What is PageSourceSearchBot?
PageSourceSearch indexes source bytes rather than rendered page text. Its operator says the bot fetches robots.txt, up to five public pages per site and their first-party scripts, then makes exact text and regular-expression search possible across that material. It follows robots.txt, does not log in or submit forms, and provides an opt-out token for site owners.
User Agent String
Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; PageSourceSearchBot/1.0; +https://pagesourcesearch.com/bot) Chrome/128.0.0.0 Safari/537.36
How to Control PageSourceSearchBot
Block Completely
To prevent PageSourceSearchBot from accessing your entire website, add this to your robots.txt file:
# Block PageSourceSearchBot
User-agent: PageSourceSearchBot
Disallow: /
Block Specific Directories
To restrict access to certain parts of your site while allowing others:
User-agent: PageSourceSearchBot
Disallow: /admin/
Disallow: /private/
Disallow: /wp-admin/
Allow: /public/
Set Crawl Delay
To slow down the crawl rate (note: not all bots respect this directive):
User-agent: PageSourceSearchBot
Crawl-delay: 10
How to Verify PageSourceSearchBot
Verification Method:
The operator documents the user-agent and robots token but does not publish an IP or DNS verification method on its crawler page. A string match alone cannot authenticate a request.

Detection Patterns
Multiple ways to detect PageSourceSearchBot in your application:
Basic Pattern
/PageSourceSearchBot/i
Strict Pattern
/^Mozilla\/5\.0 AppleWebKit\/537\.36 \(KHTML, like Gecko; compatible; PageSourceSearchBot\/1\.0; \+https\:\/\/pagesourcesearch\.com\/bot\) Chrome\/128\.0\.0\.0 Safari\/537\.36$/
Flexible Pattern
/PageSourceSearchBot[\s\/]?[\d\.]*?/i
Vendor Match
/.*PageSourceSearch.*PageSourceSearchBot/i
Implementation Examples
// PHP Detection for PageSourceSearchBot
function detect_pagesourcesearchbot() {
$user_agent = $_SERVER['HTTP_USER_AGENT'] ?? '';
$pattern = '/PageSourceSearchBot/i';
if (preg_match($pattern, $user_agent)) {
// Log the detection
error_log('PageSourceSearchBot detected from IP: ' . $_SERVER['REMOTE_ADDR']);
// Set cache headers
header('Cache-Control: public, max-age=3600');
header('X-Robots-Tag: noarchive');
// Optional: Serve cached version
if (file_exists('cache/' . md5($_SERVER['REQUEST_URI']) . '.html')) {
readfile('cache/' . md5($_SERVER['REQUEST_URI']) . '.html');
exit;
}
return true;
}
return false;
