User-Agent Parser

The User‑Agent is a text string that a browser or search crawler sends to the server with every request. It contains information about the client type, operating system, browser version, and other details. For an SEO specialist, analyzing the User‑Agent is a key way to understand who and how interacts with the site. It helps distinguish real users and legitimate crawlers (for example Googlebot) from malicious bots or spam crawlers that may harm the resource or distort analytics.

Our User‑Agent parser instantly decodes this string and provides a detailed report. You will see the device type, operating system, and browser version, which helps with debugging and verifying correct indexation. For example, you can confirm that Google is crawling your site with a mobile crawler, which is critical for mobile SEO. Timely analysis of the User‑Agent helps block unwanted traffic and ensures that search engines see your site as intended.
