Sabbir's story
In his own words
-
Before SEO
Before SEO, I ran retail operations in Bangladesh. That's where I learned to judge work by what it does to the sales numbers.

2018: My own money on the line
In 2018 I started building affiliate websites with no budget. For five years I ran a group of niche sites: keyword research at midnight, content plans on weekends, and testing titles, layouts and links to see what made people click and buy.
When it's your own money, you stop guessing and start measuring. In 2022 alone, my sites sent 185,819 clicks to Amazon. Amazon shipped 3,364 items worth $91,537 from those visits.

2023: The floor fell out
Amazon paid me a few percent of every sale. In 2023 my commissions dropped across several categories, and sites that had paid for years stopped being worth the work. I couldn't control Amazon's rates. What I kept was the skill: bringing buyers from Google to a product page.

2024 and 2025: Other people's stores
In 2024 I started working on Shopify and WooCommerce stores that wanted growth they could measure in orders. In 2025 I did SEO work at a US agency. The results from that work belong to the agency's clients and are covered by an NDA, so I can't publish them here.

2026: CheckoutCurve
In 2026 I started working independently as a Shopify SEO consultant for stores in the US and the UK. Kulsum and I started CheckoutCurve together, and both case studies on this site come from that work. I lead the SEO work with Kulsum and our developer, and Kulsum makes sure you always know what was done, what's next and what it means for your sales. There's no account manager passing messages to someone you've never met.
Kulsum Akter, SEO executive
Kulsum works on every project with Sabbir. She does keyword research, fixes page titles and descriptions, and prepares your monthly reports. She's run client communication since the start of 2026, so she's the person you'll hear from most. She's a Top Rated freelancer on Upwork, where our UK client left a 5-star review.
You run your store. My job is to make sure SEO never becomes one more thing you have to chase.
What this means for your store
- You talk to the people doing the work.
- You see what your biggest problems cost you, in dollars.
- You get a fixed price before any work starts.
- Every number we show you has its source: the date range, where the traffic came from and how sales were counted.
- You own everything we change. It's all documented, so your store never depends on us to keep running.
