What Is AiDisco?
AiDisco is an AI discoverability platform and service designed to help companies become more visible, cited and recommended in platforms such as ChatGPT, Gemini, Claude and Perplexity.
Its methodology starts by mapping the company’s Prompt Universe: the complete set of questions potential customers ask AI during discovery, evaluation and decision-making.
That includes:
- Non-branded discovery questions
- Problem and use-case questions
- Category and solution questions
- “Best company” and recommendation prompts
- Competitor comparison prompts
- Objection and due-diligence questions
- High-intent buying questions
AiDisco then repeatedly tests those prompts to determine where the company appears, what AI says about it, which competitors are preferred and which sources influence the answer.
This is important because testing a few prompts once does not produce a dependable AI visibility benchmark. Answers can vary between platforms, accounts and runs. AiDisco therefore treats the Prompt Universe as an ongoing measurement system, rather than a one-off keyword list.
The resulting data informs a prioritised program across content, entity consistency, structured data, authority, citations and third-party validation.
What Is First Page Sage?
First Page Sage is an established SEO and thought-leadership marketing agency founded in 2009. Its publicly listed clients include Salesforce, Microsoft, US Bank, Logitech and Verisign, while the company reports that most of its clients are midsized businesses.
Its original strength is creating high-quality, expert-led content designed to establish category authority and generate qualified leads through organic search. Over time, First Page Sage has expanded this model into GEO, AEO and agentic search.
Its current GEO service covers areas such as:
- List creation and optimisation
- Inclusion in relevant databases
- Website authority
- Review management
- Publicising company achievements
- Monitoring social sentiment
Its AEO offering also includes audits, authoritative content, schema implementation, ongoing optimisation and performance monitoring across traditional search and answer engines.
First Page Sage should therefore not be characterised as merely a traditional SEO agency. It has developed dedicated services for AI search and recommendation environments.
The key difference is its centre of gravity: First Page Sage extends a mature SEO and thought-leadership content system into AI discovery, while AiDisco begins with AI buying prompts and answer-level measurement.
1. AI-Native Focus
The most significant difference is where each company begins.
AiDisco’s Approach
AiDisco starts with the decisions happening inside AI conversations:
- Which companies are mentioned?
- Which companies are recommended?
- What attributes are associated with each company?
- Which competitors win comparison prompts?
- What objections does AI raise?
- Which sources appear to influence the answer?
- Where is the brand absent despite being relevant?
Search rankings remain useful evidence, but they are not the final measurement. The objective is to improve how frequently and accurately the company is included in AI-generated consideration sets.
First Page Sage’s Approach
First Page Sage begins with its experience in SEO, content production, authority and digital reputation. Its GEO and AEO programs apply those capabilities to AI platforms.
This is a logical extension. AI systems frequently rely on authoritative webpages, recognised entities, reviews, lists, databases and third-party mentions when constructing answers. First Page Sage already has substantial experience creating those signals.
Its newer agentic-search service also maps an organisation’s “AI belief landscape” and develops content intended to change specific beliefs. That makes the company more AI-focused than its SEO heritage alone might suggest.
The Practical Difference
AiDisco is likely to be the better fit when AI visibility is the primary problem to solve.
First Page Sage may be the better fit when the company needs a larger, ongoing thought-leadership and organic-search program, with GEO and AEO included as part of that system.
2. Prompt Universe Coverage
AiDisco makes the Prompt Universe a central operating concept.
Rather than monitoring a short list of high-volume keywords, AiDisco maps questions across the entire buying journey. This provides a more detailed picture of how AI affects commercial discovery and evaluation.
For example, a B2B software company’s Prompt Universe might include:
- “How do companies solve this problem?”
- “What are the best tools for this use case?”
- “Which platform is best for an enterprise?”
- “Company A vs Company B”
- “What are the drawbacks of Company A?”
- “Which provider integrates with our existing stack?”
- “What should I ask during a vendor evaluation?”
These prompts have different commercial value. Appearing in an introductory definition is not equivalent to being recommended during a vendor comparison.
First Page Sage also performs research into answer engines and commercial AI queries. It has published a GEO analysis based on 11,128 commercial queries across multiple chatbots, demonstrating meaningful investment in understanding how AI systems form answers.
The distinction is that AiDisco uses the client-specific Prompt Universe as the core unit for auditing, prioritisation and ongoing measurement.
3. Measurement
Measurement is another major point of differentiation.
AiDisco’s Measurement Model
AiDisco repeatedly samples relevant prompts across AI platforms and records:
- Whether the company appears
- Where it appears in the answer
- Whether it is cited or directly recommended
- Which competitors appear
- What attributes are associated with each company
- Which sources support the answer
- How results change over time
This supports several related metrics:
- Share of Answer: How often the company appears across relevant AI answers.
- Share of Buyer Answer: How often it appears in commercially important consideration and decision prompts.
- AI Narrative Intelligence: What AI says about the company, not just whether it appears.
- Competitive White Space: Valuable prompts, attributes and topics where competitors currently have stronger visibility.
AiDisco distinguishes these metrics from broad AI Share of Voice because frequency alone does not reveal whether AI is positioning a company positively, accurately or at the right stage of the buying journey.
Its AI visibility measurement framework therefore reports presence and narrative separately.
First Page Sage’s Measurement Model
First Page Sage says its AEO programs monitor performance across traditional search and answer engines and connect that performance with conversion data. Its agentic-search offering also assesses the beliefs held by AI systems and measures whether content changes them.
That is a meaningful measurement capability, particularly for organisations that want AI visibility connected to a broader organic-search and lead-generation program.
However, buyers should ask First Page Sage how its measurements are applied to their individual Prompt Universe:
- How many prompts are monitored?
- How are prompts selected and weighted?
- How often are they retested?
- Are comparison and buying prompts reported separately?
- Is narrative sentiment separated from simple mentions?
- Can results be segmented by AI platform?
These questions should also be asked of AiDisco or any other GEO provider. AI visibility metrics are still developing, and two agencies may use similar labels for materially different methodologies.
4. Content Model
Both companies create content, but the logic behind content production differs.
AiDisco’s Content Model
AiDisco uses prompt, narrative and citation data to identify what evidence is missing.
Recommended work may include:
- Direct answer pages
- Comparison pages
- Use-case content
- Original research
- Product and methodology pages
- Case studies
- Statistics pages
- Definition and category pages
- FAQ structures
- Entity and schema improvements
- Third-party citation and authority initiatives
The goal is not simply to publish more. It is to create the smallest set of credible assets needed to close specific visibility, evidence and narrative gaps.
First Page Sage’s Content Model
First Page Sage’s heritage is in consistent, expert-led thought-leadership publishing. That can be particularly valuable in industries where commercial authority is built over a long period through research, educational content and executive expertise.
Its content model is likely to suit companies that:
- Need a dependable publishing operation
- Want to grow traditional organic search alongside AI visibility
- Have executives or subject-matter experts who can contribute insights
- Need a broad library of educational content
- Want content connected to lead generation
The trade-off is that buyers should ensure the publishing cadence is directly connected to AI prompt and citation gaps—not only keyword opportunities.
5. Authority and Third-Party Citations
Neither company treats onsite content as sufficient by itself.
First Page Sage explicitly includes reviews, database inclusion, list placement, social sentiment and achievement publicisation in its GEO model. These activities can strengthen the external evidence AI systems encounter when researching a company.
AiDisco also evaluates third-party sources and identifies which publications, databases, directories, research pages and comparison articles appear to influence AI answers. These findings become part of the implementation roadmap.
The difference is largely analytical:
- First Page Sage brings an established authority-building and publicisation capability.
- AiDisco begins by identifying which external sources influence the client’s specific Prompt Universe.
For companies with little independent coverage, First Page Sage’s broader thought-leadership and publicisation infrastructure may be attractive.
For companies that already have authority but are missing from specific AI answers, AiDisco’s narrower prompt-to-source analysis may be more efficient.
6. Public Proof and Track Record
First Page Sage has the stronger public operating history.
The company says it has worked in SEO and thought leadership for more than 15 years. Its company profile lists recognised clients and an extensive body of original research. That history reduces perceived vendor risk, particularly for larger organisations looking for an established content and search partner.
Its visibility across category discussions is also an advantage. A company that is repeatedly discussed, cited and associated with a service category has stronger entity recognition than a newer entrant.
AiDisco is newer and has a smaller public proof library.
Its published Smart Outsourcing Solution case study reports movement from minimal AI discovery to AI citations, referral traffic and inbound meetings. The full methodology and limitation are disclosed in AiDisco’s AI SEO case study.
The fair conclusion is:
- First Page Sage currently has greater breadth of public proof and a longer client history.
- AiDisco’s published proof is narrower but more directly tied to its AI-native measurement methodology.
Buyers should request relevant references from both companies, ideally involving a similar industry, sales model and level of market authority.
7. Pricing Signals
The available pricing information is not directly comparable.
AiDisco publicly lists the following starting points:
- AI Visibility Audit: From $2,500
- Implementation: Generally $5,000–$25,000+
- Ongoing programs: Custom scope
The final cost depends on Prompt Universe size, number of AI platforms, content requirements, technical work, authority gaps and measurement frequency. AiDisco provides additional context in its AI SEO pricing guide.
First Page Sage publishes a broader GEO market breakdown of approximately:
- $2,000–$3,000 per month for smaller programs
- $4,000–$7,000 per month for mid-tier programs
- $8,000–$12,000 per month for larger programs
These figures are presented as market tiers in its GEO cost analysis, not as a guaranteed quote for a First Page Sage engagement.
Buyers should therefore compare actual proposals using the same scope:
- Number of prompts monitored
- AI platforms covered
- Testing frequency
- Number and type of content deliverables
- Technical implementation
- Third-party authority work
- Reporting and attribution
- Internal team support
- Minimum engagement term
A lower monthly price may cover a much narrower Prompt Universe or exclude implementation work.
Who Should Choose AiDisco?
AiDisco is likely to be the better fit if:
- AI visibility is a strategic priority rather than an addition to an SEO program.
- You need to know how AI describes your company and competitors.
- You want discovery, comparison and buying prompts measured separately.
- You need a client-specific Prompt Universe rather than a small generic prompt list.
- Your company already produces content but does not know which AI visibility gaps to address.
- You want to prioritise content based on citations, competitive narratives and recommendation gaps.
- You need an audit or focused implementation project before committing to a large ongoing program.
Who Should Choose First Page Sage?
First Page Sage is likely to be the better fit if:
- You want an established SEO and thought-leadership agency.
- Organic search remains as important as AI visibility.
- You need a consistent, expert-led publishing operation.
- You value a long operating history and recognised client portfolio.
- Your company needs broader authority building, achievement publicisation and reputation support.
- You prefer to consolidate SEO, content, AEO and GEO with one provider.
- You have the internal experts and budget required to sustain a substantial thought-leadership program.
Trade-Offs to Consider
AiDisco Trade-Offs
AiDisco has a shorter public track record and fewer publicly available case studies than First Page Sage.
Its specialised model may also be narrower than what a company needs if the actual requirement is a high-volume, long-term SEO and thought-leadership publishing program.
First Page Sage Trade-Offs
First Page Sage’s AI services are built on top of a broader SEO and content model. That is a strength for integrated programs, but companies should confirm that their engagement will be governed by AI answer data and buying prompts—not predominantly by traditional keyword rankings.
Its long track record also does not automatically mean it is the best fit for every AI visibility problem. Buyers should evaluate the specific team, methodology, deliverables and reporting offered in the proposed engagement.
Questions to Ask Both Agencies
Before making a decision, ask each provider:
- How will you build our Prompt Universe?
- How many prompts and AI platforms will you monitor?
- How often will you retest prompts?
- How do you account for variation between AI responses?
- Do you separate discovery prompts from comparison and buying prompts?
- How do you measure what AI says about us, not just whether we appear?
- Can you identify which sources influence AI answers?
- How will findings determine the content we produce?
- What third-party authority work is included?
- How do you connect AI visibility with qualified traffic, pipeline or revenue?
- Which parts of implementation will your team perform?
- Can you show results from a company with similar market conditions?
The quality and specificity of the answers will be more useful than any provider’s category label.
Frequently Asked Questions
Is AiDisco Better Than First Page Sage?
Neither company is universally better. AiDisco is more specialised around AI answer visibility and Prompt Universe measurement. First Page Sage has a longer history and a broader thought-leadership SEO operation.
Is First Page Sage a Traditional SEO Agency?
Its heritage is in SEO and thought-leadership marketing, but its current offering also includes GEO, AEO and agentic-search optimisation. It should be evaluated as an integrated search and content agency rather than an SEO-only provider.
Which Agency Has More Experience?
First Page Sage has the longer public operating history. It was founded in 2009 and lists recognised clients across B2B and B2C industries.
Which Agency Has the More AI-Native Methodology?
AiDisco’s methodology is more explicitly organised around AI prompts, answers, narratives, citations and recommendations. First Page Sage applies its established content, authority and search capabilities to AI discovery.
Can Both Agencies Support Traditional SEO?
Yes, although traditional SEO occupies a different role in each model. It is a core heritage and capability for First Page Sage. For AiDisco, SEO supports the technical accessibility, authority and content clarity required for AI discoverability.
How Much Do AiDisco and First Page Sage Cost?
AiDisco lists audits from $2,500 and implementation programs generally ranging from $5,000 to $25,000 or more. First Page Sage publishes general GEO market ranges, but buyers need a direct proposal to determine its actual engagement cost.
What Is the Best Way to Compare GEO Agencies?
Give each agency the same representative set of discovery, evaluation, comparison and buying prompts. Ask how it would measure current visibility, identify influential sources, prioritise actions and demonstrate improvement over repeated tests.
