One of the most common questions businesses ask before investing in paid advertising is: which platform should we spend money on?
Between Google, LinkedIn, Meta and Reddit, the choice can feel overwhelming. Ultimately, it depends on what you are trying to achieve, who you need to reach and how ready your audience is to buy.
In this blog, we will be breaking down each platform so that you can have a better understanding of which ad platform is most suitable for your business.
The better your understanding is of what each platform is designed to do and how to get the most out of it, the stronger your returns and effectiveness are likely to be.
Google Ads: Best for Capturing Existing Demand
Google Ads is one of the most effective platforms for reaching people at the exact moment they are searching for a solution.
Google Ads is intent-based. It works well when someone is already searching for a product, service or solution.
That is what makes it powerful. If someone searches for a service you provide, they are actively looking. For businesses with clear demand, strong landing pages and proper conversion tracking, Google Ads can be one of the most effective channels.
The return on investment (ROI) potential is high. On average, pay-per-click (PPC) campaigns can generate around $2 for every $1 spent, while well-optimised campaigns can perform significantly better. But Google can also become expensive quickly. Search cost-per-click (CPC) averages around $5.34, and competitive keywords often cost more because you are bidding directly against competitors.
Google is best for businesses with existing search demand and a clear conversion journey. The mistake is assuming that because Google makes campaigns easy to launch, it makes them easy to run well. It does not. Campaigns need active management, keyword refinement, conversion tracking and regular optimisation.
LinkedIn Ads: Best for B2B Decision-Makers
LinkedIn is one of the most expensive major ad platforms, but it can also deliver some of the strongest business-to-business (B2B) lead quality.
Average CPCs often sit between $5 and $9, with some campaigns reaching $8–$12 or more. That makes LinkedIn difficult to justify for low-value offers, but useful for B2B businesses, software-as-a-service (SaaS) companies, consultancies, professional services and enterprise sales teams.
LinkedIn’s strength is precision. You can target by job title, industry, company size, seniority, skills and professional interests. Its ad formats, including document ads, click-to-message ads, connected TV ads and thought leader ads, can support reports, webinar registrations, credibility building and longer sales cycles.
LinkedIn is best used when the value of a lead is high enough to justify the cost. It is not a cheap lead-generation machine. It is a targeted B2B channel for reaching the right people with credible content over time.
Meta Ads: Best for Reach and Demand Generation
Meta Ads, across Facebook, Instagram, Messenger and the Audience Network, are interest-based and behaviour-driven. Unlike Google, Meta is not mainly about capturing people at the point of search. It is about creating demand, building familiarity and moving people into your funnel.
The cost advantage is significant. Average CPCs can be under $1 in many sectors, and cost per lead is often lower than Google Ads. Meta also offers powerful audience targeting based on interests, behaviours, demographics and engagement data.
This makes Meta useful for ecommerce brands, consumer businesses, events, lifestyle brands and companies with strong visual content. It is also effective for retargeting people who have already visited your website or engaged with your brand.
But Meta depends heavily on creative. Weak visuals, unclear messaging or generic offers will struggle. It often works best when connected to a wider content and conversion strategy.
Reddit Ads: Best for Niche Communities
Reddit is often overlooked, but it can be valuable for brands that understand their audience and know how to speak to them properly.
Its biggest advantage is cost efficiency. Reddit CPCs can range from $0.20 to $4.00, and cost-per-thousand impressions (CPM) typically sits around $2 to $5. That is significantly below LinkedIn and competitive with Facebook. It also has a low barrier to entry, with minimum budgets starting from around $5 per day.
Reddit is built around communities. Advertisers can target people based on interests, discussions and niche subreddits. For SaaS companies, tech brands, specialist products, gaming audiences and community-led businesses, this can be useful.
However, Reddit is not a platform where corporate language performs well. Users are quick to recognise generic advertising. Brands need to be useful, direct and human. Conversion windows can also be longer, often around 30–60 days post-click.
Summary: Which Platform Should You Use?
| Platform | Use It For | Cost Level | Best Fit | Point of Difference |
| Google Ads | Capturing active demand | High | Businesses with clear search demand | Reaches people when they are actively searching for a solution |
| LinkedIn Ads | Reaching B2B decision-makers | Very high | B2B, SaaS and professional services | Offers highly specific professional targeting by role, industry and seniority |
| Meta Ads | Awareness, retargeting and scalable leads | Low to medium | E-commerce, consumer brands and visual campaigns | Strong creative formats and a broad reach across Facebook and Instagram |
| Reddit Ads | Testing niche audiences and communities | Low | SaaS, tech and specialist products | Allows brands to reach highly engaged communities built around specific interests |
Paid advertising works best when the platform matches the objective. Whether you are using Google, LinkedIn, Meta or Reddit, the strongest results come from aligning the channel, audience and message with what your business is trying to achieve.
