The Pros & Cons of Automated Bidding Strategies in Google Ads

In recent years, Google Ads has significantly pushed advertisers toward automated bidding strategies, promising better performance and less manual work. However, while these automated options have certainly evolved, many advertisers are still unsure about which strategy works best for their campaigns. In this guide, we will break down the various automated bidding strategies in Google Ads, highlighting their pros and cons to help you make the right choice.

What is Automated Bidding?

Automated bidding is a feature that adjusts your bids for you based on a range of signals like the likelihood of a click or conversion. Unlike manual bidding, where you manually set bids for individual keywords, automated bidding leverages Google’s machine learning to optimize performance automatically.

While this sounds like a dream come true for busy advertisers, the reality is a bit more complex. Each automated strategy works differently and may suit different goals. Let’s dive into the various strategies to help you understand which one may work best for your campaigns.

1. Manual CPC (Cost-Per-Click) Bidding

Pros:

  • Full control over individual keyword bids.
  • Ideal for beginners or those with smaller budgets.
  • Allows you to learn the platform without relying on Google’s algorithms.

Cons:

  • Time-consuming, as manual adjustments are needed.
  • You may not have access to the same data points as Google’s algorithms, limiting optimization.

When to Use: If you’re new to Google Ads or prefer full control over your bidding, manual CPC is a great place to start.

2. Enhanced CPC (ECPC)

Pros:

  • Combines manual control with automation.
  • Google adjusts bids up or down based on the likelihood of conversion.
  • Can improve CTR (Click-Through-Rate) and CVR (Conversion Rate).

Cons:

  • No cap on bid adjustments, meaning your CPC could rise unexpectedly.
  • Requires close monitoring to ensure profitability.

When to Use: Enhanced CPC is an excellent middle-ground between manual and fully automated bidding, suitable for campaigns that are already performing well but need a little extra boost.

3. Maximize Conversions

Pros:

  • Fully automated, focuses on driving as many conversions as possible within your daily budget.
  • Great for lead generation and businesses focused on conversion volume.

Cons:

  • Can drive up CPC if not monitored closely.
  • Requires accurate conversion tracking to function correctly.

When to Use: This strategy is ideal if your primary goal is to maximize the number of leads or sales, but keep an eye on your budget and conversion tracking.

4. Maximize Clicks

Pros:

  • Drives as much traffic as possible within your daily budget.
  • Ideal for brand awareness or list-building campaigns.

Cons:

  • Does not prioritize conversions, so you may get clicks but not leads or sales.
  • Can overspend if not carefully monitored.

When to Use: Use Maximize Clicks when you’re focused on increasing site traffic and awareness, rather than immediate conversions.

5. Maximize Conversion Value

Pros:

  • Focuses on generating high-value conversions, not just volume.
  • Option to set a target ROAS (Return on Ad Spend) for better control.

Cons:

  • Requires accurate tracking of conversion values.
  • Needs a lot of data for Google’s algorithm to optimize effectively.

When to Use: This strategy is great for eCommerce or businesses where the value of conversions varies. Make sure you have conversion values properly assigned to make the most of this strategy.

6. Target CPA (Cost Per Acquisition)

Pros:

  • Google optimizes bids to achieve your target CPA.
  • You get more control over cost-per-conversion goals.

Cons:

  • Requires enough historical conversion data to work properly.
  • Can limit Google’s ability to optimize if the target CPA is too low.

When to Use: Use Target CPA when you want to control costs and have enough conversion data for Google to make informed bidding decisions.

7. Target ROAS (Return on Ad Spend)

Pros:

  • Optimizes for high-value conversions.
  • You set a desired return on ad spend, and Google adjusts bids to meet it.

Cons:

  • Requires accurate value-based conversion tracking.
  • Works best with campaigns that have a high volume of conversions.

When to Use: Use Target ROAS when you’re focused on maximizing revenue rather than the number of conversions. This is ideal for businesses with varying conversion values, such as eCommerce.

8. Target Impression Share

Pros:

  • Ensures your ad appears in a specific percentage of available impressions.
  • Great for brand awareness campaigns.

Cons:

  • Does not focus on conversions or clicks.
  • Can drive up CPC if you aim for high impression share at the top of the page.

When to Use: Use Target Impression Share when brand visibility is your top priority. Be cautious of overspending if your goal is too aggressive.

9. Viewable CPM (Cost-Per-Thousand Impressions)

Pros:

  • Focuses on viewable impressions rather than clicks or conversions.
  • Ideal for awareness campaigns with a focus on display and video ads.

Cons:

  • May not drive conversions or site visits.
  • Impressions alone don’t guarantee engagement.

When to Use: Use this strategy for video or display ad campaigns aimed at boosting brand awareness.

Conclusion: Choosing the Right Bidding Strategy

With so many automated bidding strategies available in Google Ads, it’s important to choose the one that best aligns with your campaign goals. Manual CPC gives you full control, while strategies like Maximize Conversions or Target CPA offer advanced automation to optimize for specific outcomes. Remember, whichever strategy you choose, it’s essential to keep a close eye on performance and make adjustments as needed.
