Project details

With a 99.5% accuracy, the cookie-less identification by way of browser fingerprinting is a mutatable identification system that identifies users, bots, and virtual machines. With further custom programming, the user's identifiers can be saved for years on end for continuous identification and lookup of data without a cookie.

The initial setup will save the fingerprint in the browsers local storage and also in Cookie format so it can integrate with server backend. Other features are available too like Business Name visiting, website url, network connected, geo location, and more. Take a look at the second image. Only if the ip is from a business IP will the website and organization be of the company visiting. In the residential case visitor, it will be of their connecting ISP.

Add code to push data to Zapier/Brevo John's work was excellent, and he was very responsive. Unfortunately, something changed when I paused the contract for a couple of weeks, which is my standard practice when I cannot focus on a project. When I restarted the contract, he did not respond. I allowed ample time and made several attempts to contact him. It was out of character, and I became concerned about his well-being, thinking he might have had a mishap. I still wonder why he refused to reply rather than just letting me know he didn't wish to continue, and is the reason for my less-than-5-star rating.

Conversion Audits & Behavioral Analytics | Landing Pages & Tracking

Camden, United States - 1:25 pm local time
I understand physics — but with human behavior, through how people interact with machines. I've been designing and programming marketing systems since 1997 (package design before that), and it comes down to one thing: knowing why a visitor does what they do on your page, and proving it with data instead of hunches.

Results from that approach:
• Reworked one landing page in about an hour — resequenced the headline, reviews, and layout — conversions rose roughly 1000%
• Full rewrite for an insurance company: ~600% lift
• Built an automation system that turned 90 days of staff work into an overnight process
• $200K+ earned here across 460+ jobs — clients tag me most for Reliable (106), Clear Communicator (101), Committed to Quality (100)

What I do:
• CONVERSION AUDITS — "opinions on paper." A written diagnosis of where your funnel bleeds: message match, mobile experience, trust signals, tracking integrity, traffic quality. Prioritized fixes your developer can execute without interpretation, plus a Loom walkthrough.
• LANDING PAGES — design, code, and direct-response copy from one person (certified in direct-response copywriting; Frank Kern's Inner Circle).
• TRACKING & DATA PLUMBING — GA4, Tag Manager, webhooks, Zapier/Make, HubSpot API, CRM pipelines. A client's words: "John helped me untangle an overly complicated process between my website and CRM that wasn't working properly."
• PAGE SPEED — because a 14-second mobile load kills the sale before your headline gets a chance.

The difference: I build my own marketing software — behavioral analytics that measures whether visitors actually READ each section of a page, and lead-quality scoring that flags the junk clicks quietly burning ad budgets. When you hire me, you get the operator and the toolmaker.

I price defined outcomes at flat rates, report in plain English, and move fast.

Send me your URL and I'll tell you the first two things I'd fix — before you spend a dollar.
