The Power of Automated Bidding & Consolidation for PPC Optimisation
Problems with Bid Algorithm Changes
Automated bidding can bring plenty of benefits, but changes to bid algorithms often come with their own set of challenges. These shifts can unexpectedly disrupt campaign performance and ROI, making it crucial to understand the issues so you can address them before they drain your budget.
Unpredictable CPC, Impressions, and Conversion Rates
When bid algorithms change, key performance metrics like cost-per-click (CPC), impressions, and conversion rates can swing unpredictably. For instance, Smart Bidding algorithms might increase CPC based on predicted performance, but these predictions don’t always align with your business goals. This could mean high-performing campaigns lose budget while underperforming ones get more funding.
Take this into perspective: in 2023, the average CPC was $4.20 on Google Ads and about $0.80 on Facebook Ads. If an algorithm adjustment causes CPCs to spike, your budget could take a hit. Unlike automated systems, manual bidding reacts slower to market changes. Competitors’ bid shifts might also impact your rankings before you even realize it, leading to missed opportunities for traffic and conversions.
Data Delays and Mismatched Campaign Goals
Algorithm changes don’t just cause metric fluctuations - they can also disrupt data accuracy and misalign campaign goals. Delayed conversion data, for example, can force algorithms to rely on outdated information, which results in poor optimization.
Another pitfall is when campaign goals don’t match your business objectives. Let’s say your campaign is set to maximize clicks, but your real goal is to generate qualified leads. The algorithm might drive traffic, but it won’t necessarily be the kind that converts.
A case study highlights this issue: In May 2025, PPC Girlie increased her campaign budget in mid-March, initially seeing more conversions. However, by the end of the month, a conversion tracking issue caused significant spending without results. Even after pausing and restarting campaigns in April, conversions didn’t recover, and the cost-per-acquisition went up (Source: Google Ads Community, 2025). This example shows how tracking errors and delayed responses can snowball into bigger problems.
Sudden changes in user behavior also complicate things. Automated systems often continue spending based on historical data, but manual intervention is sometimes necessary to adapt to shifting market conditions.
Poor Conversion Tracking Problems
Faulty conversion tracking is one of the most expensive mistakes in PPC. Only 29% of Google Ads marketers have accurate conversion tracking in place. That means many advertisers are feeding unreliable data into their bid algorithms, which can lead to poor decisions.
Here’s how bad tracking can hurt your campaigns:
- Mixing different types of goals, like awareness metrics and lead generation, can confuse algorithms and lead to wasted budget.
- Failing to filter phone calls or missing offline conversion data can distort performance metrics, causing algorithms to overbid on low-value traffic.
- Inconsistent attribution models or improperly configured "Conversions" columns can send the wrong signals to the algorithm.
For example, setting call duration thresholds too low might count brief, unqualified calls as conversions. This skews your data, encouraging the algorithm to bid aggressively on traffic that doesn’t bring real value.
Data quality directly affects ad rank and overall performance. If your tracking signals are off, the algorithm might prioritize keywords that look good on paper but don’t generate meaningful results. Meanwhile, it could reduce spending on traffic that actually delivers profitable leads.
As Peter Drucker famously said:
"What gets measured, gets managed".
If your measurement system is flawed, automated bidding can end up working against you. Fixing these tracking issues is a must before you can move on to implementing better bidding strategies in the next section.
How to Fix Bid Algorithm Issues
If you're grappling with bid algorithm issues, don't worry - these problems can be addressed by fine-tuning your campaign setup and management. By focusing on accurate conversion tracking, selecting the right bidding strategies, and finding the right balance between automation and manual oversight, you can take back control of your ROI. Here's how to tackle these challenges effectively.
Setting Up Proper Conversion Tracking
Accurate conversion tracking is the backbone of effective automated bidding. Without reliable data, even the most advanced algorithms will falter, leading to wasted budgets and misaligned campaign goals. One of the first steps is to use native Google Ads conversion tracking instead of relying solely on imported data from GA4. This shift can boost conversion data accuracy by 10–20%. While GA4 imports are helpful for broader insights, native tracking provides the precise data algorithms need to perform better.
"Google's conversion tracking can break down your numbers and tell you where each conversion came from. It can even show you the journey your visitors took to find you. Most importantly, it shows you where the waste is." – Perry Marshall, Author of 80/20 Sales & Marketing & Ultimate Guide to Google Ads
To further improve tracking reliability, consider server-side tracking. This approach circumvents browser limitations and cookie restrictions, ensuring your data remains accurate even as privacy laws evolve.
Key steps for implementing robust tracking include:
- Defining primary and secondary conversions clearly. Focus primary conversions on key actions like purchases or leads, while secondary conversions provide insights into the customer journey but shouldn't influence bidding decisions.
- Choosing the right counting method. Use "Every" for transactions with repeat conversions and "One" for single-action leads.
- Testing your setup. Use Google Tag Manager's preview mode to ensure everything is functioning correctly before launching.
- Setting appropriate conversion windows. Align these with your sales cycle to avoid skewed data. For example, if conversions typically take two weeks, a 30-day window could confuse the algorithm.
Using Advanced Bidding Strategies
Once your conversion tracking is reliable, advanced bidding strategies can help you achieve your goals more effectively. The key is to align the strategy with your specific objectives and adjust as needed.
- Enhanced CPC (ECPC): This strategy blends manual and automated bidding by adjusting your manual bids based on signals like location, device, and time of day. It’s ideal for those transitioning from manual bidding or wanting partial control.
- Target CPA: If you're focused on controlling customer acquisition costs, Target CPA is a solid choice. It stabilizes costs even when CPC fluctuates. Start with realistic targets based on historical data to avoid limiting traffic.
- Target ROAS: For campaigns focused on revenue rather than conversions, this strategy adjusts bids to meet your desired return on ad spend. Gradually tweaking your targets - lowering for more volume or raising for higher-value conversions - can refine performance.
"With Target ROAS, you set a target return on ad spend, and Google adjusts bids to achieve that goal. This strategy works best when your campaign is focused on driving revenue rather than just conversions." – Ad Leverage
- Maximize Conversions: This strategy aims to get the most conversions within your budget. If you're using a maximize clicks strategy, be sure to set a maximum CPC limit to prevent overspending.
Your choice of strategy depends on your goals. Enhanced CPC offers partial automation, while Target CPA and Target ROAS are fully automated solutions tailored to customer acquisition or revenue generation.
Combining Automation with Manual Control
While automation can streamline processes, human oversight is essential for adapting to sudden changes. The best results come from blending automation with strategic manual input. Algorithms can miss important nuances, but manual control ensures you stay responsive.
"The balance between automation and human strategic oversight is the key to maximum efficiency." – Anna Saskevich, PPC Manager at Aimers
Here’s how to strike that balance:
- Set clear campaign goals. These objectives guide both the algorithm and your manual adjustments. When algorithm updates occur, clear goals help you assess whether the changes align with your business needs.
- Monitor campaigns regularly. Watch for warning signs like sudden CPC spikes, drops in traffic quality, or unusual conversion rates. Step in manually when performance veers off track.
- Adopt a hybrid approach. Let automation handle bid optimization while you manage targeting and audience settings. This ensures efficiency without sacrificing traffic quality.
- Experiment strategically. Use A/B testing to explore new tactics, especially during algorithm updates. Manual oversight is crucial for designing and interpreting these experiments.
"Automated bidding simplifies bid management, optimizes PPC performance, and helps advertisers scale efficiently. However, success depends on using the right strategy, setting realistic goals, and continuously monitoring results." – Neil Patel, Co-Founder of NP Digital & Owner of Ubersuggest

How to Measure ROI After Algorithm Changes
Making adjustments to your bids is just the beginning. To truly understand if these changes are paying off, you need to measure your ROI. Without proper measurement, it’s easy to misinterpret performance shifts and wrongly attribute them to your bid adjustments.
Key Metrics for ROI Measurement
There are several metrics you can use to gauge the effectiveness of your optimizations. Let’s break them down:
- Cost Per Acquisition (CPA): This metric shows how much you’re spending to acquire each customer. It’s a quick way to see if your adjustments are making your campaigns more efficient or driving up costs. The average CPA across industries is $48.96.
- Return on Ad Spend (ROAS): ROAS links your ad spend directly to revenue. A good benchmark is a 4:1 ratio, meaning you should earn $4 for every $1 spent. On average, ROAS tends to hover around 2:1, or $2 in revenue for every $1 spent on ads.
- Click-Through Rate (CTR) and Conversion Rate: These two metrics work together to give you a complete view of your campaign’s performance. The average PPC click-through rate is 3.17%, and the average Google Ads conversion rate is 3.75%. Monitoring these metrics helps you see if your campaigns are reaching the right audience and converting effectively.
- Quality Score: This metric affects both your ad rank and cost-per-click. It considers factors like expected CTR, ad relevance, landing page experience, and your bid during the auction. Changes in Quality Score can amplify - or diminish - the impact of your bid adjustments.
- Return on Investment (ROI): Unlike ROAS, ROI accounts for all costs, not just ad spend. It includes expenses like agency fees, software costs, and internal labor. A strong ROI is typically around 5:1, meaning $5 of profit for every $1 spent.
After gathering data on these metrics, compare them before and after your adjustments to isolate their impact on ROI.
Comparing Performance Before and After Changes
To accurately measure the effect of your algorithm changes, you’ll need to compare performance over clearly defined time periods. Ideally, analyze at least 30 days of data before and after the changes. This timeframe accounts for learning periods and seasonal trends. Tools like UTM tags can help track visitor data, including the source, medium, and campaign that brought them to your site.
Segment your data by factors like campaign, keyword, audience, device, or location. This helps pinpoint where your changes had the biggest impact.
Here’s an example of how to structure your performance comparison:
| Metric | Before Changes | After Changes | Percentage Change | Dollar Impact |
|---|---|---|---|---|
| Total Ad Spend | $10,000 | $9,500 | -5% | -$500 |
| Total Revenue | $25,000 | $28,500 | +14% | +$3,500 |
| ROAS | 2.5:1 | 3.0:1 | +20% | +$4,000 net gain |
| CPA | $45.45 | $38.00 | -16.4% | $7.45 savings per conversion |
For an accurate ROI calculation, include both direct and indirect costs. Direct costs are your ad spend, while indirect costs include management fees, software subscriptions, and labor.
Multi-touch attribution is another useful tool. Instead of crediting just one click for a conversion, this method allocates value across all customer interactions. Keep in mind that different attribution models - like last-click or first-click - can yield varying results.
Cohort analysis is particularly helpful for businesses with longer sales cycles or subscription models. It tracks revenue over time for specific customer groups, offering insights like time to profitability and short-term vs. long-term ROI.
"Each platform will use slightly different metrics or calculate them in different ways. For example, a Purchase in Meta is different than a Conversion in Google Ads."
– Tim Akers, Founder, Akers Digital
A/B testing can also help isolate the impact of your bid changes. Run campaigns with different bidding strategies simultaneously and compare the results. Be sure to account for external factors like seasonality, ad fatigue, and competition when analyzing your data.
For example, Aeropost worked with scandiweb to refine its bidding strategies. By focusing on maximizing conversion value and targeting ROAS for marketplace accounts, they achieved a 31.44% uplift in ROAS and a 144.61% increase in revenue year-over-year.
When reporting results, prioritize actionable metrics like CTR, CPC, conversion rates, and ROAS over vanity metrics that don’t contribute to business goals.
"Vanity metrics are those stats that you like to show off to make the efforts you're making look good for you, but in the end, really don't mean anything, especially towards the end business goals you really want to achieve."
– Nathan Hawkes, President, Arcane Marketing
