Comparison Guide
For B2B marketers, LinkedIn Ads and Google Ads represent two distinct approaches to reaching business buyers. LinkedIn targets professionals by job title, company size, and industry — letting you reach decision-makers directly. Google Ads captures buyers when they're actively searching for solutions like yours. Both platforms can drive qualified B2B leads, but at very different cost points and use cases.
Quick Verdict
LinkedIn Ads excel at reaching specific professional personas and generating high-quality leads in enterprise and mid-market segments, but cost significantly more per click. Google Ads capture active purchase intent at a lower CPC and work well for B2B SaaS, services, and any business with strong search volume. For most B2B businesses, LinkedIn drives quality while Google drives volume.
| Criterion | LinkedIn Ads | Google Ads | Winner |
|---|---|---|---|
| Average CPC | $5–$15+ for most B2B niches | $2–$8 for B2B keywords | Google Ads |
| Professional Targeting | Excellent — job title, seniority, industry, company | Limited — demographic and keyword only | LinkedIn Ads |
| Lead Quality | Very high — decision-maker direct access | High — intent-driven but less role-specific | LinkedIn Ads |
| Ad Formats for B2B | Sponsored Content, InMail, Lead Gen Forms | Search, Display, YouTube, Demand Gen | Both |
| Minimum Budget | £3,000+/month recommended for meaningful data | £500+/month is viable | Google Ads |
| Brand Awareness | High — seen in professional feed daily | Lower — only shown during search sessions | LinkedIn Ads |
Choose LinkedIn Ads when you're selling to a specific professional audience — e.g. HR Directors, CTOs, or Finance Managers at companies with 50–500 employees. LinkedIn's targeting is unmatched for account-based marketing (ABM). It's the go-to platform for SaaS, professional services, recruitment, and enterprise software where the average deal size justifies a higher cost per lead.
Choose Google Ads when your B2B buyers are actively searching for solutions. If prospects Google 'best project management software for agencies' or 'IT support services London', Google Ads captures them at peak intent. Google is also more accessible for smaller B2B budgets and delivers leads faster, making it a better starting point for most B2B businesses new to paid advertising.
Use both when running a full-funnel B2B strategy. LinkedIn builds awareness among your target accounts and warms up decision-makers with thought leadership content. Google Ads then captures those same decision-makers when they search for solutions — a strategy called 'surround sound' marketing. Retargeting LinkedIn viewers with Google Display ads further reinforces your brand across their entire browsing experience.
It depends on your deal size. If your average contract value is £5,000+, a £100 cost per lead on LinkedIn can absolutely be justified. For smaller-ticket B2B offers, the economics may not work. Test with a £2,000–3,000 budget before committing to LinkedIn at scale. Track cost per qualified lead and cost per closed deal, not just cost per click.
Not directly. Google Ads offers some demographic targeting (age, household income) and customer match (uploading email lists), but it can't natively target by job title or company size. You can approximate professional targeting using industry-specific keywords and contextual placements on business websites, but LinkedIn's professional targeting is far more precise.
LinkedIn's minimum daily budget is low, but the effective minimum to generate meaningful results is around £2,000–3,000 per month. With LinkedIn's high CPCs, small budgets get exhausted quickly without gathering enough data for optimisation. Most agencies recommend at least a 3-month commitment at this budget level before evaluating ROI.
Both work well for SaaS, but in different ways. Google Ads captures prospects actively comparing software options (high purchase intent). LinkedIn Ads reaches decision-makers who haven't started searching yet — essential for enterprise deals where you need to influence multiple stakeholders over a longer sales cycle. Many successful SaaS companies use Google for inbound demos and LinkedIn for outbound enterprise prospecting.
