Paid Search Bidding Strategies: Understanding the Basics

Paid search bidding strategies form the bedrock of successful and profitable search engine marketing campaigns. While crafting compelling ads and optimising landing pages are essential, choosing the right bidding strategy is crucial to ensure your advertising spend is effective. Without a well-aligned strategy, you risk squandering your budget or missing out on potential returns.

In this comprehensive guide, we’ll delve into the nuances of paid search bidding strategies, explore best practices for developing a PPC bid strategy, and provide practical examples to illustrate how various approaches can enhance your campaign performance.

Paid Search Bidding: The Essentials of Paid Search Bidding Strategies

What Is Paid Search Bidding?

In paid search bidding, you set the amount you’re willing to pay for each click on your ad. Consequently, this decision directly influences your ad’s visibility and effectiveness. This bid, combined with other factors, influences your ad’s position on search engine results pages (SERPs). Your bid, therefore, plays a significant role in driving traffic to your site and achieving your marketing objectives.

However, simply placing high bids isn’t always the best approach. A higher bid can rapidly deplete your budget, leading to a high cost per acquisition if not managed correctly. This is especially problematic if your average order value is relatively low compared to your bid.

Types of Bidding Strategies

There are three primary types of bidding strategies: manual, automated, and smart. Each offers different levels of control and automation, catering to various needs and goals.

Manual Bidding

Manual bidding provides complete control over your paid search bidding process. You set bids for individual keywords and adjust them based on factors such as location, time of day, and device type. This method is particularly useful for those who prefer a hands-on approach and have a deep understanding of their campaign dynamics. However, it requires constant attention and adjustments to optimise performance effectively.

Automated Bidding

Automated bidding leverages machine learning to adjust bids automatically based on predefined goals such as maximising clicks or achieving a specific impression share. This strategy reduces the manual workload and helps in managing large-scale campaigns more efficiently. While it offers less granular control, it simplifies campaign management by handling bid adjustments on your behalf.

Smart Bidding

Smart bidding, or auction-time bidding, is a subset of automated bidding that uses advanced algorithms to optimise bids for each auction. It adjusts bids in real-time to maximise conversions or achieve a target return on ad spend (ROAS); thus, it enhances the efficiency of your paid search bidding strategy. Smart bidding strategies include Enhanced CPC, Target CPA, and Target ROAS, each designed to achieve specific performance objectives. This approach is particularly beneficial for those seeking precise, data-driven optimisation with minimal manual intervention.

Implementing Effective Bidding Strategies: Best Practices

To make the most of your paid search campaigns, it’s crucial to adhere to best practices for bidding strategies. These practices ensure your paid search bidding strategy aligns with your goals and, consequently, optimises performance.

1. Ensure Accurate Conversion Tracking

No bidding strategy will be effective if your conversion tracking is flawed. Accurate tracking is essential for understanding campaign performance and furthermore making informed adjustments. To verify your conversion tracking setup in Google Ads, navigate to the Goals tab and check the status of your conversions:

Unverified: Google has not yet verified your conversion tag.
No Recent Conversions: Your tag is verified, but no conversions have been recorded recently.
Recording Conversions: Conversions have been recorded within the past week.
Tag Inactive: Google cannot find your conversion tag.
Removed: The conversion action has been deleted.

2. Align Bidding Strategy with Goals

Your paid search bidding strategy should be tailored to your specific goals. For instance, if your objective is to maximise conversions, employing a Target CPA strategy might be suitable. Conversely, if you aim to increase brand awareness, a different approach may be required. It’s also important to set realistic goals; demanding a high ROAS without adjustments can lead to ineffective campaigns.

3. Embrace A/B Testing

Testing different bidding strategies helps determine which works best for your objectives. Start by running one strategy for a set period and then switch to another to compare results. In fact, this iterative process enables you to refine your approach based on empirical data. Once you identify an effective strategy, extend your testing to ad creatives to optimise further.

4. Avoid Frequent Changes

While regular evaluation of your paid search bidding campaigns is necessary, avoid making changes too frequently. Google’s algorithms require time to adjust and optimise bids, particularly with automated and smart bidding strategies. Frequent alterations can disrupt this process and hinder campaign performance.

Practical Examples of Bidding Strategies in Action

To illustrate the effectiveness of various bidding strategies, let’s explore real-world examples of how different approaches have been successfully implemented.

Simplifying Campaign Structures

A medical device manufacturer faced challenges due to a convoluted account setup with numerous ad groups and campaigns targeting mixed conversion goals. To address this, the campaign structure was simplified by consolidating campaigns and focusing on broad match keywords. This change prioritised online form completions over phone calls, leading to substantial improvements:

44% increase in patient leads from all paid media channels
66% increase in total lead volume
39% decrease in cost per lead

In contrast, another manufacturing client experienced a different issue where a precise bidding strategy was needed to compensate for lost organic traffic following a site migration. By creating specific audience subgroups, tailored ad copy, and integrating customer match blacklists, the results were notable:

87% increase in year-on-year revenue
45% decrease in cost per acquisition
68.4% increase in conversion value
22% decrease in cost per click
29x return on ad spend within three weeks

Leveraging Automated Bidding

To improve ad performance and reach more customers, we switched the e-commerce client to automated bidding strategies across multiple platforms. This change in paid search bidding proved highly effective; consequently, it significantly enhanced campaign performance. The results were impressive:

59% increase in Google conversions
153% increase in Facebook conversions
300% increase in Facebook conversion rate

Applying Smart Bidding

A cloud hosting provider required a swift increase in conversion rates with a lower ad spend, which led to a focus on paid search bidding strategies. By consolidating their campaigns and employing smart bidding strategies, they achieved significant results:

274% increase in overall conversions
59% increase in clickthrough rates
31% decrease in cost per acquisition
8% increase in conversion rate

The campaigns delivered the highest number of leads at the lowest historical cost.

Utilising Portfolio Bidding

To address the declining PPC leads and rising costs, we implemented a portfolio bidding strategy combined with smart bidding for the cloud-based software provider. This approach applied Google’s Target CPA bidding strategy across all campaigns, resulting in:

Improved efficiency in managing multiple campaigns
Enhanced performance across shared budget campaigns

Paid Search Bidding: Conclusion

In summary, paid search campaigns offer a range of possibilities, from boosting e-commerce sales to enhancing brand visibility. The key to success lies in selecting and implementing the appropriate bidding strategy for your goals. The examples highlighted demonstrate the potential for various strategies to deliver exceptional results.
