Frequently Asked Questions
Should I Block Seznam?
No, unless you want to remove your pages from that search engine. Seznam supplies its index, so blocking it can eliminate your visibility and organic traffic there. Nearly every website should allow this category. For context, 6% of the top websites we track currently have robots.txt rules for Seznam.
Does Seznam Follow Robots.txt Rules?
Yes. Seznam is expected to follow robots.txt rules, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Seznam respects it.
Does Seznam Access Private Content?
No special access. Seznam can reach only content available to anonymous visitors and does not sign in. Make sure sensitive content is not public by mistake.
How Can I Tell if Seznam Is Visiting My Website?
Agent Analytics tracks Seznam visits in real time. You can also check your server logs for requests whose user-agent string contains "Seznam". Look for recurring passes that revisit changed pages and discover new ones. Because Seznam does not publish a verification method, any client can claim its identity and a log match is only a clue.
Why Is Seznam Visiting My Website?
Seznam is adding new or changed pages to its search index. It may have discovered your site through links, a sitemap, or direct submission.
