ChatGPT recommends brands and cites pages based on six measurable factors: domain authority via Bing's TrustRank model, community corroboration from Reddit and forums, content freshness, schema markup coverage, Wikipedia-level entity presence, and conversational content structure. These are not equally weighted -- domain authority and community corroboration together explain 60% of the citation selection outcome across the 85,000-session SE Ranking study.
The most important insight for beginners is that you can improve three of the six factors without a single line of code: freshness (by updating your content dates and republishing), community corroboration (by participating in Reddit threads relevant to your topic), and conversational structure (by rewriting your section headings and opening paragraphs). These three actions collectively account for roughly 50% of the citation selection weight and require no developer involvement.
The interactive explorer below lets you click each factor, see exactly what it means at your reading level, and discover the specific implementation action that moves it. Use the priority matrix below that to identify which factor is highest-priority for your type of site.
The Six Factors That Determine ChatGPT Recommendations
Research tracking 85,000 ChatGPT Search sessions across 14 verticals identified six factors that predict whether ChatGPT cites a source or recommends a brand. The factors are not equally weighted -- domain authority and community corroboration together account for 60% of the predictive weight. Click any factor to read the full mechanism and implementation tactic for your reading level.

Factor Priority by Site Type
The six factors are not equally important for every site. A new brand's highest-ROI move is community corroboration; an established publisher's is freshness. Select your site type to see the prioritized implementation sequence.
New brand (under 2 years old) -- factor priority sequence
- 1Community corroborationCritical
Identify two subreddits where your audience is active. Post monthly with genuinely useful content that references your site as a supporting resource.
- 2Content freshnessCritical
Implement IndexNow from day one. New domains have no TrustRank -- freshness is your primary lever until editorial links accumulate.
- 3Schema markupHigh
Add FAQPage schema to every informational page immediately. Schema implementation costs nothing and multiplies citation candidates per page.
- 4Wikipedia presenceMedium
Publish original research that Wikipedia editors can cite. Brand Wikipedia pages require press coverage you likely do not have yet.
- 5Domain TrustRankLow
TrustRank takes 12 to 18 months to build meaningfully. Focus on other factors for the first year.
Signal Combination vs Citation Rate
The six factors produce compounding returns when combined. Hover each data point to see why that signal combination produces its observed citation rate.
