Gabanzabot is the web crawler we have developed to facilitate comprehensive data gathering and indexing across the web. As a robust web crawler, it is designed to navigate the vast expanses of the internet with the goal that websites are indexed accurately and in a timely manner.
To meet the demand of crawling the ever changing internet, it undergoes rapid development as we continue to refine its capabilities. This evolution is driven by both the accumulation of operational experience and advancements in web crawling technology. Our team consistently works on enhancing Gabanzabot's functionality to better meet the dynamic needs of digital content management. These enhancements are focused on improving the crawler's efficiency, coverage, and the ability to intelligently navigate and index complex web architectures, ensuring that it remains a valuable tool for data retrieval and analysis.
Web crawlers, also known as spiders or bots, are automated software programs designed to systematically browse the World Wide Web and gather information from websites. Their primary function is to index the content of websites to facilitate faster and more accurate information retrieval. Crawlers are integral to search engines, where they play a crucial role in collecting data that is subsequently processed and indexed. By following links from one webpage to another, crawlers can collect a vast array of data, including text, images, and video content, allowing search engines to build extensive databases that power the search results delivered to users.
The operation of web crawlers is guided by specific algorithms that determine which pages to visit, how often, and how deeply the crawler should navigate through a website. This process not only helps in updating existing entries in a search engine's index but also in discovering new pages and sites. To manage their interaction with websites, crawlers often respect rules set by the robots.txt file on each site, which specifies the parts of the site that are off-limits to crawlers. This ensures that crawlers operate efficiently without overwhelming web servers or accessing sensitive areas of websites, thereby maintaining the web ecosystem's integrity and functionality.
The crawler operates within a dedicated IP range, specifically 207.231.111.0/24 for IPv4, with plans to expand its operations to IPv6 shortly, demonstrating our commitment to embracing cutting-edge technology and infrastructure.
Robots.txt is a text file webmasters create to instruct web robots (typically search engine crawlers) how to crawl pages on their website. The file is placed at the root of the website (e.g., https://example.com/robots.txt) and tells robots which pages or sections of the site should not be processed or scanned. This can help manage crawl traffic and ensure that private or unimportant sections of a site are not indexed by search engines.
robots.txt.
User-agent to specify which crawler the
rule applies to.
Disallow to specify the path you want to
block.
Allow to specifically allow
access to certain paths.
To control Gabanzabot from accessing to your website, you can implement the techniques outlined below. However, please note that the most effective way to safeguard private areas of your site is to password-protect them. While we respect your instructions and will take them into account, password protection offers a direct and reliable method to control access to sensitive content.
robots.txt FileThe robots.txt file, located at the root of your website, instructs web crawlers on how to
interact with your site.
Add the following lines to prevent Gabanzabot from crawling any part of your site:
User-agent: Gabanzabot
Disallow: /
Specify the paths you want to restrict:
User-agent: Gabanzabot
Disallow: /private-section/
Disallow: /confidential-page.html
Implement meta tags to control crawling on a per-page basis.
Insert the following meta tag within the <head> section of each HTML page you
want to exclude:
<meta name="robots" content="noindex, nofollow">
Note: This instructs all crawlers not to index the page or follow any links on it.
Set HTTP headers to control access to non-HTML content or when you cannot modify the HTML directly.
Configure your server to include the following header in the HTTP response for specific files or directories:
X-Robots-Tag: noindex, nofollow
Block Gabanzabot at the server level using configuration files.
.htaccess):
Add these rules to your .htaccess file:
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} Gabanzabot [NC]
RewriteRule .* - [F,L]
Include the following in your server configuration:
if ($http_user_agent ~* "Gabanzabot") {
return 403;
}
Use authentication to restrict access.
Protect directories or pages with a password, which crawlers cannot bypass:
AuthType Basic
AuthName "Restricted Area"
AuthUserFile /path/to/.htpasswd
Require valid-user
