Our enterprise SEO agency comparison guide
Search Engine Optimisation (SEO) for enterprises is categorically different from SEO for small to medium-sized businesses. While a small to medium-sized business could have hundreds of web pages, enterprises typically have thousands, if not millions. Standard SEO companies often aren’t built for this level of complexity, which is why you need a specialised enterprise agency.
To help you find the SEO company that best fits your business, we’ve created this guide. By the end, you'll have a clear, evidence-based view of the top SEO agencies in 2026, enabling you to make your decision with confidence.

The importance of AI search and GEO for enterprises
AI search is here to stay, and as an enterprise business, you can’t afford to ignore it. Research has shown that 37% of consumers already start searches with AI instead of Google, and this figure is expected to increase in the coming years as AI advances. If your website isn’t optimised to appear in these AI-generated results, you risk becoming invisible to a growing number of potential customers.
A GEO agency will understand the process of optimising your site to appear in AI platforms like ChatGPT, Claude, Perplexity, and Google’s AI overview. AI platforms like these are designed to source information from brands with authority and credibility. For this reason, establishing your brand through trusted references is a crucial feature of GEO. Digital PR is important, but an AiPR™ agency plays a vital role in this process, helping your business earn quality mentions and signals that boost visibility within AI-generated answers.
To find out more about the rise of generative AI and what it means for your brand, take a look at our GEO playbook.
Questions to ask your enterprise SEO agency
How do you manage SEO at scale for enterprise organisations with millions of pages?
Make sure your prospective enterprise SEO agency has the knowledge and capabilities to manage websites with a large volume of pages and a complex site structure.
How are you approaching GEO and AI search visibility for enterprise brands in 2026?
As AI overviews and LLM-generated answers are capturing a high volume of enterprise search queries, your agency needs to go beyond and also have a strong GEO strategy.
What kind of reporting and transparency can we expect?
Enterprises need detailed reporting focused on ROI. The most effective agencies won't just track keyword rankings or traffic; they'll relate that SEO performance directly back to your enterprise business outcomes, like revenue and customer acquisition costs.
How will your SEO strategy drive measurable growth for our enterprise over the next three to five years?
This question shifts the conversation away from short-term rankings and towards long-term value.
