Frequently asked questions

A B2B SaaS brand ranks #3 on Google for “project management software.” Their Google Search Console shows 18,000 impressions per month. Their sales team asks a simple question in a strategy meeting: what does ChatGPT say when a buyer asks which project management tool to choose? They type it in. Their brand doesn’t appear. Three competitors do, all of them cited by name with specific reasons. The traffic is still coming from Google. But the buying decision is being shaped somewhere else, before the first click is made.

This is the gap keyword research in 2026 has to close. The process of finding the right keywords hasn’t become irrelevant; it has expanded. A keyword strategy that only optimises for Google impressions now leaves your brand invisible at the moment buyers are actually forming their shortlists. The six steps below cover both layers: what it takes to rank, and what it takes to get cited.

Why keyword research changed in 2026

Keyword research in 2026 has to account for a second discovery layer that didn’t exist at scale five years ago: AI-generated answers. Google AI Overviews now appear on a significant portion of searches; ChatGPT, Perplexity, and Claude answer millions of buying-stage questions daily. These platforms don’t rank a list of ten results; they synthesise one response and cite a handful of sources. If your content isn’t structured to be that source, the ranking you fought for produces fewer outcomes than it used to.

The practical change this creates for keyword research is twofold. First, question-form queries (“which CRM is best for B2B SaaS companies?”, “how do I choose a project management tool for a remote team?”) now carry a different weight to short-tail keywords. These are the queries AI tools answer verbatim. A brand whose content directly and fully answers these questions gets cited. A brand whose content is optimised for “CRM software” impressions alone often doesn’t.

Second, topical depth now signals credibility to AI systems in a way that isolated keyword rankings don’t. A site with a pillar page on B2B CRM software, eight cluster articles covering specific subtopics, and FAQ content built around exact buyer questions is read by AI as a credible expert source. A site with one CRM landing page, however well-optimised, is read as a vendor promoting itself. The keyword research process now needs to build toward the former architecture. For a deeper look at how this works, see our guide on how to build topical authority so AI tools recommend your brand.

Step 1: Brainstorm your core topic clusters

Start with topic clusters, not individual keywords. A topic cluster is the full problem space your buyer inhabits: every question they might ask, every comparison they might make, every piece of information they need before deciding to engage you. Brainstorming clusters first gives your keyword research a structure that serves both Google rankings and AI citability.

For a B2B SaaS brand selling project management software, “project management software” is a keyword. “How remote teams choose and implement project management tools” is a cluster. The distinction matters because a cluster generates 15 to 20 keyword targets naturally, each one more specific than the last, and together they cover the full range of questions a buyer asks at different stages of their research. AI tools cite from exactly this kind of breadth.

Start by writing down 5 to 8 core clusters for your business. Each one should describe a problem your buyer has, not a product you sell. Bring in a second perspective: a sales rep, a customer success manager, someone who hears real buyer language. The terms they use are closer to what buyers actually type into search and speak into AI tools than the terminology on your product page.

Each cluster becomes the seed for Step 2: you’ll use tools to expand each one into a full keyword list, then filter for intent and citability in Steps 3 and 4.

Step 2: Use tools to expand your keyword universe

Once you have your topic clusters, keyword research tools convert them into specific, measurable keyword targets. The core tools haven’t changed: Google Keyword Planner, Ahrefs, and Semrush are still the workhorses. What has changed is the additional layer of question-discovery tools you now need alongside them.

Use Google Keyword Planner for estimated search volume and cost-per-click data, which gives you a sense of commercial intent. Ahrefs and Semrush add keyword difficulty scores, SERP feature analysis (which keywords trigger an AI Overview or a featured snippet), and competitor gap analysis: the keywords your competitors rank for that you don’t yet target. For established brands competing in mid-to-high difficulty categories, focus on keywords with difficulty scores under 60 as entry points, then build toward harder terms as authority grows.

The 2026 additions to your toolkit are two sources most keyword strategies still ignore. First, Google’s People Also Ask boxes. These surface the specific question-form queries Google users ask about your topic, pulled directly from real searches. They are a direct signal of what AI tools will answer. Scrape these for every cluster and add them to your keyword list as a separate question-form column. Second, use ChatGPT or Perplexity itself as a keyword discovery tool: type your cluster topic in as a question and note what follow-up questions the AI asks or suggests. These are the exact queries where AI citation is active.

Step 3: Identify question-form keywords

Question-form keywords are the single most important category to pull out of your expanded list, because they are the queries AI tools answer directly and cite sources for. A page structured around “What is the best project management software for remote teams?” gets cited in ChatGPT responses. A page targeting “project management software” gets an impression in Google. Both matter; they serve different discovery moments.

Question-form keywords share a small set of opening structures: “how do I…”, “what is the best…”, “which [X] is right for…”, “how does [X] work”, “what’s the difference between [X] and [Y]”. The last of those, comparison questions, are particularly high-value for AI citability: when a buyer asks Perplexity to compare two products or approaches, Perplexity needs a source that directly answers the comparison. Brands that have published that comparison get cited. Brands that haven’t are invisible on that query, regardless of their domain authority.

Sort your question-form keywords into a separate tab in your keyword tracker and treat them as a distinct content brief type. Each one maps to a piece of content built specifically for AI citability: a question-form heading, a direct answer capsule at the top, and 600 to 1,000 words of supporting detail that demonstrates genuine expertise on the topic. These aren’t thin FAQ pages; they are full-depth cluster articles structured to be the best answer to that question on the web.

Step 4: Map search intent (and AI answer intent)

Search intent is the reason behind a query: what the person actually wants to find. In 2026, keyword strategy needs to map five intent types rather than four. The four traditional types still hold; the fifth is specific to AI-mediated search and requires different content to serve it.

Step 5: Map keywords to content types

Every keyword on your list should map to a specific content type. Putting the wrong keyword on the wrong content type is one of the most common structural errors in SEO: a transactional keyword buried inside a 2,000-word educational article doesn’t convert; an informational keyword on a product page doesn’t rank. The mapping matters as much as the keyword selection itself.

The three content types that serve both Google and AI visibility are pillar pages, cluster articles, and FAQ pages. Pillar pages target high-volume, broad keywords with moderate commercial intent. They cover the full topic (“what is keyword research”, “what is SEO”) in 2,500 or more words and link to every cluster article in their topic area. Cluster articles target specific subtopics (“how to do keyword research for B2B SaaS”, “what is search intent in SEO”) with 1,000 to 1,500 words of genuine depth and link back to the pillar. FAQ pages target question-form keywords with direct, structured answers, each 150 to 300 words, in a format AI tools can quote verbatim.

When you map your keyword list to these three types, the overall content plan becomes clear. Pillar keywords drive the architecture; cluster keywords fill the topic coverage; FAQ keywords address the specific buyer questions that AI tools answer daily. A keyword list that covers all three is a keyword strategy. A keyword list that only covers the first category is an SEO rankings plan with no AI citability layer. Map accordingly, and see the Shout Digital SEO service page for how we build this architecture for clients across retail, B2B SaaS, and professional services.

Step 6: Local, national, and AI-global targeting

Geographic targeting in keyword strategy now has a third dimension that didn’t exist at meaningful scale before 2024: AI-global. Local and national targeting are still necessary for Google visibility. But your content is also being read by AI tools whose users are based anywhere in the world, and those tools don’t filter by geography when they summarise and cite your content.

For Australian businesses targeting local customers, geo-modified keywords remain essential: “SEO agency Melbourne”, “keyword research consultant Sydney”, “B2B marketing Brisbane”. These drive Google rankings in local pack results and map packs, and they signal geographic relevance for Australian AI users asking location-specific questions. Don’t strip these out in favour of broader terms.

For national campaigns, the pattern shifts toward service-plus-category combinations without geo-modifiers: “Australian SEO agency”, “B2B SaaS marketing Australia”, “ecommerce SEO strategy”. These compete in broader national SERPs and get picked up by AI tools answering Australian-market queries from users anywhere on the platform.

AI-global targeting is the new consideration. A Perplexity user in London or Singapore asking “what are the best SEO strategies for ecommerce brands?” will get an answer that may cite Australian content if that content is the most comprehensive, most directly structured response available. AI tools don’t apply geographic filters to citations the way Google applies them to organic results. Your content competes globally for AI citations. This means the way you write matters as much as what you write: answer-first structure, jargon-free clarity, and question-form headings make your content citable by AI users regardless of where they’re searching from.

How Shout Digital approaches keyword strategy for GEO and SEO together

Shout Digital is a Melbourne-based digital marketing agency that builds keyword strategy to serve both Google search visibility and AI citation share simultaneously. In 15 years of managing SEO and GEO campaigns for established Australian brands, including Repco, Baby Bunting, and The Wiggles, we have found that the most durable keyword strategies are the ones built around topic clusters, question-form content, and intent mapping across all five intent types. Zero penalties across 15 years and countless algorithm updates.

What separates a Shout keyword strategy from a standard SEO brief is the GEO layer applied from the start. We don’t build a keyword list for Google and then retrofit AI optimisation later. The question-form keywords, the intent mapping, and the content type assignments are all planned with both discovery surfaces in mind: the Google SERP where your buyer starts, and the ChatGPT or Perplexity response where they’re forming their shortlist.

“We track AI citation share monthly across ChatGPT, Gemini, Perplexity, and Claude for every client. Keyword research is the upstream input. Citation share is the downstream output. The brands that improve fastest are the ones whose keyword strategy was built to generate citable content from day one.”

Shout Digital SEO and GEO strategy practice, Melbourne

Our Opportunity Analysis identifies the keyword gaps where your brand is currently invisible in AI responses but where competitors are being cited. We then build the content cluster architecture to close those gaps, starting with the highest-value question-form keywords in your category. The result is a keyword strategy that compounds: each new piece of cluster content reinforces the authority of every piece that came before it, improving both Google rankings and AI citation rates across the same keyword set.
