Maximize ROI with Smart Bidding in Google Ads

Today, advertising campaigns require careful management and intelligent approaches to achieve the desired results. In a scenario of accelerated competition, technology stands as a powerful ally for the digital marketer. One of the tools that has revolutionized the online advertising world is Smart Bidding, a set of automatic bidding strategies developed by Google Ads.

Through the use of machine learning and artificial intelligence, these automated bidding strategies not only improve the performance of your campaigns, but also simplify and streamline the management process.

Find out in this article how intelligent automation can take your advertising strategies to the next level, freeing up your time and boosting your results.




What is Smart Bidding in Google Ads?

As we have told you, Google Ads Smart Bidding is a set of automatic bidding strategies that employ machine learning and aim to increase conversions or improve conversion value.

With Smart Bidding, algorithms are in charge of performing the appropriate operations to optimize results and free up time for the person managing the campaign. Through real-time and historical data patterns, the algorithm continuously learns from each user interaction and adjusts bids to achieve maximum performance. In this way, we are able to make better decisions in a smarter and faster way in advertising auctions.

Thus, Smart Bidding offers various bidding strategies that can be tailored to the specific needs of each campaign. Advertisers can choose from strategies such as "Enhanced CPC" to maximize clicks, "Target ROAS" to obtain a specific advertising ROI, or "Target CPA" to reach a desired cost per acquisition. This flexibility allows bids to be adjusted according to campaign objectives and advertiser preferences.

In fact, advertisers can leverage automated bidding strategies to reach their audience across different platforms and devices, thus maximizing the reach of their campaigns. Smart Bidding is not only limited to Google search, but also extends to other formats such as the Display Network, YouTube and mobile apps. 

Still, not all of the bidding process is automated. In order for advertisers to continue to have meaningful control over their campaigns, Smart Bidding allows advertisers to set daily budget limits, adjust bidding strategies at any time and get detailed reports on the performance of their ads.

In addition, Smart Bidding allows A/B testing with different bidding strategies to determine which approach works best for each campaign. By analyzing the results of these tests, advertisers can constantly improve their strategies and optimize their advertising spend over time.

Different Smart Bidding Strategies

Each of these Smart Bidding strategies suits different business needs and can be leveraged to increase the effectiveness of advertising campaigns.

Maximising conversions

The "Maximize Conversions" bidding strategy is ideal for advertisers looking to get the most conversions possible within a fixed budget or ROI. The main objective is to increase sales or lead generation in an efficient manner. To implement this strategy, it is necessary to establish a target Cost Per Acquisition (CPA), which represents the maximum amount you are willing to pay for each conversion.

The Smart Bidding algorithm, powered by Google's machine learning, analyzes historical and real-time data to adjust bids for each auction. The system prioritizes opportunities for clicks and conversions that have a high probability of meeting or exceeding the set target CPA. This maximizes the efficiency of the advertising spend and results in more conversions at the target cost.

The strategy is designed to capture as many leads as possible and convert them into desired actions, which translates into more conversions for your business. In addition, Smart Bidding adjusts bids in real time to adapt to changes in user behavior and market conditions, ensuring that investments are effective at all times.


CPA Objective

The "Target CPA" strategy is aimed at advertisers who want to reduce the cost of their advertising campaigns and, at the same time, increase sales or the number of customers. In this strategy, you must set a specific target CPA, which represents the maximum cost you are willing to pay for each conversion. The Smart Bidding system will focus on maximizing the number of conversions that can be obtained within the defined target CPA.

Google's algorithm constantly analyzes ad performance and makes adjustments to improve bidding efficiency. It always looks for opportunities that have a high probability of generating conversions at the target CPA, avoiding unnecessary expenses and optimizing the available budget.

The strategy allows to control and reduce costs per acquisition, which increases the profitability of advertising campaigns. In addition, advertisers can focus on achieving a specific cost per conversion, which helps them reach their business goals with greater precision.


Maximising conversion value

The "Maximize Conversion Value" strategy focuses on optimizing campaigns to obtain the highest possible conversion value within the budget. Instead of focusing solely on the number of conversions, this strategy takes into account the monetary value of each conversion.

To use this strategy, you need to assign a value to each type of conversion you want to track. This can be useful for assessing the importance of different actions, such as purchases, subscriptions or requests for quotes. The Smart Bidding algorithm analyzes the data and adjusts bids to prioritize the highest-value conversions, thus maximizing overall campaign performance.

By focusing on more valuable conversions, the strategy allows you to increase the value of conversions and ultimately improve your return on advertising spend. In addition, the strategy can be tailored to different types of conversions, prioritizing those that are most important to each business.


ROAS Objective

The "ROAS Targeting" strategy aims to maximize the return on advertising investment by focusing on achieving as many conversions as possible with a fixed ROAS (Return on Advertising Spend). ROAS represents the value generated for each monetary unit invested in advertising.

To use this strategy, a target ROAS value must be established. The Smart Bidding algorithm will adjust bids to maximize the relationship between the value generated by conversions and the cost of the advertising investment. In this way, it will focus on opportunities that have a high probability of generating conversions with a ROAS equal to or higher than the set target.

The strategy is designed to maximize the efficiency and profitability of your advertising campaigns, generating the highest possible return on investment. On the other hand, the ROAS objective allows you to focus on obtaining a positive return on your advertising investment.

As you may have seen, there is a key difference between Smart Bidding strategies and Google Ads automatic bidding strategies. This is that automatic bidding strategies focus on maximizing clicks or reaching an impression quota, while Smart Bidding strategies use machine learning to optimize bids based on specific business objectives, such as conversions, ROI or conversion value. Thus providing greater personalization and efficiency to obtain accurate and appropriate results for the advertiser's goals.


Advantages of implementing Smart Bidding strategies in your campaigns

Now that we have explored the different bidding strategies available in Smart Bidding, it is important to highlight the key advantages offered by this powerful automation tool.

  • Advanced machine learning

The use of machine learning algorithms allows Smart Bidding to process and analyze large amounts of data at an impressive speed. This makes it possible to make more accurate predictions about how different bidding strategies would affect conversions and conversion value. The ability to evaluate multiple factors and patterns in real time far exceeds the capabilities of human calculation, leading to smarter and more effective decision making.

  • Wide variety of contextual signals

One of the key advantages of Smart Bidding lies in its ability to optimize bids by taking into account a wide variety of contextual signals at the time of the auction.

By incorporating this information, Smart Bidding can adjust bids to match the specific preferences and characteristics of each audience, maximizing ad relevance and effectiveness.

  • Flexible performance controls

Smart Bidding offers flexibility to adapt to each advertiser's individual business objectives. You can define performance objectives, such as target cost per acquisition (CPA) or target return on investment (ROAS), and customize the settings according to your specific goals. This versatility allows you to have precise control over your campaigns and ensure they are aligned with your marketing strategies.

  • Transparent performance reports

To provide greater visibility into the performance of automated bids, Smart Bidding provides detailed reports that allow you to evaluate the performance of your campaigns. These reports provide valuable information on the behavior and results of bidding strategies, allowing you to identify potential errors or areas for improvement and make informed decisions to optimize your campaigns.

  • Saving time and simplifying management

With Smart Bidding, much of the bid management process is automated, which means marketers can free up valuable time to focus on other strategic and creative tasks. Bid automation and real-time optimization enable more efficient campaign management, freeing teams from the burden of manually adjusting bids.

Smart Bidding Best Practices

Implementing Smart Bidding in your Google Ads campaigns is just the first step to get the most out of this powerful automation tool. To get optimal results and maximize the performance of your ads, it is important to follow some best practices.

  1. Set clear objectives

    Before implementing Smart Bidding, clearly define your business and marketing objectives. Do you want to increase conversions, improve ROI or maximize conversion value? With clear objectives, you will be able to select the right bidding strategy that aligns with your goals.

  2. Allow time for optimization

    Smart Bidding uses machine learning to adapt and optimize bids in real time. However, it's important to give it enough time to gather data and adjust your strategies. Avoid making frequent changes or disabling Smart Bidding prematurely, as this can affect your ability to achieve optimal results.

    Consider segmenting your campaigns into groups with similar characteristics and objectives. By grouping ads with related themes or specific audiences, Smart Bidding can better adapt to each segment and optimize bids more precisely.

  4. Use valuable conversions

    For Smart Bidding to work effectively, make sure you have correctly set up the conversions that you consider most valuable to your business. This can include sales, contact forms or any other action that represents a relevant goal for your campaign.

  5. Monitor and analyze performance

    Regularly track the performance of your campaigns with Smart Bidding. Use reports and key metrics to evaluate the impact of automated bidding strategies on your business objectives. Identify patterns and trends to adjust and improve your campaigns accordingly.

  6. Experiment with bidding strategies

    Try different bidding strategies in Smart Bidding. You can test different bid targets to determine which one works best for your needs. Performing A/B tests or controlled experiments will help you discover which approach is most effective in achieving your goals.

  7. Maintain a good account structure

    An organized and consistent account structure is critical to the success of your campaigns. Group your ads and keywords logically, and use campaigns and ad groups to reflect different products or themes. A clear structure will allow Smart Bidding to better understand your goals and make precise adjustments.

  8. Optimize landing pages and ads

    Smart Bidding's performance can also be influenced by the quality of your landing pages and ads. Make sure your landing pages are relevant and offer a good user experience. Also, create engaging and relevant ads that align with your keywords and goals.

By following these best practices, you can get the most out of Smart Bidding and boost the performance of your Google Ads campaigns. The combination of smart automation and your marketing strategies will allow you to reach your goals more effectively and efficiently.


Combining Smart Bidding with other bidding methods

A smart strategy to take full advantage of Smart Bidding is to combine it with other bidding methods in your Google Ads campaigns. This combination allows you to use the best of both worlds, taking advantage of Smart Bidding's automation and machine learning, while maintaining some manual control in specific areas. Here are some effective ways to combine Smart Bidding with other bidding methods:

  • Smart Search campaigns with manual strategies

    Smart Search campaigns are an excellent option for advertising broad products or services. However, if you have specific products or services that require a more detailed approach, you can keep those campaigns under a manual bidding strategy. This will allow you to have greater control over keywords, bidding settings and targeting for those specific products or services, while the more general campaigns will continue to be managed by Smart Bidding.

  • Combine Smart Bidding with Manual CPC Bidding

    If you have highly relevant, high-performing keywords that you want to highlight, you can use a manual cost-per-click (CPC) strategy for those specific keywords. This will allow you to have more direct control over bidding and ensure that those keywords get the attention they deserve, while the rest of your keywords are still managed by Smart Bidding.

  • Device targeting with CPA Target Bidding

    If you want to segment your campaigns by device, you can use Smart Bidding with a targeted CPA strategy. This way, Smart Bidding will optimize bids for each device (such as desktop, tablet and mobile) based on your target cost per acquisition. This will allow you to have a device-specific approach while maximizing overall campaign performance.

  • Combine Smart Bidding strategies

    Within the same account, you can also combine different Smart Bidding strategies to suit the needs of each campaign or ad group. For example, you can use "Maximize Conversions" for a campaign that seeks to increase visibility, while employing "Target ROAS" for a campaign that has a more ROI-focused approach.

  • Experiments with bidding strategies

    Conduct controlled experiments where you test different bidding strategies with a percentage of your budget and compare the results with the current strategy. This will allow you to evaluate which combinations of bidding strategies offer the best performance and help you make informed decisions on how to optimize your campaigns.

  • Constant monitoring and adjustments

    Regardless of how you combine Smart Bidding with other bidding methods, it is essential to constantly monitor performance and adjust your strategies as needed. Analyze the performance of each strategy and make data-driven changes to maximize the performance of your campaigns.

Combining Smart Bidding with other bidding methods allows you to take full advantage of intelligent automation and machine learning, while maintaining strategic control in specific areas.



Implementing Smart Bidding in your Google Ads campaigns represents a crucial step in taking full advantage of the power of machine learning and intelligent automation. Thanks to this technology, digital marketers can free themselves from the burden of manual bid management and instead focus on creative strategies and informed strategic decision making.

With Smart Bidding, campaigns become more efficient and effective by adjusting bids in real time and optimizing performance to achieve business objectives. The different bidding strategies available, such as Maximize Conversions, Target CPA, Maximize Conversion Value and Target ROAS, offer the flexibility to adapt to the specific needs of each business.

In addition, combining Smart Bidding with other bidding methods and following best practices, such as setting clear objectives, properly segmenting campaigns, analyzing performance and making strategic adjustments, allows for even stronger results and continually improving ROI.
