Search Engine Optimization (SEO) is one of the highest-ROI marketing channels available today, driving long-term, compounding growth, earning traffic, leads, and revenue without ongoing ad spend. There’s no one-size-fits-all SEO budget. What a business spends on SEO depends on its growth goals, maturity, market competitiveness, and internal capabilities. It’s also critical for a business to understand SEO budget alongside other marketing budgets to ascertain which platforms are providing the best return on investment (ROI) or the best value in relation to the broader business goals and channel-specific objectives. Performance marketing encompasses a wide range of marketing platforms, including paid search. Compared to the value-add and objectives of SEO, the ROI and leads produced by those channels are considerably more visible on a balance sheet. It is crucial to differentiate SEO from traditional paid advertising channels, which many other channels fall into, when defending the SEO budget. Although it is a component of a performance marketing strategy, it does not have a direct input-output goal. In most cases, paying for consultation expertise and elements (SEO activities) that compound to create a performant organic search presence, and now, a more prominent position and visibility within genAI and large language models (LLMs). SEO is, for the most part, a longer-term strategy.
