AEO for SaaS: We Tracked 180 B2B Category Prompts Across Four AI Engines. Here Is What Content Type Gets Cited.

AEO for SaaS works when a page exists to help a buyer choose. In RankFast’s 180-prompt study across four AI engines, competitor comparison pages were cited in 64 percent of commercial-intent prompts, pricing pages in 58 percent of cost prompts, and generic feature pages in 9 percent. Pages that only describe a product are rarely cited.

What Content Type Gets Cited Most in B2B SaaS AI Answers?

Pages built to help a buyer choose between vendors get cited far more often than pages built to describe one vendor. In the 180-prompt study, comparison pages led, pricing pages followed, and generic feature pages and category blog posts barely registered.

Content type	Cited in	Measured against
Competitor comparison pages (Fastlook vs X, best X alternatives)	64 percent	Commercial-intent prompts
Pricing transparency pages	58 percent	Cost-related prompts
Use-case pages for a named job role or ICP	41 percent	Job-to-be-done prompts
Generic feature pages	9 percent	Prompts (denominator to confirm before publish)
Blog posts on general category topics	6 percent	Prompts (denominator to confirm before publish)

Source: RankFast 180-prompt study, 9 SaaS clients, ChatGPT, Perplexity, Gemini, and Claude. The first three rows are measured against the matching prompt type, so the percentages are not directly comparable with the last two rows.

The direction matches independent work. Overthink Group’s analysis of 1,263 solution-aware B2B SaaS prompts across ChatGPT, Gemini, Perplexity, and Google AI Overviews, published in July 2026, found that “best of” and “top” listicles made up 70.8 percent of all citations (Overthink Group). That study measured share of citations rather than share of prompts, so the numbers cannot be laid side by side, but both datasets say the same thing: content that ranks options beats content that describes one.

This is the core finding for any answer engine optimization b2b saas programme. Teams that search for how to get cited in chatgpt saas are usually hoping for a technical trick. The data points to a page type instead: a buyer asks the assistant to help decide, and the assistant quotes the page that already does the deciding.

How Was the 180-Prompt Study Run?

RankFast runs a 20-prompt AI gap audit for every new AEO client before building a content plan. Across 9 SaaS clients over 6 months, those audits produced a dataset of 180 prompts, tracked on ChatGPT, Perplexity, Gemini, and Claude.

Each client’s 20 prompts covered the question types a B2B buyer actually types: best [category] for [ICP], [product] vs [competitor], how much does [category] cost, [product] pricing, [job to be done] software, and [feature] tool for [use case]. For each prompt the audit logged which brand was cited, what type of page was cited, whether the client appeared, and which competitor appeared instead.

Where this study is limited, so you can weigh it properly: 

• Nine clients is a small base, and these are clients who chose to buy AEO work, which may skew toward categories where AI answers already matter.
• Runs per prompt and per engine: [insert before publish]. The brief does not state how many times each prompt was repeated in the study, and repeat count affects how stable a citation rate is.
• AI answers change between sessions and over time. A rate measured across these 6 months is a snapshot, so treat “specific and repeatable” as a hypothesis to retest in your own category, not a settled law.

Which SaaS Prompts Are Contested and Which Are Undefended?

A contested prompt is one where two or more strong competitors already dominate the citations. An undefended prompt is one where no brand is cited consistently. Undefended prompts are where a new page has the best chance of earning a citation quickly, which makes them the first place to spend content budget in any aeo strategy saas 2026 plan.

The practical test from the manual audit: a prompt where a competitor appears in 4 of 5 runs and your brand appears in 0 of 5 is contested and currently losing. A prompt where the cited brand changes from run to run, or no brand appears at all, is a gap. Write that page first, because there is no incumbent passage to displace.

The category-level breakdown below is the part of the dataset that has to come from RankFast’s own logs. It is shown as a template so nothing is invented.

SaaS category	Prompts tracked	Contested prompts	Undefended prompts	Top-cited content type
Category 1 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 2 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 3 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 4 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 5 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 6 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 7 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 8 [insert]	20 [confirm]	[insert]	[insert]	[insert]
Category 9 [insert]	20 [confirm]	[insert]	[insert]	[insert]

Template for RankFast’s 9-category breakdown. The 20 prompts per category is derived from 180 prompts across 9 clients and assumes one category per client; confirm before publishing. Every [insert] cell needs real data from the audit logs, anonymised by vertical.

Does G2 and Capterra Presence Affect AI Citations for SaaS?

G2 and Capterra presence is strongly associated with higher citation rates in RankFast’s data, but the data cannot show that reviews cause the citations. In the study, 73 percent of B2B category prompts on ChatGPT and Perplexity cited either G2 or Capterra, directly through a link or indirectly by referencing reviews hosted there.

G2 verified review count	Citation rate across tracked category prompts
Fewer than 25 reviews	12 percent
25 to 99 reviews	[insert, not supplied in the brief]
100 or more reviews with a complete profile	41 percent

Read the table as an association. Brands with 100 or more verified reviews are usually larger, older, and mentioned in more places, so review count may be a marker of the things that earn citations rather than the cause. An independent analysis from Presenc AI, covering roughly 6,800 procurement-intent queries across ChatGPT, Gemini, Claude, and Perplexity, found a smaller gap, about 2.3 times higher citation frequency for brands with 100 or more reviews against fewer than 20, and labels its own estimates directional (Presenc AI). Presenc sells AI visibility monitoring, so it has a commercial interest in the finding, the same as RankFast does.

One more caution on the 73 percent figure. It counts prompts where at least one answer pointed to G2 or Capterra. Other studies count share of all citations, which gives much smaller numbers: Overthink Group found the G2 network accounted for 8.0 percent of citations in its sample (Overthink Group), and Omniscient Digital measured G2 at 2.09 percent of bottom-of-funnel citations in a February 2026 sample of 25,755 citations (Omniscient Digital). The denominators differ, so none of these contradict each other, but they should not be quoted as if they measure the same thing.

What follows for a SaaS team is modest and still useful: an incomplete or neglected G2 profile is a cheap gap to close, because review platforms are one of the places AI engines look when they evaluate B2B software brands. Treat it as one input to measure, not a lever with a guaranteed return.

What Page Format Earns AI Citations for B2B SaaS Most Reliably?

A self-contained answer paragraph of 40 to 60 words, placed directly under the H1 and under every H2 before any setup text, is the format that earns citations most reliably. Each paragraph has to make sense if read in isolation, because that is how an AI engine lifts it.

The second format lever in RankFast’s data is balance. Comparison pages with a balanced verdict, naming where the competitor actually wins, were cited at 2.4 times the rate of promotional comparison pages. The likely reason is that AI engines extract the passage they judge to be factually reliable, and a page that admits a competitor’s strengths reads as more reliable than one that claims to win every row. That explanation is an inference from the pattern, not something the study tested directly.

This also settles a question that confuses many teams. Vendors use answer engine optimization, AEO, and generative engine optimization saas work more or less interchangeably, and there is no agreed definition separating them (Wikipedia). In practice the job is the same: write the page an assistant will quote when a buyer is deciding, and structure it so the quotable part can stand alone.

For prompts about ai search b2b software shortlists, the assistant is usually assembling three to five vendors and a reason for each. A comparison page that states its verdict in the first 60 words gives it that reason ready-made.

How Do You Run the Prompt Audit Yourself?

Define the 20 most commercially important prompts a buyer in your category would type, then run each one five times on ChatGPT and Perplexity. That is 10 runs per prompt and 200 data points in total, and it takes a few hours the first time.

1. Write the 20 prompts. Include best [category] for [ICP], [your product] vs [competitor A], how much does [category] cost, [your product] pricing, [job to be done] software, and [feature] tool for [use case].
2. Run each prompt five times per engine in a fresh incognito session, because assistants personalise on history.
3. Log four things per run: the brand cited, the source page type, whether your brand appears, and which competitor appears instead.
4. Sort the results into contested and undefended. Contested means a competitor appears in most runs and you do not. Undefended means no brand is cited consistently.
5. Write the undefended pages first, in the format the study favours: comparison, pricing, or role-specific use case.

Once the audit is repeatable, tracking tools take over the monthly rerun. Fastlook is RankFast’s own AI-visibility product, listed here with that affiliation disclosed, and it pairs tracking with the content-brief step. Profound is the enterprise option. The original brief described Profound as data only with no content execution, but a September 2026 review says its Agents feature generates content briefs and full article drafts from what AI models are citing in a category, with the caveat that a generated draft still needs editorial and factual review (Dageno). Pricing and feature limits on all of these tools change often, so confirm current details with each vendor.

Some teams run the audit in-house for a quarter first. Others hand it to an aeo agency or a broader ai seo agency already running their search work. When you compare a saas seo agency or a b2b saas seo agency that has added aeo services to its menu, the question that separates real capability from relabelling is simple: can they show you one completed prompt audit with the contested and undefended split? Apply the same test when shortlisting the best aeo agency for a smaller account. RankFast sells AEO services, so weigh that test knowing the source.
