JLPG Link Explained: How the Deep-Link and Attribution Layer Actually Works

JLPG Link is the piece of infrastructure sitting between a tap on an ad and the screen a user finally sees inside an app. It does not write campaigns, and it does not buy media. It routes, matches, and reports. Teams that treat it as plumbing usually get it working in an afternoon. Teams that treat it as a marketing dashboard tend to spend three weeks arguing about attribution numbers that were never going to agree in the first place.

The problem it solves is boring to describe and expensive to ignore. A shopper taps a banner for a pair of running shoes, does not have the retailer's app installed, gets pushed to the App Store, installs, opens the app, and lands on a generic home screen with a search bar. Industry benchmarks put that drop-off somewhere between 40 and 70 percent depending on category. JLPG Link closes that gap with deferred deep linking, which is a technical way of saying the app remembers what the person wanted before they ever installed it.

The routing logic runs in roughly 12 milliseconds on a warm edge node. When a click arrives, JLPG Link reads the user agent, OS version, screen dimensions, IP-derived region, and any click identifiers already attached to the session. If the app is present on the device, an Apple Universal Link or Android App Link fires and opens the exact product page, playlist, or promo screen. If the app is absent, the request goes to the correct storefront, and a fingerprint token rides along with a short time-to-live, typically 15 to 30 minutes. First open after install, the SDK hands that token back, and the user lands on the shoes.

Attribution is where the arguments start. JLPG Link supports deterministic matching through IDFA and GAID when the user has granted tracking permission, and falls back to probabilistic device fingerprinting when they have not. On iOS specifically, opt-in rates for app tracking transparency hover in the 20 to 35 percent range for most consumer apps, so the fingerprint path carries far more traffic than people expect. Default attribution windows are 7 days for clicks and 1 day for impressions, configurable down to a 1-hour click window for high-frequency categories like ride-hailing or food delivery. Server-to-server postbacks push install and in-app event data to networks within about 2 seconds, which matters when a media buyer is optimizing against a 15-minute-old signal.

What the dashboard actually gives you

The reporting layer organizes everything around the click ID, which is a surprisingly useful unit of analysis. You can pull cohort retention by source, revenue per install by creative, and time-to-first-purchase by country without exporting a single CSV. Forty-plus network integrations ship out of the box, including Meta, Google Ads, TikTok, Apple Search Ads, Unity Ads, and AppLovin, each with prebuilt templates so you are not hand-rolling postback parameters at 11 p.m. before a launch. Custom networks connect through a generic S2S endpoint with macro support for click ID, campaign ID, and publisher sub-ID.

SDKs exist for iOS, Android, React Native, Flutter, Unity, and Cordova. A bare-bones integration is about six lines of code for initialization plus one call to register the deep-link handler. Web-to-app flows use a JavaScript tag that adds roughly 9 KB gzipped, which is small enough that most performance audits will not flag it.

Pricing runs in three published tiers. The free plan covers 10,000 tracked clicks per month with a 30-day data retention window, useful for validating an integration but not for production. Starter sits at 49 dollars per month for 50,000 attributed installs and 12-month retention. Growth is 249 dollars per month for 500,000 installs, adds custom attribution windows, and unlocks raw data exports. Enterprise pricing starts near 1,800 dollars per month with a 99.99 percent uptime commitment, dedicated redirect domains, and a named support contact with a 1-hour response target on priority tickets.

Where it breaks down

Fingerprinting accuracy degrades on iOS 17 and later when Lockdown Mode is enabled, and there is no workaround for that beyond accepting the loss and leaning on deterministic identifiers where consent exists. Deduplication errors show up when the same user converts through two networks inside the attribution window; the platform resolves this by last-click by default, which is a policy choice, not a technical truth, and it will annoy someone on your team no matter which way it is configured. Link rot is a real operational risk too. A campaign that ran two years ago and still has live creative pointing at a deprecated redirect domain will quietly send traffic to a 404. Auditing redirect domains quarterly takes twenty minutes and prevents a genuinely bad Monday.

One-link-per-campaign is another habit worth breaking early. Packing multiple destinations into a single link means every downstream report blurs three variables together. Create a separate JLPG Link for each audience, creative angle, and destination combination, and let the reporting layer do the aggregation. The teams that get the most value out of it are usually the unglamorous ones: subscription apps running tight payback windows, mid-size e-commerce shops with 200 to 2,000 SKUs, and mobile studios testing five creatives a week across three networks.

Set it up correctly once, with named conventions and a documented redirect domain, and JLPG Link disappears into the background where it belongs. The click still happens on someone else's platform. What you control is what happens in the 12 milliseconds afterward, and that is the part that shows up in the revenue line.
