Why Is Viber Visiting My Website?
Someone shared a link to your page. Viber fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
Should I Block Viber?
Usually not. Blocking Viber may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. For context, 7% of the top websites we track currently have robots.txt rules for Viber.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Viber?
Viber usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.
Does Viber Follow Robots.txt Rules?
No. Viber is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is Viber Used for AI Model Training?
Not ordinarily. Viber is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Viber Affect AI Search or Citations?
Not directly. Viber's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Viber Access Private Content?
No. Viber has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
How Can I Verify a Request From Viber?
Agent Analytics tracks Viber visits in real time. You can also check your server logs for requests whose user-agent string contains "Viber". Look for a page and its preview assets being requested without follow-up navigation. Because Viber does not publish a verification method, any client can claim its identity and a log match is only a clue.
