We do SEO for ecommerce brands from Perth, and we work inside the store, not next to it. Fridgy Australia, one of the clients we name publicly, is a Shopify store. We are comfortable in a theme, in Liquid, in metafields and in the Search Console coverage report at the same time, because ecommerce SEO problems usually live in all three at once.
An e-commerce brand that went from near-invisible on category keywords to 37 keywords at position one. Organic purchases up 285%.
Position one in Australia across the AS/NZS 3760 cluster, off an architecture rebuild rather than more content.
Ecommerce SEO problems rarely sit in one place. They live in the theme, the catalogue structure and the crawl at the same time, so that is where we start.
The checks we run on a store first:
Every one of those is a template fix rather than a recommendation, which is why we do the SEO and the theme work together.

Product pages are where we find the most broken markup:
The result is conflicting prices on the same page, and a rating value that Google will not use because it is self serving markup on your own site rather than genuine collected reviews.
We audit what is actually being emitted, remove the duplicates at the theme level, and make sure one clean Product object carries the correct offer price, currency, availability and variant data straight from the Liquid objects so it can never drift out of sync with what the customer sees. Breadcrumbs and Organisation markup get the same treatment.
SEO with us starts from $1,000 including GST per four week cycle, quoted to scope. We bill every four weeks rather than monthly, so cycles line up with the work rather than with the calendar.
We handle the SEO and the build work ourselves, so the person auditing your store is the person editing the theme. That matters on ecommerce more than anywhere else, because the fix for most of the problems described above is a change to a Liquid template, not a recommendation emailed to whoever maintains your theme.
If you would rather we quoted the build and the SEO together, we do that too.
Send us your store URL and what is not working. Whether that is product pages that never rank or traffic that never turns into orders, we will come back with specifics, not a generic pitch. If you would rather talk it through, call us.
