Google Ads Optimization Score and automated suggestions are not designed to increase your company's profit, but rather to boost Google's ad revenue and auction volume. Blindly chasing a 100% score and enabling Auto-Apply features often destroys precise keyword targeting, unnecessarily expands campaigns into low-quality Display networks, and uncontrollably inflates your cost-per-acquisition. In this article, we conduct an in-depth audit of the 6 most dangerous Google Ads suggestions that must be dismissed, and provide a step-by-step protection protocol to maintain campaign profitability.
The true nature of the Google Ads Optimization Score
When performing independent Google Ads campaign management and opening an account, the system insistently urges you to pay attention to the Optimization Score, showing a percentage (e.g., 74.2%) and offering to 'improve' your account to 100% with a single click. Many business owners and inexperienced marketing specialists view this metric as a health check for their campaigns and blindly accept all suggestions.
The truth is much more pragmatic: Google is a publicly traded company whose primary source of profit is ad auctions. The algorithm's automated suggestions are designed to maximize auction inventory, increase click volume, and ensure that businesses spend their entire daily budget. This does not mean automation is inherently bad, but it does mean that every suggestion must be evaluated through the lens of company profit, not Google's revenue.
Below, we have compiled the TOP 6 most dangerous Google Ads suggestions that, in 80% of cases, must be dismissed to maintain control over your money and achieve true profitability. Strategic digital advertising requires constant human oversight and control over campaign budgets, which cannot be blindly entrusted to automated suggestions.
"The Google Ads Optimization Score is not built to increase your company's profit, but to maximize Google's ad revenue. By striving for a 100% score and automatically accepting all suggestions, businesses waste thousands of euros every month."
TOP 6 automated suggestions that burn your budget
1. Switching to Broad Match for all keywords
This is Google's most frequently pushed suggestion. The system claims that by replacing Exact Match and Phrase Match keywords with Broad Match, you will get more conversions for similar costs. In reality, for small and medium-sized businesses with a budget under 3,000 euros per month, Broad Match often spells disaster: the algorithm starts showing ads for topics only tangentially related to your service, wasting money on useless searches.
2. Expanding Search to the Display Network
When you create a search campaign, Google offers to 'reach additional customers on the Google Display Network with one click.' By agreeing to this, your search ads are converted into small banner ads across thousands of random websites and mobile apps. Most of these clicks are accidental touches by children in mobile games, which do not bring in any real leads.
3. Increasing daily budgets due to 'limited budget' status
The recommendations panel regularly shows a warning: 'Your campaign is limited by budget. Increase your budget from 30 € to 85 € per day to get more clicks.' If the campaign is not currently optimized and its cost-per-acquisition (CPA) is too high, increasing the budget will only accelerate losses. The budget should ONLY be increased when the existing lead generation mechanism is working with stable profitability.
4. Switching to Target CPA or Target ROAS without sufficient data
Smart Bidding is a great tool, but it requires sufficient data volume. Google often suggests enabling Target CPA for campaigns that have had only 5 or 8 conversions in the last 30 days. Without at least 30 to 50 conversions per month, the machine learning model gets 'confused,' reduces impressions, and the campaign simply stalls. Before activating any smart algorithms, you must ensure flawless Google Analytics 4 and GTM conversion tracking so the system receives clean data.
5. Enabling Automatically Created Assets
Google offers to let the algorithm scan your website and generate new ad headlines and descriptions without your consent. Very often, these automatic texts are awkward, contain grammatical errors, or promise things the company does not actually offer. Creative materials must always be under human supervision.
6. Removing 'redundant' keywords
Google suggests deleting keywords it considers duplicates. However, in practice, these specific Exact Match keywords often provide the highest conversion rate at the lowest price. By deleting them, traffic shifts to broader terms with a higher cost-per-click.
Technical comparison: Google automation vs. Human control
| Feature | Google Default Automation | Strategic Control and Audit |
|---|---|---|
| Keyword match | Converting all keywords to Broad Match | Focused Exact and Phrase match with strict negative keywords |
| Network selection | Search combined with Display Network | Pure search, excluding Display and unwanted partners |
| Ad copy | Algorithmically generated headlines | Carefully vetted, brand-compliant text |
| Budget management | Constant pressure to increase daily limits | Budget scaling only upon confirmed profitability |
| Auto-Apply mode | Enabled (Google makes arbitrary changes) | Fully disabled; all changes are approved manually |
How to fully disable the dangerous Auto-Apply feature
One of the trickiest Google Ads features is Auto-Apply. If activated, the system arbitrarily implements the aforementioned changes in your account without warning. To stop this, follow these steps:
- In the left-hand Google Ads menu, click on Recommendations.
- In the top right corner of the screen, click the Auto-apply icon.
- Carefully check both tabs: Maintain your ads and Grow your business.
- Uncheck all boxes, especially those related to keyword expansion, budget changes, and text generation.
- Click Save. Now your account is safe, and no changes will be made without your knowledge. Read more about campaign fatigue and data control in our study on campaign fatigue and data erosion signals.
Why agencies often follow Google's suggestions and how to protect yourself
Business owners are often surprised to learn that their hired agency has enabled the very suggestions that burn their budget. The reason is simple: Google Premier Partner status requires agencies to maintain a high average Optimization Score across all managed accounts (at least 70% or higher).
As a result, agency employees are motivated to accept suggestions to keep the agency's certification and receive Google incentives, even if it directly worsens the client's campaign results. To avoid this, your contract with a marketing partner should clearly state: all structural campaign changes, keyword match types, and budget adjustments must be made only with prior approval and justification.
Centralized management of negative keyword lists
The most effective antidote to Google's desire to attract low-quality clicks is a strong Account-Level Negative Keyword List. Before launching any campaign, you should add at least 200 to 500 industry-standard negative keywords to the account: 'free', 'vacancies', 'jobs', 'courses', 'thesis', 'forum', 'reviews', and similar search phrases that indicate non-commercial interest.
Why Performance Max cannibalizes search campaigns
Google Performance Max (PMax) campaigns have become one of the most controversial tools in digital marketing. If a standard Search campaign and PMax are running simultaneously in an account, the algorithm defaults to prioritizing PMax, diverting search queries to generative ads with a higher cost-per-click.
To prevent this, you must implement a Brand Exclusion List and strict keyword prioritization in your account. If your Search campaign has an Exact Match keyword, Google is forced to show that specific ad, maintaining lower costs and better relevance to the landing page.
The regular 14-day 'Dismiss' protocol
To keep your Google Ads account highly efficient without unnecessary interference, we recommend implementing a 14-day recommendation audit routine:
- Every two weeks, open the Recommendations section.
- Review new suggestions: if they include valid negative keywords or technical warnings about broken links, accept them individually.
- For all other suggestions (budget increases, Broad Match implementation, Display expansion), click the three dots and select 'Dismiss all'.
This simple 2-minute process clears your account overview, raises your Optimization Score to 100%, and guarantees that your marketing strategy is driven by your business goals, not automated revenue algorithms.
Search Terms Report audit
While Google's automated suggestions invite you to trust the 'black box,' the most valuable data source in your account remains the Search Terms Report. This shows the actual words and phrases people typed into the search engine before clicking on your ad.
A weekly search term audit allows you to spot unwanted trends at the root and immediately add new negative keywords before they waste hundreds of euros. This human-led analytics ensures your advertising budget is invested only in attracting high-value buyers.
Historical performance comparison window: Before rejecting or accepting any suggestion, it is recommended to compare campaign data with the corresponding period from the previous year. Seasonal spikes are often mistakenly interpreted as 'algorithmic success,' even though demand would have increased without additional costs. Data comparison protects you from drawing incorrect conclusions.

Frequently Asked Questions about Google Ads suggestions
Does a low Optimization Score lower my ad Quality Score?
No, these are two completely unrelated metrics. Google has clearly stated in its official documentation that the Optimization Score does not in any way affect your ad Quality Score, Ad Rank, or cost-per-click. You can reject all suggestions and maintain a perfect 10/10 Quality Score for your keywords.
What happens if I click 'Dismiss' on all suggestions?
By dismissing unwanted suggestions, your Optimization Score automatically rises to 100%! This proves that this metric is merely an administrative reminder list, not a technical quality assessment. Simply reject what is not profitable for your business.
In what cases are Broad Match keywords actually useful?
Broad Match can be a very powerful tool ONLY if the account has accumulated a massive conversion history (at least 100+ conversions per month), has Smart Bidding enabled, and has a massive, regularly updated negative keyword list. Without these prerequisites, Broad Match will always cost more.
