Last year we took over a Google Ads account for a B2B SaaS company that was paying $340 per lead. Within 90 days, we had that down to $142. No magic, no secret hack. Just systematic work on the things that actually move the needle.
If your CPA is higher than you’d like — and let’s be honest, it almost always is — here are the ten things we look at first. These aren’t theoretical. They come from managing millions in Google Ads spend across B2B, ecommerce, edtech, and real estate.
1. Audit Your Search Terms Report (Weekly, Not Monthly)
This is the single highest-ROI activity in any Google Ads account, and most teams do it way too infrequently.
Go to Insights & Reports > Search Terms. This shows you the actual queries people typed before clicking your ad. You will find garbage. I promise. Every account we’ve ever audited has search terms that have nothing to do with the business, and those terms are eating budget.
A B2B company selling enterprise security software? Their ads were showing for “free antivirus download.” An ecommerce brand selling premium dog food? Clicks from people searching “dog food recipes at home.”
Add negative keywords aggressively. Do this every week. Set a calendar reminder. The amount of wasted spend hiding in search terms is almost always shocking on the first pass.
2. Stop Sending Traffic to Your Homepage
I can’t stress this enough. Your homepage is designed to serve everyone — returning customers, investors, job applicants, journalists. It’s not designed to convert someone who just searched “B2B lead generation software pricing.”
Build dedicated landing pages for your top campaigns. The landing page should match the search intent exactly. If someone searches “CRM for real estate agents,” the landing page headline should be about CRM for real estate agents. Not “Welcome to our website.”
We’ve seen CPA drop 30-50% just from this one change. It’s not glamorous work, but it’s the highest-leverage thing you can do after cleaning up search terms.
3. Fix Your Conversion Tracking Before Optimizing Anything
Here’s a scenario I see constantly: a team is optimizing toward a goal, but the conversion tracking is misconfigured. Maybe they’re counting page views as conversions. Maybe the tag fires twice on the thank-you page. Maybe they’re tracking newsletter signups with the same weight as demo requests.
If your data is wrong, your optimizations are wrong. Before you tweak bids or test new ad copy, verify that:
- Your conversion actions in Google Ads match actual business outcomes (not just form submissions if half of those are spam)
- Each conversion action fires exactly once per real conversion
- You’ve assigned appropriate values if you’re using value-based bidding
- Your GA4 and Google Ads conversion data roughly agree with each other
Spend an hour auditing this. It’s boring. It’s also the foundation everything else rests on.
4. Use Exact Match and Phrase Match Strategically
Broad match has gotten better with Google’s machine learning improvements, but it still casts a wide net. For accounts where budget is tight or CPA needs to come down, shifting spend toward exact match and phrase match keywords gives you more control over what triggers your ads.
The tradeoff is volume. Exact match will get you fewer impressions but higher intent clicks. Our typical approach is:
- Exact match for your highest-value, proven keywords
- Phrase match for variations and longer-tail queries you want to capture
- Broad match only in campaigns with enough conversion data (50+ conversions per month) for Google’s algorithm to optimize effectively
If you’re spending under $10K/month, broad match is probably costing you more than it’s giving you.
5. Dayparting: Stop Paying for Clicks at 3 AM
Look at your conversion data by hour of day and day of week. Most B2B accounts see nearly zero conversions between midnight and 6 AM, and often on weekends too. But the clicks keep coming — bots, random browsers, people who will never become customers.
Set an ad schedule that concentrates budget during your highest-converting hours. For B2B, that’s usually Tuesday through Thursday, 8 AM to 6 PM in your target time zones. For ecommerce, it varies more, but there’s almost always a pattern.
You can also use bid adjustments instead of fully pausing. Reduce bids by 50-80% during low-conversion hours rather than shutting them off completely. This way you don’t miss the occasional off-hours conversion while still protecting your budget.
6. Bid Strategy Alignment
This trips people up because Google makes it sound simple. “Just use Maximize Conversions!” But the right bid strategy depends on your specific situation.
Target CPA works best when you have at least 30-50 conversions per month and a clear CPA target. Set it 10-15% above your actual target initially and tighten it over time as the algorithm learns.
Target ROAS makes sense for ecommerce with variable order values. You need conversion value tracking set up correctly.
Maximize Conversions without a target CPA will spend your entire budget as fast as possible. Sometimes that’s fine for data gathering. Usually it results in a CPA spike.
Manual CPC gives you the most control but requires constant attention. We use it for new campaigns where we don’t trust the algorithm yet or for very low-volume accounts.
The mistake I see most often: switching bid strategies too frequently. Every time you change, the algorithm re-enters a learning period and performance dips. Pick a strategy, give it 2-3 weeks, and evaluate. Don’t panic-switch after three days of high CPA.
7. Ad Copy That Pre-Qualifies
Your ad copy should attract the right people and repel the wrong ones. This sounds obvious, but most ads try so hard to get clicks that they attract everyone, including people who will never buy.
If you sell enterprise software starting at $500/month, put a price indicator in your ad. “Plans from $500/mo” will scare off the people looking for a free tool. Good. Those clicks would have cost you money and produced nothing.
Other pre-qualifying tactics:
- Mention your target audience explicitly: “For B2B SaaS Companies” or “Built for Ecommerce Brands”
- Include qualifiers: “For Teams of 50+” or “Enterprise-Grade”
- Use your unique selling point as a filter: “White-Glove Onboarding Included” signals a premium service
Higher CTR is not always better if the clicks aren’t qualified. A slightly lower CTR with much higher conversion rate will always produce a better CPA.
8. Geographic Bid Adjustments
If you serve multiple markets, don’t treat them all equally. Pull a geographic report and look at CPA by state, city, or country. The differences can be massive.
We had a client spending equally across all 50 US states. Their CPA in California was $89. Their CPA in several rural states was $400+, driven by low search volume and poor intent matches. By reducing bids in the worst-performing geographies and increasing bids in the best, CPA dropped 22% with the same budget.
For international campaigns, this is even more pronounced. Some countries convert at 3x the rate of others for the same product.
9. Landing Page Speed Matters More Than You Think
Google’s own data shows that a page load time increase from 1 second to 3 seconds increases bounce rate by 32%. From 1 to 5 seconds, bounce rate goes up 90%.
You’re paying for every click. If 30% of those people bounce because your landing page takes 4 seconds to load, you’re burning almost a third of your budget on people who never even saw your content.
Check your landing page speed in Google PageSpeed Insights. The common culprits:
- Oversized images (compress them, use WebP format)
- Too many scripts loading before the page renders
- No browser caching
- Cheap hosting that can’t handle traffic spikes
For our clients, we aim for a load time under 2 seconds on mobile. The impact on CPA is real and measurable.
10. Remarket Smarter, Not Harder
Most remarketing campaigns are lazy. They show the same generic ad to everyone who visited the website, regardless of what they did there. That’s a missed opportunity.
Segment your remarketing audiences:
- Cart abandoners get ads about the specific products they left behind, maybe with a small incentive
- Pricing page visitors get ads that address common objections (“No long-term contracts” or “Free migration included”)
- Blog readers get softer ads pushing a relevant lead magnet, not a hard sell
- Past converters get cross-sell or upsell ads, not the same acquisition message
Also, set frequency caps. Showing someone the same ad 47 times in a week doesn’t make them more likely to convert. It makes them annoyed. 3-5 impressions per user per day is a reasonable cap for most campaigns.
The Compounding Effect
None of these changes in isolation will transform your account overnight. But they compound. Fix your tracking, clean up search terms, build proper landing pages, align your bid strategy, pre-qualify with ad copy, and optimize geographies and schedules — stack all of that together and a 40-60% CPA reduction is realistic within 60-90 days.
The key is consistency. Google Ads is not a “set it and forget it” channel. The accounts that perform best are the ones that get attention every single week.
