What types of links can I send?

2index.ninja allows you to submit virtually any URL containing backlinks for indexing , regardless of their type or format. The main goal here is to help search engines like Google and Yandex quickly discover the donor page and register the link located on it.

Crowdlinks are most often used in link building—these are mentions and links posted on forums, in discussions, and in comments. Such pages often have low internal visibility and may not be indexed immediately, so submitting them for indexing helps speed up their inclusion in search results.

A separate category is forum links and profiles. These can include user profiles, signatures, discussion threads, or account pages. They are often created on large platforms with highly dynamic content, where new pages may remain unindexed for a long time due to prioritization of more popular sections.

You can also submit guest posts and articles published on external sites. Although such pages are usually of higher quality, their indexing may still be delayed, especially if the donor site has weak interlinking or a limited crawl budget.

Links from comments are another common type. They are often posted on blogs and news sites and can be technically difficult for search engines to access, especially if they are located deep within the site structure or loaded dynamically.

Catalogs and directories are also typical donor sites. Such sites often contain a large number of pages with a similar structure, and new additions may be indexed with a delay.

PBNs and web 2.0 platforms deserve a special mention. These are infrastructure-based donor sites often used for SEO experiments and link building. Their pages often have unstable indexing, so accelerating discovery can be critical to achieving results.

You can also submit links from press releases , media publications, and other article-based sites. Even if such resources are highly authoritative, new pages still don't always get indexed immediately.

Finally, you can upload any URLs from link building campaigns to the service , regardless of their source, as long as they are crawlable and not limited by technical settings.

It's important to keep in mind a key principle: the type of link itself does not guarantee its indexing. Search engines evaluate not only the presence of a URL but also the quality of the source page, its structure, content, and internal and external signals. Therefore, even with the same type of link, some pages may be indexed quickly, while others may be delayed or not indexed at all.

This is why link indexing works best when combined with high-quality donors and proper technical preparation of pages.
