AI Search Visibility

Keyword and Prompt Research for AI Search: The BID Method

Direct Answer

AI-era research needs two connected maps: a keyword map for repeated Google demand and a prompt map for the conversational situations in which AI systems choose sources and brands. Build the keyword list with seeds and modifiers, vet it with Business potential, Intent, and Difficulty, then apply an AI filter that asks whether the result still earns a click or should be targeted for visibility inside the answer.

The final roadmap should have three queues: click-first SEO opportunities, mention-and-citation AEO opportunities, and hybrid topics that need both. Exact-match prompt chasing is too brittle. Build evidence and content around the full topic, audience, task, constraints, and decision stage.

Credit: This guide is based on Ahrefs' AEO Course lesson with Sam Oh and the supplied transcript. The three-queue roadmap, prompt matrix, scorecard, and evidence rules below are editorial additions. Start with the preceding brand gap analysis lesson if the brand's missing topics and entities are not yet mapped.

1. Build a Scalable Keyword List

Begin with broad seeds that describe the market, product, service, or customer problem. Combine them with modifiers that reveal the content or action a searcher expects. AI can help brainstorm this vocabulary, but its suggestions are hypotheses until a keyword database, Search Console, customer evidence, or a live result page validates them.

Modifier familyExamplesLikely need
Learnhow, why, guide, tutorial, examplesExplanation or instruction
Comparebest, top, versus, alternatives, reviewShortlist or decision support
Actcalculator, checker, generator, tool, template, finder, planner, makerComplete a task
Buyprice, cost, quote, demo, trial, near meCommercial or transactional action
Fitfor agencies, for beginners, for teams, for a locationAudience-specific suitability
Problemfix, error, not working, improve, reduce, replaceResolve a specific failure or constraint

In Ahrefs, enter the seeds in Keywords Explorer, open Matching Terms, and use the Include filter for relevant modifiers. Export the useful candidates with their country, volume, traffic potential, intent, Keyword Difficulty, and current result-page features. Keep the seed and modifier that produced each idea so the research can be repeated.

2. Apply the BID Method

TestDecision questionEvidenceReject when
B: Business potentialIf this page wins, can it naturally help the right customer and support an offer?Product fit, buyer stage, conversion path, first-party revenue or lead dataThe traffic is unrelated or the offer must be forced into the answer
I: IntentCan the site create the content type, format, and angle the result page rewards?Live SERP, dominant page type, format, freshness, local and commercial signalsThe required experience conflicts with the planned page
D: DifficultyCan this site produce a credible result and earn the authority needed to compete?Page-level referring domains, competing brands, content quality, topical depth, unique proofThe gap in authority, product, evidence, or resources is unrealistic

Ahrefs' formal Business Potential model uses a 0-3 score based on how naturally the product can be presented as the solution. Keyword Difficulty is useful, but it is only a backlink-based estimate in Ahrefs. Read the actual result page. A low score does not make weak content rank, and a high score does not make a valuable topic impossible.

A Transparent Candidate Score

Use the BID decision first. For candidates that pass, rank the work queue with an inspectable score:

Priority = business potential + intent fit + traffic or visibility potential + evidence advantage - production effort - authority gap.

Score each factor from 0 to 5 and retain the factor values. The total is a discussion aid, not an automated publishing decision.

3. Apply the AI Filter

Before approving a keyword, inspect the live result page and ask: can the AI answer fully satisfy this task? Ahrefs' 146-million-SERP study found AI Overviews on 21% of tracked keywords, including 57.9% of question queries and 46.4% of queries with seven or more words. In that dataset, 99.9% of AI Overview keywords were informational.

Those figures describe a dated dataset, not a universal rule. Search features vary by country, device, account, and time. Record the observation date and screenshot or export. Then evaluate the task:

  • Answer-complete: a concise definition or fact may produce little reason to click.
  • Answer-assisted: the summary helps, but the reader still needs detail, proof, comparison, or implementation.
  • Action-required: the reader must use a calculator, checker, generator, template, dataset, product, or service.
  • Trust-required: the decision needs firsthand evidence, independent reviews, local expertise, or current professional judgment.

Do not reject every informational topic. Some build authority, earn citations, support a product cluster, or introduce a qualified audience. The filter decides the objective and format, not merely whether a page gets published.

4. Split the Roadmap Into Three Queues

QueuePrimary outcomeGood candidatesMeasure
Click-first SEOQualified organic visits and actionsTools, templates, local services, product pages, calculators, deep comparisonsRankings, clicks, qualified sessions, conversion
Mention/citation AEOBrand inclusion and source visibility inside answersDefinitions, category questions, “best” and alternatives prompts, original statisticsMentions, citations, Share of Voice, branded demand
HybridVisibility in the answer and a valuable reason to continueResearch, detailed guides, interactive assets, product-led educationCitations plus clicks, assisted conversions, enquiries

A citation is not a recommendation, and neither guarantees a click. Ahrefs' later self-promotional content experiment found examples where a page was cited while a competitor named on that page was recommended. Report citations, brand mentions, traffic, and conversions as separate stages.

5. Find AI Mention Opportunities

In Brand Radar, add the brand and its domain, choose the relevant AI platform, and isolate responses where competitors appear but the brand does not. Filter commercial-research language such as best, top, versus, review, and alternative. Read the complete response and every cited source before adding an opportunity.

The lesson highlights listicles because Ahrefs reported that “best” lists appeared in 43.8% of ChatGPT source types and 48.9% of AI Overview sources in the cited study. That does not mean any listicle will be trusted or that self-ranking a product first is durable. Prefer independent, maintained sources and accurate inclusion. Where owned comparison content is appropriate, make selection criteria explicit and treat competitors honestly.

Citations are volatile. Ahrefs later reported that only about 54% of cited URLs carried over between consecutive AI Overview checks in a 43,000-keyword study. Save the query, platform, response, cited URL, location, and date. Re-run a fixed set rather than treating one answer as a permanent win.

6. Research Prompt Families, Not Exact Phrases

Conversational systems receive long, contextual requests that may never repeat verbatim. They can also fan one prompt into multiple retrieval queries. Build a matrix of situations around the topic:

DimensionQuestions to mapExample
AudienceWho is asking, and what do they already know?Solo consultant, agency owner, enterprise team
TaskWhat are they trying to understand, compare, choose, or do?Choose a rank tracker
ConstraintWhat limits the answer?Budget, geography, privacy, team size, integration
StageAre they learning, shortlisting, validating, or buying?First shortlist versus final vendor check
AlternativeWhat other category, workflow, or competitor could solve it?Spreadsheet versus SEO platform
EvidenceWhat proof would make the answer credible?Current pricing, tests, case study, independent review

Create representative prompts from the matrix, then track them consistently. The content plan should cover the shared subtopics and evidence the prompt family requires. Do not create dozens of near-duplicate pages for wording variations with no distinct user value.

Common questions

What is the BID method for keyword research?
BID stands for Business potential, Intent, and Difficulty. A keyword should support a real business outcome, match the type of result searchers expect, and offer a realistic path to ranking based on the competing pages and domains.
How is prompt research different from keyword research?
Keyword research groups repeated search terms with measurable demand. Prompt research maps the many conversational ways people describe a topic, audience, constraint, and decision. Because AI systems fan prompts into sub-queries, the objective is broad topic and entity coverage rather than one exact prompt.
Should a keyword be rejected when an AI Overview appears?
No. Check whether the AI answer fully resolves the task and whether clicks still have value. The topic may belong in a citation and brand-mention queue instead of a click-first SEO queue, or it may need a practical tool, template, dataset, comparison, or product experience that an answer cannot replace.
Which modifiers tend to preserve organic click value?
Action-first modifiers such as calculator, checker, generator, tool, template, finder, planner, and maker often signal that the searcher needs to use something. Validate the live result page and business fit because no modifier guarantees clicks or rankings.
