Most SEO budgets fail because nobody itemized them first.
An agency quote of $4,000/mo sounds like one number, but it's really four: content production, link building, tools, and the management margin on top. When you break the retainer into line items, you can see exactly what you're paying for — and which parts you could run cheaper in-house or automate entirely. Businesses that itemize before they sign negotiate better and churn less.
