What one improvement can have the biggest impact on a Google Ads account?
It sounds like a simple question.
Change the bidding strategy?
Improve the keywords?
Increase the budget?
Fix the landing page?
Use Target CPA?
The problem is that Google Ads rarely works that way.
After managing and reviewing campaigns across different clients, industries, geographic markets and business models, our experience at AARSWEBS has shown us that the improvement producing the biggest result in one account may do almost nothing in another.
Sometimes the biggest opportunity is inside Google Ads.
Sometimes it is the conversion tracking.
Sometimes it is the landing page.
And sometimes the Google Ads campaign is doing its job perfectly well—but the offer simply is not competitive enough.
That is why effective Google Ads optimization starts with diagnosis rather than copying another advertiser’s settings.
A Viewer Reported a 22% Improvement From Portfolio Bidding
This topic came from a question submitted to Ali Raza’s YouTube channel.
The advertiser was managing a large account with approximately 20 local campaigns.
After implementing portfolio bid strategies and separating campaigns according to different CPA targets, the advertiser reported approximately a 22% month-over-month improvement in conversions.
Naturally, the question was:
Is this the one improvement that has the biggest impact on a Google Ads account?
It certainly can be a major improvement.
But it is not automatically the answer for every account.
A bidding strategy works inside the environment you give it.
That environment includes your conversion data, keywords, locations, ads, budget, landing pages, offer and customer behaviour.
If one of those areas is the actual bottleneck, changing the bid strategy alone may not solve the real problem.
1. Conversion Tracking May Be Your Biggest Improvement
One of the first areas we inspect when auditing an account is conversion tracking.
Why?
Because advertisers often make decisions based on what Google Ads reports as a conversion.
If important actions are missing, duplicated or incorrectly configured, you may be judging campaigns using incomplete information.
For a lead-generation business, important actions could include:
- Qualified phone calls
- Contact-form submissions
- Appointment bookings
- WhatsApp enquiries
- Quote requests
- Completed purchases
- High-value lead events
Imagine two campaigns.
Campaign A generates 20 clicks and three qualified customers.
Campaign B generates 20 clicks and eight button presses that never become genuine enquiries.
If the account is measuring the wrong events, Campaign B can appear stronger even though Campaign A is producing the real business result.
Before aggressively changing bidding, ask:
Are we accurately measuring the action that actually matters to the business?
For some accounts, fixing this alone is the most important improvement.

2. Your Bidding Strategy Can Be the Main Growth Lever
For another advertiser, the conversion data may already be reliable.
In that situation, bidding can become the larger opportunity.
Depending on the account and objective, advertisers may experiment with strategies focused on:
- Conversions
- Target CPA
- Conversion value
- Target ROAS
- Click volume
- Portfolio-level objectives
The advertiser who asked this question saw strong results after grouping campaigns according to CPA expectations and using portfolio bidding.
That worked for their particular account.
But the important lesson is not:
“Everybody should copy this bidding strategy.”
The useful lesson is:
“The account had a bidding structure that could be improved, and fixing that structure produced a measurable result.”
There is a big difference.
Your bidding strategy should support your business objective—not become the objective itself.
3. Being in Position #1 Is Not Always the Best Business Decision
Advertisers naturally want the number-one position.
It feels better.
It looks more dominant.
Clients sometimes ask why their advertisement is not appearing above every competitor.
But advertising is not a ranking competition.
It is a profitability exercise.
We have seen situations where competing aggressively for the absolute top position increased costs without producing a proportional improvement in sales.
In one case discussed by Ali, the second position appeared to generate very good sales.
Why?
There can be many reasons.
Perhaps the users who clicked later were more qualified.
Perhaps the economics of the click were better.
Perhaps the competitor in first position paid significantly more for traffic without gaining enough additional conversion value.
The lesson is not that second position is always better.
It is that you should evaluate the business outcome instead of chasing position for ego.
4. Location Targeting Can Completely Change Results
Geography can be one of the most overlooked Google Ads optimization opportunities.
Two areas in the same city can produce completely different economics.
One location may generate:
- Higher-value customers
- Better lead quality
- Shorter travel distances
- Higher close rates
- Lower cost per acquisition
Another may consume budget while producing poor enquiries.
This becomes particularly important for:
- Local service businesses
- Contractors
- Clinics
- Lawyers
- Home-service companies
- Restaurants
- Automotive services
- Businesses with defined service areas
Instead of treating every location equally, review performance at the geographic level.
Sometimes the biggest improvement is not a new campaign.
It is simply spending more in the areas that already produce better customers and reducing exposure where the economics do not work.
5. Day and Time Can Become a Major Optimization Lever
Another account may perform differently depending on the day of the week or hour of the day.
We have worked with businesses where weekends were especially important.
Another advertiser may perform better during business hours.
Others may receive strong traffic at night but very few qualified enquiries.
There is no universal scheduling rule.
The important question is:
When are your best customers actually converting?
Look beyond clicks.
Compare:
- Conversion rate
- Lead quality
- Cost per lead
- Sales
- Revenue
- Close rate
If Saturday traffic consistently produces better customers, weekend coverage may deserve more attention.
If late-night clicks generate almost no commercial value, the strategy may need to change.
The account data should guide the decision.
6. Your Landing Page Can Be More Important Than Your Google Ads Settings
You can build an excellent Google Ads campaign and still produce disappointing sales.
Why?
Because the advertisement only gets the visitor to the website.
The landing page has to continue the sale.
A strong Google Ads landing page should quickly answer questions such as:
- Am I in the right place?
- Does this company provide the service I need?
- Why should I choose this business?
- Can I trust them?
- What will happen after I enquire?
- How do I contact them?
- What is the offer?
Landing-page friction can include:
- Slow loading
- Weak mobile usability
- Confusing navigation
- Poor message match
- No obvious call to action
- Weak trust signals
- An unnecessarily long form
- Poor presentation of the offer
If your ads are attracting relevant prospects but very few are becoming leads or customers, the biggest Google Ads improvement may actually happen outside Google Ads.
7. Your Offer Can Beat—or Destroy—an Excellent Campaign
This is one of the most important points.
You could have:
- A professional company
- Good advertising
- Relevant keywords
- Excellent tracking
- A fast landing page
- Strong bidding
And still lose the customer.
Why?
Because your competitor has a better offer.
Suppose your competitor gives the customer:
- Faster delivery
- A stronger guarantee
- Better financing
- Free consultation
- More transparent pricing
- A useful bonus
- Better availability
- More convincing proof
The customer does not care that your Google Ads account is technically perfect.
They care about what they receive.
Advertising brings the customer to the decision.
The offer influences which decision they make.
This is why offer analysis should be part of Google Ads optimization.
So Which Google Ads Improvement Should You Make First?
Start with the bottleneck.
Here is a practical diagnostic framework.
| What you are seeing | What I would inspect first |
|---|---|
| Google Ads shows few or no conversions | Conversion tracking |
| Traffic is coming but leads are poor | Search intent, keywords, locations and offer |
| Leads are relevant but CPA is too high | Bidding, search terms, landing page and competition |
| One region performs much better | Geographic targeting and budget allocation |
| Weekends outperform weekdays | Ad scheduling and staffing |
| High positions are expensive | CPA and profitability by auction/position signals |
| Good traffic but poor conversion rate | Landing page and offer |
| Performance changes after bid adjustments | Bidding strategy, targets and conversion data |
| Strong lead volume but poor sales | Lead quality, sales process and offer |
These are starting points—not guaranteed diagnoses.
The job of a professional audit is to identify which part of the system is actually limiting performance.
The Biggest Google Ads Mistake: Optimizing the Wrong Problem
This is where many advertisers lose money.
They hear that Target CPA worked for somebody else, so they change to Target CPA.
They hear Performance Max worked for a competitor, so they launch Performance Max.
They hear broad match is producing scale for another agency, so they replace their keywords.
They hear the number-one position gets more clicks, so they bid more aggressively.
But what if none of those things is your real problem?
You could spend weeks optimizing something that was never the bottleneck.
A better process is:
1. Measure
Confirm that the account is measuring the business actions that matter.
2. Diagnose
Identify where performance is breaking down.
3. Segment
Review performance by campaign, keyword, search term, device, geography, time, landing page and conversion type.
4. Prioritize
Start with the problem that is likely having the largest commercial impact.
5. Test
Make a controlled improvement.
6. Validate
Compare the result using meaningful business metrics.
7. Scale
Only expand after the improvement has proven itself.
That process is less exciting than searching for a secret Google Ads setting.
But it is usually much more useful.
Google Ads Is a System, Not One Setting
The best campaigns usually work because several important components support each other:
Tracking → targeting → ads → bidding → landing page → offer → sales process
Weakness in one part can affect the entire result.
That is why there is no hard-and-fast answer to:
“What one improvement has the biggest impact on Google Ads?”
The answer depends on the account.
For one advertiser it could be conversion tracking.
For another, CPA-focused bidding.
For another, geographic targeting.
For another, weekends.
For another, the landing page.
And for another, the biggest improvement may have nothing to do with Google Ads at all.
It may simply be creating an offer customers prefer.
