Before comparing agency quotes, it helps to understand the variables that make one software company's SEO program cost twice as much as another's — even when both look similar on the surface.
Keyword Competition
Ranking for "project management software" competes with companies spending millions on content and links annually. Ranking for "resource scheduling software for architecture firms" is a narrower fight. The more competitive the primary keyword, the more content, authority, and time the program requires — which translates directly into budget.
Content Volume and Type
Software buyers research extensively before buying. A typical SEO program for a SaaS company involves comparison pages, use-case landing pages, integration pages, and long-form educational content. Each piece costs time to produce well. A lean program might produce four to six pieces per month; an aggressive one twenty or more. Content production is often the single largest line item.
Technical Complexity
Modern SaaS products built on JavaScript frameworks, behind login walls, or with large product-generated URL structures often need significant technical SEO work before content investment pays off. If your platform generates thousands of thin or duplicate URLs, that has to be resolved first. Technical remediation is front-loaded cost — typically highest in months one through three, then tapering.
Link Acquisition
Organic rankings in competitive software categories require domain authority, and authority comes from links. Whether you earn those through digital PR, content partnerships, or direct outreach, link acquisition adds cost. Some agencies bundle it; others scope it separately. Clarify this upfront.
In-House vs. Fully Outsourced
If your team handles content production and the agency handles strategy and technical work, your agency spend drops considerably. If you're outsourcing everything, budget accordingly. In our experience working with software companies, hybrid models often produce the best cost-per-outcome ratio when internal marketing bandwidth exists.
