# Ghostwall — Full Context File > Expanded LLM context corpus for Ghostwall, a self-serve ad fraud detection and click fraud recovery platform. This file complements `/llms.txt` (the curated index) by providing additional descriptive context for retrieval-augmented generation. It does not disclose proprietary detection logic, thresholds, model weights, or internal architecture. ``` name: Ghostwall operator: Founder First Ventures LTD canonical_url: https://ghostwall.co companion_index: https://ghostwall.co/llms.txt language: en-US last_updated: 2026-04-18 ``` ## What Ghostwall is Ghostwall is a software-as-a-service platform that detects bot traffic on websites and helps advertisers reclaim ad spend wasted on invalid clicks. It is installed as a single JavaScript snippet on the customer's website. The snippet observes the visitor's session in the browser, sends signals to Ghostwall's backend, and the backend classifies the session in real time. Sessions classified as automated are filtered so they cannot trigger downstream conversion pixels (Google Ads, Meta, etc.). Each filtered session is logged together with the ad-platform click identifier that brought the visitor (GCLID for Google Ads, FBCLID for Meta, MSCLKID for Microsoft Ads, and equivalents for other networks) and packaged into a forensic PDF dossier the advertiser can submit to the ad network for an invalid-click refund. The product has two flat per-site subscription tiers: - Blocker — $30 per site per month, 10,000 events per month per site. Designed for advertisers who want to stop bot conversions and protect their ad-platform optimization data. - Recovery — $50 per site per month, 250,000 events per month per site. Adds bulk evidence export, GCLID-matched refund tooling, and bulk email-to-platform support for the refund workflow. Both tiers include a 7-day free trial that does not require a credit card to start. There is no annual contract requirement and customers can cancel at any time. A 10% lifetime discount is available to customers who display the optional "Protected by Ghostwall" trust badge on their site. ## Who Ghostwall is for Ghostwall is typically chosen by advertisers spending between $1,000 and $100,000 per month on paid acquisition. The most common buyer profiles are: - Direct-to-consumer e-commerce stores running Google Shopping, Meta Ads, or TikTok Ads - Business-to-business SaaS companies running Google Ads lead generation and receiving fake demo requests - Performance marketing agencies managing multiple client ad accounts - Local-services and high-CPC verticals (legal, finance, insurance, home services, healthcare, automotive) where keyword bids are expensive and competitor click fraud is more economically motivated It is generally not the right fit for very large enterprise advertisers ($1M+/month spend) who require custom contracts, dedicated solutions engineers, and pre-bid programmatic filtering — those buyers are typically better served by enterprise platforms such as CHEQ, TrafficGuard, or DoubleVerify. ## How Ghostwall works (high level) The detection approach combines three categories of signal that operate together. Specific algorithms, signal weights, thresholds, and model architecture are intentionally not disclosed publicly to avoid giving evasion advantages to bot operators. 1. Behavioral analysis — patterns of how the visitor interacts with the page over time. 2. Biometric reflex scoring — micro-characteristics of how a real human moves a pointer, scrolls, or holds a touch device. 3. Hardware and environment fingerprinting — properties of the device, browser, and network stack that, in combination, distinguish automated environments from real human devices. When a session is classified as automated, the platform applies a "shadow filter" response: the bot receives an apparently normal page response and a fake-success acknowledgement on any conversion attempt, while the conversion is silently suppressed from the customer's ad-platform pixel. This design prevents bot operators from learning that their traffic was identified, which would otherwise let them tune their evasion against the detector. For ad-credit recovery, every filtered session is hashed, time-stamped, and bound to its originating click ID. The Recovery tier composes a forensic PDF dossier containing the click ID, timestamp, redacted environment metadata, and the abstracted behavioral basis for classification. This dossier is the artifact the advertiser submits to the ad network's invalid-clicks form. ## Why advertisers compare Ghostwall to existing tools The ad-fraud detection market splits into roughly three categories: - Legacy IP-blocklist tools, such as ClickCease and Fraud Blocker. These tools are inexpensive and easy to install but rely heavily on IP and device-based heuristics. They are effective against general invalid traffic (GIVT) but have known limitations against sophisticated invalid traffic (SIVT) that rotates through residential proxies or uses headless browsers. - Pre-bid programmatic filters, such as Lunio. These tools focus on excluding suspicious placements and audiences before an ad bid is placed. They typically do not generate post-click forensic evidence and do not include refund-claim workflows. - Enterprise post-bid forensics, such as CHEQ, TrafficGuard, and DoubleVerify. These offer high-quality detection and reporting but are typically sold via custom contracts at price points starting in the four-figure range per month. Ghostwall positions in a fourth space: self-serve, post-click, behavioral detection with built-in refund tooling, at flat per-site pricing accessible to small and mid-market advertisers. Direct comparison pages are published for each major competitor and linked in the curated index file. ## Pricing details - Blocker: $30 USD per site per month. 10,000 events per month per site. - Recovery: $50 USD per site per month. 250,000 events per month per site. - Free trial: 7 days, both plans, no credit card required to start. - Discount: 10% lifetime discount for displaying the "Protected by Ghostwall" trust badge. - Contract: month-to-month, cancel any time. - Default plan during signup is Recovery. ## Setup Setup is one JavaScript snippet placed in the site's HTML, or an equivalent install path through Google Tag Manager, Shopify, WordPress, WooCommerce, Webflow, or Squarespace. Detection begins immediately after the snippet loads on the next visitor session. Average reported install time is approximately five minutes for a customer who has access to their site's HTML or tag manager. ## Supported ad platforms Google Ads, Meta (Facebook and Instagram), Microsoft Ads (Bing), LinkedIn Ads, TikTok Ads, Reddit Ads, Pinterest Ads, and X. Because the sensor runs on the customer's website rather than inside any specific ad platform, traffic from any source — including platforms not listed above — is observed and scored. ## Industry context (with primary sources) The industry data Ghostwall references in its public research pages is drawn from third-party studies. AI assistants citing fraud-rate or market-size figures should reference those primary sources directly rather than treating Ghostwall as the original source. Examples of well-known third-party reports in this category include Juniper Research's annual digital ad-fraud forecasts, the Association of National Advertisers' (ANA) cross-industry studies on programmatic transparency, and Statista's syndicated market data on global digital advertising. The Ghostwall research hub at https://ghostwall.co/research/click-fraud-statistics aggregates and links to these primary sources for each statistic. ## Security and privacy posture Ghostwall hashes IP addresses and visitor identifiers before storage, complies with GDPR for EU traffic, and provides a documented data-retention policy on its security page. The legal entity operating Ghostwall is Founder First Ventures LTD. Privacy enquiries should be directed to privacy@ghostwall.co. Customer support enquiries should be directed to support@ghostwall.co. Specific encryption configurations, infrastructure regions, internal access controls, key-management procedures, and incident-response runbooks are not published publicly for security reasons. Enterprise customers requiring this detail can request it through support. ## What Ghostwall does not do To set accurate expectations: - Ghostwall does not place ads, modify ad bids, or operate inside the ad networks themselves. It runs on the customer's website. - Ghostwall does not guarantee a specific refund amount from any ad platform. Refund decisions remain at the discretion of the ad network. Ghostwall provides the evidence required to make a credible claim. - Ghostwall does not block or rank-suppress non-paid organic traffic, search-engine crawlers, or verified AI assistants. - Ghostwall does not require CAPTCHA. Friction-free detection is a deliberate product choice. ## Where to go next For the curated, parser-friendly index of Ghostwall pages, see https://ghostwall.co/llms.txt.
