SeobilityBot

SeobilityBot is the web crawler for Seobility, a German SEO analysis and auditing tool. It is not a general-purpose crawler but a user-directed bot; it only visits a website when a Seobility user initiates an SEO analysis. The bot collects technical and on-page data to identify issues and optimization opportunities, and its presence indicates a direct interest in your site's SEO health.

What is SeobilityBot?

SeobilityBot is the SEO-focused web crawler for the German company Seobility, which provides search engine optimization tools. It functions as a technical analysis crawler that visits websites to collect data for SEO audits. The bot identifies itself in server logs with the user-agent string SeobilityBot (SEO Tool; https://www.seobility.net/sites/bot.html). Unlike search engine crawlers, SeobilityBot collects data specifically to power Seobility's analysis tools and reports.

Why is SeobilityBot crawling my site?

SeobilityBot is crawling your website because a user of the Seobility platform has requested an SEO analysis of your site. The bot is gathering technical data and analyzing content quality, mobile responsiveness, and other SEO factors. The frequency of visits is not on a regular schedule but is triggered by these specific analysis requests. The crawl may have been initiated by your own team or by a third party conducting competitive SEO research.

What is the purpose of SeobilityBot?

The purpose of SeobilityBot is to power Seobility's SEO analysis and monitoring tools by collecting real-time data about websites. The goal is to provide website owners and SEO professionals with comprehensive insights into their site's optimization status. The data it collects helps identify technical issues, such as broken links or slow-loading pages, and provides recommendations for improvement. For website owners, this service can provide valuable insights that help improve search visibility and user experience.

How do I block SeobilityBot?

To prevent SeobilityBot from analyzing your site, you can add a disallow rule to your robots.txt file. This will block users of the Seobility tool from running audits on your website.

To block this bot, add the following lines to your robots.txt file:

User-agent: SeobilityBot
Disallow: /

How to verify the authenticity of the user-agent operated by Seobility?

Reverse IP lookup technique

To verify user-agent authenticity, you can use host linux command two times with the IP address of the requester.

```
> host IPAddressOfRequest
```
This command returns the reverse lookup hostname (e.g., 4.4.8.8.in-addr.arpa.).

> host ReverseDNSFromTheOutputOfFirstRequest

If the output matches the original IP address and the domain is associated with a trusted operator (e.g., Seobility), the user-agent can be considered legitimate.

IP list lookup technique

Some operators provide a public list of IP addresses used by their crawlers. This list can be cross-referenced to verify a user-agent's authenticity. However, both operators and website owners may find it challenging to maintain an up-to-date list, so use this method with caution and in conjunction with other verification techniques.
