Focus categories: supplements, wellness, pets and beverage. ## Process 1. **Audit**: Analytics, session recordings and funnel data. Find where the money actually leaks, not where it looks ugly. 2. **Hypothesize**: Rank fixes by expected revenue impact. The biggest leak gets the first test, always. 3. **Test**: A/B test against the control. Winners have numbers. Opinions do not ship. 4. **Scale**: Roll winners sitewide, feed learnings into the next round. Compounding, not one-off wins. Step 5 is step 1 again: the next leak is already ranked. ## Live work (39 pages) ### Listicles (9) - [Serene Herbs: Gut relief listicle](https://sereneherbs.com/pages/end-embarrassing-gas-and-constipation-for-good) - [Serene Herbs: 8 Reasons listicle](https://sereneherbs.com/pages/8-reasons-why-americans) - [Kind Patches: De-puff listicle](https://kindpatches.com/pages/unpufflp) - [Snibbs: Work shoe listicle](https://snibbs.co/pages/hos-orbit-rw-listicle) - [Froya Organics: Anti-aging listicle](https://froyaorganics.com/pages/10-reason-why-aging) - [Pretty Boy: Skincare listicle](https://www.yoprettyboy.com/pages/10rw-v1) - [Nutrotonic: Shilajit listicle](https://nutrotonic.com/pages/shilajit-v1) - [Physician's Choice: Fiber Gummies listicle](https://physicianschoice.com/pages/Fiber-Gummies) - [Physician's Choice: Fiber Gummies listicle v2](https://physicianschoice.com/pages/fiber-gummies-v2) ### Advertorials (5) - [Rennora Beauty: Beauty advertorial](https://try.rennorabeauty.com/fadvert-v25) - [Zephta: 2+4 free offer advertorial](https://secure.zephta.com/2-4-Free-SHP#next-step) - [Kiwi: Car coating advertorial](https://m.kiwient.com/funnel/news-car-coating-spray-for-shine---protection) - [Pets Are Kids Too: IVDD advertorial](https://www.petsarekidstoo.com/pages/mc-ivdd-lp6) - [Quasi: Collagen advertorial](https://officialquasi.com/pages/adv-v1) ### Websites and PDPs (25) - [Gratsi: Store](https://gratsi.com) - [AP Labs: Store](https://aplabs.co/) - [Darviny: Store](https://justdarviny.com) - [Free Soul: Store](https://freesoul.com) - [Innerstellar Pet: Store](https://innerstellarpet.com/) - [Customised Cuff: Store](https://customisedcuff.co/) - [Serene Herbs: Store](https://sereneherbs.com/) - [Healthletic: Store](https://healthletic.io/) - [Nutrotonic: Shilajit Gummies PDP](https://nutrotonic.com/products/authentic-himalayan-shilajit-gummies) - [Physician's Choice: Easy Mix Fiber landing](https://physicianschoice.com/pages/easy-mix-fiber-landing) - [Physician's Choice: Fiber Gummies landing](https://physicianschoice.com/pages/fiber-gummies-landing) - [Tru Niagen: Store](https://www.truniagen.com/) - [EnergyBits: Store](https://energybits.com/) - [Trulean: Store](https://www.trulean.com/) - [ViDrate: Store](https://www.vidrate.com/) - [Organic Traditions: Store](https://organictraditions.com/) - [Essential Stacks: Store](https://essentialstacks.com/) - [PYM: Store](https://youcanpym.com/) - [Electric Cloud: Store](https://www.drinkelectriccloud.com/) - [Electric Cloud: EC71 landing](https://www.drinkelectriccloud.com/pages/ec71) - [HairLove: Store](https://hairlove.com) - [Doc & Glo: Healthy Hair Habit PDP](https://docandglo.com/products/healthy-hair-habit-nutraceutical-hair-support-supplement) - [Healthletic: BPC-157 PDP](https://healthletic.io/products/body-protection-compound-bpc-157) - [Orlo Nutrition: Store](https://orlonutrition.com) - [Eyetamins: Blue Blocker PDP](https://eyetamins.co/products/blue-blocker) ## Writing - [It Was Never a Bad Agency.

Hamid Chakir is a senior conversion rate optimization (CRO) and growth strategist for direct-to-consumer (DTC) brands, based in Waseca, Minnesota. Over 7+ years he has worked on more than 200 DTC brands in supplements, wellness, pets and beverage, including Physician's Choice, where he runs a sitewide testing program across 580K monthly sessions. ### What does a CRO consultant do for a DTC brand? A CRO consultant finds where a store loses buyers between the ad click and the checkout, then fixes it with tested changes instead of opinions. Hamid covers the full conversion layer: listicles and advertorials for paid traffic, product pages (PDPs) and landing pages, offer architecture, subscription flows, and the A/B testing program that ties them together. ### What results has Hamid Chakir delivered? Physician's Choice reached a 3.95% store conversion rate with about 50% subscription adoption. A full funnel rebuild for Natural Rems lifted conversion rate by 40% and average order value by 25%. A listicle and landing page program for Serene Herbs lifted conversion rate by 30% and average order value by 20%. His peak store conversion rate is 5.57%, and his best single A/B test took conversion from 1.18% to 5.88%. ### What is the difference between a listicle and an advertorial? Both are pre-sell pages that sit between a paid ad and the product page. A listicle catches a cold click from a Meta or TikTok ad and warms it into a buyer with scannable reasons before the PDP loads. An advertorial is story-first: one reader, one problem, one mechanism, then the product, in an editorial format that keeps skeptical, ad-blind traffic reading all the way to the offer. ### How does Hamid run a CRO program? The same four-step loop on every account. Audit: analytics, session recordings and funnel data to find where the money leaks. Hypothesize: rank fixes by expected revenue impact. Test: A/B test each change against the control. Scale: roll winners sitewide and feed the learnings into the next round. No redesigns on faith. ### Which brands has Hamid Chakir worked with? Brands include Physician's Choice, Tru Niagen, Free Soul, Gratsi, EnergyBits, Snibbs, Organic Traditions, PYM, Trulean, Essential Stacks, Kind Patches, Serene Herbs, Natural Rems, Quasi, Electric Cloud, ViDrate, Pretty Boy, Better Wild, Bump Energy, Spacemilk, Ceelike, Mucho, Boba Nutrition, Myota, Miils, Modern Dose and Check My Body Health. The proof wall on this page links to 39 live pages he built, rebuilt or ran the testing program on. ### How do I work with Hamid? Email chakircro@gmail.com with what your store converts at today. Hamid replies within 24 hours with what he would test first, before you pay anything.

It opens with a numbered "reasons why" headline aimed at one group of buyers, backs each reason with proof, keeps the offer in view, and hands a warmed reader to the PDP. Seven of the nine live listicles below use that headline pattern. - [Advertorial examples: 5 live DTC advertorials, broken down](https://portfolio.hamidchakir.com/guides/advertorial-examples/): A good DTC advertorial is a story-first article that sells. It follows one reader, one problem and one mechanism before it names the product, and it borrows editorial cues (a masthead, byline, date and first-person voice) so cold, ad-blind traffic keeps reading to the offer. The five live examples below, from a hair serum to a car coating spray, show that sequence in different wrappers. - [Listicle vs advertorial: which pre-sell page should cold Meta and TikTok traffic land on?](https://portfolio.hamidchakir.com/guides/listicle-vs-advertorial/): Send cold traffic that already accepts the problem to a listicle, and cold traffic that doubts it can be fixed to an advertorial. A listicle gives scannable reasons to choose your product. An advertorial walks one reader through one problem and one mechanism first. Then split-test your pick against the client's control, because the numbers pick the winner. - [DTC store and product page examples: what 25 live pages do above the fold](https://portfolio.hamidchakir.com/guides/dtc-product-page-examples/): Converting DTC stores and product pages use the first screen to answer three questions: what is this, why should I trust it, and what is the offer. Across the 25 live pages below, that means a plain benefit headline, a rating line, a trust or press strip, and on product pages a buy box with bundle tiers and a subscribe and save option. - [How a CRO testing program runs: audit, hypothesize, test, scale](https://portfolio.hamidchakir.com/guides/cro-testing-process/): A CRO testing program runs as a loop of four steps. Audit the funnel to find where the money leaks, rank the fixes by expected revenue impact, A/B test the biggest one against the control, then roll the winner sitewide and feed what you learned into the next round. Step five is step one again. No redesigns on faith. - [Conversion rate vs revenue per visitor: how to read an A/B test before you ship it](https://portfolio.hamidchakir.com/guides/conversion-rate-vs-revenue-per-visitor/): Read it on the metric that pays you: conversion rate and revenue per visitor side by side, in relative and absolute terms, before anything ships. Conversion rate counts buyers. Revenue per visitor, conversion rate times average order value, counts money, so it is the number to ship on whenever the variant can change what people spend. - [What does a CRO consultant do for a DTC brand, and when do you need one?](https://portfolio.hamidchakir.com/guides/what-does-a-cro-consultant-do/): A CRO consultant finds where a store loses buyers between the ad click and the checkout, then fixes it with tested changes instead of opinions. For a DTC brand that covers the full conversion layer: pre-sell pages, product and landing pages, offer architecture, subscription flows and the A/B testing program. You need one when ad spend keeps rising and the page does not change. ## Case studies Written by Hamid Chakir in the first person ("I" = Hamid). - Index: https://portfolio.hamidchakir.com/case-studies/ - [Physician's Choice: a sitewide CRO testing program at 3.95% store conversion and ~50% subscription adoption](https://portfolio.hamidchakir.com/case-studies/physicians-choice/): Physician's Choice is a gut health supplement brand, and one of the biggest supplement brands in the US. As senior CRO, I work on its sitewide testing program across 580K monthly sessions: PDPs, landing pages, offer and subscription flow. The portfolio ledger lists a 3.95% store conversion rate and ~50% subscription adoption. Both are program levels, not before and after lifts. - [Serene Herbs: +30% conversion rate and +20% AOV from a listicle, landing page and PDP program](https://portfolio.hamidchakir.com/case-studies/serene-herbs/): Serene Herbs sells plant-based herbal formulas, led by liquid bitters tonics. I ran a listicle and landing page program plus PDP optimization for its paid traffic. My portfolio ledger records the result at brand level: conversion rate up 30% and average order value up 20%. Three live pages from that work are shown below, described from their screenshots. - [Natural Rems: a full funnel rebuild that lifted conversion rate 40% and average order value 25%](https://portfolio.hamidchakir.com/case-studies/natural-rems/): For Natural Rems, a DTC brand, I rebuilt the funnel end to end: a PDP restructure, the offer architecture and the post-click flow. My portfolio ledger records a 40% lift in conversion rate and a 25% lift in average order value, both at brand level. No Natural Rems pages are on the proof wall, so this case study covers scope, method and what the two numbers mean together. - [$41.19M in 365 days, up 162%: what a testing system does when the conversion rate barely moves](https://portfolio.hamidchakir.com/case-studies/dtc-store-41m/): One DTC store, kept anonymous, did $41.19M in the last 365 days, up 162% year over year, while its conversion rate slipped 4%. Sessions grew 71% and orders 114%. In my essay I credit the growth to a testing system running across every traffic angle, every offer and every bundle. This case study shows the raw Shopify receipt, tile by tile. - [Paid House Agency: CRO, landing pages and product pages across multiple client brands, in the CEO's own words](https://portfolio.hamidchakir.com/case-studies/paid-house-agency/): Paid House Agency is a boutique agency working with seven and eight figure ecommerce brands. I worked with them on CRO across multiple client brands: landing pages and product pages, with oversight of both design and development. No figures are published for this work. The result on record is George's on-camera review: big conversion rate increases, better paid ads performance and no development hiccups.
