When you get two SEO quotes and one is $600/month and the other is $2,200/month, the difference usually isn't markup — it's scope. A few variables determine how much work is required to move a garage door company up in local search.
Market Competition
A garage door company in a mid-size city with three or four local competitors needs far less monthly content and link-building effort than one trying to rank in a major metro where national chains, large regional operators, and established independents all compete for the same keywords. Competitive markets require more sustained content output, more citation work, and more deliberate link acquisition.
Service Area Size
Single-city operators can focus authority on one set of location pages. Companies serving 10–20 surrounding towns need optimized pages for each target location — that's a bigger content build upfront and more ongoing maintenance to keep each page current and relevant.
Current Website Authority
A site that's been live for five years with some existing content and a handful of backlinks is easier to accelerate than a brand-new domain with no history. Starting authority affects how quickly Google trusts new signals, which affects how long it takes to see ranking movement.
Technical Debt
If your current site has slow load times, duplicate content, broken internal links, or schema errors, those need to be fixed before ranking work is efficient. Technical remediation is usually billed as a one-time project cost ranging from a few hundred to a few thousand dollars depending on severity — it's separate from the monthly retainer.
When you're comparing quotes, ask each provider to break down what's included for each of these four variables. A lower monthly price that excludes technical work isn't necessarily cheaper over 12 months.
