What is YisouSpider?

YisouSpider is Yisou's search engine crawler. YisouSpider is a search engine crawler operated by Yisou that indexes web content for their search engine results. The crawler follows standard crawling practices and respects robots.txt directives.

YisouSpider powers a search engine, and search indexes increasingly feed AI answers and overviews alongside classic results. The pages it can crawl are the pages eligible to rank and to be pulled into AI-generated summaries, so allowing it protects both your SEO and your AI search visibility.

Like any automated client, YisouSpider consumes crawl budget and appears in your server and CDN logs. Reviewing those logs alongside your robots.txt rules helps you keep automated traffic deliberate and easy to reason about.

User-agent: YisouSpider
Disallow: /
