Spider Trap

Definition of spider trap

spider trap refers to a situation in which a indexing robotas Googlebotis trapped in an infinite loop when it explores the pages of a website.

These loops can be caused by errors in the internal networkingor incorrectly configured dynamic links or redirection problems.

The consequences of a spider trap are detrimental to your SEO, as they lead to inefficient crawling of your site by search engines and can also lead to poor indexing or even downgrading.

How are spider traps formed?

There are several causes that can lead to training of a spider trap. Here are the main ones:

  • Misconfigured internal links : when your site's internal links direct crawlers to irrelevant or non-existent URLs, they can become trapped in an endless loop of exploration.
  • Redirection problems : errors in the management of permanent (301) or temporary (302) redirections can also create infinite loops for the indexing robots.
  • URL dynamic : incorrect or abusive parameterisation of dynamic URLs is another frequent cause of spider traps. By endlessly generating URLs with different parameters, you run the risk of trapping crawlers and wasting their precious time.
  • Calendars online : if your site offers an online calendar covering several years, consider blocking access to past and future dates that are too far apart, to prevent robots from getting lost.

How do you detect a spider trap?

Detecting the presence of a spider trap can be tricky, as the phenomenon is not always easily identifiable. But here are a few clues that can help:

  1. Abnormal traffic : unusually high traffic or significant fluctuations in the number of pages viewed can be a sign of a crawling problem.
  2. Recurring 404 errors : if your SEO tracking tool displays numerous 404 errors despite your efforts to resolve them, this may indicate the presence of a spider trap.
  3. Increased crawl time : if you notice a significant increase in the time it takes for indexing robots to crawl your site, this may be due to a robot trap.

Tools for detecting spider trap

To identify and correct spider traps, it is essential to use high-performance SEO tools. Here are some of the most popular:

    • Google Search Console : This free tool from Google allows you to monitor the health of your site and spot any crawling problems.
    • Screaming Frog : This comprehensive, pay-as-you-go software is a benchmark in website analysis. In particular, it detects meshing errors and redirection problems.
    • Xenu's Link Sleuth : A free alternative to Screaming Frog, Xenu's Link Sleuth also helps you track down broken links and spot errors in your site architecture.

How can I avoid spider traps?

Now that you know the main causes and methods of detecting spider traps, here are a few tips on how to avoid them:

  • Check your internal links regularly: make sure that all your internal links are functional and lead to relevant pages.
  • Set up your dynamic URLs correctly: make it easy for crawlers to identify the different versions of your pages and avoid generating endless URLs.
  • Optimise the management of your redirects : use the appropriate HTTP codes for permanent and temporary redirections, and regularly check that they are working properly.
  • Use the robots.txt file: This file is used to give instructions to the indexing robots on which areas of your site to explore or ignore. Use it to block access to irrelevant sections, such as calendar archives, for example.

To sum up, preventing and resolving spider traps is an important part of any SEO strategy.

By ensuring the quality of your internal meshing and the relevance of your links, you will optimise the exploration of your website by search engines, improve its indexing and promote better positioning in search results.
