Before looking at price ranges, it helps to understand what you're paying for — because two agencies can both charge $1,500/month and deliver completely different scopes of work.
SEO cost for web designers is shaped by four main variables:
- Market competitiveness. If you're targeting 'web designer in Austin' or 'ecommerce website design NYC,' you're competing against established studios with years of domain authority. More competitive markets require more content, more link-building, and more time — which means higher cost.
- Service specialization. A designer who targets 'Shopify web designer for food brands' has a tighter keyword footprint to build. That's actually cheaper and faster to rank than broad terms — and converts better too.
- Starting authority. A brand-new portfolio site with 10 pages needs foundational work — technical setup, architecture, schema — before content and links make sense. An established agency site with history needs a different mix.
- Scope of deliverables. Some retainers include content writing; others don't. Some include link acquisition; others focus only on on-page. Make sure you're comparing equivalent scopes when evaluating quotes.
In our experience working with creative and design-focused businesses, the most common mistake is buying SEO based on price alone without asking what's actually being done each month. A $400/month retainer that produces two templated blog posts and a monthly report isn't SEO — it's billing.
The clearest signal that a provider is being honest: they tell you upfront which keywords they're targeting, why, and what their 90-day deliverable plan looks like.
