1. Google Business ranking algorithm and the importance of reviews
Reviews are one of the three main factors for local SEO success ("proximity, prominence, relevance") according to Google's own official documentation:
Google: Improve your local ranking on Google
"Google review count and review score factor into local search ranking. More reviews and positive ratings can improve your business's local ranking."
Translation: “The number of reviews and average rating affect local search ranking. More reviews and positive ratings can improve your business’s local ranking.”
So, every negative review (especially if it cannot be denied or countered) has a direct impact on your positions on Google Maps and in local search - that is, on the actual flow of visitors.

2. Unethical or biased reviews – a violation of the rules
Google makes it clear that vindictive, repetitive, or inauthentic reviews violate the platform's policies. This is especially true when a former employee leaves multiple reviews from different accounts:
Google Maps Contributor Policies
"Don't post fake content, post the same content multiple times, or post content for the same place from multiple accounts."
Such reviews are considered manipulative and can be removed. However, until this is done, they affect the algorithm's decisions and damage the business's reputation.

3. User reactions strengthen the weight of reviews
If a negative review receives reactions ("❤️", "Thank you", etc.), it is considered more useful to other users, which increases its visibility. This has been unofficially confirmed in the SEO professional community:
BrightLocal - What Makes a Google Review Helpful?
Reviews that receive reactions are more likely to be promoted to the top and gain more importance in the eyes of Google.

4. The impact of reputation on advertising costs
As organic visibility declines, businesses are forced to rely on Google Ads to maintain traffic and conversions. This means increased budgets, decreased ROAS (return on ad spend), and an overall decline in marketing effectiveness.
Search Engine Journal - Why Your Google Reviews Matter for PPC
"Poor online reviews can drastically reduce click-through rates (CTR), quality scores, and overall campaign efficiency in Google Ads."
In short: the worse the reputation, the more expensive the advertising and the lower the return.

5. Business reputation and trust factor
Potential customers rely on Google Business Profile reviews as a primary source of trust, with research showing that 93% of consumers base their decision on reviews.
Exploding Topics - Online Review Statistics
"4 in 5 consumers say they've changed their mind about a purchase after reading negative online reviews."
Therefore, biased, destructive reviews have long-term commercial impacts: reduced customer trust, lost sales, and lower conversion.
⸻
Conclusion
Negative, biased, or vindictive reviews on your Google Business Profile:
• reduces organic visibility and ranking;
• undermines consumer confidence;
• causes additional advertising costs;
• may violate Google policies and be grounds for removal.
⸻
Summary
Negative, biased, or repetitive reviews on Google Business Profile have a direct negative impact on a business's ranking, organic visibility, and can significantly increase the need for advertising budget. Such reviews distort the true user experience, reduce trust in the business, and hinder conversions.
