SEO ROI Statistics for 2026: Returns by Industry, Conversion Rates, SEO vs PPC, Timeline, and B2B Performance

In 2026, the business case for SEO is more data-rich and more contested than ever. Organic search drives 53% of all trackable website traffic according to BrightEdge, outperforming every other single digital channel. The average SEO campaign delivers 748% ROI over a three-year period according to First Page Sage’s proprietary data across hundreds of client campaigns. And 49% of marketers in a Search Engine Land poll identify organic search as the top ROI-producing digital channel, placing it well ahead of paid search at 19%, social media at 18%, and email at 14%.

At the same time, the ROI picture is becoming harder to read. Organic CTR for first-position search results dropped from 28% to 19% between 2024 and 2025, driven by the proliferation of AI Overviews, zero-click searches, and SERP features. Zero-click searches now account for 60% of all Google queries in 2025, up from 58% in 2024. And 56% of B2B marketers struggle to attribute ROI to their content marketing efforts, a measurement gap that leads to SEO teams receiving smaller budgets than PPC peers who can show conversion data more directly.

The industry-level variation in SEO ROI is striking. Real estate delivers 1,389% ROI over three years according to First Page Sage, followed by financial services at 1,031%, medical devices at 1,183%, and higher education at 994%. E-commerce SEO delivers a more modest 317% ROI but operates at a volume where that percentage represents millions in revenue. Technical SEO alone, according to the same firm, provides an average ROI of 117%. And campaigns that integrate content with link building deliver 73% stronger returns than content-only approaches.
