System Requirements

• A stable internet connection.
• At least 8 GB of RAM to work seamlessly with multiple browser profiles and tabs.
• At least 2 GB of free disk space for logging, screenshots, and reports.

What to Install and Configure

• A modern browser version.
• A password manager or secure notebook to store logins and proxy addresses.
• Website tools for verification: IP check, DNS Leak Test, Proxy Checker, proxy calculator, latency map, and browser fingerprint generator. These will help ensure you are in the desired region and that your network profile matches the target audience.

Creating Backups

• Export your Yandex.Direct campaign settings to a file if you plan to change display parameters and strategy. This will allow you to revert changes.
• Make a copy of important reports and dashboards in analytics to maintain a baseline for subsequent comparisons.

⚠️ Attention: Before making changes to your campaigns, create duplicates of ad groups and use them for A/B testing. Avoid making abrupt changes to the original until the verification is complete.

Basic Terms

Before diving into practice, let’s clarify key terms and principles so that you understand the purpose of each step and what to expect.

• Mobile Proxies—a connection through an IP address assigned to a mobile network operator. This connection allows you to see ads as a real user of mobile internet would in a specific region.
• IP Rotation—changing the IP address based on a timer, upon request (API), or via link. This is needed for repeated display checks and to reduce the likelihood of personalized results.
• Geo-verification—confirming that ads are genuinely shown to users in the target region specified in the campaign settings.
• A/B Testing of Creatives—comparing two ad variations based on CTR, conversions, click cost, and secondary metrics to select the most effective one.
• Click Fraud—artificial or low-quality clicks that distort statistics and increase costs. The goal is to identify patterns and document evidence.
• Browser Fingerprint—a set of browser and device parameters. It is important to ensure that your tests mimic the view of a real user rather than repeating the same "fingerprint".

Tip: Aim to use at least 2–3 sessions with different IPs and slightly varying browser fingerprints in each region to mitigate personalization effects and obtain a more honest picture.

Step 1: Plan Checks and Choose Regions

Goal of This Step

To determine the list of target regions, types of platforms, device types, and key queries for subsequent verification of displays.

Step-by-Step Instructions

1. Open your campaign in Yandex.Direct and navigate to geo-targeting settings. Write down the regions, cities, and districts you want to verify displays for.
2. Compile a list of key queries for each ad group. Add branded, high-frequency, and some mid-frequency phrases that actually trigger displays.
3. Identify platform types: Yandex search, Yandex Advertising Network (YAN), Yandex services with ad blocks. For search, it’s crucial to check positions and visibility. For YAN, check if the ad appears on relevant platforms.
4. Separate checks by device. Minimum: mobile phone. If possible, add a tablet. This is important if you have separate creatives and landing pages for different devices.
5. Formalize your view scenario: 2–3 queries, a 20–40 second pause between actions, navigating to page 2 of results if necessary, 1–2 transitions to content pages before searching again. This simulates natural behavior, reducing personalization.
6. Define time windows: check morning, afternoon, and evening. Some ads are scheduled or have budget limitations that impact evening displays.

Important Notes

• Do not use the same search scenario multiple times in a row. Alternate queries.
• Document the time, region, query, device, and result in a spreadsheet.

Tip: For planning, it’s convenient to create a table with columns: Date/Time, Region, Device, Platform Type, Query, Ad Position, Extension Visibility, Notes.

Expected Result

You’ll have a clear matrix where rows are regions and columns are queries and devices. This is your roadmap for verification.

Possible Problems and Solutions

• The query list is too large. Solution: select 3–5 queries per ad group for initial verification, leaving the rest for selective checks.
• Difficulty selecting time. Solution: use three time windows—9:00–11:00, 14:00–16:00, 19:00–21:00.

✅ Check: You have a validation plan ready for 1–2 days, with clear time slots and a list of queries for each region.

Step 2: Choose and Set Up Mobile Proxies

Goal of This Step

Select mobile proxies for the necessary regions and prepare the setup for stable and accurate performance.

Step-by-Step Instructions

1. Identify the countries and regions where displays should occur. If you’re working in a specific city, choose mobile proxies with geography from that city or the nearest locality.
2. Select the protocol type: HTTP(S) or SOCKS5. Both are suitable for verification. Use whichever is more convenient in your browser or tool.
3. Set up IP rotation. A timer of 10–30 minutes is recommended. For quick repeat checks on adjacent queries, use manual switching via link or automatic by API.
4. Check the IP using an IP verification tool. Ensure that the city and carrier detection match the target region and mobile network.
5. Perform a DNS Leak Test. Ensure DNS queries also align with the target region and do not “leak” your information.
6. Check speed and latency using the latency map. If the ping is too high, select a closer region in the network topology or another mobile network.
7. Use Proxy Checker to ensure the proxy is active, authenticates correctly, and supports the stated protocols.

Important Notes

• Mobile IPs change naturally. This is normal. The goal is to control rotation and confirm the region before each series of checks.
• Store your proxy access credentials in a password manager.

Tip: To calculate the necessary number of IPs and sessions, use a proxy calculator. It will help you understand how many concurrent streams you’ll need for your plan.

Expected Result

Active mobile proxies with clear rotation, verified by IP and DNS, and with acceptable latency to target services.

Possible Problems and Solutions

• The IP does not match the city. Solution: change the node in the same region, perform manual rotation, or increase the timer between changes.
• High ping. Solution: choose another pool of IPs or a different operator within the target country.

✅ Check: Based on the IP and DNS verification results, you see the target region and mobile operator, and the proxies pass availability checks with acceptable delays.

Step 3: Prepare the Browser and Device Fingerprint

Goal of This Step

Create an environment as close as possible to a real mobile internet user in the target region in order to make the verification results objective.

Step-by-Step Instructions

1. Create a new clean browser profile. This will exclude the influence of your previous searches and personalization.
2. Set a user agent for a mobile device. You can use standard emulation modes in the browser’s developer tools.
3. Using a browser fingerprint generator, prepare the fingerprint parameters: screen resolution, language, timezone, font list, and WebGL settings. Choose typical settings for the region.
4. Connect the proxy at the browser level. Specify the address, port, username, and password. Save the settings.
5. Open an IP verification site. Ensure the city, region, and carrier are correct. Confirm the timezone and interface language.
6. Open the Yandex search page. Check which region is indicated in the header. If necessary, refresh the page after rotation to ensure the region matches your verification plan.

Important Notes

• Do not log in with personal accounts during checks. Excessive personalization will distort results.
• Change fingerprints when moving to a new region or a new set of queries.

Tip: Keep a fingerprint log: which combination of settings was used for which region and query. This will allow you to reproduce the environment accurately in contested situations.

Expected Result

You should have a clean mobile browser profile connected to a mobile proxy, with the correct region and realistic fingerprint.

Possible Problems and Solutions

• The region in the header does not match the target. Solution: perform IP rotation and restart the profile. Check language and geolocation settings in the browser.
• Pages load slowly. Solution: check latency on the latency map, if necessary, change the IP pool.

✅ Check: The IP verification page displays the target city, the correct target region is shown in Yandex’s browser, and the fingerprint has been recorded.

Step 4: Conduct Verification of Displays and Positions

Goal of This Step

To understand whether the ad is displayed in the selected region, at what positions, and with which extensions, as well as to record results for reporting.

Step-by-Step Instructions

1. Select the first target region and activate the corresponding mobile proxy. Check the IP and DNS before starting.
2. Open the mobile version of the Yandex search page. Ensure the region indicated in the header corresponds to the plan.
3. Enter the pre-prepared query. Click Search.
4. Review the results on the first page. Locate your ad. Note the position: special placement, top block, or bottom block.
5. Record the presence of extensions: quick links, clarifications, phone number, address, rating, prices, images. Note the correctness of the display.
6. If the ad does not appear on the first page, gently scroll down and move to the second page. Note the absence or presence of the display.
7. Take a screenshot of the screen (if it does not conflict with your security policy). Name the file according to this template: date_region_query_position.
8. Pause for 20–40 seconds. Execute the second query from the list for the same region. Repeat the result recording.
9. Change the IP through rotation. Repeat checks for 1–2 queries to eliminate any personal factor of a single IP.

Important Notes

• Do not click on your own ads during the test phase. If you need to check the transition, use the ad diagnostics and preview mode in Yandex.Direct or utilize provided interfaces without actual click charges, if available in your interface.
• Document all discrepancies and take screenshots indicating the time.

Tip: During prolonged series of checks, parallelize the processes: one specialist checks and records screenshots, while the other maintains tables and marks the presence of extensions and positions.

Expected Result

For each region and each query, you have a record: whether there was a display, at which position, how the extensions looked, with attached screenshots and time of verification.

Possible Problems and Solutions

• The ad is not visible. Causes: budget exhausted, scheduling restrictions, low bids. Solution: check the campaign status in Yandex.Direct, temporal targeting, and bids.
• Displays exist, but without extensions. Solution: check the correctness of filling in extensions and their compliance with moderation policies. Ensure extensions are available for this format and device.

✅ Check: In the table, there are at least two checks on different IPs in each region, with positions and extensions noted, and the time of verification documented.

Step 5: In-Depth Geo-Verification and Behavior Scenarios

Goal of This Step

To check displays in neighboring areas, suburbs, and various user behavior scenarios to ensure the stability of geo-targeting and eliminate extended displaying outside the target zone.

Step-by-Step Instructions

1. Select two neighboring districts to the target region. Connect mobile proxies for each.
2. Repeat the queries from the plan. Verify whether the ad displays in these neighboring areas.
3. Change the scenario: first open the regional news page, then return to search and execute the target query. This simulates local behavior.
4. Check displays for branded queries and general commercial queries. Compare the ad's presence.
5. If distance services are available, check if the option for extended geo-targeting is enabled in the campaigns. If displays suddenly appear outside the target zone, note this as a special case for further analysis.
6. Make records for each area: yes or no, position, ad format, notable differences from the main region.

Important Notes

• Neighboring zones often provide a picture of "leakage" in displays. This is not always an error, but it is important to understand the scale.
• Behavior scenarios help verify if preliminary content affects the relevance of displays.

Tip: If you work with a specific offline business, additionally check displays near key locations: train stations, business districts, and educational campuses. This provides useful insights into real visibility.

Expected Result

A picture of neighboring districts and different user behavior scenarios. You understand where displays are stable and where discrepancies may occur.

Possible Problems and Solutions

• Displays in "unnecessary" districts. Solution: review geo-targeting and adjustments in Yandex.Direct settings. Limit areas if necessary.
• Strong variation in positions. Solution: check competition at different times and adjustments to mobile device bids.

✅ Check: Rows have been added to the table for suburbs and neighboring districts, differences noted, and conclusions regarding the correctness of geo-targeting have been made.

Step 6: A/B Testing of Creatives with Audience Perspective

Goal of This Step

To compare two versions of ads in real mobile sessions and select the more effective one based on visibility, clickability, and display quality.

Step-by-Step Instructions

1. Create a duplicate ad group in Yandex.Direct for A/B testing. In the first group, keep the current creative, and in the second, change the title, image, clarifications, or quick links.
2. Enable even ad rotation in the group if this option is available. If not, plan equal display intervals and monitor manually.
3. Define key metrics: CTR, landing page scroll depth, conversion to target action, click cost, and lead cost.
4. For visual checks, use mobile proxies with different operators in the same region. View results from two to three IPs for each creative variant.
5. Document how creatives appear on different devices: title length and cropping, visibility of quick links, image and extension display.
6. Keep track of time and IP for each view. This will help correlate observations with data in statistics.

Important Notes

• Do not change multiple creative elements in one test at once. Aim to modify 1–2 parameters to understand what caused an effect.
• Document hypotheses beforehand: "A short title will increase CTR," "Adding a phone number will improve trust," etc.

Tip: For services with maps and addresses, check if the address block is visible and formatted correctly. This often impacts mobile CTR.

Expected Result

Two creatives tested on mobile sessions. Observations on visibility and display quality gathered. You begin collecting statistics for the final comparison.

Possible Problems and Solutions

• Creatives are displayed unevenly. Solution: check rotation settings and competition on bids. Adjust bids temporarily if necessary.
• Indiscernible effects. Solution: extend the test to 3–5 days to gather more traffic before drawing conclusions.

✅ Check: The table includes rows for each creative, time, IP, and observations. Creative rotation is enabled, and hypotheses are documented.

Step 7: Validate Landing and Conversion Path

Goal of This Step

Ensure that after clicking, mobile users see the correct landing page, forms function properly, and analytics captures visits and goals.

Step-by-Step Instructions

1. Prepare a testing environment where you can simulate clicks without incurring costs (ad diagnostics and previews if accessible; alternatively—temporary UTM tags on chosen test URLs and direct access).
2. Open the landing page from the mobile profile and check adaptability: formatting, speed, readability, button clickability.
3. Check key forms: proper validation, easy input from the mobile keyboard, clear error messages.
4. Ensure analytics records the visit with UTM tags and events: scroll, click on the button, form submission, call to the phone number if call tracking is set up.
5. Repeat the check with 1–2 new IPs and slightly altered device fingerprints. Compare behavior and speed of the page.

Important Notes

• Speed is critical for mobile traffic. If TTFB or CLS are high, this can reduce conversions.
• Tagging must be consistent: ensure UTM tags are identical in both creatives during A/B testing.

Tip: Use a form error log. If errors are minimal, incorporate test checks with deliberately incorrect data to see validation messages from the user’s perspective.

Expected Result

Landing pages are correctly displayed on mobile devices. Goals and events are recorded, and test submissions reach CRM.

Possible Problems and Solutions

• Slow loading. Solution: optimize images, implement lazy-load, check server delays.
• Events not being recorded. Solution: check counters in the code and goal settings in analytics.

✅ Check: Analytics shows visits with UTM tags and test events. Forms work without issues, and speed is acceptable for mobile networks.

Step 8: Identify Signs of Click Fraud

Goal of This Step

Learn to recognize suspicious clicks and formalize evidence for actions in the advertising cabinet and analytics.

Step-by-Step Instructions

1. In the Reporting Master or campaign statistics, export clicks broken down by platforms, time, and devices. Compare with a pre-check period.
2. Identify anomalies: sharp spikes in CTR at night, clicks from atypical YAN platforms, repeated clicks with close timestamps.
3. Match web server logs with analytics: highlight IPs and ASNs from which clicks are coming. Pay attention to an unusually high percentage from one operator or IP range.
4. Check suspicious IPs via Proxy Checker. Determine if they belong to known data centers, uncommon for your audience. Mobile audiences typically feature mobile ASNs.
5. Assess traffic quality: high bounce rates, super short sessions with no interactions, lack of scrolling can indicate fraud.
6. Document cases: date, time, IP, operator or ASN, platform, site behavior. Prepare excerpts from logs and screenshots of graphs.

Important Notes

• One sign alone does not prove fraud. Look for a combination: behavior, sources, time of day, frequency.
• Segmentation by regions is crucial. Fraud can be localized, masquerading as mobile users from neighboring regions.

Tip: Set up alerts in analytics: triggers for CTR or CPC spikes, increased bounce rates. Early notification saves budget.

Expected Result

You have a list of suspicious clicks with supporting data. Understanding which platforms or time windows pose risks.

Possible Problems and Solutions

• Insufficient data for conclusions. Solution: increase the analysis period to 2–4 weeks to gather more statistics.
• Understanding ASN is difficult. Solution: document the communication operator and compare it with the typical profile of your audience.

✅ Check: There is a documented list of IP/ASN, time windows, and platforms with suspicious traffic. Logs excerpts and visualizations have been prepared.

Step 9: Implement Protective Measures and Document Cases

Goal of This Step

Set corrective measures in Yandex.Direct and your analytics against fraud, and prepare the evidence base.

Step-by-Step Instructions

1. In Yandex.Direct, clarify geo-targeting. Narrow down regions or disable extended geo settings in disputed zones if necessary.
2. Set expert limitations on impression frequency in YAN if your format supports this.
3. Add low-quality traffic sites to the negative list. Start with those that exhibit high bounce rates and cost per conversion.
4. Check bid adjustments by device. Lower bids where there are more suspicious clicks.
5. In analytics, set up segments for "suspicious users." Filter by ASN, time of day, and behavior. Use these in reports for regular monitoring.
6. Prepare a report: what happened, when, what actions were taken, how metrics changed after adjustments.

Important Notes

• Gradual adjustments are safer than abrupt changes. Monitor changes for 3–7 days before taking further action.
• Documents with logs and screenshots help in communication with colleagues and contractors.

Tip: Organize a folder with artifacts: reports, exports, screenshots, platform lists. Store versions with change dates.

Expected Result

Measures taken to reduce fraud, effects documented. There is a clear history of actions and results after changes.

Possible Problems and Solutions

• Accidentally disabling a useful site. Solution: restore the site if its quality improved post-adjustments, and observe for a week.
• No improvements. Solution: expand analytics, review creatives and targeting, check display schedules and bidding strategies.

✅ Check: Updated targeting and platform lists applied. Metrics improved or remained stable over the week.

Final Results Check
