The Definitive SEO, AEO, and GEO Guide for Software

SEO, AEO, and GEO are three layers of one search program. SEO earns the ranking. AEO earns the citation. GEO earns the mention. They share a content engine, a site, and a set of entity facts, which is exactly why running them as three separate initiatives produces three conflicting roadmaps.

This guide is the operating system we use at Momentence for software companies. It is organized as five checklists you can actually execute: foundations, answer coverage, entity and structured data, off-page corpus work, and measurement. Every item is an artifact somebody can point at when it is done, not a principle to agree with.

The three layers, defined

Each discipline has a distinct surface, a distinct unit of success, and a distinct set of levers. Getting these boundaries right is the difference between a coherent program and a pile of tactics.

• SEO is the practice of earning position in a ranked results page. Surface: the SERP. Unit of success: ranking, then qualified click. Levers: crawlability, site architecture, topical depth, internal linking, page experience, external links.
• AEO is the practice of structuring content so a model can lift a clean answer from your page and attribute it to you. Surface: a specific answer. Unit of success: the citation. Levers: answer-first structure, question-shaped headings, JSON-LD, coverage breadth, server-rendered HTML.
• GEO is the practice of shaping the wider corpus a generative model draws on. Surface: the generated text itself. Unit of success: representation, meaning inclusion plus accuracy. Levers: third-party placement, review and roundup presence, consistent entity facts everywhere your brand appears.

If you want the boundary between the last two in more depth, read GEO vs AEO. For how answer optimization relates to classic search, read AEO vs SEO.

Checklist 1: the shared technical foundation

The foundation is the set of conditions under which any of the three layers can work at all. A page that cannot be crawled, rendered without JavaScript, or resolved to a known entity fails SEO, AEO, and GEO simultaneously. Fix this first, every time.

• Server-rendered HTML for every indexable page, with content present in the raw response
• One canonical URL per page, self-referencing, with no competing near-duplicates
• Sitemap that lists only indexable, canonical, 200-status URLs, referenced in robots.txt
• robots.txt that explicitly allows the AI crawlers you want (GPTBot, PerplexityBot, ClaudeBot, Google-Extended) rather than blocking them by accident
• llms.txt at the root that summarizes what the company does, the services, pricing posture, and the canonical URLs for each
• Core Web Vitals in the green on mobile for template pages, not just the homepage
• No orphan pages: every important page reachable within three clicks of the homepage
• Descriptive internal anchor text, since both crawlers and models use it as context
• Unique title under 60 characters and meta description under 160 on every route
• Correct HTTP status codes: no soft 404s, no chains longer than one redirect

A useful test: disable JavaScript and load your five highest-intent pages. If the main answer is missing, nothing downstream in this guide will work.

Checklist 2: answer coverage

Answer coverage is having one citable page for every question a buyer asks on the way to a decision. This is the single highest-leverage work in the program, because it serves SEO and AEO at the same time.

Build the question inventory first. Pull from sales call recordings, support tickets, the questions people actually type, and the follow-up prompts assistants suggest in your category. Then map each question to a page and a stage.

• Category definition pages: what the thing is, who it is for, how it works
• Comparison pages: X vs Y, and honest alternatives pages that include competitors
• Pricing and cost pages that state real numbers rather than deferring to a call
• Implementation and integration pages that answer "will this work with our stack"
• Objection pages: security, compliance, migration, switching cost, contract terms
• Use case and industry pages that mirror how buyers self-identify

Then format each page so a model can lift it cleanly:

• A one-sentence definitional answer in the first 100 words, quotable verbatim
• Question-shaped H2s that match real phrasing, not clever internal naming
• A TL;DR or key-takeaways block near the top
• Short declarative paragraphs, two to four sentences, that survive being quoted alone
• At least one list, table, or worked example per page
• A visible FAQ block with four or more questions, mirrored in JSON-LD
• Dates and figures that are current, with no stale year references
• Zero unverifiable claims: no invented statistics, no fabricated proof

The last item matters more than it sounds. Models penalize inconsistency, and buyers punish it harder. Full pricing transparency is part of why our pricing page publishes numbers instead of a form.

Checklist 3: entity and structured data

Entity work is making a machine able to answer "who is this company, what do they sell, and can I trust these facts" without guessing. This is where most software sites are weakest, and it is the cheapest gap to close. Our AI Search Readiness Benchmark 2026 found that 38 percent of software homepages carry no JSON-LD at all and only 8 percent publish FAQPage schema, so this checklist is where most of the available ground is.

• Organization schema with a stable @id, legal name, logo, founding date, and sameAs links to every profile you control
• Service or Product schema on each offer page, with service type and description matching the visible copy
• FAQPage schema wherever a visible FAQ exists, and nowhere else
• Article schema on guides with publish and modified dates
• BreadcrumbList on every non-root page
• Identical company description, category language, and product names across the site, your profiles, and any directory listing
• One canonical spelling of every product name, with no legacy names lingering in old pages
• Structured data that mirrors visible content exactly, since mismatch is treated as manipulation

Run a single audit question across your properties: if five sources describe your category five different ways, a model will pick one at random. Consistency is the entire trick.

Checklist 4: off-page corpus work (GEO)

GEO is off-domain work that changes what a model has read about you. You do not control these sources, which is why this layer runs on a longer clock and needs a steady cadence rather than a launch.

• Identify the 20 to 40 sources that assistants actually cite in your category, by running the prompt set and recording domains
• Get accurate presence on the review and directory sources that appear repeatedly
• Earn inclusion in the roundups and "best tools for X" pages models pull shortlists from
• Publish original data or a benchmark other people have a reason to cite
• Correct outdated third-party descriptions of your product, pricing, and category
• Place expert commentary where practitioners in your category already publish
• Keep founder and executive profiles consistent with the company entity facts
• Re-audit quarterly, because model outputs drift as sources refresh

Naming competitors in comparison content is part of this layer, not a risk to avoid. Buyers already run those comparisons in an assistant. Being factual and fair, and disclosing your own bias, is what earns the citation.

Checklist 5: measurement

Measurement fails when one dashboard is asked to prove three different things. Use three scorecards with three owners and one shared review.

• SEO: non-brand impressions and clicks, ranking distribution on a fixed keyword set, indexed page count vs submitted, organic-sourced pipeline and closed revenue
• AEO: citation share on a stable prompt set, which of your pages gets cited, referral sessions from assistant domains, and coverage percentage of your question inventory
• GEO: share of voice across the prompt set (appearances, cited or not), description accuracy scored pass or fail per fact, and competitive shortlist position
• Shared: a single monthly review where all three read against pipeline, so nobody optimizes a metric that does not move revenue

Build the prompt set once and freeze it. Fifty to a hundred prompts across category, comparison, pricing, and objection intents is enough. Changing the prompts every month is the most common way teams convince themselves they are winning.

A worked 90-day sequence

Sequence matters more than effort. This is the order we run for a software company starting from a thin site.

1. Days 1 to 30: full foundation checklist, entity and structured data pass, robots and llms.txt, prompt set built and baselined. Nothing published yet.
2. Days 31 to 60: question inventory mapped, the eight highest-intent answer pages shipped (category, pricing, two comparisons, two objections, two use cases), internal linking rebuilt around them.
3. Days 61 to 90: coverage expansion, first GEO placements and third-party corrections, second prompt-set run compared against baseline, first honest read on which layer is moving.

By day 90 you should see AEO movement and early SEO signal. GEO share of voice usually starts shifting in months four to six. That cadence is why we hold a flat six-month minimum on engagements.

Common mistakes

• Treating GEO as a rebrand of SEO. Different lever, different owner, different report. Merging them hides the fact that neither is being run.
• Publishing volume before fixing foundations. Fifty pages that do not render server-side are fifty invisible pages.
• Schema that does not match the page. FAQ markup with no visible FAQ, or a service description that contradicts the copy, gets discounted.
• Hiding pricing. Pricing questions are among the highest-intent prompts in every software category. If you do not answer them, a third party will, and they will be wrong.
• Moving the prompt set. If the benchmark changes, the trend line is fiction.
• No single owner. Three vendors on three layers produces three roadmaps and inconsistent entity facts, which actively damages GEO.
• Chasing citations without a destination. A mention with nothing credible to land on converts nobody.

What to do next

Pick one thing: run the foundation checklist against your five highest-intent pages this week. Most teams find three items that are silently blocking everything else. Then build the prompt set and baseline it before you publish anything, so you have a real before.

If you would rather have one team run all three layers on one roadmap, that is what our SEO, AEO, and GEO programs do together, with published pricing and a six-month minimum so the work has time to compound.
