You can use website data collection services that gather information about websites. You can use them effectively to distribute the URL of your page and obtain backlinks. Examples of such services include Bulklink.org, Indexkings.com, Pingfarm.com, and Linkcentaur.com. Additionally, you can use the Mass Fast Pinger extension for Google Chrome.
Social MediaIf users from other websites frequently click on the link to your page, search engine crawlers will take notice. Social media can be used to generate both paid and free traffic. A skilled SMM specialist can ensure the necessary visits to pages that have not been indexed.
YouTubeIf you have your own YouTube channel, you can upload new videos with a link to the page that needs indexing. This works very effectively for channels with a large audience.
If you don't have your own account, you can arrange with other channel owners. In this case, you may need to pay or offer a reciprocal service.
