What Is the SEO Funnel? Stages, Keywords and How to Build One

TL;DR

An SEO funnel is a content and keyword strategy that matches pages on your site to each stage of the buyer’s journey: awareness (top of funnel), consideration (middle of funnel) and decision (bottom of funnel). Top-of-funnel pages answer questions and bring new visitors, middle-of-funnel pages help people compare options, and bottom-of-funnel pages turn ready-to-buy searches into leads and sales. AI search now answers many top-of-funnel questions directly, so the funnel also needs to make your brand visible inside ChatGPT, Gemini and Google AI Overviews.

Key takeaways

• Three stages: awareness (TOFU), consideration (MOFU) and decision (BOFU).
  
• Each stage has its own search intent: informational, commercial investigation and transactional.
  
• Map every important page to one stage and one main keyword, so pages do not compete with each other.
  
• Link the stages together: guides should lead to comparisons, and comparisons to service, category or product pages.
  
• Measure each stage differently: impressions and new users at the top, engaged sessions and assisted conversions in the middle, leads and revenue at the bottom.
  
• AI search compresses the top of the funnel: being cited in AI answers is now part of awareness.

What is an SEO funnel?

An SEO funnel is a way to plan SEO content around the steps people take before they buy. Instead of chasing traffic for any keyword, you choose keywords and pages for each stage of the journey, then connect them so visitors can move from learning to comparing to buying.

SEO funnel vs marketing and sales funnel: a marketing or sales funnel covers every channel, including ads, email and sales calls. The SEO funnel is the organic search part of it: the pages people find in Google and AI search at each stage.

What are the stages of the SEO funnel?

The SEO funnel has three main stages. Each one matches a different search intent, content type and set of KPIs.

Top of funnel (TOFU): awareness

At this stage, people are learning. They search for definitions, causes and how-to answers. Your goal is to be the best source on the topic, so visitors remember your brand. Write clear answers first, use question-based headings and link to related middle-of-funnel pages.

Middle of funnel (MOFU): consideration

Here people already know their problem and compare solutions. They search for “best”, “vs”, “examples”, “reviews” and “checklist”. This is where case studies with real numbers, honest comparisons and detailed guides build trust. Every MOFU page should have a clear next step toward a service, category or product page.

Bottom of funnel (BOFU): decision

At the bottom, people are ready to act. Queries include “services”, “pricing”, “near me”, “buy” or a brand name. These pages need strong on-page SEO, fast load times, proof such as reviews and results, and a clear call to action. BOFU keywords usually have lower search volume but the highest conversion rate.

How does AI search change the SEO funnel?

AI search tools now answer many top-of-funnel questions directly. A user can ask ChatGPT or read a Google AI Overview, learn the basics and get a shortlist of providers without visiting any website. This changes the funnel in three ways:

1. Awareness happens inside AI answers. If your brand is cited or recommended there, you enter the buyer’s shortlist even without a click.
   
2. Fewer but warmer visits. Visitors who click through from AI answers often already know what they want and land closer to the middle or bottom of the funnel.
   
3. Traffic alone no longer shows SEO success. You also need to track AI mentions, citations and branded search growth.

That is why we combine SEO with GEO (Generative Engine Optimization). Read more in our guide to GEO vs SEO.

How to build an SEO funnel: step by step

1. Define your buyer journey. Write down the questions customers ask before they buy, from the first problem to the final decision.
   
2. Research keywords for each stage. Group keywords by intent: informational for TOFU, comparison for MOFU and transactional for BOFU.
   
3. Audit your existing pages. Map each page to one stage and one main keyword, and find gaps and pages that compete with each other. A full SEO audit is a good starting point.
   
4. Start from the bottom. Make sure service, category and product pages are optimized first, because they bring revenue fastest.
   
5. Add middle-of-funnel content. Publish comparisons, case studies and checklists that lead to your BOFU pages.
   
6. Build top-of-funnel content. Answer the questions your audience asks, in a format AI tools can quote: direct answers, tables and clear definitions.
   
7. Connect the stages with internal links. Link TOFU guides to MOFU pages and MOFU pages to BOFU pages with descriptive anchor text.
   
8. Track and improve. Measure each stage separately and update pages that lose rankings, clicks or conversions.

SEO funnel example

Here is a simplified example of an SEO funnel for an online swimwear store:

For a real ecommerce swimwear brand, this kind of structure combined with GEO work helped reach 49.7K organic clicks and grow AI responses mentioning the brand from 118 to 461.
How do you measure SEO funnel performance?

Track each stage with its own metrics in Google Search Console and Google Analytics 4:

• TOFU: impressions, clicks and new users on informational pages, plus how often AI tools cite your content.
  
• MOFU: engaged sessions, pages per session, returning users, newsletter or lead magnet sign-ups and assisted conversions.
  
• BOFU: form submissions, calls, sales, conversion rate and revenue from organic search.

Common SEO funnel mistakes

• Only targeting top-of-funnel keywords: lots of traffic, but few leads.
  
• Only targeting bottom-of-funnel keywords: few pages that rank, because there is no content to build authority.
  
• No internal links between stages: visitors read a guide and leave.
  
• Several pages for the same keyword: they compete with each other and none ranks well.
  
• Measuring only traffic: you cannot see which stage loses visitors.
  
• Ignoring AI search: your competitors become the default answer at the awareness stage.

FAQ: SEO funnel

What is a funnel in SEO?

A funnel in SEO is a strategy that matches keywords and pages to the stages of the buyer’s journey: awareness, consideration and decision. It helps your site attract new visitors, build trust and convert ready-to-buy searches into customers.

What are the stages of the SEO funnel?

The three main stages are top of funnel (awareness), middle of funnel (consideration) and bottom of funnel (decision). Some models add a post-purchase stage for retention and repeat customers.

At what stage of the funnel does SEO sit?

SEO works at every stage. Informational content attracts people at the top, comparison content supports the middle, and optimized service, category and product pages capture buyers at the bottom.

What is the difference between an SEO funnel and a sales funnel?

A sales funnel covers all channels and steps before a purchase, including ads, email and sales calls. An SEO funnel is the organic search part of it: the content people find in Google and AI search at each stage.

Which funnel stage should I focus on first?

Start with the bottom of the funnel, because those pages bring leads and sales fastest. Then add middle-of-funnel content that supports them, and build top-of-funnel content to grow awareness over time.
