Custom themes, product data that’s right and stock per location on the product page. Built on Shopify Online Store 2.0, with SEO and GEO for the full catalogue.

What it is
A web shop only works when it shows what’s really in stock, loads faster than the competition and ranks for the model people search for. That’s what we build on, from theme to product data.
Who it’s for
For fashion, sneaker and lifestyle retailers with several stores, a large catalogue and customers who browse online and buy in store.

How we approach it
ProcessBaseline
An audit of speed, SEO, GEO and conversion across the catalogue, so every improvement can be measured.
Design on real products
Product page, collection and homepage designed with your own catalogue, edge cases included.
Build on a test theme
Everything on a hidden theme, with Theme Check in the pipeline. Live after sign-off, with version history per release.
Keep measuring
After launch, catalogue rounds with fixed rules, reported per round.
In practice
Built by JABLFrequently asked
New theme or adapt the current one?
It depends on the base. For Collett. we built custom sections on a premium base theme; sometimes a fully custom theme is better.
Does it work with our POS?
Shopify POS works out of the box. Other POS systems we connect through their API.
What do SEO and GEO deliver?
At Collett. the SEO and GEO score rose from 41.4 to 51.7 across 220 measured pages in the first round, and online revenue almost tripled on average. We report what changed each round.
Do you build apps too?
Yes, under JABL Works we build our own Shopify apps. Custom apps for a single store are possible too.
