PPC agency: pay-per-click campaigns that generate real customers

A PPC agency is a company specialised in managing pay-per-click advertising campaigns on platforms such as Google Ads, Meta Ads, LinkedIn Ads and Microsoft Ads, optimising every euro invested to generate qualified leads or direct sales with measurable ROAS. 65% of the budget in paid advertising is lost on clicks that don’t convert (WordStream, 2025). Not because PPC doesn’t work. Because most companies manage campaigns without strategy, without real measurement and without a PPC agency that understands that a click is not a customer. If you are looking for a PPC agency in Spain that turns ad spend into a sales pipeline, this guide gives you the criteria to make the right decision.

Google Ads, Meta Ads, LinkedIn Ads, Microsoft Ads. Pay-per-click channels generate immediate results when managed with method. But they also burn budget at record speed when managed with improvisation. The average cost per click on Google Ads Spain has risen 12% year on year (SEMrush, 2025). Every badly invested click costs more than a year ago.

At CRONUTS.DIGITAL we manage PPC campaigns for more than 30 active clients with a clear approach: every euro invested has to come back multiplied. If you are looking for a PPC agency or evaluating whether yours measures up, this guide gives you the real criteria to decide.

# What a PPC agency does and why it is not the same as “running ads”

PPC (Pay Per Click) is a digital advertising model where you pay every time someone clicks on your ad. It sounds simple. It isn’t. A professional PPC agency does not just create ads and switch them on. Its work covers the whole conversion chain:

• Keyword and audience research: identifying the searches and profiles with the highest probability of conversion, not just the highest volume.
• Account structure: organising campaigns, ad groups and keywords so the budget flows towards what converts.
• Ad creation: persuasive copy with conversion-oriented copywriting, extensions, and continuous A/B tests.
• Landing pages: design and optimisation of destination pages that turn clicks into leads or sales.
• Tracking and attribution: implementing conversions, connecting with the CRM and measuring the real return, not just clicks.
• Continuous optimisation: bid adjustment, keyword negativisation, budget reallocation and scaling of what works.

If your current agency only sends you a monthly report with impressions and clicks, you don’t have a PPC agency. You have an ad manager.

# Types of PPC campaign a PPC agency must master

PPC is not just Google Ads. A complete PPC agency must know when and how to activate each type of campaign according to the objective, the budget and the buyer persona.

Google Ads: Search, Shopping, Display, Performance Max

Google Ads is still the PPC channel with the highest purchase intent — according to the Google Economic Impact Report (2025), companies earn an average of $8 in profit for every $1 invested in Google Ads. Search campaigns capture users actively searching for your product or service. Shopping is essential for ecommerce. Display covers branding and remarketing. Performance Max uses Google’s AI to distribute budget across all inventories, but it needs data volume and constant supervision. If you want to go deeper into professional Google Ads management, our guide on a Google advertising agency covers the key criteria.

Meta Ads (Facebook and Instagram Ads)

Ideal for generating demand, not for capturing it. The user is not searching for your product: they discover it while browsing. The most effective formats in 2026: Reels Ads for awareness, native Lead Forms for direct lead capture, and Advantage+ campaigns for ecommerce that leverage Meta’s machine learning.

LinkedIn Ads

The most expensive channel per click (average CPC €6-12 in Spain), but with the highest conversion rate to a qualified lead in B2B. According to HubSpot (State of Marketing, 2025), LinkedIn Ads generates 277% more B2B leads than Facebook or X. Key formats: Sponsored Content to position content, Lead Gen Forms with pre-filled native forms, and Message Ads for direct outreach. It only makes sense if your average ticket justifies the CPL.

Microsoft Ads (Bing)

The forgotten channel, with a CPC 15-20% lower than Google and an audience with greater purchasing power (corporate profile, desktop users). For B2B and professional services, Microsoft Ads offers a ROAS that many agencies ignore because they don’t bother to diversify.

Remarketing and retargeting

Only 2-3% of visitors convert on the first visit, according to data from Invesp (Conversion Rate Optimization, 2025). Remarketing reaches the remaining 97% with personalised ads based on their behaviour. A PPC agency that doesn’t configure remarketing from day one is leaving money on the table. Combined with lead nurturing, remarketing closes the acquisition cycle.

# How much it costs to hire a PPC agency in Spain

One of the points that generates the most confusion. The most common pricing models in the Spanish market:

• Fixed monthly fee: between €500 and €3,000/month depending on complexity. The most transparent model. Includes management, optimisation and reporting.
• Percentage of ad spend: between 10% and 20% of the ad spend. It makes sense when the advertising budget is high (>€5,000/month). Problem: the agency may have an incentive for you to spend more, not to convert more.
• Fee + percentage: hybrid model. Base fee (€300-800) + a smaller percentage (5-10%). Balances commitment and scalability.
• Performance fee: the agency charges based on results (CPL, CPA, ROAS). The riskiest and least frequent. It only works with impeccable tracking and very clear agreements.

Realistic reference for SMEs in Spain: a budget of €1,000 to €3,000/month in ads needs a management fee of €500 to €1,500/month for the agency to be able to dedicate the necessary time. An agency that charges €200/month to manage your campaigns cannot do real optimisation.

# 7 criteria for choosing a PPC agency

Not all agencies that say they do PPC do it well. These are the 7 criteria that separate the agencies that generate ROI from those that generate pretty reports:

1. Certifications and partners

Google Partner or Premier Partner is a minimum, not a differentiator. What matters is whether they have active certifications in Search, Shopping, Display and Measurement. Ask about the individual certifications of the managers — having a certified Google Ads specialist makes the difference, not just the company’s.

2. Sector specialisation

A PPC agency that manages ecommerce, B2B SaaS, dental clinics and restaurants at the same time cannot master any of them. Ask for case studies in your specific sector with data: investment, CPL, ROAS, period.

3. Account ownership

Your Google Ads account, Meta Business Manager and any platform must be yours. If the agency works from its account and you have no access, you lose all the history the day you change. An absolute red flag.

4. Tracking and attribution

Ask how they measure results. If the answer is “clicks and CTR”, look for another agency. A professional PPC agency implements conversions with Google Tag Manager, integrates with your CRM to measure SQL and pipeline, and distinguishes between first-click, last-click and data-driven attribution.

5. Optimisation frequency

A PPC account needs review at least weekly. Keyword negativisation, bid adjustment, ad testing, budget reallocation. If your agency reviews your account once a month, it is charging you for doing nothing in between.

6. Transparency in reporting

Reports that show vanity metrics (impressions, clicks, CTR) without connecting to business results (leads, pipeline, sales) are noise. Demand dashboards with real performance marketing metrics: CPL, CPA, ROAS, value of the pipeline generated.

7. Integration with the rest of the strategy

PPC does not work in isolation. It needs optimised landing pages, content for remarketing, alignment with SEO to avoid cannibalisation (having an SEO expert who coordinates both channels is key), and connection with the CRM. A PPC agency that does not talk to the SEO or content team is working blind. At CRONUTS.DIGITAL we integrate PPC with a complete digital strategy because channels that talk to each other convert more than those that compete.

“Badly managed PPC is the fastest way to burn budget. Well managed, it is the lever with the most predictable return in digital marketing. The difference is measuring what matters: pipeline, not clicks.”

Albert Puig Navàs, CEO of CRONUTS.DIGITAL

# Mistakes that destroy the ROAS of your PPC campaigns

After auditing hundreds of Google Ads and Meta Ads accounts, these are the most frequent mistakes:

• Not negativising keywords: without an updated negative-keyword list, you are paying for irrelevant searches. It is the most common leak and the easiest to fix.
• Sending traffic to the home page: each campaign needs its specific landing page. The home does not convert paid traffic because it is not designed for it.
• Not configuring conversions correctly: if you measure “visits to a thank-you page” instead of “lead validated in the CRM”, your ROAS data is fiction.
• Budget spread across too many campaigns: €200 spread across 15 campaigns doesn’t give enough data to optimise any of them. Concentrate and scale what works.
• Ignoring the Quality Score: Google penalises low-relevance ads by charging you more per click. Improving the Quality Score in SEM reduces the CPC and improves the position.
• Not doing remarketing: 97% of your visitors leave without converting. Not reaching them again is giving away customers to the competition.
• Relying on Google automations without supervision: Performance Max and Smart Bidding work, but they need human supervision. Automations optimise what you tell them to optimise. If the objective is badly defined, the AI amplifies the error.

# PPC for B2B vs PPC for ecommerce

It is not the same strategy. The differences change the entire approach:

• Objective: B2B seeks qualified leads (demos, forms, calls). Ecommerce seeks direct purchases. The main metric changes: CPL vs ROAS.
• Buying cycle: B2B can take weeks to months. Ecommerce can take minutes. B2B campaigns need more remarketing sequences and nurturing content.
• Channels: B2B performs better on Google Search + LinkedIn. Ecommerce performs on Google Shopping + Meta Ads + Performance Max.
• Landing pages: B2B needs landing pages with a clear value proposition, social proof and a short form. Ecommerce needs optimised product pages with impeccable UX.
• Minimum budget: B2B can start with €1,000-2,000/month if focused on high-intent keywords. Ecommerce needs more volume to feed the algorithms (€2,000-5,000/month minimum).

For B2B companies that need a broader view than just PPC, working with a B2B digital marketing agency that integrates paid with SEO, content and automation maximises the return on each channel.

# How CRONUTS.DIGITAL works as a PPC agency

We don’t manage campaigns. We build paid-acquisition systems that integrate with the whole digital strategy. Our method in four phases:

1. Account audit: we review structure, keywords, ads, landing pages, tracking and budget. We identify leaks and quick opportunities.
2. Strategy and structure: we design the campaign architecture aligned with your funnel. Each campaign has an objective, an audience and a specific landing page.
3. Activation and testing: we launch campaigns with A/B tests on ads, landings and audiences. The first 4-6 weeks are of accelerated learning.
4. Optimisation and scaling: weekly review of metrics, budget reallocation, keyword negativisation, bid adjustment and progressive scaling of what converts.

The result: PPC campaigns connected with your CRM, your sales team and your global marketing strategy. Not clicks. Customers. Artificial intelligence in marketing already makes it possible to optimise bids, predict conversions and personalise ads at scale. If your PPC agency doesn’t use it, it is competing with one hand tied.

# PPC and SEO: why you need both and how to integrate them

PPC and SEO are not mutually exclusive strategies. They are complementary. PPC captures existing demand immediately. SEO builds organic visibility in the medium term (and choosing the best SEO agency is as important as choosing the PPC agency) for the same searches without cost per click. The companies with the best digital performance use both channels in a coordinated way.

The key is to avoid cannibalisation. If your website already ranks on the first page for a keyword, bidding for it on Google Ads may not make sense. On the other hand, if your keyword analysis identifies high-intent terms where you have no organic presence, PPC covers that gap while SEO works. PPC data (converting keywords, working copy, better-performing landing pages) directly feeds the SEO strategy.

# Landing pages for PPC: the link that decides whether you convert

The best PPC campaign in the world fails if it sends traffic to a page that doesn’t convert. Conversion landing pages for PPC must meet specific requirements: message match with the ad, a single clear CTA, visible social proof above the fold, a short form (3-5 fields in B2B) and a load speed under 2 seconds.

Each campaign needs its landing page. Google Ads’ Quality Score penalises generic landing pages with higher CPCs. A professional PPC agency designs, tests and optimises landing pages as an integral part of the management, not as an extra.

# Automation and AI in PPC campaigns: what works and what doesn’t

Google has aggressively pushed automations: Smart Bidding, Performance Max, Demand Gen campaigns. The reality is nuanced. Automations work when they have enough data (minimum 30-50 monthly conversions), when the conversion objective is well defined and when there is constant human supervision.

Artificial intelligence applied to marketing goes further. Third-party tools make it possible to predict which creatives will work best, automate the generation of ad variants at scale, and optimise budget distribution across channels with predictive models. The role of a PPC agency in 2026 is no longer just to bid for keywords: it is to orchestrate a system where humans and algorithms work together to maximise the return.

# PPC metrics that matter and the ones that are noise

The metrics your PPC agency must report connect directly with your business:

• ROAS (Return on Ad Spend): revenue generated for every euro invested. The queen metric for ecommerce.
• CPA (Cost per Acquisition): how much each conversion costs. Essential for B2B.
• CPL (Cost per Lead): must be measured together with lead quality (SQL rate).
• Quality Score: higher QS = lower CPC = more clicks with the same budget.
• Share of Voice (SOV): percentage of possible impressions you capture. Indicates scaling headroom.

Impressions, clicks and CTR are useful operational metrics, but they should not lead the monthly reporting. Connect with your global digital marketing KPIs for the complete picture.

# Advanced remarketing: how to recover the 97% that leave without converting

Only 2-3% convert on the first visit. Remarketing reaches the rest with personalised ads based on their behaviour: page visited, resource downloaded, abandoned cart. The most effective strategies combine dynamic ads with time-based sequences (a different message at 3, 7 and 14 days).

Integrated with lead nurturing by email, remarketing closes the full cycle. A digital marketing agency for SMEs that integrates PPC with remarketing and nurturing maximises the value of each paid visit.

# PPC and GEO: how generative search changes the game

Generative-AI search engines (Google AI Overviews, ChatGPT, Perplexity) are transforming PPC. AI Overviews reduces organic clicks and pushes more users towards paid ads, which means more competition for the ad inventory and potentially higher CPCs.

The strategic response is to diversify. Don’t rely only on Google Search, but combine with display advertising, Meta Ads, LinkedIn and Microsoft Ads. In addition, optimising landing pages for Generative Engine Optimization (GEO) ensures your brand appears cited in generative answers without cost per click. The PPC agency of the future integrates paid media with GEO to maximise visibility across every search format.
