Facebook ads is still one of the most effective ways to generate new leads and customers – even in 2025. As competition intensifies, it becomes even more important to know the strategies that actually work to get the most out of your ads. This guide shows you how to practically use Facebook to generate more leads and customers for your business.

Why should you advertise on Facebook in 2025?
Even though new social media platforms continue to emerge, Facebook remains an essential source of potential customers. This is due to several factors:
Huge user base: Facebook still has millions of active users in Denmark.
Strong targeting: The ability to segment based on age, interests, behavior, and geography is unmatched.
Effective ad formats: From video and image ads to lead forms – you can create campaigns that suit any audience and objective.
The truth about getting more leads with Facebook ads in 2025
It’s no secret that Facebook ads have become more expensive over the years. As more advertisers fight for users’ attention, competition tightens, and ad auctions become more costly. Here’s the raw truth about what to expect:
Higher relevance requirements: Facebook’s algorithm filters harder, meaning only the most relevant ads are shown.
The importance of strong content: User-focused content that delivers clear value is rewarded with lower costs per click or conversion.
Conversion optimization pays off: The better your landing page and campaign setup convert, the greater the chance of getting a lower price per lead.
How to target and use data to get leads
One of Facebook’s biggest advantages is access to huge amounts of data. This data forms the basis of your audiences – and ultimately your success.
Demographics and behavior
- Demographics: Age, gender, location, job title, etc.
- Interests: Sports, cooking, technology, travel, etc.
- Behavior: Purchasing habits, device type, recent engagement.
Lookalike Audiences
With lookalike audiences, you can reach people similar to your existing customers or email lists. Facebook analyzes your submitted data and finds new users who most closely resemble them, increasing your chances of generating high-quality leads.
Retargeting
Advertising to users who have already interacted with your brand is a game-changer. Retargeting bridges the gap to potential customers who have shown interest but haven’t completed an action.
What does Facebook advertising cost in 2025?
The price of Facebook ads depends on several factors:
- Competition: High competition in your industry often results in higher click and conversion prices.
- Audience size: The narrower the audience, the higher the competition can be.
- Relevance score: The more relevant your ad is, the lower your costs are likely to be.
You can easily start with a smaller budget, test your strategy, and optimize over time. As you begin seeing results, you can scale up.
How Facebook’s ad system works in 2025
Facebook continues to use an auction model where:
- Bidding: You bid for a specific action (click, conversion, impression, etc.).
- Relevance evaluation: Facebook evaluates your ad content, targeting, and relevance.
- Ad delivery: The combination of bid and relevance that performs best wins the auction and gets shown.
If your ad is highly relevant, you can win auctions at a lower cost than competitors with higher bids but lower relevance.
How to identify the right target audience
Finding your ideal leads requires understanding who you want to reach. Methods include:
Detailed targeting: Combine age, gender, location, and interests for a relevant audience.
Custom Audiences: Upload your customer list or segment website visitors.
Interest lists: Facebook updates interests frequently—test which ones produce the best leads.
Optimize your campaign objective
Choose the right campaign objective to maximize your budget:
- Leads: Optimize for lead forms or Messenger leads.
- Conversions: Drive sales or sign-ups on your website.
- Engagement: Get more likes, comments, and shares (useful for warming up your audience).
The clearer your goal, the better Facebook can optimize your campaign.
Use different ad placements
Facebook offers many placements:
- Facebook feed
- Instagram feed
- Stories
- Messenger
- Marketplace
- Audience Network
You can choose Automatic placements, allowing Facebook to optimize where you get the best results.
Create effective Facebook ads
Your ad message must be sharp to attract leads:
- Eye-catching visuals: Images or short videos that quickly grab attention.
- Clear, concise text: Communicate value clearly.
- Strong CTA: “Get an offer,” “Contact us today,” or “Sign up here.”
What does Facebook marketing cost in practice?
Beyond ad spend, there may be costs for:
- Creative production (videos, graphics, copywriting)
- Campaign management or agency fees
- Software tools for tracking, split testing, and reporting
Always compare your investment with the leads and customers you gain.
Know your Customer Lifetime Value – The key to profitable Facebook marketing
What is Customer Lifetime Value (CLV)?
CLV shows how much a customer is worth to you over their entire relationship with your business.
Why CLV matters in Facebook ads
If you know a customer spends around 10,000 DKK over time, you can calculate whether the price you pay per lead is profitable. You might afford to pay 500 DKK per lead if the customer is likely to buy for much more.
How to calculate CLV
- Average order value
- Purchase frequency
- Retention period
Multiply these factors to estimate total customer value.
The potential for a strong investment in Facebook ads
With a clear understanding of CLV and correctly set campaigns, Facebook advertising can be extremely profitable. The secret to strong ROI includes:
- Continuous testing and adjustments
- Precise tracking (Facebook Pixel and Google Analytics)
- Scaling winning campaigns
- Fixing or stopping poor performers
What about the Boost button?
The Boost button is a quick way to promote posts directly from your page. But for lead generation, it’s too limited:
- Fewer targeting options
- No proper conversion tracking
- No A/B testing
- No retargeting flows
- Messy ad account structure
- Limited advanced formats
For serious lead generation, Ads Manager is the best choice.
6 disadvantages of boosting posts
- Limited ad formats
- Only one audience at a time
- Limited optimization
- No funnel-building options
- No split testing
- Clutter in your ad account
