How We Rate E-commerce Platforms
Our scoring methodology is 100% transparent. No vendor payments influence our ratings.

Why This Matters
Your e-commerce platform directly affects your bottom line. Transaction fees eat into margins, slow checkout pages kill conversions, and poor SEO means no organic traffic. We distribute weights evenly across storefront, payments, and inventory because all three must work well — a beautiful store with bad checkout loses money the same way a fast checkout with no discoverability does.
Scoring Weights for E-commerce Platforms
Every e-commerce platform is scored across six criteria that directly impact revenue, operational efficiency, and growth potential.

How We Test E-commerce Platforms
We build a complete test store on every platform: 50 products across 5 categories, including physical goods with variants (size/color), digital downloads, and subscription items. This covers the product types most stores actually sell.
Checkout experience is tested from the customer side. We run through the full purchase flow on desktop and mobile, measuring load times, counting clicks to purchase, testing guest checkout, and evaluating the post-purchase experience including order confirmation emails and tracking.
Transaction fee analysis goes beyond the advertised rate. We calculate the true cost of processing $10,000, $50,000, and $200,000 in monthly revenue across different payment methods. We account for platform fees, payment processor fees, app subscription costs, and theme costs.
SEO testing includes checking URL structure customization, meta tag control, schema markup support, page speed scores, blog functionality, and sitemap generation. We also test how easy it is to set up proper redirects, canonical tags, and structured data without hiring a developer.
What We Don't Do
- ✗We don't accept payment from e-commerce platforms to influence scores or rankings
- ✗We don't use affiliate commission rates to decide which platform wins a comparison
- ✗We don't aggregate scores from other review sites — every score is our own original assessment
- ✗We don't test with partner accounts that have different fee structures than regular merchants
- ✗We don't ignore hidden costs like app fees, transaction surcharges, and premium theme expenses

Update Schedule
This methodology was last reviewed: April 2026. We re-evaluate our e-commerce scoring criteria quarterly. Comparisons are updated when platforms change transaction fees, launch new checkout experiences, or significantly expand their app ecosystems.
