Should I use maximum delivery, cost cap or manual bidding on LinkedIn Ads?
TofuAnswer by the Tofu team · checked
Use maximum delivery if you want LinkedIn to spend your full budget; it's also the only option when you optimize for qualified leads. Use cost cap if you need the average cost per result to stay under a target on brand awareness, website visits, engagement, video views or lead generation. Use manual bidding if you want to set the exact bid and will check it often, or if cost cap isn't offered for your objective. Whichever you choose, start near the bid range Campaign Manager suggests. A bid that is too low won't win auctions.

Quick answer by situation
| If you… | Use | Why |
|---|---|---|
| Are new to LinkedIn Ads or must spend the whole budget | Maximum delivery | LinkedIn bids for you and aims to spend the full budget |
| Optimize lead gen for qualified leads | Maximum delivery | It's the only strategy LinkedIn offers for that goal |
| Need the cost per lead or per result to stay under a target | Cost cap | LinkedIn tries to keep the average under your cap |
| Can't find cost cap for your objective | Manual bidding | Manual is available for every objective |
| Have a big budget for a small audience | Manual bidding or cost cap | Maximum delivery may show your ad to the same member more than once |
| Use budget optimization (Dynamic Group Budget) | One strategy for the whole campaign | It's set at the campaign level; bid amounts stay on each ad set |
| Need a starting bid | The range Campaign Manager suggests | LinkedIn says bids that are too low aren't competitive |
What's the difference between the three LinkedIn bidding strategies?
LinkedIn's bidding help page compares them like this:
| Maximum delivery | Cost cap | Manual bidding | |
|---|---|---|---|
| How it works | LinkedIn bids for you using machine learning | You set a cost per result; LinkedIn uses it as a benchmark to set and adjust bids | You set the amount to bid in the auction |
| You pay by | Impressions (CPM) | Impressions (CPM) | CPC, CPM, CPV or CPS, depending on objective, ad format and optimization goal |
| Budget use | "Designed to deliver the full budget" | "Depends on the cost cap" | "Depends on the bid" |
| Objectives | All | Brand awareness, Website visits, Engagement, Video views, Lead generation | All |
| Best for, per LinkedIn | A hands-off approach that spends the full budget | A maximum cost per result with as many results as possible | Watching and updating bids yourself for maximum control |
Maximum delivery used to be called Automated Bidding or Auto Bid, so older guides may use those names. Campaign Manager picks a strategy for you based on your objective. To change it, open the ad set, go to Bidding, review your Optimization goal, then your Bidding strategy.
If you're new to LinkedIn Ads or must spend the whole budget
Use maximum delivery. LinkedIn's own bidding tips page says: "We recommend starting off with our maximum delivery bid type." You don't set a bid or a cap. Know what you're signing up for:
- It is "designed to deliver the full budget." LinkedIn also says actual daily spend "might be up to 100% higher than the daily budget amount on a given day." See why LinkedIn spends more than your daily budget.
- A new maximum delivery ad set enters a learning phase, and LinkedIn says "results might fluctuate" during it. Don't judge it on the first few days.
- It isn't available for Dynamic ad formats (jobs, spotlight and follower ads).
If you optimize for qualified leads
Use maximum delivery, because it's the only choice. When a lead generation ad set has a Conversions API integration set up, Campaign Manager selects qualified leads as the optimization goal by default, and LinkedIn says "the only bidding strategy available is maximum delivery." You can change the optimization goal, but LinkedIn's lead generation page says that if you do, "you can only select manual bidding as a bidding strategy."
If you need the cost per result to stay under a target
Use cost cap. By default, it tries to get the most results from your full budget. To set a target, LinkedIn says to "switch from the default to enter a goal KPI or bid amount." LinkedIn then uses your cost per key result, such as a lead, as a benchmark when it sets bids. Its table says cost cap is meant for "cost control, specifically for Leads."
Three things to know:
- The cap is an average, not a hard ceiling. LinkedIn calls it "an average amount Campaign Manager tries to stay under." Some results can cost more.
- You still pay by impressions (CPM), not per result.
- A low cap means less spend. LinkedIn says "the higher your cost cap or bid, the more competitive your ads." If your cap sits well below what others pay, the ad set may spend only part of its budget.
Cost cap is listed only for brand awareness, website visits, engagement, video views and lead generation. If Campaign Manager doesn't offer it for your ad set, use manual bidding.
If you can't find cost cap for your objective
Use manual bidding. It's available for every objective, and you pay by click, impression, video view or send depending on the objective, ad format and optimization goal. LinkedIn says manual bidding "gives you the most control over your bid amount, but it might not deliver the same ad set results." Check spend every few days and adjust. For lead generation ad sets, LinkedIn's help lists it as Manual bidding (Enhanced) for Sponsored Content and Manual bidding (Optimized) for Sponsored Messaging.
If you have a big budget for a small audience
Use manual bidding or cost cap, or lower the budget. LinkedIn's maximum delivery page warns that a large budget with a small audience can raise frequency and lower reach: "we might show your ad to the same member more than once." With manual bidding, LinkedIn bids the amount you set. With a cost cap, it aims to keep the average cost per result under your cap. Either way, spend follows your limit, not just your budget.
Some B2B advertisers go further. ZenABM, an ABM analytics vendor, recommends manual cost-per-click bidding for most account-based campaigns and keeps maximum delivery for short, time-sensitive pushes. That is one vendor's view, based on its own benchmarks.
If you use budget optimization (Dynamic Group Budget)
The objective, budget, schedule and bidding strategy are set at the campaign level, and every ad set in the campaign must use the same bidding strategy. If you pick cost cap or manual bidding, you still set the bid amount on each ad set. LinkedIn recommends following the bid suggestions at the ad set level. The minimum campaign daily budget with budget optimization is $30 USD.
If you need a starting bid
When you choose cost cap or manual bidding, Campaign Manager shows a suggested bid range for the ad set. LinkedIn bases it on what other advertisers targeting the same audience bid. For Sponsored Content with manual bidding, the suggestion also adjusts to your budget. LinkedIn's advice is to "follow the recommended bid amount shown in Campaign Manager to be competitive." The help pages we checked don't list fixed minimum bids, so the range in Campaign Manager is your guide.
Some practitioners start lower. ZenABM suggests starting manual bids 30% below LinkedIn's suggested range, then raising them 10 to 15% if an ad set spends less than 80% of its daily budget after 2 to 3 days. That is a third-party method, not LinkedIn advice, and it risks slow delivery at first. If you try it, watch spend closely in the first week.
What to avoid
- Setting a bid far below the suggested range, then waiting. LinkedIn says that if your bid "is too low, your ad set will not be competitive in the ad auction." An ad set that barely spends usually needs a higher bid or cap, not more time.
- Picking maximum delivery with a budget you don't actually want to spend. It is built to spend all of it.
- Changing strategy every few days. Each change resets what you're comparing. LinkedIn says new maximum delivery ad sets go through a learning phase where results might fluctuate, so give them time.
Where Tofu fits
Tofu Ads Agent (our product) has a bid optimization agent live for LinkedIn. Tofu's weekly bid and budget recommendations stay proposals until a person approves them. Campaigns Tofu builds are staged in your own ad account switched off, and a person turns them on. Tofu doesn't change how LinkedIn's strategies work: a cost cap is still an average, and maximum delivery still aims to spend the full budget.
