Should duplicates be removed from the list?

Yes, removing duplicates from your URL list is not just a recommendation, but a good practical habit when working with indexing and SEO in general.

Duplicate URLs create several problems at once:

First, they consume the service's limits. If you have, for example, 1,000 rows, of which 200 are duplicates, you're effectively wasting some of your available space without any real benefit.

Secondly, duplicates distort analytics. When the same URL is submitted multiple times, it's harder to understand the actual result: whether the page was indexed or simply re-processed.

Third , this can lead to unnecessary load on the indexing process. Search engines already filter duplicates, but unnecessary queries don't improve efficiency and sometimes slow down the overall processing.

Therefore, before downloading a large list of URLs, it is generally recommended to:

  • remove exact duplicates (identical lines);

  • check URL with/without slash at the end (/, /page and /page/);

  • bring addresses to a uniform format (http vs https);

  • remove parameters if they are not needed (utm, session, etc.);

  • normalize case if it is important for the site structure.

The end result is a unique, clean list of pages that is easier to manage and analyze.

Simply put, duplicates don't directly "break" indexing, but they make the process less efficient, waste resources, and interfere with obtaining an accurate picture of the results.
