Boost LinkedIn Ad ROI: Smarter Audiences and Attribution With OnSpot

As of 2025, LinkedIn has 1.2 billion members and LinkedIn ads are powerful—but they’re pricey, and scale is limited. Higher CPCs, smaller reach, and narrow placements mean most campaigns struggle to deliver real ROI. That’s where precision data comes in: OnSpot helps you overcome LinkedIn’s cost and targeting hurdles with custom audiences built on real-world behavior. In this post, we’ll cover the challenges of LinkedIn advertising, how to expand beyond its limits with behavioral data, and the tools to measure true campaign performance.

LinkedIn’s Role in Business Growth

This channel has traditionally been geared toward job seekers and professionals. However, LinkedIn can be a powerful tool to grow your business as well. There have been many improvements and ways to interact with users on the platform to generate leads, seek answers to common pain points from your customer base, and draw attention to that new product feature you just launched. 

The High Cost and Limited Audience Size of LinkedIn Ads

Compared to other social media platforms, advertising on LinkedIn tends to be relatively more expensive. The cost per click (CPC) or cost per impression (CPM) on LinkedIn can be higher, especially if you’re targeting a specific professional audience. This can limit the reach and effectiveness of your campaigns, particularly if you have a limited budget.

Additionally, compared to other social advertising platforms, LinkedIn has a more limited number of ad placements. This can result in increased competition for ad space and higher costs. It also means that your ads may appear less frequently, reducing their visibility and potential impact.

Lastly, LinkedIn’s user base, although substantial, is smaller compared to platforms like Facebook or Instagram. This means that the potential reach of your advertising campaigns may be more limited, particularly if you’re targeting a niche market or a specific demographic.

Expanding Scale With Behavioral Audience Extensions From OnSpot

OnSpot’s precision audience building tools allow you to identify and target specific visitors to any location in the U.S., including competitor businesses. Filter based on visit frequency and demographic characteristics to reach potential B2B contacts or employees for recruitment efforts. By utilizing these features, you can overcome LinkedIn’s limited ad targeting options.

Easily increase each and scale while maintaining your required targeting parameters by utilizing the OnSpot audience extensions:

• Lookalike – This patented tool takes into account both behavioral (real-world location visits) + demographic characteristics to expand your audience to those likely to convert.
• Social – Advertise to those in close proximity to your original target audience, particularly family, friends, and coworkers to amplify your message through real-world influencers.

OnSpot enables you to activate any audience created through multichannel campaigns, including on LinkedIn. By utilizing LinkedIn along with other channels, you can expand your reach beyond LinkedIn’s user base and target potential prospects or applicants where they may be actively searching for new employment opportunities. This helps overcome the challenge of LinkedIn’s audience size limitation and maximizes the visibility of your campaigns.

LinkedIn’s Ad Targeting Options

While LinkedIn offers robust targeting options based on professional criteria, such as job title, industry, and company size, the targeting capabilities may not be as extensive or granular as those provided by other platforms. Catering audiences toward business objectives while measuring results is critical on LinkedIn as much as any other channel. This can make it harder to precisely reach your desired audience or narrow down your targeting parameters.

Custom Audiences That Align With Business Goals Using OnSpot

Our suite of solutions will help you to build the correct audience to drive such business objectives, for example, following up with conference attendees or generating registrations for your next webinar. Custom audiences can be activated easily on LinkedIn and used with Dynamic Ads to add that additional layer of personalization and targeting needed to reach your objectives.

Utilize the OnSpot audience building capabilities in addition to the targeting options offered by LinkedIn to ensure your message reaches the right audience.

Measurement & Analytics on LinkedIn

LinkedIn provides analytics and reporting tools to measure the performance of your ads, however, these tools are less robust and detailed compared to other advertising platforms. This can make it challenging to accurately assess the effectiveness of your campaigns and optimize them accordingly.

Connecting Ads to Real-World ROI With OnSpot Attribution

The Attribution Reporting feature of the OnSpot platform allows you to track the success of your campaigns by tying the exposed audience to both physical and web locations they visited. This feature helps address the challenge of limited measurement and analytics on LinkedIn. By analyzing the campaign’s impact on driving your targeted audience to visit specific physical locations or websites, you can gain insights into the overall success of your campaigns and make data-driven optimizations.

For multichannel campaigns, measuring both in-person and web-based responses allows you to gain a comprehensive understanding of your campaign’s impact across different touchpoints, which can improve your B2B sales or employee recruitment efforts based on the combined response metrics that LinkedIn does not offer.

Note that LinkedIn regularly updates its advertising platform, introducing new features to address some of these challenges. We recommend consulting LinkedIn’s official resources to stay updated with the latest information to gain a comprehensive understanding of the current state of paid advertising on the platform.
