Linkedin ads budget

Set the floor: $10/day minimum per campaign, $50-100 to optimize

LinkedIn's published minimum daily budget is $10/campaign. That's a hard floor, not a recommendation. The functional minimum where the bidding algorithm has signal to optimize is $50-100/day per campaign. Below $50/day, expect inconsistent delivery and unstable CPL. Don't fragment a $1,000/mo budget across 5 campaigns at $200/mo each - run 1-2 campaigns at $500-1,000/mo each.

Pick your spend tier - it determines what you can do

Tier 1 ($1.5k-3k/mo): single campaign, single format (thought leader ads), single audience, no testing. The algorithm needs all your spend concentrated to optimize. Tier 2 ($5k-15k/mo): 2-3 campaigns, primary format + 1 test format, A/B creative testing. Tier 3 ($25k-50k/mo): full-funnel structure - TOFU/MOFU/BOFU, 3-5 audiences, multiple formats, structured creative testing program. Tier 4 ($75k+/mo): ABM layers, lookalike audiences, retargeting funnels, multiple ICP segments running in parallel.

Allocate across the funnel based on tier

Tier 1: 100% TOFU (thought leader ads or document ads). Single objective: build awareness and a retargetable audience. Tier 2: 70% TOFU, 30% BOFU (Lead Gen Form ads to engaged audiences). Tier 3: 50% TOFU, 30% MOFU (Conversation ads, Carousel ads to mid-funnel), 20% BOFU. Tier 4: 40/30/30 with explicit ABM and lookalike layers inside TOFU.

# Sample $15k/mo Tier 2 allocation:
Thought leader ads (TOFU): $9k/mo / 2 campaigns / $150/day each
Lead Gen Form ads (BOFU): $4.5k/mo / 1 campaign / $150/day
Reserve / test budget: $1.5k/mo for new format or audience tests

Reserve 10-15% for the testing budget

Take 10-15% off the top before allocating to production campaigns. Use it for: new format tests, new audience tests, creative A/B/C tests. Without a dedicated test budget, every new test cannibalizes production campaigns and the production data gets noisy. The test budget runs as its own campaign at $50-100/day for 14-21 days, then you decide what graduates to production.

Set bidding strategy to match budget maturity

New campaigns (first 30 days): Automated bidding lets LinkedIn explore. Mature campaigns with clear CPL targets: Manual CPC capped at your tolerable CPL ÷ expected conversion rate. Target Cost bidding works at Tier 3+ when you have 50+ conversions/month per campaign to support the target. Below that conversion volume, Target Cost will throttle delivery to zero waiting for the right signal.

Build the budget pacing rhythm

Daily budgets pace within the day - LinkedIn doesn't burn the whole day's budget in the first 4 hours. Total-budget campaigns (lifetime budget) pace across the campaign duration. For ongoing-evergreen campaigns: use daily budgets. For time-boxed campaigns (event, launch, end-of-quarter push): lifetime budgets force pacing across the window. Check pacing weekly - underdelivery is the most common issue in Tier 1-2 accounts.

Review and reallocate monthly, not weekly

Tempting to reallocate budget weekly based on this-week's CPL. Bad idea - LinkedIn's algorithm needs 14+ days to stabilize and weekly reallocation amplifies noise. Set a monthly budget-review cadence: pull last 30 days of campaign performance, identify which campaigns hit their CPL/CPSQL targets, shift 10-25% of spend from underperformers to overperformers. Don't fully zero out underperformers - they may have audience reach you'll lose.
