The rules of the search game have changed. While people used to fight for the TOP 10 in Google and Yandex, the battle is now over getting into a single ChatGPT response.
Users "google" less and less, instead asking AI more often: "Recommend the best email service" or "Which vacuum cleaner should I buy in 2025?". If the neural network doesn't mention your brand, you lose customers without even knowing it.
This phenomenon has been dubbed GEO (Generative Engine Optimization). In this article, we analyze how SEO specialists influence neural network responses and why there is nothing to do in this niche without professional SMS services and scalable access management.
What is GEO and Why Is Testing Infrastructure Needed?
The essence of GEO (or AIO — AI Optimization) is simple: you need to convince the OpenAI algorithm that your brand is the most expert, authoritative, and trusted (E-E-A-T) source of information.
But how do you understand exactly what ChatGPT "thinks" about your brand? And how do you influence its "opinion"? This is where the need for access infrastructure arises. Professionals use services like CyberYozh App not for spam, but for solving strategic tasks:
Honest Visibility Monitoring (Share of Model): ChatGPT personalizes responses based on your previous dialogue history. If you constantly ask about your brand from one account, the neural network will start to "play favorites" with you. To see the real picture — how the AI responds to your potential customers — you need isolated test environments without digital memory or history to obtain objective data.
A/B Testing of Prompts and Strategies: You need to test 50 different question formulations (e.g., "Which CRM to choose?", "Top CRM systems", "Best CRM for small business") to understand exactly which scenarios exclude your brand from recommendations. Doing this from a single profile is risky (triggering limits) and inefficient (data bias).
Checking Local Results (Local GEO): ChatGPT's answers for a user in New York and a user in Berlin can differ cardinally. By using a combination of "Localized browser profiles + Regional proxies + Local phone number," you can check if the AI recommends your product in specific foreign markets.
Large-scale SEO Content Generation: To get into neural network responses, the internet must be filled with articles confirming your expertise (E-E-A-T). Creating hundreds of high-quality, structured articles for external platforms requires huge token limits, which quickly run out within a single subscription.
Experiments with Model "Training": Using test infrastructure to create dialogue chains that correct facts about a brand within a session. The hypothesis of many GEO specialists is that massive, correct signals can eventually update association weights within the model (so-called Agentic Influence).
Is a Phone Number Needed in 2025? Reality vs. Marketing
OpenAI has indeed simplified access to its products. If you are a regular user connecting from home Wi-Fi, you might have noticed changes:
Basic Access: ChatGPT (GPT-3.5/4o-mini) can be used even without registration, but with limited functionality and no history saving.
Simplified Login: Often a Google/Apple ID or email confirmation is enough to create a single account.
What is the specific issue for a professional then?
Soft rules apply to users with a high "Trust Score." As soon as you start engaging in large-scale testing or promotion, the situation changes drastically.
OpenAI security systems require SMS verification in the following cases:
Network Activity: Using proxies or VPNs is often a trigger for additional verification.
Lack of Digital History: New browser profiles have no accumulated cookies, which algorithms view as a sign of a new session.
Scaling Access: If a second or third session is created from the same "hardware" or subnet, an SMS confirmation request is mandatory.
API Access: To obtain API keys (necessary for product integration), phone verification remains the standard for identity and billing confirmation.
VoIP Blocks: Most free virtual numbers (Google Voice and public SMS receiving services) are blocked by the system for corporate registration.
Geo-mismatch: If you log in from a German IP address but enter an Indonesian number, the system may flag this as data inconsistency.
Age Verification: Since September 2025, OpenAI has introduced strict control. If a profile seems suspicious to the system, extended identification may be required.
Therefore, to create a reliable access base, the combination of "Clean Proxy + Residential Number" remains the best method.
Technical Stack for Successful Registration
To ensure your test sessions are stable, use the following algorithm:
1. Digital Fingerprint Preparation
Use specialized profile management tools to create an isolated and secure test environment for each session. This ensures the purity of the collected data.
2. High-Quality Proxies
This is the foundation. You need static residential proxies, which provide high connection quality.
Solution from CyberYozh App: Our proxies provide high trust and anonymity, making them ideal for working with various platforms, including OpenAI. We recommend matching the proxy to the country of the future phone number — this reduces the risk of an additional verification request (Geo-mismatch).
3. Virtual and Residential Numbers. SMS Activation
OpenAI requires reliable phone numbers to confirm high-quality, legitimate access.
Virtual Number vs. Residential: Which to Choose for OpenAI?
The difference between them is fundamental for verification systems:
Virtual Numbers (VoIP): These are numbers created via software through internet telephony. They are cheap, but large platforms may restrict their use.
Residential Numbers (Non-VoIP): These are numbers physically tied to real SIM cards from mobile operators. In databases, they are identified as regular mobile phones.
Important: To ensure stable access to OpenAI and work via API, we recommend using residential numbers.
Criteria for Choosing an SMS Service:
Wide Range of GEOs: Experienced marketers often choose trusted regions (Poland, Baltic states, Indonesia) with optimal costs.
SMS Delivery Speed: The code from OpenAI doesn't last long. The service must provide the code instantly.
Privacy and Number Purity: A reliable service guarantees that for the duration of the activation, this number belongs only to you.
Refund Policy: If the code doesn't arrive, the money should be returned to the balance automatically.
CyberYozh App fully meets these requirements. We provide access to thousands of numbers worldwide, filtered for stable performance with Google, OpenAI, and Telegram.
Step-by-Step Guide: Setting Up Access Correctly
Set up the Session: Launch an isolated browser profile with a connected proxy (e.g., USA).
Go to CyberYozh App: In the "SMS Activation" section → "Residential Numbers", select the service "OpenAI".
Select Country: Ideally, it should match the proxy region.
Buy a Number: Copy the received phone number.
Start Registration in OpenAI: Enter email and password. When the site requests a phone number, paste the purchased number.
Get the Code: Return to your personal dashboard on the CyberYozh App website and wait for the verification code to appear.
Complete Registration: Enter the code on the OpenAI website.
Important: After successful registration, let the environment "rest" for a couple of hours before active use. This ensures session stability.

Important Note: Security and Platform Rules
We strongly recommend approaching the process consciously and considering OpenAI's rules:
TOS Compliance: Official OpenAI rules (Terms of Service) govern the use of the platform. We recommend using the infrastructure exclusively for legitimate QA tests and marketing research.
Legislation: Always consider local regulations when collecting data and conducting marketing experiments.
Corporate Solutions: If your task is to provide team access to ChatGPT, consider creating official Organizations within OpenAI. This is the optimal way to manage access for multiple users.
