Lower CPC on LinkedIn: bidding strategy and relevance score done right

LinkedIn Ads are expensive per click, but the price you pay is not fixed. Behind every impression sits an auction, and in that auction your relevance score weighs just as heavily as your bid. TL;DR: if you want a lower CPC on LinkedIn, first pick the right bidding strategy and then work on your relevance score through better ad copy, visuals and landing page. That way you get more qualified leads per euro without competing on budget alone.

How does LinkedIn actually decide your CPC?

On LinkedIn you do not pay a fixed price, you win an auction. Every time there is room to show an ad to someone in your audience, the system compares every advertiser that wants to reach that same person. The winner is not whoever bids most, but whoever brings the best combination of bid and relevance.

LinkedIn captures that relevance in a relevance score. The more relevant the platform believes your ad is for the recipient, the less you need to bid to win the auction. Two companies targeting exactly the same audience can therefore pay a very different CPC, purely because one of them is more relevant.

As a starting point, LinkedIn itself indicates an average CPC of a few euros per click. That is a starting point, not a fate. Your lever sits exactly there: you cannot make the price disappear, but you can push it down by being more relevant than your competitor in the same auction.

Which bidding strategies does LinkedIn offer?

LinkedIn works with three bidding strategies in Campaign Manager, the advertising platform of LinkedIn Ads. Each strategy makes a different trade-off between control, speed and cost management, and the right choice depends on where you are in your campaign.

• Maximum Delivery: LinkedIn spends your full budget and tries to squeeze as many results out of it as possible. You hand over control of your bid in exchange for speed. Ideal for gathering data quickly in the early phase and learning what works.
• Cost Cap: you set a target cost per result, and LinkedIn tries to stay as close underneath it as possible while spending your budget. You keep a grip on your cost per lead without steering every bid by hand. A good middle ground once you know roughly what a result is allowed to cost.
• Manual Bidding: you set the maximum bid per click yourself. Maximum control, but also maximum responsibility: bid too low and you win no auctions; bid too high and you burn through budget. Suited to those who already know the data and want to adjust deliberately.

Our honest advice: do not start with Manual Bidding straight away because it “feels cheaper”, because without data you are steering blind. Start with Maximum Delivery to learn, switch to Cost Cap afterwards, and only reach for Manual Bidding once you know exactly what a qualified lead is worth to you.

How do you lower your relevance score cost in practice?

The relevance score is your real lever, because it lowers your CPC without you having to bid a single euro more. The principle is simple: the better your ad matches whoever sees it, the cheaper LinkedIn lets you bid. The execution does demand discipline on three fronts that have to line up.

• Ad copy: write from the recipient’s point of view, not your own. A message that hits the pain or ambition of a specific role gets more response than a generic company claim. One clear call to action works better than three vague ones.
• Visuals: make sure your image reinforces the message and fits the context of a professional feed. Refreshing helps too, because ad fatigue pushes down your engagement and therefore your relevance.
• Landing page: this is the one most often forgotten. If your ad promises something and the landing page does not deliver, your visitor drops off. LinkedIn picks up those weak signals and your relevance falls. The page has to speak the same language as your ad.

Those three elements reinforce each other. A strong ad pointing at a weak page is wasted money, and a good page behind a vague ad gets too few clicks. Only when copy, visual and page carry the same promise does your effective cost come down.

If you scale up after that, Predictive Audiences help you find the right people more efficiently: by starting from your existing customer or lead data, LinkedIn looks for similar profiles, so your relevance grows along instead of getting diluted.

Do you steer on CPC or on cost per lead?

This is where the thinking error that costs many B2B companies money hides. Raw CPC is a vanity number if you look at it in isolation. A cheap click that leads nowhere is more expensive than a costly click that delivers a qualified lead.

In B2B, with a long sales cycle and multiple decision makers, that difference is crucial. You rarely sell on the first click. So the question is not “how cheap is my click”, but “how many qualified leads per euro do I get out of it, and how many of those become customers”. Optimising around CPC alone can push you towards a cheaper but worse audience.

One final honest caveat: sometimes it does not pay off to push your CPC down further. If your relevance score cannot go any higher and your audience is simply small and in demand, bidding up or switching channel is wiser than continuing to fight on price. Do read our guide on LinkedIn ads cost to judge when the budget pays for itself, and look at LinkedIn ad formats for the wider picture. If you want to steer on concrete enquiries, our approach to LinkedIn lead generation shows how to turn clicks into real leads.

What budget can you start with?

On LinkedIn you can already start with a modest minimum daily budget, enough to step into the auction and gather your first data. Just do not underestimate what “learning” costs: with the absolute minimum you gather data slowly and it takes a long time before your bidding strategy and relevance score settle.

For a Belgian B2B company with a fixed budget, the smartest move is not to pump in more money, but to make your euros work harder. Whoever takes their relevance score seriously structurally pays less for the same audience than whoever only turns the bid dial.

Frequently asked questions about LinkedIn bidding strategy and relevance score

Which bidding strategy gives the lowest CPC on LinkedIn?

No strategy lowers your CPC by itself. Maximum Delivery chases volume, Cost Cap guards your cost per result and Manual Bidding gives control. The real reduction comes from a higher relevance score. Start with Maximum Delivery and move to Cost Cap once you know what a lead is allowed to cost.

What exactly is a relevance score on LinkedIn?

It is LinkedIn’s estimate of how relevant your ad is for whoever gets to see it. That score weighs in the auction: the more relevant you are, the less you need to bid for the same audience. You influence it through ad copy, visuals and how well your landing page connects.

Can I lower my CPC without changing my bid?

Yes, and that is exactly the point. By making your ad more relevant you win auctions at a lower price, even at an equal bid. Work on a message that resonates with your audience, an image that fits and a landing page that delivers on the promise.

Why should I not steer on CPC alone?

Because a cheap click that does not convert ends up costing you more than a costly click that delivers a customer. In B2B, your cost per qualified lead and per customer is what counts, not the price of a single click. Steer on revenue and leads, not on the cheapest number.

Ready to get more leads per euro out of LinkedIn?

A lower CPC is not a trick, it is the result of the right bidding strategy combined with a relevance score that genuinely holds up. As a small team that moves fast, we would rather help you make your euros work harder than add more of them. We will look honestly at whether LinkedIn pays off for you and where your levers are.
