A ranked list of what to fix, with the draft ready to approve.
Proofsource turns what it measures into a gap register: 33 gap types in 8 groups, each with a stable ID and a severity. It ranks your open gaps by expected lift against effort, then drafts each fix from your own facts for a person to approve.

| ID | Gap | Severity | In-house |
|---|---|---|---|
| E1 | robots.txt does not explicitly allow the major AI crawlers. | Critical | Yes |
| B2 | Review-site About text is stale, wrong, or describes a different business. | Critical | Yes |
| E2 | Key category content renders client-side and is absent from initial HTML. | High | Yes |
| D1 | No “X vs [brand]” page exists for any tracked competitor. | High | Yes |
| C1 | Absent from most of the listicles that accept submissions. | High | No |
Every gap has an ID, a severity and a fix.
The register checks the same 33 gap types for every brand, from citation supply and review sites to machine access and the entity graph. IDs never change, so E2 means the same thing in every report and you can watch a gap close over time.
- Eight groups: citations, reviews, listicles, comparisons, machine access, entity graph, community, measurement
- Severity from critical to low
- Marked when a gap can be fixed without a third party
Fix the gap with the most lift for the least effort first.
Each open gap is scored by how many tracked answers it is likely to move and how much work it takes. A one-hour crawler change that unblocks two engines beats a month of new content. The list re-ranks as answers change.
- Expected lift beside every fix
- Effort beside every fix
- Re-ranked as new answers arrive
| Fix | Expected lift | Effort | Rank |
|---|---|---|---|
| E1 · Allow GPTBot and ClaudeBot | High | 1 hour | 1 |
| D1 · Publish Acme vs Rival page | High | 2 days | 2 |
| B2 · Correct the G2 About text | Medium | 30 min | 3 |
| C1 · Pitch 4 open listicles | Medium | 1 week | 4 |
Drafts written from your facts, approved by a person.
For fixes that need words, such as a comparison page, a corrected profile or an FAQ, Proofsource drafts the text from your confirmed facts and the answers it captured. Every draft lists what it is grounded in. Nothing is published until someone on your team approves it.
- Grounded in your confirmed facts and captured answers
- Sources listed under every draft
- Human approval before anything ships
Acme has a free plan for up to 3 users and paid plans per seat. Rival starts at its Team tier…
See whether the fix moved the answers.
The questions a fix targets keep being asked after it ships. Proofsource compares mention rate before and after, each with its 95% range, so you can tell a real gain from a lucky week.
- Before and after on the targeted questions
- 95% ranges on both sides
- Wins and losses both stay on the record
Mention rate on the 6 comparison questions this fix targets. The ranges do not overlap, so the change is not noise.

Questions buyers ask
How does Proofsource decide what to fix first?
Each open gap is scored by its expected lift, meaning how many tracked answers it is likely to change, against the effort it takes. The list is sorted by that ratio and re-ranked as new answers arrive.
What is the gap register?
The gap register is a fixed list of 33 gap types in 8 groups: citation supply, review sites, listicles and directories, comparison content, machine access, entity graph, community and proof, and freshness and measurement. Each gap has a stable ID and a severity, and Proofsource marks which ones apply to your brand.
Does Proofsource write content for me?
Proofsource drafts the text a fix needs, such as a comparison page or a corrected profile description, using only your confirmed facts and the answers it captured. A person on your team approves, edits or rejects every draft. Nothing is published automatically.
What does fixable without a third party mean?
Some gaps you can close yourself, such as a robots.txt rule or a missing comparison page. Others need someone else, such as a listicle editor or a review platform. Proofsource marks each gap so you can start with the ones in your control.
How do I know a fix worked?
Proofsource keeps asking the questions a fix targets and compares mention rate before and after, with a 95% range on each, so a real gain is distinguishable from normal variation.
Can I try Proofsource for free?
Yes. The free trial is 2 free scans, today and tomorrow: 25 buyer questions on ChatGPT, Perplexity, Claude and Google AI Overviews. No card. After the second scan, scanning pauses and your answers stay in your account.
How much does Proofsource cost?
Custom plans start from $64 per brand per month. Final price confirmed at launch. Every plan includes the four core engines; you choose how many questions and brands to track.
