How can certain spiders/crawlers be blocked across the board?
Posted: Mon Apr 21, 2025 4:13 am
As can be clearly seen in the structure, all user agents that should be blocked are first listed in robots.txt. The "Disallow: /" then clearly indicates that the spiders are not allowed access to the website and its subpages and subfolders. Therefore, the domain is completely excluded for the specified user agents and therefore cannot be crawled.
What alternatives are there to robots.txt?
There are also systems that do not allow a robots.txt file to be stored on the server. However, oman phone number data there is a workaround for this. The most important function, crawling, can also be integrated via the HTML header. Addressing specific bots can also be done this way, as the following examples show, so that even though a robots.txt file could not be created, the instructions can still be taken into account.
Parameter handling using robots.txt?
As briefly outlined in the table above, websites, or subpages, can be removed from the index or blocked from the index using parameters. Anyone who has a search on the website should take a close look at the URL generated when the search results page of the respective search engine, such as Google, is accessed. In most cases, the domain will then be appended with the following: "?siteSearch=..." This parameter can then be excluded in the robots.txt file so that all pages generated by the "siteSearch" are excluded from crawling/indexing. Of course, you can also make life easier.
If you don't have access to the server or lack the technical knowledge to edit robots.txt, you can also consult the Google Search Console's parameter handling and make the desired changes there. SEOs with technical expertise are often required to correctly implement the instructions in robots.txt.
