# Simms Fishing's Magento to Shopify migration: the real numbers

## The short answer

Agency Inflow published a named case study on Simms Fishing's January 2022 Magento to Shopify migration. Organic traffic was up 126% year over year roughly 10 months out. Within the first 4 months, non-brand category page traffic was up 5,642% and the non-brand keyword footprint was up 1,095%, driven by splitting consolidated category pages into narrower, more specific ones.

## Key takeaways

- Inflow's case study reports Simms Fishing's organic traffic grew 126% year over year in the roughly 10 months following its January 2022 Magento to Shopify migration.
- In the first 4 months after launch, non-brand category page traffic rose 5,642% and the non-brand keyword footprint rose 1,095%, per the agency's published figures.
- The gains are attributed mainly to splitting broad category pages, such as one combined "fishing shirts" page, into narrower pages for hoodies, T-shirts and flannels.
- Inflow frames the result as going beyond ordinary migration maintenance, crediting new content and URL structure work done alongside the platform switch.
- The case study does not publish raw session or keyword-count numbers behind the percentages, so the figures here are relative gains, not absolute traffic volumes.

Most published migration case studies report a percentage and stop there. Inflow, the agency
behind this one, at least names the client, states real launch dates and separates two different
measurement windows, which makes it possible to check what is actually being claimed. The client
is Simms Fishing, a fly fishing gear retailer, and the migration was a platform switch from
Magento to Shopify.

## What happened and when

Inflow had worked with Simms Fishing since September 2018. The site migration itself launched
between January 15 and 27, 2022. Inflow's write-up gives two separate result windows rather than
one blended number: a 4-month mark (through roughly May 2022) for the non-brand metrics, and a
roughly 10-month mark for the year-over-year organic traffic figure.

## The numbers, as Inflow states them

Organic traffic was up 126% year over year at the later measurement point. In the earlier
4-month window, non-brand category page traffic was up 5,642% and the non-brand keyword
footprint was up 1,095%. Inflow does not publish the raw session counts or keyword totals behind
any of these percentages, so what is verifiable here is the relative growth the agency reports,
not the site's actual traffic volume before or after.

## What actually drove the non-brand jump

Inflow's account credits a specific content and information-architecture change made alongside
the platform switch, not the migration by itself. The old site had consolidated categories, one
"fishing shirts" page under a URL like `/t-shirts-hoodies` covering hoodies, T-shirts and
flannels together. The new structure split that into dedicated pages, `/fishing-hoodies/`,
`/fishing-t-shirts/` and `/fishing-flannels/`, plus similar splits for hats and shoes. Each
narrower page could then rank for its own non-brand search terms instead of competing with its
siblings for one shared URL. Inflow's own framing is explicit that this went beyond migration
maintenance: "our new content work with Simms took their results beyond the expected."

## Why we care

A platform migration is usually described as a risk to be survived without traffic loss. This
case is one of the more specific published examples of a migration used as the occasion for a
structural fix, splitting overly broad category pages, that the agency credits for most of the
non-brand gain. The lesson worth taking is the mechanism, not the multiplier: 5,642% is a
relative jump from a low base on non-brand category traffic, not a number to expect on a
different site's migration. What travels is the idea that a re-platform is a legitimate moment to
also fix a URL structure that was silently capping how many search terms your category pages
could ever rank for.

## Frequently asked questions

### What platform migration did Simms Fishing go through?

Per Inflow's published case study, Simms Fishing, a fly fishing gear retailer, moved from Magento to Shopify, with the new site launching January 15 to 27, 2022.

### What were the actual results?

Inflow reports organic traffic up 126% year over year roughly 10 months after launch. In the first 4 months, non-brand category page traffic was up 5,642% and the non-brand keyword footprint was up 1,095%.

### What caused the non-brand traffic jump specifically?

Inflow's write-up credits splitting broad category pages into narrower ones, for example turning one combined "fishing shirts" page into separate pages for hoodies, T-shirts and flannels, each able to rank for its own non-brand search terms, rather than the platform switch by itself.

### Are these absolute traffic numbers or percentage changes?

Percentage changes. Inflow's case study does not publish the underlying session counts or keyword counts, so the figures here describe relative growth, not the site's actual traffic volume.
