SogouSpider follows robots.txt, so these rules stop it crawling the paths you choose. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.
User-agent: Sogou Disallow: /
User-agent: Sogou Disallow: /private/ Disallow: /search
User-agent: Sogou Allow: /blog/ Disallow: /
User-agent: Sogou Allow: / User-agent: * Disallow: /
User-agent: Sogou group, SogouSpider ignores your User-agent: * rules, so repeat any that should still apply.Sogou from SogouSpider's user agent; check Sogou's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
SogouSpider brings search traffic, so keep the real one allowed. Fake SogouSpider requests are a common cover for scrapers, so verify it by network rather than by name.
Transfon Security for publishersSearch crawlers fetch landing pages to check them. Keep SogouSpider allowed, but out of campaign and conversion data.
Transfon Security for advertisersSogouSpider indexes products for search results. Allow it, and block impersonators that use its name to scrape prices.
Transfon Security for e-commerceAllow SogouSpider on marketing and docs pages, and keep it off signed-in app pages it cannot use.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows SogouSpider by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

Yes. SogouSpider follows robots.txt, so a Disallow rule for the Sogou user agent stops it from crawling the paths you list.
Add "User-agent: Sogou" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "Sogou" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so SogouSpider may not follow it, and anyone can send SogouSpider's user agent, so a fake SogouSpider ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
