SEO pricing isn't arbitrary — it maps to the amount of skilled work required each month. For app development companies specifically, three variables determine where your investment lands on the range.
1. Keyword Competition in Your Market
Ranking for "mobile app development company" is a fundamentally different challenge than ranking for "fintech app developers Chicago." Broad national terms require sustained content production and link acquisition over 12–18 months. Niche or geography-specific terms can show movement in four to six months with less ongoing investment. The more competitive the keyword set, the more the work costs.
2. The State of Your Website
If your site has technical issues — slow Core Web Vitals, crawl errors, thin service pages, duplicate content from CMS templating — those need to be addressed before content or links will move the needle. Technical remediation is often front-loaded cost. A site in good technical shape costs less to grow because you're not paying to fix problems first.
3. Scope of Deliverables
SEO is not one service. It's a combination of technical work, content production, and authority building (link acquisition, digital PR, mentions). Agencies that bundle all three charge more than those that focus on one. Understanding which of the three you need most is the most important budget decision you'll make before signing a contract.
Practical note: In our experience working with technology companies, founders often underinvest in content and overinvest in technical audits they don't implement. The highest-use spend for most app development companies at the early stage is well-researched service and use-case content — not another crawl report.
