How we work
AI-native: AI speeds up research, creative testing and reporting, and a senior specialist makes every call.

SaaS growth lives and dies by unit economics. A cheap sign-up that never activates is expensive; a pricey demo that becomes an annual contract is a bargain. As a SaaS marketing and PPC agency, we build acquisition around activated users, paying customers and payback period, whether you’re product-led, sales-led or both.

(01) Campaign structure

Campaigns built to win paying customers.

Each channel has a different job. Search captures people comparing tools right now, paid social and LinkedIn create demand among the right teams, and retargeting turns trials into paying accounts. This is the structure we’d typically build for a SaaS company.

Paid search

Google Ads & Microsoft Advertising
01

Category & use-case search

Campaigns for “software for…” and the jobs your product does, each sending people to the feature page that answers their search.

02

Competitor alternatives

“Alternative to” and comparison searches, with honest comparison pages that give switchers a reason to try you.

03

Optimised to paid accounts

Trial-to-paid and plan value sent back from your product or CRM, so bidding favours the sign-ups that turn into revenue.

04

Brand protection

A low-cost campaign on your product name, so review sites and competitors don’t take people already looking for you.

LinkedIn & paid social

LinkedIn, Meta & Reddit
01

Role-based targeting

LinkedIn campaigns aimed at the job titles and company sizes that buy your product, judged on qualified trials and demos.

02

Product-led creative

Short demos, feature walkthroughs and customer stories on Meta and LinkedIn that show the product doing the job.

03

Community platforms

Reddit and other communities added when your users genuinely gather there, with native, helpful messaging.

04

Lookalikes of best customers

Audiences seeded with your highest-value accounts, so the platforms look for more people like your best customers.

Retargeting & expansion

Google, YouTube, Meta & LinkedIn
01

Trial nurture

Messaging for people mid-trial, covering the features and use cases that tend to lead to an upgrade.

02

Pricing-page retargeting

Visitors who viewed pricing or started sign-up shown proof, FAQs and offers to remove the last objection.

03

Demand Gen & YouTube

Video and Demand Gen campaigns reaching people researching your category on YouTube, Discover and Gmail.

04

Payback-based targets

Targets set from customer lifetime value and payback period, not cost per sign-up. Try our LTV:CAC calculator.

The exact mix depends on your pricing, sales motion and trial model. We agree it with you up front, then shift budget towards what wins the most profitable customers.

(02) What we solve

Built for SaaS challenges.

01

MQL to SQL efficiency

We tune targeting and creative to the accounts that convert and expand, beyond the ones that simply sign up for a trial.

02

Product-led & free-trial funnels

Measurement that follows the user from ad to trial to activation, so spend optimises to real product engagement.

03

Contested category search

Category and competitor keywords are expensive. We balance them with problem-led and “alternative to” terms, and protect your brand from competitor bidding.

04

LTV:CAC discipline

Every channel is held to payback and lifetime-value targets, with budget flowing to what compounds.

(03) What we run

SaaS acquisition, by funnel motion

  • High-intent & competitor search

    Category, “alternative to” and competitor campaigns on Google and Microsoft, sending comparison-stage buyers to the most relevant pages on your site. See our PPC service.

  • LinkedIn & ABM for sales-led

    Company and job-title targeting, Lead Gen Forms and account-based campaigns for higher-value, demo-led sales. See our B2B approach.

  • Paid social for product-led growth

    Meta, Reddit and YouTube campaigns that drive self-serve sign-ups, optimised towards activation events. More on paid social.

  • Trial, activation & revenue tracking

    Product and CRM events (trial started, activated, converted to paid) sent back to Google, Meta and LinkedIn, so bidding learns which users become customers.

  • Retargeting, onboarding & expansion

    Sequenced retargeting for trialists who stall, and campaigns that support upgrades and expansion, which is where much SaaS revenue really comes from.

(04) How it works

From first click to paying customer

  1. 01

    Model your unit economics

    Target CAC, payback period and LTV:CAC by plan and segment, so we know what a trial, demo and customer can profitably cost before spending a pound.

  2. 02

    Build by funnel motion

    Product-led and sales-led journeys get separate campaigns, audiences, conversion events and targets, rather than being blended into one.

  3. 03

    Optimise to activation & revenue

    Activation and paid-conversion data flow back to the platforms, and budget moves to the channels and audiences that produce paying, retaining customers.

How we measure it · Click → Sign-up → Activated → Paying

  1. Stage 1

  2. Stage 2

  3. Stage 3

    Activation fed back to the platforms

  4. Stage 4

    Paying

    Campaigns judged on CAC and payback

Cheap sign-ups that never pay aren’t growth. We optimise to customers. Trials, activations and paid plans go back to Google, Meta and LinkedIn as offline conversions, sent server-side so fewer go missing.

(05) Measurement

Judged on payback, not sign-ups

Sign-ups are the easiest SaaS number to inflate and the least useful to optimise. We report on activated users, paying customers, CAC payback and LTV:CAC by channel. Platform metrics help with steering, but they aren’t the scoreboard. Check your own ratio with our LTV:CAC calculator.

Because platforms double-count and trials convert late, we look at blended CAC and cohort performance rather than any one dashboard, and add self-reported attribution to capture the influence tracking misses. That’s the principle behind commercial alignment over channel metrics.

(08) FAQ

SaaS questions.

01What does a SaaS PPC agency do?

A SaaS PPC agency, or SaaS marketing agency, runs paid search and paid social (Google Ads, Microsoft Advertising, LinkedIn and Meta) to win trials, demos and paying customers. What sets it apart from general PPC is what it optimises to: activated users, paid conversions and payback, sent back to the ad platforms from your product and CRM data, rather than raw sign-ups.

02Are you a SaaS marketing agency or a PPC agency?

Both, with a clear focus. Brightpace is a B2B SaaS marketing agency that specialises in paid acquisition: Google Ads, LinkedIn, paid social and the tracking that connects them to your CRM. We don’t do SEO, content or outbound, so we work alongside whoever handles those. Comparing options? See our guide to the best B2B SaaS marketing agencies in the UK.

03How do you reduce CAC and improve lead quality for SaaS?

By optimising to the leads that become customers, not the ones that fill in a form. We send qualified-lead, opportunity and closed-won stages from your CRM back to Google Ads and LinkedIn, so bidding learns what a good lead looks like, then hold every channel to payback and LTV:CAC targets and move budget to the funnels that acquire customers who activate, convert and expand.

04Can you support product-led and free-trial funnels?

Yes. We measure from ad to trial to activation to paid, and send those events back to the platforms, so spend optimises to real product engagement rather than just sign-ups.

05Which channels work best for SaaS?

High-intent Google and Microsoft search, LinkedIn for sales-led and account-based motions, Meta and Reddit for product-led growth, tuned to your funnel and deal size.

06Should we bid on competitor keywords?

It can work well for comparison-stage buyers, but test it carefully: clicks can be expensive and intent varies. Bidding on competitor names as keywords is generally allowed on Google, while using their trademarks in ad text can be restricted.

07How do you track trials that convert weeks later?

By sending trial, activation and paid-conversion events from your product or CRM back to the ad platforms, so campaigns get credit for, and optimise towards, the users who actually pay.

08Is LinkedIn worth it for SaaS?

For sales-led, higher-value SaaS, usually yes. Its company and job-title targeting is hard to match. For low-price, self-serve products, search and Meta often deliver customers more efficiently. See how we run LinkedIn ads for B2B and SaaS.

09How fast is onboarding?

Tracking is set up in the first two weeks and campaigns usually go live in weeks three to four. If you already have campaigns running, they keep running while we review and rebuild, so there’s no gap in lead flow. See how the first 90 days work.

10Can you take over from our current agency?

Yes. Your ad accounts and their history stay with you. We audit first, keep what works and change what doesn’t, so you don’t lose the data your campaigns have learned from.

11Do you work with SaaS companies outside the UK?

Yes. We work with SaaS companies across the UK and the EU, including campaigns that run in several countries at once, all managed remotely.

12Do you audit SaaS ad accounts?

Yes. Our fixed-price paid media audits cost £195 for one platform or £395 for up to three, covering campaigns, tracking and how trials and demos are measured, with a prioritised action plan you keep. Want to check the basics yourself first? Use our SaaS PPC audit checklist.

13What paid media reporting do SaaS clients get?

A weekly report and a live daily dashboard built around trials, activation, paying customers, pipeline, CAC and payback, alongside the platform numbers, plus a monthly call to agree the next month’s plan. Each report says what changed, why, and the specific recommendations for what happens next. See what the reports and dashboard look like.

14Do you work with high-ACV and enterprise SaaS with long sales cycles?

Yes. For higher-value, sales-led products we build demo-led search and LinkedIn account-based campaigns, and judge them on pipeline and closed revenue from your CRM rather than on lead volume. When deals take months to close, we optimise to earlier qualified stages, such as meetings booked or opportunities created, so the platforms get enough signal to learn while revenue catches up.

15Why do our leads look fine in Google Ads but poor in the CRM?

Usually because the ad platforms are optimising to form fills, and form fills are easy to win from people who will never buy: students, competitors, spam and the wrong company size. The fix is to send lead quality back: import qualified and closed-won stages from your CRM, add enhanced conversions, block form spam and judge campaigns on cost per qualified opportunity. We cover the set-up in our guide to offline conversion tracking for B2B.

16Can one agency run Google Ads, LinkedIn and Meta for SaaS together?

Yes, and it usually works better that way. Search captures people already looking, LinkedIn reaches the right companies and job titles before they search, and Meta suits product-led and lower-price products. Run as one plan, budget moves to whichever channel is bringing in pipeline at the best CAC, instead of each channel being judged on its own reported numbers.

17How much should a SaaS company spend on paid acquisition?

Work back from customer lifetime value and your target payback period. Once you know what a customer can profitably cost, we set budgets to hit that CAC and scale while it holds.
