Frequently asked questions

What ad platforms does ZelTracker support?

ZelTracker works with any paid traffic source including Google Ads (Search, Display, Performance Max), Facebook Ads, Instagram Ads, and TikTok Ads. Any click that lands on your website will be tracked and scored.

How does the bot scoring work?

Each session is analyzed using 50+ signals including browser fingerprinting, behavioral patterns, Cloudflare Turnstile verification, datacenter IP detection, and threat intelligence feeds. Sessions score 0-24 (Human), 25-74 (Suspicious), 75+ (Bot).

Will it slow down my website?

No. The tracking script is lightweight (under 15KB) and loads asynchronously. It does not block page rendering or affect Core Web Vitals. The Turnstile verification runs invisibly in the background.

Does it work with WordPress?

Yes. Just paste the script tag in your theme's header or use a plugin like "Insert Headers and Footers". ZelTracker is also compatible with caching plugins like Autoptimize and Breeze.

How can I use the reports to improve my campaigns?

ZelTracker provides detailed invalid traffic reports with click ID tracking that you can export as CSV. Use this data to optimize your campaigns, identify low-quality traffic sources, and export IP exclusion lists to protect your ad budget going forward.

What payment methods do you accept?

We accept all major credit cards and PayPal through our payment partner LemonSqueezy. You can manage your subscription, update payment methods, and download invoices from the billing portal in your account settings.
