## ChatGPT / OpenAI |
|
6
|
|
|
7
|
**Crawler:** `GPTBot` |
|
8
|
|
|
9
|
**How it finds content:** |
|
10
|
|
|
11
|
- Training data (periodic, large-scale ingestion) |
|
12
|
- Browsing tool (real-time web search when users ask current questions) |
|
13
|
|
|
14
|
- When browsing, ChatGPT uses Bing's search index as a starting point, then fetches and reads pages directly |
|
15
|
|
|
16
|
**Citation behavior:** |
|
17
|
|
|
18
|
- Provides inline citations with links when using the browsing tool |
|
19
|
- For training data responses, sources are not cited — the model synthesizes from memory |
|
20
|
|
|
21
|
- Tends to cite authoritative domains and well-structured content |
|
22
|
- Prefers content that provides clear, definitive answers over hedged language |
|
23
|
|
|
24
|
**Optimization priorities:** |
|
25
|
|
|
26
|
1. Ensure GPTBot is not blocked in robots.txt |
|
27
|
2. Focus on comprehensive, well-sourced content (training data quality) |
|
28
|
|
|
29
|
3. Strong meta descriptions and opening paragraphs (browsing tool extraction) |
|
30
|
4. FAQ-style content works well for direct question matching |
|
31
|
|
|
32
|
## Google AI Overviews (formerly SGE) |
|
33
|
|
|
34
|
**Crawler:** Standard `Googlebot` (plus `Google-Extended` for training) |
|
35
|
|
|
36
|
**How it finds content:** |
|
37
|
|
|
38
|
- Uses Google's existing search index as the primary source |
|
39
|
- AI Overviews appear above traditional search results for eligible queries |
|
40
|
|
|
41
|
- Traditional SEO signals (backlinks, domain authority, PageRank) still heavily influence which sources get cited in AI Overviews |
|
42
|
|
|
43
|
**Citation behavior:** |
|
44
|
|
|
45
|
- Shows source cards alongside the AI-generated answer |
|
46
|
- Typically cites 2-5 sources per overview |
|
47
|
|
|
48
|
- Strongly favors pages that already rank in the top 10 for the query |
|
49
|
- Uses structured data to enhance source cards (images, site name, breadcrumbs) |
|
50
|
|
|
51
|
**Optimization priorities:** |
|
52
|
|
|
53
|
1. Traditional SEO still matters heavily — domain authority, backlinks, and ranking position directly influence AI Overview citation |
|
54
|
2. Schema markup is more impactful here than other platforms because Google uses it to render rich source cards |
|
55
|
|
|
56
|
3. Content that matches Google's E-E-A-T guidelines (Experience, Expertise, Authoritativeness, Trustworthiness) gets preferential citation |
|
57
|
4. Heading-question alignment is critical — Google matches AI Overview sub-answers to page sections via headings |
|
58
|
|
|
59
|
## Perplexity AI |
|
60
|
|
|
61
|
**Crawler:** `PerplexityBot` |
|
62
|
|
|
63
|
**How it finds content:** |
|
64
|
|
|
65
|
- Real-time web crawling for every query (always fetches fresh content) |
|
66
|
- Indexes and caches frequently-cited sources |
|
67
|
|
|
68
|
- Also uses its own search index built from ongoing crawling |
|
69
|
|
|
70
|
**Citation behavior:** |
|
71
|
|
|
72
|
- Heavy citation model — almost every claim gets a numbered source reference |
|
73
|
- Cites the specific page (and sometimes section) that supports each claim |
|
74
|
|
|
75
|
- Prefers pages with clear, verifiable, specific information |
|
76
|
- Will cite multiple sources in a single answer, often 5-10+ |
|
77
|
|
|
78
|
**Optimization priorities:** |
|
79
|
|
|
80
|
1. Freshness is critical — Perplexity crawls in real-time, so up-to-date content wins |
|
81
|
2. Ensure PerplexityBot is not blocked in robots.txt |
|
82
|
|
|
83
|
3. Specific, quotable statements with data points are highly cited |
|
84
|
4. Page load speed matters — Perplexity has crawl timeouts |
|
85
|
|
|
86
|
5. Content that covers niche sub-topics well gets cited for those specific sub-queries |
|
87
|
|
|
88
|
## Bing Copilot |
|
89
|
|
|
90
|
**Crawler:** Standard `Bingbot` |
|
91
|
|
|
92
|
**How it finds content:** |
|
93
|
|
|
94
|
- Uses Bing's search index |
|
95
|
- Real-time search + AI synthesis for each query |
|
96
|
|
|
97
|
- Microsoft's AI integration means Copilot answers appear across Bing, Edge, Windows, and Microsoft 365 |
|
98
|
|
|
99
|
**Citation behavior:** |
|
100
|
|
|
101
|
- Inline numbered citations linking to source pages |
|
102
|
- Typically cites 3-6 sources per answer |
|
103
|
|
|
104
|
- Bing's index favors well-structured, authoritative content |
|
105
|
- Social signals and freshness can influence Bing ranking more than Google |
|
106
|
|
|
107
|
**Optimization priorities:** |
|
108
|
|
|
109
|
1. Submit site to Bing Webmaster Tools (separate from Google Search Console) |
|
110
|
2. Bing places slightly more weight on social signals and exact-match content |
|
111
|
|
|
112
|
3. Strong semantic HTML structure helps Bing's parser |
|
113
|
4. Clear authorship signals and organization info boost authority |
|
114
|
|
|
115
|
5. IndexNow protocol support can speed up Bing indexing of new/updated content |
|
116
|
|
|
117
|
## Cross-Platform Strategy |
|
118
|
|
|
119
|
Given that each platform has different strengths, a good cross-platform approach: |
|
120
|
|
|
121
|
1. **Don't block any AI crawlers** in robots.txt unless you have a specific reason |
|
122
|
2. **Maintain strong traditional SEO** — it directly feeds Google AI Overviews and influences Bing Copilot |
|
123
|
|
|
124
|
3. **Keep content fresh** — critical for Perplexity, helpful for all |
|
125
|
4. **Use schema markup** — highest impact on Google, but helps all platforms |
|
126
|
|
|
127
|
5. **Write quotable, self-contained statements** — this is the single most impactful practice across all AI engines |
|
128
|
6. **Submit to both Google Search Console and Bing Webmaster Tools** — covers the two major search indexes that AI engines rely on |
