When it comes to B2B social advertising, one of the biggest questions marketers face is: which platform will deliver the results my business needs? LinkedIn has traditionally been the go-to platform for B2B thanks to its professional targeting options, but Meta is also an incredibly viable alternative, often overlooked.
Both platforms offer similar tools, including audience targeting, retargeting, custom audiences and lead generation. However, they approach targeting in different ways. LinkedIn focuses heavily on who someone is professionally, using factors such as job title, seniority, company and industry, while Meta can make greater use of interests, engagement, website activity and first-party data.
Understanding these differences can help B2B marketers decide how each platform could fit into their paid social strategy.
Job Titles vs Interests
One of the clearest differences between LinkedIn and Meta is how advertisers can define and refine their audiences.
Both platforms offer targeting options for job titles and interests. LinkedIn, however, is built around professional profiles, allowing advertisers to target characteristics such as job function, seniority, industry, company and skills. This can be particularly useful when a business has a very specific B2B audience.
Meta can also be used to target job titles alongside interests and other audience factors. However, the context in which people use each platform is different. LinkedIn is primarily a professional network, so users are more likely to provide detailed information about their job, company, skills and career. Meta is used much more for personal and social downtime, meaning users may have less corporate or professional information associated with their profile bio details.
This doesn't mean Meta can't be effective for B2B advertising. Instead, advertisers may need to take a broader approach to audience targeting, combining interests, engagement and job-related targeting where available. Meta can use signals such as the content users engage with, the pages they interact with and their activity on websites that use Meta Pixel codes to build an understanding of their interests and help identify audiences likely to be relevant to a business’s offering. These signals can then work alongside Meta's broader audience data and campaign optimisation to help reach potential customers.
In simple terms, LinkedIn has greater depth of professional information from user bio details, while Meta has a broader mix of personal, interest-based, behavioural and engagement data. For B2B advertisers, the right platform will depend on how specific the professional audience needs to be and what data is available to build and optimise the campaign.
Meta Pixel vs LinkedIn Insight Tag
There is also significant overlap between the platforms when it comes to website tracking and remarketing.
Meta Pixel has traditionally been used to help advertisers measure activity on their websites, understand conversions and build audiences based on website interactions. LinkedIn offers a similar capability through its Insight Tag.
For B2B businesses, this is particularly useful because the journey from seeing an advert to becoming a customer can take weeks or even months. Someone might see an advert, visit a website, read a case study and leave without making an enquiry.
Website tracking allows advertisers to build audiences around these interactions and continue communicating with people who have already shown an interest in the business.
Remarketing
Remarketing is particularly important for B2B advertisers because asking potential customers to purchase a product or service from your business is likely to prove unsuccessful if they are unaware of you in the first place.
Someone may initially see an awareness campaign before visiting the website. They might then download a piece of content, watch a video or return to the website several weeks later.
Both Meta and LinkedIn can be used to create audiences based on previous interactions, meaning businesses can move potential customers through different stages of the marketing funnel.
This allows social advertising to become more than simply a way of generating clicks. Instead, it can form part of a longer-term B2B nurturing strategy.
Lead Generation on Meta vs LinkedIn
Another area where Meta and LinkedIn have a lot in common is lead generation. Both platforms allow businesses to capture information from potential customers without necessarily requiring them to leave the social platform.
LinkedIn's Lead Gen Forms are designed with B2B audiences in mind and can automatically populate form fields with information from a user's LinkedIn profile. This makes it easier for users to submit their details, while advertisers can also ask for additional information to help qualify leads.
Meta also offers lead generation campaigns, allowing businesses to collect information such as names, email addresses, phone numbers and other qualifying details directly through forms on its platforms. Meta's lead forms can also use autofill fields, including contact and business information, making the process quicker for potential customers. These campaigns can be particularly useful for generating enquiries, sign-ups and other B2B leads.
The difference is less about whether the platforms can collect professional information and more about the data and targeting behind the lead. LinkedIn has access to detailed professional information through its members' profiles, while Meta can combine lead form data with its wider audience targeting. For B2B advertisers, both platforms can therefore support lead generation, with the choice depending on the audience, campaign objectives and type of lead the business is looking to generate.
Lookalike and Similar Audiences
Both platforms also provide ways for advertisers to expand beyond their existing audiences.
Meta has historically offered Lookalike Audiences, allowing advertisers to use an existing audience as a starting point for reaching additional people with similar characteristics.
This can be particularly useful for B2B businesses with a strong customer database. Rather than trying to manually define every characteristic of a potential customer, advertisers can use existing customer information to assist.
LinkedIn also offers audience expansion tools, and its current Auto-Targeting system combines professional audience information, platform signals and advertiser inputs to help build an audience.
This shows how both platforms are moving beyond the idea that advertisers need to manually define every aspect of their target audience.
Audience Scale and Reach
Another consideration is audience scale.
LinkedIn's professional focus is one of its defining characteristics, but Meta gives advertisers access to a much broader social audience across Facebook and Instagram.
For B2B advertisers, this creates an interesting consideration. LinkedIn can make it easier to identify people based on professional characteristics, while Meta can provide access to a much wider audience and use different signals to help identify potential clients.
This can make Meta particularly useful for businesses with broader addressable markets or those looking to build awareness among potential customers before they actively enter a buying journey.
Rather than viewing the platforms as direct replacements for one another, advertisers can consider how each one can contribute to different stages of the customer journey.
Time Matters
Perhaps the biggest difference between Meta and LinkedIn is the mindset of the person seeing the advert. People often use LinkedIn in a professional context, while Meta is where they go when work mode is switched off. They may be scrolling in the evening, watching videos or simply taking a break from their working day.
For B2B advertisers, this can be both an advantage and a disadvantage. On the one hand, users aren't necessarily thinking about work, researching suppliers or looking for business solutions when they see an advert. On the other, they are still people, not just job titles. Meta can give B2B brands an opportunity to reach decision-makers in a more personal environment, where interests, behaviours and everyday experiences can influence what catches their attention.
Whether this works for a particular B2B campaign will depend on the product, audience and objective. If you need to reach someone specifically in their professional role, LinkedIn's professional environment may be more relevant. If you want to build awareness, create demand or connect with people beyond their job title, Meta's more personal environment can offer a different opportunity.
Meta vs LinkedIn: Cost
Cost is another important difference between Meta and LinkedIn. LinkedIn advertising typically comes at a higher cost than Meta. UK benchmarks put LinkedIn CPC (cost per click) at around £2-£6.25, compared with roughly £0.50-£1.50 on Meta (actual costs vary depending on audience size and ad spend).
However, a lower cost per click doesn't necessarily mean a better-performing campaign. For B2B marketers, it's important to look beyond CPC and consider metrics such as cost per lead, lead quality and conversion rate. A more expensive click may deliver greater value if it reaches a more relevant audience and generates higher-quality leads.
Creative and Ad Formats Matter Too
Targeting is only one part of a successful paid social campaign. The creativity used to communicate with an audience is equally important.
Both Meta and LinkedIn offer a range of advertising formats, including image, video and carousel-based advertising, alongside lead-generation options.
This gives B2B brands the opportunity to move away from traditional corporate advertising and experiment with different types of content. Short-form video, customer stories, educational content, industry insights and thought leadership can all be used to capture attention.
This is particularly relevant on Meta, where users aren't necessarily visiting the platform with a professional mindset.
For B2B marketers, the challenge is therefore not just identifying the right audience, but creating content that makes that audience stop scrolling.
Which Platform Should B2B Advertisers Use?
The answer depends largely on the business, its audience and the data available to it.
LinkedIn is particularly useful when a campaign needs to reach people based on professional characteristics such as job title, seniority, company or industry. Its professional targeting options make it well suited to campaigns with clearly defined B2B buyer personas.
Meta provides a different approach. Its combination of audience signals, first-party data, website activity, engagement and automated optimisation can give B2B businesses another way to reach potential clients.
For some businesses, that could mean using LinkedIn to reach a highly defined professional audience, while using Meta to expand reach and retarget engaged users.
The two platforms can therefore work alongside each other rather than being viewed as direct alternatives.
Meta Doesn't Need to Be LinkedIn to Compete in B2B
The biggest takeaway is that Meta doesn't need to replicate LinkedIn's professional targeting capabilities to compete for B2B advertising budgets.
LinkedIn's strength comes from its understanding of professional identity. Meta's opportunity comes from combining its vast social audience with interests, engagement, first-party information and automated audience optimisation.
For B2B marketers, the question isn't simply which platform has the most targeting options. It's about which platform can provide the right combination of audience, data, creative, reach and optimisation for the campaign.
As social advertising continues to become more automated, the traditional approach of manually defining an extremely specific audience has become less important. Instead, the quality of the data and signals provided to each platform, combined with strong creative and meaningful conversion tracking, can play an increasingly important role in finding and converting B2B customers.
