The same proxy can "kill" an account in one task and work perfectly in another — it all depends on whether it has a sticky session or rotation. We analyze this through 6 real scenarios: farming Facebook Ads, managing SMM profiles, parsing marketplaces, multi-accounting on Avito, account registration, and ad testing — what to choose in each case to avoid wasting money and time.
Sticky session and rotation: what's the difference
A sticky session is a mode where the same IP address is assigned to a profile for a certain period: from 10 minutes to 24 hours, and sometimes even longer. While the session is alive, all requests come from the same IP, as if you are working from home or the office. Rotation, on the other hand, means the IP changes at a specified interval or with each new request, and one session can "pass" through dozens of different addresses.
For platforms that monitor account behavior (Facebook, Instagram, TikTok), changing the IP mid-session looks like suspicious activity — the system sees a login from one country and a minute later an action from another, triggering a check or block. For tasks where the binding to one address is not important, but volume and speed are (parsing catalogs, collecting prices), rotation is the only reasonable option, as one IP quickly gets banned due to the frequency of requests.
The key rule: if the profile has a "personality" — account, cookies, action history — use a sticky session. If the task is impersonal and does not require authorization from the same user — use rotation. We will further analyze this rule in 6 specific tasks.
Case 1: farming Facebook Ads and TikTok Ads
When warming up Facebook Ads and TikTok Ads accounts, moderation analyzes the stability of the environment: IP, geolocation, time zone, browser fingerprint. If an account logs in from Moscow, and 15 minutes later from Germany, the system considers this suspicious for compromise or multi-accounting and freezes the ad account even during the warming phase.
Here, a sticky session is needed with an IP fixed for at least a day, preferably for the entire lifespan of the profile. Arbitrageurs managing 20-50 accounts simultaneously usually bind one static IP to one profile in an anti-detect browser permanently — just as if each account "lived" on its own separate device. For this task, residential proxies are well-suited — they appear as regular home IPs and do not raise suspicions during platform checks.
It is also important to consider TikTok Ads: this platform strictly monitors the match between IP geolocation and the device's time zone. If the proxy is located in Poland, but the profile system indicates a Moscow time zone — this is an immediate red flag. Therefore, when farming, it is crucial to synchronize not only the IP but also the time zone, interface language, and screen resolution in the anti-detect browser with the parameters of the country where the proxy is physically located.
Case 2: managing client SMM accounts
SMM agencies managing 10-50 Instagram and TikTok accounts for different clients operate on a similar logic as arbitrageurs, but with less intensity of actions. Here, a sticky session is also a mandatory condition, but the duration requirements are softer: fixing the IP for the entire duration of the project is not always necessary; it is sufficient to maintain the binding for 24-72 hours with a planned change every few days, as long as it does not interfere with the login history.
The main danger for SMM specialists is the so-called chain bans: if several client accounts operate through the same IP, and one of them gets blocked, the platform may "ring" the linked profiles and block them all at once. Therefore, it is important not just to use a sticky session but also to allocate a separate IP for each account, rather than economizing on a shared pool. For Instagram and TikTok, mobile proxies are particularly effective — they are less likely to come under suspicion because mobile operators often use NAT, where thousands of real users are hidden behind one IP, reducing the risk of false blocking due to "suspicious matches."
In Dolphin Anty or AdsPower, it is convenient to create profile groups with a fixed proxy for each and an automatic IP check enabled at each launch — if the service suddenly "drops" or changes the address, you will see it before you log into the client account.
Case 3: parsing prices on Wildberries and Ozon
Monitoring competitor prices on marketplaces is a different kind of task: here, a "profile" with history is not needed; what is required is a volume of requests without blocking due to frequency. Wildberries and Ozon track the number of requests from one IP in a unit of time, and if the limit is exceeded, they issue a captcha or a temporary ban on the address.
Here, rotation is definitely needed — the more frequently the IP changes, the lower the chance of hitting the request limit from a specific address. Sellers who monitor thousands of product cards daily set up rotation with intervals from one request to several minutes, depending on the volume. For this task, data center proxies are well-suited — they respond faster and are cheaper for large volumes of traffic, and the high anonymity of residential IPs is not critical here, as the task does not require authorization in a personal account.
An important nuance: if parsing is done non-anonymously through the seller's personal account (for example, to check one's own prices in different regions after authorization), then it is worth switching to a sticky session at least for the duration of one parsing session, to avoid being logged out every few minutes.
Case 4: multi-accounting on Avito
Avito is one of the most sensitive platforms to multi-accounting. The platform can easily recognize the connection between ads if they are published from the same device, browser, or IP range. The same logic applies as with social networks: each account should have its own stable IP for a long time, with no rotation within a single ad placement session.
A feature of Avito is that geography is literally important — if a seller from Krasnodar posts an ad for an apartment sale in Novosibirsk, it immediately raises suspicion with the security algorithms. Therefore, proxies should be chosen not just for being "stable," but with an exact match of the placement region. A sticky session with a fixation for 7-30 days is standard practice for those who manage 5-15 accounts for different cities simultaneously.
In the anti-detect browser for Avito profiles, it is recommended to additionally fix not only the IP but also cookies, local storage, and Canvas fingerprint — Avito analyzes the combination of these parameters, not just the address.
Case 5: registering and verifying new accounts
The registration moment is the most vulnerable stage in the life of any account, whether it be Facebook, Instagram, Google, or a marketplace. At this step, the platform first records the device-IP-action link, and any instability here is fatal.
At the registration stage, a sticky session is needed without exceptions, preferably with a time buffer — the IP should remain unchanged not only during the form filling but also during email or SMS confirmation, the first login, and profile setup. If the IP changes even once between registration and the first login, many services automatically mark the account as suspicious and require additional verification, and sometimes block it immediately.
After successful registration and "warming up" the account for several days with the same IP, one can consider switching to a longer but still stable mode — there should be no sharp rotation at this stage at all.
Case 6: testing Google Ads and Yandex.Direct ads by region
Marketers checking how ads appear in Google Ads and Yandex.Direct for users from different cities and countries need a third approach — neither pure rotation nor long sticky sessions, but a controlled change of IP between individual checks.
Within one check (for example, to see the ad output for a user from Kazan), a sticky session is needed for a few minutes, so the system has time to "understand" the geolocation and show relevant ads. However, between checks for different regions, the IP should completely change — this resembles rotation, but managed manually or by schedule, not automatically with each request.
Such a hybrid mode is usually set up manually: in the anti-detect browser, several profiles are created, each tied to its region through a separate sticky proxy, and the marketer simply switches between profiles rather than relying on automatic rotation within one window.
Summary table: what to choose for each task
| Task | Session mode | Recommended type of proxy |
|---|---|---|
| Farming Facebook Ads / TikTok Ads | Sticky, 24 hours+ | Residential |
| SMM accounts Instagram / TikTok | Sticky, 24-72 hours | Mobile |
| Parsing Wildberries / Ozon | Rotation, on demand | Data center |
| Multi-accounting on Avito | Sticky, 7-30 days | Residential |
| Registering new accounts | Sticky, no change until warming is complete | Residential / mobile |
| Testing Google Ads / Yandex.Direct by region | Hybrid: sticky for checking + change between regions | Residential |
Settings in Dolphin, AdsPower, Multilogin, and GoLogin
In all popular anti-detect browsers, the setup logic is similar. In Dolphin Anty, when creating a profile, you need to go to the proxy settings section, insert the host, port, username, and password, choose the SOCKS5 or HTTP type, and specify the required session mode — if the proxy provider supports the sticky parameter in the connection string itself (for example, by adding a session identifier to the username), just write it there without additional settings in the browser itself.
In AdsPower, the logic is similar: the "Proxy" section in the profile settings, choosing the connection type, and inserting access data. For bulk application of rotation to several profiles simultaneously, it is convenient to use the mass proxy import function via a CSV file, where each profile has its own IP or session key.
Multilogin and GoLogin allow additionally linking proxies to the device's "fingerprint" — this is especially important for sticky sessions, as changing not only the IP but also the digital fingerprint simultaneously looks suspicious to the platform. It is recommended to fix both parameters simultaneously for the entire lifespan of the profile, not just the IP address.
For tasks with rotation (marketplace parsing), an anti-detect browser is usually not required at all — it is sufficient to set up IP changes at the level of the proxy provider itself or through request parameters in the parser, specifying the session change interval in minutes or after each request.
Common mistakes when choosing session mode
The first and most common mistake is using rotation where a sticky session is needed. Beginners in arbitrage sometimes think that changing the IP every few minutes "increases anonymity" and protects the account, while in reality, this is a direct path to blocking for suspicious activity.
The second mistake is the opposite: using the same sticky IP for parsing large volumes of data. This leads to the quick blocking of the address by the marketplace and the loss of all current data extraction.
The third common mistake is economizing on the number of IPs in multi-accounting: if 10-20 accounts operate through the same sticky proxy, the risk of chain bans sharply increases because the platform can easily see the connection between profiles by matching addresses, even if the sessions are properly fixed.
The fourth mistake is ignoring the match between geolocation and time zone. Even the correctly chosen session mode will not save you if the IP is from Germany, while the system settings of the profile indicate a Russian time zone and locale — such discrepancies are automatically recorded by the platform.
Conclusion
The choice between sticky session and rotation is not a universal rule but a solution for a specific task. For anything related to a personal account and its history — ad farming, SMM, Avito, registration — a stable sticky session with the longest possible IP fixation is needed. For bulk and impersonal operations — price parsing, data collection from marketplaces — only rotation works; otherwise, you will quickly hit request limits.
If you plan to manage multiple social media accounts or warm up ad accounts, we recommend trying residential proxies — they provide a stable IP with a high level of trust from platforms and minimal risk of blocks during long sticky sessions.
