Is it possible to send other people's URLs?

Yes, technically, the service can submit any publicly accessible URL for indexing—not just your website's pages. For example, many SEO specialists use such services to speed up the indexing of pages with backlinks, guest posts, brand mentions, or PR materials published on third-party resources.

Submitting someone else's URL in itself is usually not a violation: search engines regularly find and crawl public pages automatically. The service simply helps quickly draw the search engine's attention to an existing URL.

The most common use cases are:

• indexing pages with placed backlinks;

• accelerated discovery of new guest post materials;

• indexing donor pages after purchasing links;

• accelerate the appearance of brand mentions in search;

• Re-indexing updated public pages.

It is important to understand several points.

Firstly, the service does not grant any rights to the content or domain itself. The user is solely responsible for which URLs they submit and for what purpose they use the service.

Secondly, indexing is not guaranteed. Even if the URL has been submitted, the search engine may:

• ignore page;

• do not add it to the index;

• delete it later;

• consider the page to be of little use or duplicate.

This is especially true for:

• spammy backlinks;

• doorways;

• automatically generated pages;

• closed or restricted content;

• pages with noindex;

• technical and temporary URLs.

It's also not recommended to mass-submit other people's URLs without understanding their quality. If a page contains spam, malicious content, or violates search engine guidelines, it may be useless or even harmful to your overall SEO strategy.

Simply put: submitting other people's public URLs is technically possible, and it's widely used in SEO, especially for backlink indexing. However, the service is merely a tool for speeding up page discovery, and the user remains responsible for the nature and quality of the URLs they add.
