You open the Facebook Ads Library or Google Ads Transparency Center, enter the competitor's domain — and see completely different creatives than those they are actually running for your audience. A familiar situation for marketers and arbitrage specialists who regularly monitor competitor ads. The problem is not with the monitoring tools, but with how advertising platforms determine who and what to show. We discuss 7 real reasons for distorted results and show how to obtain an objective picture.
Why accurate competitor ad monitoring is important for business
Monitoring competitor ads is not idle curiosity, but a working tool for arbitrage specialists and marketers. By analyzing a competitor's creatives, you can understand which offers are currently converting, which audiences are being targeted, which landing pages are used, and how often ads are updated. For SMM specialists and e-commerce sellers, it is a way to track promotions, prices, and promotional mechanics of competitors on Wildberries, Ozon, or Instagram.
The problem is that advertising platforms — Facebook Ads, Google Ads, TikTok Ads, Yandex.Direct — do not show ads to everyone in the same way. The algorithm decides what to show a specific user based on their geolocation, behavior history, device, and dozens of other signals. If you are viewing ads from your regular IP from the office, you do not see the same results that the target audience of the competitor sees in another region. This is the root of all the distortions that we will discuss below.
Reason 1: Geotargeting and local IP address
The most common reason for distortion is geolocation. Advertising accounts determine the country, region, and even city of the user based on their IP address. If a competitor has set up a campaign only for users in Moscow and St. Petersburg, and you access the Ads Library from an IP that the platform identifies as Kazakhstan or Ukraine, you simply will not see those ads — the system will show you what is available for your region, or nothing at all.
The same happens when analyzing local ads on Avito or Yandex.Direct: ads are tied to a specific city, and without changing the region, you will see results for your locality instead of the one you are interested in analyzing. This can be resolved by changing the IP address to the desired region — for this, arbitrage specialists and marketers use residential proxies with geotargeting for the required country or city, as they appear as regular IPs of real users and do not raise suspicions with anti-fraud systems.
Reason 2: Personalization based on browsing history
Facebook, Google, and TikTok personalize ads not only based on geo but also on behavioral data: which websites you have visited, which products you have searched for, which ads you have clicked on previously. If your personal account has already been "trained" by the algorithm based on interests in fitness, you will see ads from the fitness niche even when trying to monitor competitors in the finance or real estate sectors.
This is especially critical for SMM agencies that manage dozens of client accounts from different niches. The same browser with accumulated history shows different ads to different team specialists, making comparison of results meaningless. The solution is to use clean profiles without history for each monitoring task, preferably through an anti-detect browser with a separate cookie storage and a separate IP for each profile.
Reason 3: Device and connection type
Many advertisers in TikTok Ads and Facebook Ads set up separate campaigns for mobile devices and desktop, while some limit the display based on connection type — Wi-Fi or mobile internet. If you analyze a competitor's ads from a desktop via regular home Wi-Fi, and their campaign is set exclusively for mobile traffic via LTE, you will again see the wrong results or not see them at all.
This is especially relevant for mobile applications and games, where competitors often test creatives specifically through mobile networks of operators, as this corresponds to the real behavior of the target audience. To accurately replicate such conditions, arbitrage specialists use mobile proxies, which mimic the IPs of real cellular operators and allow you to see ads as they are viewed by mobile users in a specific region.
Reason 4: Browser fingerprint and anti-fraud systems
Modern advertising platforms analyze not only IP but also the digital fingerprint of the browser: screen resolution, time zone, system language, installed fonts, WebGL and Canvas parameters. If these parameters do not match the declared geolocation — for example, the IP shows Germany, but the time zone and system language are Russian — the platform's anti-fraud system may consider this an anomaly and show a "safe" averaged result instead of real local ads.
Therefore, experienced marketers set up monitoring through anti-detect browsers — Dolphin Anty, AdsPower, Multilogin, GoLogin, or Octo Browser. These tools allow you to create a profile with consistent parameters: IP of a specific country, corresponding time zone, browser language, and a unique but stable fingerprint. This is critical not only for viewing ads but also for safely farming advertising accounts without the risk of bans.
Reason 5: Ads Library restrictions by country
Facebook Ads Library and Google Ads Transparency Center have their own regional restrictions at the tool level, not just for ad results. In some countries, an extended filter by categories (political ads, social issues) is available, while in others, only basic keyword and page search is available. If you access the ads library from an IP in a region with limited access, part of the functionality and data on the competitor's creatives will be hidden.
A similar situation exists with the TikTok Creative Center: insights on trending ads and top creatives vary significantly depending on the selected region in the interface, which is partially tied to the geolocation of the IP. To gain full access to data from a specific country, you need to access it with an IP from that country, rather than relying on manual region selection in the interface — it does not always change the actual data output.
Reason 6: Competitor's creative rotation and A/B tests
Even if you have correctly set up geo and device, you may see "the wrong" ads simply because the competitor is testing several creative options simultaneously. Facebook Ads and TikTok Ads show different versions of an ad to different audience segments within one A/B test, and the rotation algorithm may show you only one of 5-10 options that the competitor is running.
This reason is resolved not by proxy settings, but by the monitoring methodology: you need to check the competitor's ads from several different profiles and IP addresses within the same region at intervals of several hours or days to gather a complete picture of all creative options. This is precisely why SMM agencies and arbitrage teams use a pool of residential proxies — each anti-detect browser profile receives its unique IP, thus collecting statistics on all of the competitor's ad options.
Reason 7: Cache and saved cookies
The last common reason is the banal browser cache and cookies from previous sessions. If you have already visited the competitor's page, clicked on their ads, or visited their site previously, the browser and advertising platform remember this interaction and may show you an "old" or already seen version of the ad instead of the current one. This creates the illusion that the competitor's ads are not updating, even though they have long changed for a new audience.
The solution is simple: before each monitoring session, clear cookies and cache, or use a separate isolated browser profile for each check. In anti-detect browsers, this is done in one action — creating a new profile with a clean data storage and a new IP address.
How to set up accurate monitoring: step-by-step scheme
To see competitor ads as the target audience sees them, you need to replicate the viewing conditions: correct geo, device, clean profile, and consistent fingerprint. Here is a working scheme:
- Install an anti-detect browser (Dolphin Anty, AdsPower, or GoLogin) and create a new profile for each monitoring task.
- Connect the proxy of the desired region in the profile settings — tab "Proxy" → select type SOCKS5 or HTTP → insert IP, port, username, and password of the proxy.
- Check that the time zone and system language in the profile match the selected geolocation — most anti-detect browsers do this automatically when connecting to a proxy.
- Open Facebook Ads Library, Google Ads Transparency Center, or TikTok Creative Center specifically in this profile, without using personal accounts and the main browser.
- For completeness of data, repeat the check in 2-3 different profiles with different IPs from the same region, to see all options of the competitor's A/B tests.
- Save screenshots and links to ads — advertising libraries periodically delete old records of inactive campaigns.
For monitoring local ads — for example, ads on Avito or Wildberries in a specific city — residential proxies with precise binding to the locality are suitable. For analyzing mobile campaigns in TikTok and Instagram, it is better to use mobile IPs, as they more accurately reproduce the conditions under which the real audience sees the ads.
Tools for monitoring competitor ads
In addition to proxies and anti-detect browsers, specialized services are used for systematic monitoring of competitor ads. They simplify data collection but do not solve the problem of geo distortions without proper IP configuration. A comparison of the main approaches:
| Tool / method | What it shows | Is proxy needed? |
|---|---|---|
| Facebook Ads Library | All active ads of the page, but without targeting | Yes, for full regional coverage |
| TikTok Creative Center | Trending creatives and top ads by country | Yes, output depends on IP |
| Google Ads Transparency Center | Ad announcements by domains and regions | Yes, for local campaigns |
| Manual viewing through profile | Real personalized output of the user | Mandatory |
| Monitoring Wildberries/Ozon/Avito | Promos, banners, and prices of a specific city | Yes, with geo-binding |
For one-time checks, one or two proxies with the required geo are sufficient, but if monitoring competitor ads is part of the regular work of an agency or arbitrage team, it is more profitable to set up a pool of proxies and assign profiles in the anti-detect browser for each region. For mass parallel monitoring from different countries and cities, data center proxies are suitable — they are cheaper than residential ones and provide stable speed for large volumes of checks, where masking as a real user is less important than speed and the number of parallel sessions.
Conclusion
Distorted results of competitor ads are not a failure of monitoring tools, but a consequence of how personalization and geotargeting algorithms work in Facebook Ads, Google Ads, and TikTok Ads. To see the same ads that the target audience of the competitor sees, you need to replicate their conditions: the correct region, device, clean browser profile without accumulated history, and consistent digital fingerprint. Having analyzed all 7 reasons — from geotargeting to browser cache — you now understand why monitoring without preparation provides an inaccurate picture, and how to fix it in practice.
If you regularly analyze competitor ads from different regions or monitor local listings on marketplaces, we recommend starting with residential proxies — they are the most versatile for simulating a real user from a specific city or country and minimize the risk of obtaining distorted or truncated results when checking advertising campaigns.
