LinkedIn Ads has become the go-to platform for B2B marketers looking to generate high-quality leads, especially for SaaS companies looking to scale.
With over 35 million professionals in the UK using LinkedIn, it’s the perfect environment for targeting the entire decision-making unit, whether that is the decision maker, the user or wider.
We’ll walk you through seven proven LinkedIn advertising strategies tailored specifically for B2B SaaS companies in the UK.
Whether you’re looking to scale pipeline, reduce cost-per-lead (CPL), or increase lead quality, these techniques will help you get the most out of your LinkedIn ad spend.
1. Define Your Ideal Customer Profile (ICP) and going beyond just firmographics
LinkedIn’s targeting capabilities allow you to build audiences based on:
- Industry (e.g. fintech, healthtech)
- Company size (SMBs vs. enterprise)
- Job title and function (CTOs, IT Directors, Marketing Managers)
- Seniority and geography
But you can also go beyond this, targeting based on interests and job skills to further narrow your audience.
You can also narrow even further by targeting by company or individual.
For UK SaaS companies, this means you can target precisely the roles involved in software buying decisions. Align your ICP with your CRM or sales-qualified data to ensure tight targeting.
Pro Tip: Use exclusion filters to avoid wasting budget on irrelevant roles or industries and monitor through the campaign to identify segments that are not engaging.
2. Leverage LinkedIn Lead Gen Forms
Lead Gen Forms are a native ad format that pre-fill user information (name, email, company, job title) from LinkedIn profiles. They drastically reduce friction, leading to higher conversion rates than traditional landing pages.
For SaaS firms offering whitepapers, product tours, or webinar sign-ups, Lead Gen Forms simplify data capture and feed directly into your CRM or marketing automation tools.
There are occasions when a lead gen form is not the right choice however. The amount of information you can communicate to the user to persuade them to convert is low. So in situations where more information needs to be provided, driving users to a landing page will see increased conversions.
3. Use Intent Data to Target In-Market Buyers
SaaS buyers often do significant research before they’re ready to talk to sales. Platforms like Radiate B2B use intent signals—such as web behaviour and content consumption to identify companies actively researching your category.
By syncing this intent data with LinkedIn audiences, you can run ads only to businesses in an active buying cycle, improving lead quality and accelerating the sales process.
Combining intent data with your LinkedIn campaigns, SaaS companies see an increase in click rate and dwell time by 2-3x.
4. Run Conversation Ads for Mid-Funnel Engagement
Conversation Ads let you create interactive, chatbot-style experiences delivered via LinkedIn messaging. These are great for:
- Mid-funnel nurturing
- Driving demo requests
- Offering custom content based on user responses
They feel personal and tend to have higher open rates than email, especially when paired with intent-based targeting.
5. Optimise Ad Creative for Scroll-Stopping Performance
Even in a professional context, LinkedIn users scroll quickly. Your creative must:
- Have a strong, benefit-led headline
- Feature concise copy focused on business value
(e.g. “Cut onboarding time by 30%”) - Use high-quality, on-brand visuals that are bold and not templated.
Use A/B testing to iterate on messaging and imagery. For SaaS, consider visuals that show product UI, dashboards, or a use case in action. Using people’s faces in posts can also boost dwell time.
6. Segment Campaigns by Funnel Stage and more
One of the biggest mistakes B2B marketers make on LinkedIn is running generic campaigns.
Instead, segment by buyer journey first:
- Top of funnel: Brand awareness, educational content
- Middle of funnel: Case studies, webinars, comparison guides
- Bottom of funnel: Free trial offers, ROI calculators, demo ads
This ensures you’re delivering the right message at the right time, improving conversion rates and reducing wasted spend.
But you need to go further. Combining this segmentation with point 5 above to make the ad relatable to the companies being targeted as well as the funnel stage.
7. Track Metrics That Matter to SaaS
To justify your LinkedIn investment, focus on metrics tied to revenue:
- Cost Per MQL / SQL
- Demo request conversion rate
- Pipeline influenced
- Lead-to-close ratio
Use LinkedIn’s Insight Tag to track post-click behaviour and integrate with your CRM platform (e.g. HubSpot or Salesforce) to monitor full-funnel performance.
