Questions & Answers

As answered by people managing JavaScript.com and AdSentry.online.

Who are some of the biggest customers of your product?

AdSentry.online's answer:

  • Direct-to-consumer (DTC) e-commerce brands
  • Boutique performance marketing agencies
  • Independent media buyers running Google and Meta ads

What makes your product unique?

AdSentry.online's answer:

Unlike generic uptime monitors that only check HTTP 200 OK status codes, AdSentry analyzes live landing pages specifically for paid advertising. It traces multi-hop redirect chains to verify tracking parameters (UTM, gclid, fbclid) survive into analytics, and scans HTML & JSON-LD schema to detect out-of-stock items before daily ad spend burns on dead clicks.

Why should a person choose your product over its competitors?

AdSentry.online's answer:

Traditional monitors like UptimeRobot or Pingdom report "healthy" even when a store redirect silently drops tracking tags or a product sells out at 2 AM. AdSentry detects ad-specific attribution loss and disabled buy buttons without requiring any code installation or tracking scripts.

How would you describe the primary audience of your product?

AdSentry.online's answer:

PPC media buyers, performance marketing agencies, and direct-to-consumer (DTC) e-commerce brands running Google Ads and Meta Ads campaigns.

What's the story behind your product?

AdSentry.online's answer:

After seeing ad campaigns burn budget on landing pages where promo redirects silently stripped tracking tags or advertised products went out of stock, AdSentry was built to automate ad landing page QA and alert teams on Slack before spend is wasted.

Which are the primary technologies used for building your product?

AdSentry.online's answer:

Next.js, TypeScript, Serverless HTML & DOM inspection engine, JSON-LD Schema parser, Supabase, Tailwind CSS and Stripe.
