no gut feelings.
Budget & Bid Strategy
Smart budget allocation across campaigns, dayparting, device adjustments, and bidding strategy selection. We match your budget to the highest-value opportunities first.
Reporting & Insights
Weekly performance reports with actionable insights. Not dashboards full of vanity metrics. We report on pipeline contribution, CPA by segment, and incremental revenue from PPC.
The art & science of PPC
The Art, Understanding Your Buyer
- Persona mapping: who buys, what triggers them, how they search
- Message-market fit: ads that speak to pain points, not features
- Landing page narrative: guiding the buyer from click to conversion
- Brand consistency: paid messaging that reinforces organic positioning
- Competitive differentiation: standing out in a crowded SERP
The Science, Measurable Improvement
- Statistical significance: no declaring winners on 50 clicks
- Multi-variate testing: isolating variables that actually move CPA
- Attribution modeling: understanding the real path to conversion
- Incrementality testing: proving PPC adds value beyond organic
- Automated bid adjustments: letting data drive spend allocation
Evidence before optimisation
We begin with the tracking and journey evidence that is available, then make a documented decision about the next test. Results depend on the account, offer, budget and market. No ROAS or CPA result is promised.

ChatGPT Ads launched in the UK in June 2026 with self-serve access, no minimum spend, and CPC bids from $3. The audience targeting layer is not live yet, which means early movers are competing on content quality and landing page relevance, not audience precision.

What should PPC and Performance Max be measured against?
Integrated.Social measures PPC and Performance Max in order: tracked conversions, then qualified leads, then pipeline, then revenue where your data allows. We report Performance Max separately from brand search, so demand you already had is not counted as new. Platform-reported ROAS is a useful signal, but it is not the business result. Pipeline is the measure we review with you.

Rising spend with flat lead quality can indicate a targeting or conversion-tracking problem. The account may be optimising for the wrong signal, or its structure may be too broad for the buyer intent. We audit conversion tracking first, then use the evidence available to decide whether campaigns and landing pages need to change. Results depend on the starting account, offer and market.
The most common reasons B2B Google Ads fail: tracking clicks instead of qualified pipeline, using broad match keywords that attract irrelevant traffic, sending paid traffic to a generic homepage instead of a conversion-optimized landing page, and not having enough budget to generate statistical significance. We address all four before spending a pound on media. If your market is too competitive for your budget, we will tell you honestly rather than take your money.
ROAS is a starting metric, not the only one. We track: cost per qualified lead (not just any lead), pipeline contribution (how much revenue entered the funnel from PPC), customer acquisition cost by segment, incrementality (what PPC adds beyond organic), and lifetime value of PPC-acquired customers. Every metric ties back to pipeline and revenue, not impressions or clicks.
Treat any emerging ad channel as a test, not a forecast. First confirm what inventory, targeting, measurement and policy controls are available, then decide whether the buyer, offer and tracking support a bounded trial. Paid-search evidence can also help identify useful questions for your SEO and AEO work, without assuming an answer-engine mention or CPC outcome.
PPC and SEO/AEO can use the same buyer-question and landing-page evidence. Search-term reports can inform content priorities, while clear organic pages can give paid visitors a more consistent journey. We report each channel separately and do not assume that an answer-engine mention causes a paid-media outcome.
AI can support research, analysis and draft variants, but it does not remove the need for accountable PPC management. At Integrated.Social, a senior person reviews conversion signals, audience choices, claims and spend before material changes go live. The useful distinction is a documented testing process with human review, not an autonomous promise.
Google AI features can change how a search-results page is presented. Review the real search-result layout, query intent and available performance data before changing campaigns. PPC, SEO and AEO should share clear buyer questions and landing-page evidence, but Google decides what appears in an AI feature and no citation or traffic effect is guaranteed.
B2B PPC with long sales cycles requires a different attribution model than B2C. We build multi-touch attribution that tracks the full journey from first paid click through content engagement, demo request, sales qualification, and closed deal. We segment campaigns by buying stage: awareness campaigns targeting in-market accounts with educational content, consideration campaigns retargeting engaged visitors with case studies and proof points, and decision campaigns targeting high-intent queries with direct conversion offers. Budget allocation shifts based on pipeline velocity data from your CRM, not just click-through rates.
Yes, and the integration is where the leverage is. Google Ads captures intent at the moment of search; LinkedIn Ads builds awareness and authority with your target accounts before they search. We run coordinated campaigns where LinkedIn account-based targeting seeds awareness with your ICP, and Google Ads captures the resulting search intent with tailored messaging. Retargeting lists from LinkedIn are used as audience signals in Google PMax, and search term data from Google informs LinkedIn content strategy. The result is a consistent brand presence across the full buyer journey.
The minimum viable B2B PPC budget depends on your average deal value and sales cycle length. As a general rule, you need enough budget to generate statistically significant conversion data within 60-90 days. For most B2B SaaS and professional services companies in the UK, this means a minimum of £3,000-£5,000 per month in ad spend to generate enough data to optimize effectively. Below that threshold, campaigns do not accumulate enough conversion signals for Google's algorithms to optimize, and you end up paying learning-phase CPCs indefinitely. We assess your specific market and deal economics before recommending a starting budget.
International PPC requires separate campaign structures per market, not just geo-targeting overlays on a single campaign. Search behavior, competitive density, and CPCs vary significantly between the UK, US, DACH, and APAC markets. We build market-specific campaigns with localised ad copy, landing pages, and bidding strategies. For Performance Max, we use separate asset groups per market to prevent Google's algorithm from averaging performance across markets with very different conversion rates. We also integrate market-specific AEO content strategies so your brand builds citation authority in each target market's AI search ecosystem.

What is Performance Max and how does AI optimise it?
Performance Max (PMax) is Google's AI-driven campaign type that serves ads across Search, Shopping, Display, YouTube, Gmail, and Maps from a single campaign. Google's machine learning allocates budget to the highest-converting placements automatically. Without specialist management, PMax tends to over-invest in brand terms, under-invest in prospecting, and produce opaque performance data. We manage PMax with structured asset groups per buyer persona, negative keyword lists that prevent brand cannibalisation, custom audience signals from your CRM, and weekly reviews that feed back into asset strategy.
How does PPC work alongside AEO and AI search?
PPC and AEO are more powerful together than either is alone. As Google AI Mode reduces organic CTR by 20–35% on commercial queries (SISTRIX data, cited at Google I/O 2026), PPC becomes the reliable traffic floor while AEO builds the citation authority that reduces long-term CPCs. We use PPC search term data to validate AEO content opportunities, align landing pages across paid and organic, and coordinate messaging so paid and AI-generated answers reinforce each other. Brands that build AEO citation authority now will have a structural cost advantage when ChatGPT advertising scales.
What ROAS can we expect from AI-optimised PPC?
ROAS targets depend on your sector, average deal size, and current account health. Most B2B clients see cost-per-qualified-lead drop 20–40% within 60 days of restructuring conversion tracking and campaign architecture (indicative range from Integrated.Social client engagements; individual results vary). We track pipeline contribution (revenue entering the funnel from PPC), customer acquisition cost by segment, and incrementality (what PPC adds beyond organic) rather than relying on ROAS alone. Every metric ties back to pipeline and closed revenue, not impressions or clicks.
How do you handle PPC for regulated industries?
Regulated industries such as FinTech, financial services, legal, and healthcare require additional compliance layers in PPC management. We build pre-flight compliance checks into every ad copy and landing page review cycle, maintain sector-specific negative keyword lists that prevent ad serving on prohibited terms, and structure campaigns to meet Google's financial products and services advertising policies. We have managed PPC for regulated B2B clients where every asset must pass legal review before going live, and we build that review cycle into our workflow from day one.
