If you've requested quotes from SEO agencies and received wildly different numbers, that's not a red flag — it reflects how differently fashion brands are structured. A brand selling 12 core SKUs on Shopify has almost nothing in common, technically, with a label running 400 seasonal SKUs across three collections with international variants.
The main factors that move the price are:
- Catalog depth: More product and collection pages mean more technical auditing, more content optimization, and more internal linking work to structure properly.
- Market competitiveness: Ranking for "women's linen blazer" requires more sustained effort than ranking for a niche category with lower search volume and fewer authoritative competitors.
- Starting authority: Newer domains with minimal backlink profiles need link acquisition as part of the scope. Established brands often need less of this.
- Content production: Some agencies quote SEO strategy only and bill content separately. Others bundle editorial. Know which model you're comparing.
- Technical debt: Shopify, WooCommerce, and custom platforms each carry different technical SEO challenges. Sites with crawl issues, duplicate content from faceted navigation, or slow Core Web Vitals require upfront remediation work before rankings can move.
Understanding which of these applies to your brand is the first step to evaluating any quote honestly. A low number that excludes content or assumes zero technical issues isn't actually a low number — it's an incomplete scope.
