Green tested 1,000 prompts up to 10 times each and captured 9,946 completed search runs. Most prompts stayed on one retrieval source. Labrador accounted for 88.1% of primary search sources in his dataset, followed by Bright at 9.9%, Oxylabs at 1.7%, and SERP at 0.3%.<\/p>\n<ul class=\"wp-block-list\">\n<li>But 11.6% of prompts changed primary search source across repeated runs.<\/li>\n<li>URL overlap dropped from 0.273 to 0.149 when the search source changed. Domain overlap fell from 0.265 to 0.155. Green calculated that as roughly 45% lower URL overlap and 42% lower domain overlap.<\/li>\n<\/ul>\n<p><strong>The labels behind results<\/strong>. Mohanadasan inspected two days of raw ChatGPT network traffic from one logged-in Pro account and logged about 1,240 source records across a few dozen searches.<\/p>\n<ul class=\"wp-block-list\">\n<li>He found a <code>result_source<\/code> field attached to web results, with four observed values: SERP, Labrador, Bright, and Oxylabs.<\/li>\n<li>He described Labrador as including established publishers and reference sites, Bright as tied to Bright Data, Oxylabs as tied to Oxylabs, and SERP as an open-web baseline that <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>eared mostly in <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>-style results.<\/li>\n<li>Green\u2019s repeated-prompt test found Labrador dominated his dataset. Mohanadasan saw Bright play a larger role in his sample, especially for commercial, shopping, finance, weather, and local queries.<\/li>\n<\/ul>\n<p><strong>Some prompts skipped search<\/strong>. Mohanadasan also found that ChatGPT classified some queries before searching, using a <code>turn_use_case<\/code> field. Some prompts were filed as text and skipped web search entirely, even when they sounded current. In those cases, no page could be fetched, cited, or used as evidence.<\/p>\n<ul class=\"wp-block-list\">\n<li>More complex \u201cthinking\u201d queries behaved differently. Mohanadasan found that ChatGPT could fan out into many searches, including <code>site:<\/code> probes, pricing checks, and searches for unnamed competitors.<\/li>\n<li>That behavior changes which pages can enter the answer process because ChatGPT may search rewritten queries, direct site probes, or follow-up checks instead of the exact phrase a user typed.<\/li>\n<\/ul>\n<p><strong>Fetched was not cited<\/strong>. Mohanadasan separated three outcomes: fetched, cited and mentioned.<\/p>\n<ul class=\"wp-block-list\">\n<li>A page can be fetched into ChatGPT\u2019s context without being shown to users. It can be cited as the source behind a specific sentence. Or a brand can be mentioned without being the source of the claim.<\/li>\n<li>In his small commercial-query sample, Reddit and <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">YouTube<\/a> were both fetched often, but Reddit was cited and YouTube was not. He attributed the gap to text availability: Reddit threads expose text, while YouTube search results often provide metadata rather than full video transcripts.<\/li>\n<li>Vendor pages were cited for their own facts, such as prices and specs. Third-party pages were more likely to support broader recommendation claims.<\/li>\n<\/ul>\n<p><strong>Why we care<\/strong>. There\u2019s no single ChatGPT visibility result to measure. Your page may never be considered if ChatGPT skips search, uses another retrieval source, or finds a clearer third-party page to support the claim.<\/p>\n<p><strong>Readable pages were easier to use<\/strong>. Both analyses showed that ChatGPT\u2019s source selection depended partly on what it could retrieve and read.<\/p>\n<ul class=\"wp-block-list\">\n<li>Mohanadasan found cases where ChatGPT appeared to prefer official pricing pages, then fell back to third-party sources when prices were hidden behind JavaScript or otherwise hard to parse.<\/li>\n<li>Green\u2019s results showed that source routing changed which URLs and domains entered the answer set.<\/li>\n<li>Plain HTML, crawlable facts, clear pricing and specs, strong third-party coverage, and text-heavy pages became more important when source selection depended on retrieval and readability.<\/li>\n<\/ul>\n<div class=\"ttd-topics-display\">\n<div class=\"ttd-topics-content\">\n<h5><span class=\"ez-toc-section\" id=\"Topics_on_this_page\"><\/span>Topics on this page<span class=\"ez-toc-section-end\"><\/span><\/h5>\n<div class=\"ttd-topics-links\">ChatGPTBright DataLabrador RetrieverOxylabs, UABSearch engine optimizationArtificial intelligenceData analysisInformation retrievalJavaScriptRedditSearch engine indexingWeb scrapingYouTube<\/div>\n<\/div>\n<div class=\"ttd-topics-show-extra-button\">+8 more<\/div>\n<\/div>\n<\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
