How to Defend an Incumbent Position With LinkedIn Ads
How to Defend an Incumbent Position With LinkedIn Ads
If you’re the incumbent or market leader, you have customers and share that challengers are actively trying to take — and defending that position with advertising is as important as pursuing new business. The mistake incumbents make is playing only offense (chasing net-new) while neglecting defense, leaving their customer base exposed to competitors who are targeting exactly those customers. Defense means staying present with your customers so challengers can’t quietly pick them off, reinforcing why they should stay, and being the obvious choice before a competitor makes their case. This guide covers how to use LinkedIn Ads to defend an incumbent position, and why offense alone leaves you vulnerable.
Key takeaways
- As an incumbent, you have customers and share that challengers are trying to take.
- Defense matters as much as offense — your base is a target, not a given.
- Stay present with your customers so challengers can’t quietly pick them off.
- Reinforce why customers should stay and be the obvious choice before competitors make their case.
- Balance offense and defense — chasing only net-new leaves your base exposed.
Why do incumbents need to play defense?
Because your existing customers are exactly who challengers are targeting, and neglecting them leaves them exposed. As the incumbent, your customer base represents established revenue and market share — which is precisely what competitors want to take, so they aim their conquesting and their messaging at your customers, trying to convince them to switch. If you’re not also reaching your own customers to reinforce the relationship, you cede that ground: challengers make their case to your customers while you’re silent, and some customers listen.
This is why offense alone is a mistake for an incumbent. Pouring all your advertising into acquiring net-new business while ignoring your existing base treats your customers as secured when they’re actually under attack. Every customer a challenger takes is revenue and share lost, and the incumbents who lose position often do so not because they failed to grow but because they failed to defend — letting challengers erode their base while they focused entirely on new acquisition. Defense protects the position you’ve built, which is as valuable as the new position you’re pursuing.
What does defending your position look like?
Staying present with your customers and reinforcing why they should stay, so challengers can’t pick them off:
| Offense | Defense | |
|---|---|---|
| Target | Net-new prospects | Your existing customers |
| Goal | Win new business | Retain customers and share |
| Message | Why choose you | Why stay with you |
| Risk if neglected | Slower growth | Base eroded by challengers |
Defending means reaching your customers with reinforcement of the value they’re getting and why they should stay, so that when a challenger makes their pitch, your customers already have a strong relationship and clear reasons not to switch. It also means being present enough that challengers can’t quietly erode your base while you’re not looking — an incumbent who stays visible with their customers is much harder to displace than one who assumes the relationship is secure. This overlaps with retention advertising, but framed competitively: you’re not just keeping customers, you’re defending them against active attempts to take them.
How do you defend against competitor conquesting?
By reaching your customers before and as competitors target them, reinforcing the relationship so the challenger’s pitch doesn’t land. When a competitor runs conquesting campaigns aimed at your customers, those customers are being told why they should switch — and your defense is to have already established, and to keep reinforcing, why they should stay. An incumbent who maintains presence with their base, reinforcing value and the strength of the relationship, makes the challenger’s case harder, because the customer isn’t a neglected account open to a better offer but a well-served one with reasons to stay. The key is not to wait until you’re losing customers to defend them; by then the challenger’s message has already worked. Instead, defend proactively — stay present with your customers continuously, so your relationship is strong before any competitor targets them. This proactive defense is far more effective than reactive scrambling once churn to a competitor starts, because retaining a well-served customer is easier than winning back one who’s already being courted or has begun to switch. Defending your base is an ongoing posture, not a response to an attack in progress.
The incumbent-defense framework
Defend an incumbent position deliberately:
- Recognize your base is a target — challengers aim at your customers, so don’t treat them as secured.
- Balance offense and defense — pursue net-new, but don’t neglect defending your existing base.
- Stay present with customers — reach them continuously so challengers can’t quietly pick them off.
- Reinforce why they stay — the value and relationship strength that make a challenger’s pitch harder.
- Defend proactively — establish strength before competitors target them, not reactively after churn starts.
Why is proactive defense better than reactive?
Because retaining a well-served customer is far easier than winning back one who’s already being courted or has started to switch. If you only react to competitive pressure once you’re visibly losing customers, the challenger’s message has already done its work — your customer is now considering alternatives or defecting, and pulling them back is hard. Proactive defense, by contrast, keeps your relationship strong before any competitor targets it, so the challenger’s pitch lands on a customer who already has clear reasons to stay and a strong relationship with you. This is the same logic as air cover applied defensively: presence in advance is more effective than intervention after the fact. An incumbent who defends proactively — maintaining continuous presence and reinforcement with their base — rarely faces the crisis of mass defection, because their customers were never left exposed. An incumbent who defends reactively is perpetually fighting to recover ground already lost. The strategic point is that defense, like most of marketing’s most valuable work, compounds when done consistently over time and is far weaker when attempted only in response to an immediate threat, so the incumbent’s defensive posture should be ongoing rather than triggered by a competitor’s move.
Frequently Asked Questions
Q1. How do you defend an incumbent position with LinkedIn Ads?
Stay present with your existing customers, reinforce why they should stay, and be the obvious choice before competitors make their case — so challengers can’t pick your customers off. Balance this defense with your offensive net-new pursuit, and defend proactively rather than reacting after churn starts. Your base is a target, so defending it protects the position and share you’ve built.
Q2. Why do incumbents need to play defense?
Because your existing customers are exactly who challengers target — your base is established revenue and share that competitors want to take. If you don’t reach your own customers to reinforce the relationship, challengers make their case while you’re silent, and some switch. Incumbents that lose position often fail to defend, letting challengers erode their base while they focus only on new acquisition.
Q3. What does defending an incumbent position look like?
Reaching your customers with reinforcement of the value they’re getting and why they should stay, so when a challenger pitches them, they already have a strong relationship and clear reasons not to switch. It overlaps with retention advertising but is framed competitively — you’re not just keeping customers, you’re defending them against active attempts to take them.
Q4. How do you defend against competitor conquesting?
Reach your customers before and as competitors target them, reinforcing the relationship so the challenger’s pitch doesn’t land. When a competitor tells your customers why to switch, your defense is having established and continually reinforced why they should stay. A well-served, engaged customer is much harder for a challenger to win than a neglected account open to a better offer.
Q5. Should incumbents only focus on new customer acquisition?
No — focusing only on offense leaves your base exposed to challengers targeting it. Pouring all advertising into net-new while ignoring existing customers treats them as secured when they’re under attack. Every customer a challenger takes is revenue and share lost. Balance offense with defense, since protecting the position you’ve built is as valuable as pursuing new business.
Q6. Is defending customers the same as retention?
It overlaps but is framed competitively. Retention keeps customers by reinforcing value; incumbent defense does the same but specifically against active competitive attempts to take them. You’re not just preventing passive churn — you’re defending customers who are being actively targeted by challengers. The reinforcement is similar, but the context is a competitive fight for your base rather than general retention.
Q7. Why is proactive defense better than reactive?
Because retaining a well-served customer is far easier than winning back one already being courted or starting to switch. Reacting only once you’re visibly losing customers means the challenger’s message has already worked. Proactive defense keeps your relationship strong before competitors target it, so their pitch lands on a customer with clear reasons to stay — avoiding the crisis of mass defection entirely.
Q8. How do you balance offense and defense as an incumbent?
Pursue net-new business while also maintaining continuous presence with your existing base to defend it. Neither alone is sufficient — offense alone lets challengers erode your customers, while defense alone forgoes growth. The balance is running acquisition campaigns for new business and defensive reinforcement for your customers simultaneously, treating your base as a target to protect rather than secured revenue.
