Budget and Bid Strategies
Before your ads can run, you need to set your campaign's budget. You'll also need to choose a bid strategy type, and optionally set keyword level match type bids. Depending on the type of campaign you are running, see the following sections for more details.

Your budget tells Bing Ads how much you want to spend on your campaign. You can set a daily budget for each campaign and when you reach your budget, Bing Ads will stop displaying your ads until the next day or month. Keep your advertising costs under control by keeping track of your budget.
With shared budgets you can set a single daily budget that can be used by any campaign within the same account. This enables you to efficiently distribute a single daily budget across all campaigns or across a defined group of campaigns within your Bing Ads account.
You might need to code for shared budgets in the Bing Ads platform, even if you do not plan to use shared budgets. For more details and to determine whether the campaign uses a shared budget, check the value of the BudgetId element (Campaign object) or Budget Id field (Bulk (Campaign object) record).
The Bing Ads API supports the DailyBudgetAccelerated and DailyBudgetStandard values as defined in the BudgetLimitType value set.
Show your ads for every relevant search, spending at an accelerated rate until you run out of budget for the day. When the daily budget limit is reached, your ads will stop displaying until the next calendar day.
Consider using this option if you want your ads to show more frequently earlier in the day until your budget is reached, to maximize the number of impressions.
Show your ads evenly every day throughout the month so you don't run out of budget early in the month. If the click rate is higher than expected, the rate of spend may be slowed to ensure that the budget is available until the end of the day; however, you won't exceed the estimated monthly budget.
This is a great option if you have a limited budget and want your ads to show evenly throughout the day. This way, your ads won't show all at once in the morning, using up your limited budget early in the day. You will also be able to monitor your budget on a daily basis, making adjustments as necessary, to maximize your budget.
Before you can submit your ad campaign, you need to set a campaign budget amount and select a budget type. Don't worry, you can change your budget amount and budget types at any time. Changes to your budget generally take effect within an hour or so. For a high level introduction to campaign budgets, see What are my budget options?
If you create a campaign and specify a daily budget, the service calculates the monthly budget limit by multiplying the daily budget by the number of days in the month. The service calculates the new monthly budget at midnight (in the campaign's time zone) on the first day of each month. If the daily budget amount or calculated monthly budget amount is depleted, the campaign is paused automatically. The calculated monthly budget must be within the allowed range for the currency. For more information about minimum and maximum budgets allowed, see Currencies.
If you update a campaign that specifies a daily budget on the first day of the month, the service also calculates the monthly budget limit by multiplying the daily budget by the number of days in the month. However, if you update the daily budget after the first day of the month, the service uses the following formula to calculate the monthly budget.
Monthly budget = month-to-date spend + daily budget * (days remaining in the month, including today)
For example, if you change the daily budget to $10 on July 15th, and you have spent $250 of the $400 budget, the new budget will be $420, which is calculated as $250 + $10(17).
The service will use the new monthly budget for the remainder of the current month, but for subsequent months, it will calculate the monthly budget by multiplying the daily budget amount by the number of days in the month.
The service will update the monthly budget of an existing campaign by using the new formula only if you update the campaign's budget; otherwise, the monthly budget remains unchanged and is enforced.
Bid Strategy Types
Your bid strategy setting tells Bing Ads how you want to manage your bids. Whichever bid strategy you use, Bing Ads will always respect your budget limit.
The Bing Ads web application uses the term Bid strategy, the Bing Ads Bulk API uses the Bid Strategy Type column for upload and download, and the Bing Ads Campaign Management API derives several bid strategy objects from the BiddingScheme object.
The following bid strategy types are available per campaign type. For more information see the Automatically optimize your campaign with bid strategies help article.
|Bid Strategy Type||Campaign Types|
For campaigns of type Shopping only the EnhancedCpc bid strategy can be used, and you must be in the Bing Shopping Enhanced CPC pilot. The pilot ID is 340.
If the campaign bid strategy type is set to MaxClicks, MaxConversions, or TargetCpa, the behavior of existing features will change unless you set an individual ad group's or keyword's bid strategy to ManualCpc.
- You can continue to set the ad group and keyword bids; however they will not be used by Bing Ads.
- Bing Ads will periodically change your stored ad group or keyword bid settings. You can continue to set new bids, however Bing Ads may change them at any time using this bid strategy type.
- You can continue to set bid adjustments e.g. for age, gender, or location; however, the multiplier will inform rather than directly modify or override the automated bid. For auto bidding the multiplier is used as a weighted percentage to inform Bing Ads about how much you value the criterion relative to other criteria. For example, a -50% bid multiplier for a mobile device criterion with the Max Conversions bid strategy to indicate that you value conversions from mobile traffic half as much as other device types. The same bid multiplier with the Max Clicks bid strategy would indicate that you value clicks on mobile half as much as other device types. The valid range of values that you can use to inform auto bidding is -100.00 through 30.00.
- Whether you chose the DailyBudgetAccelerated or DailyBudgetStandard budget type, Bing Ads will use the DailyBudgetStandard budget type.
Also note that you must have conversion tracking (a UET tag and a conversion goal) set up for the EnhancedCpc, MaxConversions, and TargetCpa bid strategy types to work. See Universal Event Tracking for more information.
To set the MaxConversions or TargetCpa bid strategy types, the campaign must have at least 15 conversions in the last 30 days. If you try to add or update a campaign to use one of these strategy types, the requested operation will fail if there is not enough conversion history. If an active campaign uses one of these bid strategy types, and then ceases to meet the minimum conversion history requirement at any time, Bing Ads will stop auto bidding but will continue to use the DailyBudgetStandard budget type. For a new campaign we recommend that you start with EnhancedCpc and then when the campaign has enough conversion history, you can update it to use either the MaxConversions or TargetCpa bid strategy.
You can set your campaign's bid strategy to EnhancedCpc, MaxClicks, MaxConversions, or TargetCpa and then, at any time, set an individual ad group's or keyword's bid strategy to ManualCpc.
With the ManualCpc (manual cost per click) bid strategy, you set your ad group and keyword bids, and Bing Ads uses these bids every time. This is every campaign's default bid strategy unless you chose a different strategy when creating your campaign.
With the MaxClicks bid strategy, Bing Ads automatically sets your bids with the goal of getting as many clicks as possible with your provided budget.
Not everyone has this feature yet. If you don't, don't worry. It's coming soon.
The MaxClicks bid strategy is available only to advertisers from the following countries: Australia, Canada, France, Germany, India, Italy, Netherlands, Spain, Sweden, Switzerland, United Kingdom, and United States.
With the MaxConversions bid strategy, Bing Ads automatically sets your bids with the goal of getting as many conversions as possible with your provided budget.
Not everyone has this feature yet. If you don't, don't worry. It's coming soon.
The MaxConversions bid strategy is available only to advertisers from the following countries: Australia, Canada, France, Germany, United Kingdom, and United States.
With the EnhancedCpc (enhanced cost per click) bid strategy, you set your ad group and keyword bids, and Bing Ads automatically adjusts your bids in real time to increase your chances for a conversion. When we see a good opportunity, we increase your bid up to 30% to capitalize on it. On the other hand, if the patterns show that a conversion is less likely, we lower your bid as low as -100% i.e. will not bid on it. Up or down, this change will be made after we apply any bid adjustments you have set. If you haven't optimized your campaign yet, Enhanced CPC should reduce your cost per conversion and increase your total conversion count while respecting your current budget.
Differing from the MaxClicks, MaxConversions, and TargetCpa bid strategies, with the EnhancedCpc bid strategy, Bing Ads will not actually change your stored ad group or keyword bid settings. You can continue to set new bids, and we will use the new values as a starting point next opportunity; however, assuming the EnhancedCpc bid strategy remains in place, we will continue to modify the new bid from negative 100% through positive 30%.
The EnhancedCpc bid strategy is available to all advertisers worldwide. Note that we will only ?enhance? your bids when your ads serve in the following countries: Australia, Canada, France, Germany, India, Italy, Netherlands, Spain, Sweden, Switzerland, United Kingdom, and United States. When your ads serve outside of these countries, your manual bids are unaffected.
With the TargetCpa bid strategy, Bing Ads automatically sets your bids such that the target average CPA (cost per acquisition) is attained.
Not everyone has this feature yet. If you don't, don't worry. It's coming soon.
The TargetCpa bid strategy is available only to advertisers from the following countries: Australia, Canada, France, Germany, United Kingdom, and United States.
Keyword Match Types
Match type bids help Bing Ads determine how closely you want a search term or other input to match your keyword. The keyword that you bid on is compared to the user's search term in the order of Exact, Phrase, and then Broad.
An exact match results when all of the words in the keyword exactly match the user's search term.
If the plural form is not in your keyword list, the plural form of a keyword is also used in an exact match comparison. For example, if you specify an exact-match bid for the keyword, car, both car and cars will match. To prevent plural form of a keyword from matching, add the plural form to the campaign or ad group's negative keyword list.
If your keyword list does not contain the plural form of the keyword, all search results for the plural form will be included in the singular form of the keyword in the keyword performance report.
A phrase match results when all of the words in the keyword phrase are present in the user's search term and are in the same order. For example, the keyword phrase "red flower" will match the search term "big red flower" and "red flower", but not "yellow or blue flower" or "flower red".
A broad match results when words in the keyword phrase are present in the user's search term; however, the order of the words can vary. For example, the keyword red flower will match the search term red flower, flower is red, and other variations. It will also match the query red and the query flower.
Broad match can also match on synonyms and other semantic variations of the queries. For example, a search term for red carnation might result in your ad being displayed because carnation is a type of flower.
Because the search engine can vary its algorithms to expand queries to find broader matches by looking for synonyms and other meanings of the queries, the outcome can sometimes result in keywords being matched to irrelevant queries.
To reduce the chance of irrelevant ads being served to users and the quality score of those ads being affected due to low CTR, you can add any irrelevant queries to your list of negative keywords. To determine the irrelevant queries, see the Report Types.
You can also use the broad match modifier to require that specific terms in your keyword be present in the search term. To implement the broad match modifier, include a plus sign (+) in front of every term in the keyword that must be present in the search term. For example, if you bid on ?Hawaii hotels?, your ad could be served for the search queries, ?Hawaii beach hotels? and ?Hawaii rentals.? However, if you changed the keyword to ?+Hawaii +hotel?, the keyword would match only ?Hawaii beach hotels.?
If you include the broad match modifier on a keyword that specifies a phrase or exact match-type bid, the plus sign will be treated as part of the keyword and not as a modifier.
Bid and Delivered Match Types
You should set the ad group Search Bid that will be used as the default bid for Exact, Phrase, and Broad match types. You can then override the default by setting individual keyword level match types. Generally, the more precise you require the match to be, the higher conversion rates tend to be while impressions tend to decrease. Finding the right balance between conversions and impressions can help maximize the return on investment (ROI) of your campaign. If you're not sure which match type to use, we suggest starting with broad match. You can then use keyword performance reports over time to see which keywords lead to ad clicks and optimize your keyword list.
- If a majority of the keywords in the report are not related to your ad, you might want to use one of the more precise match types.
- For keywords that you want to continue leading to clicks, add them to your keyword list with a more specific match type such as Phrase or Exact.
- For keywords that you don't want leading to clicks, add them to your keyword list as negative keywords. For more information, see Negative Keywords.
Exact match is the most restrictive and broad match is the least restrictive match type. If the keyword matches by using the more restrictive match type, it will also match using the less restrictive match types. If the exact match comparison succeeds, the exact-match bid value is used if it exists; otherwise, it gets the bid value from the first less-restrictive match type that has a bid value (set at the keyword or ad group level).
If there is not an exact match, the phrase-match type comparison is used. If there is a match, the phrase-match bid value is used if it exists; otherwise, the broad-match bid value is used (set at the keyword broad match bid or ad group level search bid). If there is not a phrase match, the broad-match type comparison is used. If there is a match, the broad-match bid value is used (set at the keyword broad match bid or ad group level search bid).
The following table shows example keyword bid values for each match type, as well as the bid value that would be used based on the delivered match type if the keyword participated in the auction. The delivered match type (exact, phrase, or broad) identifies the comparison used to match the keyword to the user's query. For example, if the keyword is ?red shoes? and the user's query is ?pretty red shoes,? the delivered match type would be phrase. The delivered match type may differ from the match type you bid, for example if you bid on a broad match and the search term was an exact match.
|Exact Match Bid Value||Phrase Match Bid Value||Broad Match Bid Value||Delivered Match Type||Bid Value Used|
|No bid||No bid||0.10||Exact||0.10|
|No bid||No bid||0.10||Phrase||0.10|
|0.20||No bid||No bid||Exact||0.20|
|0.20||No bid||No bid||Phrase||None. Would not participate in auction.|
For Search and Content campaigns, take a look at the keywords you've created for your ad group. Are they all closely related? Do you want to add any others? Are you using a mix of match types? Consider using the Ad Insight Service to get ideas for additional keywords you might want to include in this ad group, and for suggested starting bids. For more information, see Budget and Bid Opportunities. You should create a keyword for each match type that you want to bid on. For example, to bid on exact-match and phrase-match for the keyword car, you must create two Keyword objects. Keep in mind that you cannot change a keyword's match type from one match-type bid to another match-type bid. For example, you cannot update a keyword from exact match to phrase match. Instead, you must add a new keyword that specifies a bid amount for the new match type. Optionally you may delete the original keyword if you do not want to bid on its match type.
You can also use negative keywords to prevent you ads from being served if the user's search query contains one of your negative keywords. For more information about negative keywords, see Negative Keywords.
A keyword is considered a duplicate if it is the same as another keyword, but its punctuation varies. This is called keyword normalization, a process where extraneous characters like punctuation marks and accents are removed from keywords and customer queries. Keywords are normalized when you add them to an ad group to avoid duplicates of keywords that normalize into the same form. Bing Ads flags duplicate keywords so you can remove them. Removing the duplicate keywords will save you time while still giving you thorough keyword coverage. If one of your keywords is marked as a duplicate, there is no reason to manage both of them. You can remove either the duplicate or the original keyword without impacting your campaign.
For example, let's say you add bike-repair as one of your keywords, and then also add bike repair. Your second entry (bike repair) would be marked as a duplicate. When someone searches for bike-repair, Bing Ads automatically removes the hyphen and displays ads for the search query bike repair, including yours, regardless of which variation you used (bike repair or bike-repair).
For a detailed list of normalized characters, see the Bing Ads help topic About duplicate keywords.
Please also note the following validation rules.
- Normalization is not case sensitive; bike repair and Bike Repair are treated as the same phrase. You'll see that if you enter a keyword with a capital letter, the capital letter is simply changed to lower-case.
- Normalization does not treat singular and plural forms of words as duplicates. For example, bike and bikes would be separate keywords. If you want to use both the plural and singular form of a keyword, bid on each separately. Similarly, normalization does not impact spaces within or between words, or apostrophes that are a part of a name. For example, bikerepair is not a duplicate of bike repair.
- As you create your keywords, also be aware of the rules they must follow. Here's some more information: Bing Ads policies.
