1. Fixate on ROAS Without Understanding Its Drivers
ROAS (return on ad spend) is the ultimate PPC metric. It separates the campaign winners from the losers.
Understanding ROAS is crucial, but overlooking other important Google Ads metrics to track like CTR, CPC, and conversion rates can lead to skewed insights.
But many marketers get so focused on that final ROAS number, they forget about the four key factors behind it:
| Factor | Description | Impact on ROAS |
|---|---|---|
| Click-Through Rate (CTR) | Percentage of people clicking your ad after seeing it. | Higher CTR increases the likelihood of conversions. |
| Cost Per Click (CPC) | Amount paid for each click on your ad. | Lower CPC reduces ad spend and boosts ROAS. |
| Conversion Rate (CVR) | Percentage of visitors completing a desired action. | Higher CVR increases overall revenue per click. |
| Average Order Value (AOV) | The average revenue from a single order. | Higher AOV significantly boosts total ROAS. |
ROAS is directly influenced by these four factors. So if your ROAS is underperforming, it’s because one (or more) of these components is holding it back.
It’s also crucial to have a compelling offer and strong product-market fit. A poor offer can’t be salvaged by bid management alone. Provide clear and comprehensive information on your landing pages to reduce friction and increase conversions.
Q: How can I troubleshoot a sudden drop in ROAS?
A: If your ROAS takes a nosedive, start by examining each of the four underlying metrics – CTR, CPC, CVR, and AOV. Look for any significant changes that coincide with the ROAS decline.
For example, if you notice your CTR has plummeted, it could signal your ad copy or keyword targeting needs refreshing. If your CPC has spiked, competitor activity or shifts in the auction could be to blame.
Isolate the root cause to take swift, targeted action to course-correct your ROAS.
2. Make Decisions Based on Insufficient Data
Scenario: you launch a promising new ad group. You wait on the edge of your seat, ready for a flood of conversions. But after a few days…silence. Tumbleweeds. Nothing.
Panic sets in. You start adjusting bids, rewriting ad copy, and swapping keywords to see what works.
We’ve all been there. But here’s the issue: making significant changes based on a small amount of data is a surefire way to undermine your results.
Three reasons why:
- Small sample volatility. A few days (or even weeks) of data is rarely enough to draw reliable conclusions. Effective PPC tracking verifies that data collection is accurate and sufficient, helping to avoid premature or misguided decisions. Decisions based on limited data are prone to inconsistencies.
- Learning phase reset. Every major change to an ad group sends the campaign back to square one of the learning phase. This can trap you in an endless cycle where the algorithms never gather enough data to optimize.
- Misattribution. Changing multiple variables simultaneously makes it impossible to identify what’s actually working (or not). You end up chasing symptoms instead of addressing root causes.
It’s also crucial to set realistic growth goals aligned with your ad investment, consumer demand, and past performance. To make tracking progress easier, use a Google Ads report template to consolidate key metrics and share clear insights with your team or clients. Unrealistic expectations can lead to hasty decisions based on insufficient data.
Another frequently overlooked area is analyzing performance by geo-location. Many advertisers fail to examine country, regional or even zip code level data to identify top and bottom performers. Adjusting bids or exclusions based on geographic insights can have a significant impact on efficiency.
3. Fight Negative Keywords One by One
Negative keywords are the heroes of PPC. These invisible workhorses protect your budget from irrelevant searches and help your ads reach high-value queries.
But many marketers play an endless game of negative keyword whack-a-mole, adding negative terms as they pop up.
The problem? It’s reactive instead of proactive. The time you identify a bad keyword, it’s already wasted precious ad spend. Plugging individual leaks doesn’t address the underlying issue.
Q: What’s the most efficient way to discover new negative keywords?
A: Poring over your search terms report is a good start, but it can be tedious and time-consuming. Here are three ways to supercharge your negative keyword mining:
- Use Google’s built-in search terms report filter to automatically identify searches that meet specific criteria (e.g. high spend but no conversions).
- Leverage the power of Excel or Google Sheets. Export your search terms report, then use conditional formatting, pivot tables, and filters to surface trends and outliers.
- Try third-party tools like Optmyzr or n-gram analysis to automate the negative keyword discovery process at scale.
The goal is to shift from reactive defense to proactive offense.
4. Neglect Emotional Appeal in Ad Copy
Reality check: your customers aren’t robots. They’re complex, emotional beings driven by desires, fears, and motivations. But most PPC ads sound like they were written by an algorithm – generic, flat, and uninspiring.
Want to stand out in the search results and get clicks? Put yourself in your target audience’s shoes and tap into the right psychological triggers.
Three tactics to try:
- Appeal to their desires. What do your prospects want most? Respect? Independence? More free time? Weave those hooks into your headlines.
- Agitate pain points. What problems keep your audience up at night? Wasting money? Losing time? Feeling insecure? Highlight those issues in your copy.
- Leverage social proof. Humans are social creatures. We look to others for guidance. Showcase impressive clients, numbers, or testimonials to boost credibility.
The magic happens when you blend those emotional elements with relevant keywords and offers. You want your ads to strike an emotional chord and convince Google you’re a perfect match for the search query.
Q: How do I write emotionally compelling ad copy at scale?
A: Injecting emotion into your ads can feel like an art, but there’s a science to it too. Use these repeatable steps to craft emotionally potent ads at scale:
- Research your audience. Dive deep into your buyer personas, mine customer reviews, and interview your sales team to uncover the key emotions that drive your target market.
- Identify high-impact words. Build a master list of emotionally charged words and phrases that resonate with your audience. Sprinkle them strategically throughout your ad copy.
- Templatize your ad structure. Create a basic ad template that includes placeholders for your target keyword, emotional hook, unique selling proposition, and call to action. Use this blueprint to efficiently generate ads at scale.
- Split test. A/B test different emotional angles and word choices to pinpoint the most impactful messaging for each ad group.
5. Overlook YouTube and Gmail Ads
Quick question: when you think of “Google Ads,” what comes to mind first? I’d wager it’s search ads, followed by display.
But here’s the twist: Google’s advertising options extend far beyond the Search Network. PPC professionals who focus solely on search and display are missing out on a goldmine.
Enter the hidden gems of YouTube and Gmail ads.
These underutilized channels boast cost-effective CPMs, precise targeting, and massive engaged audiences.
YouTube ads and Gmail ads enable you to:
| YouTube Ads | Gmail Ads |
|---|---|
| Reach over 2 billion logged-in users each month | Place interactive ads directly in your audience’s inboxes |
| Tap into Google’s vast repository of intent and interest data to reach your ideal audience | Secure low CPMs of just $2 – $5, a bargain compared to search and display |
| Access video views for as little as $0.10 – $0.30 each | Promote launches, content, events to carefully selected audiences |
| Build full-funnel campaigns to drive awareness, consideration, and action | Combine affinity targeting with your customer email lists for unparalleled relevance |
The best part? Competition is still relatively low on these networks – meaning early adopters can see significant results without huge investments.
Q: How do I get started with YouTube ads?
A: YouTube ads can be daunting if you’ve never run them before. Here’s a quick-start guide:
- Set your goals. Are you looking to build brand awareness, drive site traffic, or generate leads? Your objectives will dictate your ad formats and targeting.
- Know your ad types. YouTube offers three main ad formats: skippable in-stream ads (the most common), non-skippable in-stream ads (best for reach), and discovery ads (appear in YouTube search results).
- Define your audience. Use YouTube’s robust targeting options to zero in on your ideal customers. Leverage life events, affinities, purchase intent, and more.
- Create compelling videos. Your video ad is the star of the show. Keep it short, attention-grabbing, and emotionally resonant. Include a clear call to action.
- Set your bids and budget. Start with a modest daily budget and use Target CPA bidding to optimize for conversions. Monitor your performance closely and adjust as needed.
6. Disregard Quality Score Until It’s Too Late
Quality Score is Google’s way of rating your ads’ relevance and usefulness to searchers. The higher your Quality Score, the more favorably Google views your ads. That translates to better ad positions, higher click-through rates, and lower costs.
But too many agencies treat Quality Score as an afterthought. They’re content to let it languish while chasing flashier metrics. Focusing solely on click costs (CPCs) without considering other important metrics like conversion rates and quality scores can be detrimental to your campaigns.
Big mistake. Neglecting Quality Score can lead to:
- Escalating CPCs that strain your budget
- Plummeting ad positions that undermine your click-through rates
- Declining ROAS that hurts your bottom line and client relationships
