How BotRefund Identifies Invalid Traffic in Your Google Ads Account
BotRefund detects invalid traffic by analyzing real-time behavioral signals, IP patterns, and session dynamics on your landing pages. It captures GCLIDs with behavioral evidence to build refund-ready reports for Google Ads disputes.
✓ Built for advertisers who need clear, refund-ready traffic evidence.
BotRefund identifies invalid traffic in your Google Ads account by cross-referencing every ad click against a set of behavioral, technical, and session-based signals. When a visitor lands on your site after clicking a Google ad, the BotRefund script collects data on their mouse movements, click timing, scroll behavior, and device characteristics. It then compares that data against known bot signatures and suspicious patterns. If the session matches a bot profile, BotRefund flags it and captures the Google Click ID (GCLID) along with evidence of invalidity. That evidence is used to generate a refund dispute report you can submit to Google.
Step 1: Install the BotRefund Script
Before any detection can happen, you need to add the BotRefund JavaScript snippet to your website. The script is lightweight and loads in about one minute. No credit card is required to start. Once installed, it begins monitoring all traffic on your site, including clicks from Google Ads.
Step 2: Collect Behavioral Signals in Real Time
For every visitor, BotRefund records a range of behavioral signals. These include pointer movement patterns, scroll depth, time on page, click intervals, and interaction with page elements. The goal is to distinguish a human user from a bot by looking for natural imperfections like mouse tremor and variable speed. Bots often move in perfectly straight lines or at inhumanly fast speeds.
Step 3: Compare Signals Against Known Bot Patterns
BotRefund maintains a library of bot signatures, including patterns from click farms, residential proxy botnets, and automated scripts. It checks each session against these patterns. For example, if a session shows a grid-aligned movement path or superhuman input speed (under 1 millisecond), it is flagged as suspicious. The tool also uses IP filtering to block known data center ranges and VPN endpoints.
Step 4: Use Honeypot Traps and Trap Behaviors
BotRefund places hidden page elements that are invisible to humans but detectable by bots. When a bot interacts with these honeypot traps, it reveals itself as non-human. The tool also watches for ghost click detection — clicks that happen without the natural sequence of human intent, such as clicking before the page has fully loaded.
Step 5: Capture GCLIDs with Behavioral Evidence
For every flagged session, BotRefund automatically captures the Google Click ID (GCLID). This identifier links the click back to your Google Ads account. The tool also saves a detailed behavioral log of the session, including timestamps, movement data, and device fingerprints. This evidence is formatted into a refund-ready report that meets Google's requirements for invalid activity credit claims.
Step 6: Generate Audit-Ready Refund Dispute Reports
BotRefund compiles the captured GCLIDs and behavioral evidence into a structured report. You can download this report and submit it directly to Google to request a refund for invalid clicks. According to BotRefund's audit data, the tool helps achieve an 83% refund success rate for high-volume advertisers.
What Behavioral Signals Does BotRefund Analyze?
The tool examines several specific behaviors:
- Pointer behavior: Robotic linear mouse movements that lack natural curves.
- Motion behavior: Absence of humanlike mouse tremor — bots have perfectly smooth motion.
- Speed behavior: Superhuman input speed, such as clicks under 1 millisecond.
- Path behavior: Grid-aligned movement patterns instead of natural curves.
- Engagement behavior: Absence of clicks or scrolling — sessions that are too static.
- Session behavior: Unnatural session durations that are too short, too long, or too uniform.
How IP Filtering and VPN Detection Work
BotRefund maintains a constantly updated list of known data center IP ranges and VPN endpoints. When a visitor arrives from one of these IPs, the session is flagged as potentially invalid. The tool also detects VPN usage by analyzing network latency and IP geolocation inconsistencies. This catches bots that hide behind residential proxies or VPN services.
The Role of Honeypot Traps in Catching Bots
Honeypot traps are invisible form fields, links, or buttons placed on your landing page. Humans never see or interact with them, but bots often fill them out or click on them. BotRefund monitors interactions with these hidden elements. If a bot triggers a honeypot, it is immediately flagged and added to the evidence log.
Session and Engagement Pattern Analysis
BotRefund looks at the overall behavior during a session. A human visitor typically scrolls, pauses, clicks on relevant content, and may navigate to other pages. A bot session often has no scrolling, no field corrections, and a uniform click path. The tool also checks for sudden bursts of traffic from the same IP or device, which suggests automated clicking.
Capturing Evidence for Google Ads Refunds
To get a refund from Google, you need more than a suspicion of bot traffic. You need proof. BotRefund provides that proof by capturing the GCLID, the behavioral log, and a timestamp. This evidence is packaged into a report that Google's support team can review. Without this evidence, Google's automated filters may not catch the invalid traffic, since they catch less than 50% of sophisticated invalid traffic.
Limitations of Automated Detection
No detection system is perfect. BotRefund may miss some extremely sophisticated bots that mimic human behavior perfectly. Also, the tool only works on traffic that reaches your website — it cannot detect invalid clicks that happen before a user lands on your site (e.g., in ad auctions). Additionally, the quality of evidence depends on proper script installation and page load speed. Advertisers with very low traffic volumes may not see enough data to build a strong refund case.

Frequently Asked Questions
Does BotRefund block bot traffic in real time?
Yes, BotRefund filters invalid traffic during the session. It prevents the session from triggering your conversion pixel, which protects your Smart Bidding from optimizing toward bot traffic.
How does BotRefund differ from Google's own invalid traffic detection?
Google's automated filters catch only a portion of invalid traffic, especially sophisticated botnets. BotRefund uses client-side behavioral signals that Google cannot see, and it provides evidence you can submit to get a refund.
What is a GCLID and why is it important?
A Google Click ID (GCLID) is a unique identifier attached to each ad click. BotRefund captures the GCLID of suspicious sessions to link the invalid activity back to your Google Ads account for refund requests.
Can BotRefund detect click farms?
Yes, click farms often produce uniform behavioral patterns, such as identical mouse movements or click timings. BotRefund's behavioral analysis flags these patterns even if the IP addresses appear legitimate.
What happens if a bot is using a residential proxy?
Residential proxies hide the bot's real IP. However, BotRefund's behavioral analysis still catches the unnatural movement and timing patterns, regardless of the IP address.
How long does it take to get a refund after submitting a report?
Refund timelines vary by Google's review process. Some advertisers receive credits within a few weeks, while others may take longer. BotRefund's evidence reports are designed to speed up the process by providing clear proof.
Is BotRefund suitable for small advertisers?
BotRefund offers a free tier and pricing that scales with ad spend. Small advertisers can use the tool to detect and recover wasted budget, though the refund success rate is highest for larger accounts.
