How should businesses set an SEO budget? Align goals first, then compare resources and returns

When setting an SEO budget, businesses should first identify which marketing goals organic search needs to support, then prioritize spending based on how important the website is to driving sales, available resources, competition, and their own return on investment. No fixed percentage works for every business; a share of revenue or the marketing budget can provide a rough starting point, but it cannot replace an assessment of conversions, closed sales, and execution requirements.

First, clarify the goal: more sales or greater brand awareness?

The Martech.org article summarized on WarriorForum recommends putting SEO in the context of overall marketing goals before setting a budget. If a business relies on organic traffic to generate more leads or sales, budget discussions should center on those KPIs. If revenue targets have already been met and the next step is to expand brand awareness, internal expectations should reflect that goal rather than retain the same sales requirements.

  • Which goals should organic search support: leads, sales, or brand awareness?
  • How much growth potential remains in organic search, and are expectations realistic?
  • How important is website traffic to revenue? An e-commerce business that depends on online sales may need to invest more in SEO than a physical store.

Factor in both available resources and market constraints

For e-commerce businesses, Seer Interactive recommends combining user research, competitive research, and on-site search data while considering seasonality, market challenges, and available resources. These factors should inform budget discussions, rather than setting a percentage first and then requiring all the work to fit within it.

For example, even when the goal is the same—increasing sales from search—different products, audiences, and market conditions may call for different approaches. When evaluating an agency, businesses should also check whether it has researched their products and competitors and is willing to explain risks and adapt to their working practices. A generic list of “best practices” alone is not enough to judge whether the investment is appropriate.

Compare SEO and paid search using your own returns

SEO and PPC budgets should not be allocated solely by traffic volume. The material recommends comparing a business’s own organic and paid traffic to see which visitors convert, which leads ultimately become sales, and what return on investment each delivers. Only if SEO actually brings in more high-quality visitors and higher returns is there a basis for considering a larger budget share, rather than assuming that SEO is always more cost-effective.

If a business prioritizes retention and brand loyalty, it can also use customer lifetime value to estimate the value of web pages, rather than measuring organic traffic solely by first purchases. However, this is an estimation method for budget planning, not a claim that every search visitor will become a long-term customer.

Competitive gaps can guide priorities, but cannot directly determine a price

When competitors actively target industry keywords, businesses can compare rankings and assess the opportunity cost of customers going to rivals to help determine whether SEO deserves higher investment priority. But the material also cautions that this answers only part of the question: knowing that competitive pressure is high does not mean the budget needed to overtake competitors has been calculated. Competitive comparisons should help establish priorities, not be presented as a guarantee that spending more will secure a win.

Business SEO budgets: perspectives from across the web

Can an SEO budget simply be set at 30% to 40% of total revenue?

This percentage should not be treated as a general rule. One forum opinion suggests that an SEO budget depends on website revenue and that 30% to 40% of total revenue is usually sufficient; another source explicitly states that there is no single formula. A percentage of revenue is, at most, a rough starting point. Whether it is appropriate still depends on the business’s reliance on website sales, marketing goals, and available resources.

Beyond costs, what resources should an SEO budget account for?

Budget planning should account for the people, expertise, and other resources needed to carry out the work, rather than merely setting a monetary amount. In 2018, a Semrush article recommended involving SEO consultants early in important relevant activities within the client’s organization or at its external agencies. This is collaboration advice, not a current platform rule, and it does not mean every company needs the same staffing structure.

Where can you start if you do not yet have a precise SEO budget figure?

You can start with a rough estimate based on a share of revenue or the digital marketing budget, then check whether the goals organic search is expected to support are realistic. If website traffic is more important to sales, a different investment share may be needed; however, a rough percentage does not establish how much is required. The estimate should then be adjusted using the business’s own marketing metrics, search potential, and available resources.
