Search engines are where most customer journeys begin, whether someone is looking for a local dentist, comparing software, or researching a major purchase. It makes sense, then, that businesses of every size invest in optimizing for search. But how many companies use SEO, and is it truly as widespread as marketers claim? Industry surveys consistently show that a large majority of businesses with a website invest in SEO in some form, yet the depth and quality of that investment varies enormously. Understanding the landscape helps you see both the competitive pressure and the opportunity.

The Big Picture of SEO Adoption
Most marketing industry surveys over recent years report that the majority of businesses with an online presence actively invest in SEO, with many marketers ranking it among their highest-ROI channels. Adoption is highest among larger organizations, ecommerce brands, SaaS companies, and professional service firms. Among small businesses, adoption is lower but steadily growing as owners realize that customers search online before calling, visiting, or buying.
Adoption by Company Size
Enterprise companies almost universally have some form of SEO function, whether through an in-house team, an agency, or both. Mid-sized businesses often rely on agencies or a small internal marketing team that handles SEO alongside other responsibilities. Small businesses show the widest variation. Some invest heavily in local SEO and content, while others rely only on the basic optimization included in their website builder. Many small companies still have unclaimed business profiles, missing metadata, or slow websites, which creates opportunities for competitors who take SEO seriously.
Adoption by Industry
Industries with high-value customers and competitive search results tend to invest most. Legal, healthcare, finance, real estate, home services, software, and ecommerce are among the most active. In these sectors, ranking on the first page can be worth thousands of dollars in monthly revenue. Industries that rely heavily on referrals or offline sales have historically invested less, although that gap is narrowing as buying behavior shifts online across nearly every market.
Why SEO Adoption Keeps Growing
Several factors drive continued growth. Paid advertising costs keep rising, making organic traffic more attractive. Consumers trust organic results and often skip ads. Content and search visibility compound over time, delivering returns long after the initial investment. Additionally, the rise of AI-powered search experiences has made businesses realize they must optimize not just for traditional rankings but also for how AI systems understand and cite their brand, which is why many now add GEO services to their plans.
Using SEO Versus Using It Well
A company claiming to "use SEO" might simply have installed a plugin and written a few meta descriptions. That is very different from a strategic program built on keyword research, technical audits, content planning, and link building. The real competitive advantage lies in execution quality. Even in industries where nearly every competitor invests in SEO, a business that does it more thoughtfully, consistently, and technically can still win the most valuable positions.
In-House Versus Agency SEO
Companies approach SEO in different ways. Larger organizations often build internal teams for strategy and content while hiring agencies for specialized technical work or link acquisition. Smaller companies usually outsource entirely because hiring a full team is expensive. Many businesses use a hybrid model, keeping content creation internal and relying on external experts for audits, strategy, and reporting.
What This Means for Your Business
If most of your competitors already invest in SEO, not doing so means handing them the customers who search for your services every day. On the other hand, if your industry is still slow to adopt, you have an opportunity to establish authority before the market becomes crowded. Either way, the widespread use of SEO signals that organic visibility is no longer optional for businesses that want sustainable growth.
How to Get Started
Begin with a technical and content audit to understand where your site stands. Identify the keywords your customers use and map them to relevant pages. Claim and optimize your business profiles, improve page speed, and publish content that genuinely answers customer questions. Then track progress through analytics and search console data, adjusting your strategy as you learn what drives results.
Conclusion
A large and growing majority of companies use SEO, making it one of the most widely adopted digital marketing practices. However, adoption alone does not guarantee results. The businesses that win are those that treat SEO as a strategic, long-term investment and execute it with expertise. If your company is ready to compete, now is the time to build a search strategy that sets you apart.
