You can wait for search engines to index your content naturally, but manually submitting it can accelerate the process, especally for new websites or recently publishd material.
In most cases, I'd just let search engines find them naturally. Good backlinks usually get indexed on their own. Manual indexing can help sometimes, but it's not something I worry about for every link.
i do not index each page myself. i mostly just wait bcuzz google is pretty adept at crawling nd indexing new pages as long as the webssite itself is in good order. i will request the indexing only when it really matters.
It is not necessary many good sites are present where you can post your article the google crawler will pick you article automatically and it will be indexed even with in 10-30 minutes of the posting time i have experienced in this regard too.
