Frequently Asked Questions

Should I Block Leikibot?

If you run ads, confirm Leikibot's purpose before blocking it. Some intelligence gatherers measure ad placements or evaluate pages for brand safety, and blocking those agents can interfere with advertising systems.

Does Leikibot Follow Robots.txt Rules?

How Can I Tell if Leikibot Is Visiting My Website?

Agent Analytics tracks Leikibot visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "Leikibot". Look for repeated requests to the same small group of commercial or ad-supported pages.
