About Search Ads 360 bid strategies
A bid strategy considers all of the campaigns, ad groups, keywords, and other biddable items that it's optimizing to be part of a single portfolio. Because bid strategies focus on maximizing performance of the portfolio as a whole:
- You'll get the best results if you create portfoliosthat share a business goal, such as campaignsin the same line of business, with similar margins, or with similar historical performance.
- You may see increased bids for stronger performing biddable items. In other cases, you may see increased bids for lesser performing biddable items when such an increase is likely to improve overall performance.
While you can apply bid strategies to specific ad groups or biddable items,bid strategies work better with larger portfolios. For example, if you put just 10 high-cost keywords into a bid strategy, there might not be much the bid strategy can do to improve performance. The larger the portfolio, the more trade-offs and hidden opportunities Search Ads 360 can find to improve overall performance.
Note that most Search Ads 360bid strategies can be applied to items in different engine accounts. That is, the portfolio can include items from all supported engine accounts. For example, you can apply a bid strategy to a Google Adscampaign, a Microsoft Advertising ad group, and Yahoo! Japan keywords.
History and predictable trends
To determine the optimal bids, bid strategies use the performance history of biddable items, online conversions, and if included, offlineconversions. As a bid strategy adjusts bids, it observes the effect of the change and then makes small, incremental adjustments if needed. Even thougheach cycle of adjusting, monitoring, and adjusting again may occur aboutevery six hours, you're likely to see improved performance over a longer period of time. Bid strategies avoid making abrupt, large changes, since that makes it more difficult to predict the outcome.
A bid strategy that uses offline conversions may stop adjusting the default bid of biddable items if offline conversion data isn’t uploaded regularly.
If a bid strategy detects predictable trends (such as recurring patterns on weekends), it can adjust bids to take advantage of the peaks and troughs within the trends. The stronger the trend, the more confident the bid strategy can be in making slightly more aggressive changes.
This is another reason that a larger portfolio performs better: the more historical data available, the more confident the bid strategy can be in making changes.
This type of predictive bidding requires ample historical data. As such, you will need a sufficient number of clicks and conversions for a bid strategy to take effect.
Effects of pausing a bid strategy
If you pause a bid strategy, bids will not be adjusted by the bid strategy. Keywords will continue to accumulate performance history, which may affect bid optimization if you resume the bid strategy. Keep this in mind as your ROI target may need to change. In addition, the bid strategy no longer displays a target bid.
