Google add url

Hello to all!
I found a website that adds url to Google (not from my website but for pages from third-party websites I input) and this in theory speeds up the backlink indexing.
Of course, someone may just wait until Google eventually indexes the backlinks but still I would like to ask:
1. Is this service (Google add url) feasible or just a pipedream?
2. If this service is valid, what other (free) tools can perform this actions?

Thank you in advance,
Al

 

I don't think now a days "add URL" in Google available.
if you would like to submit your website URL, then go with "Google search Console." I mean to say, submit your url via Google search console.

 

Being an experienced SEO professional, i always discourage manual indexing. Better is to focus on consistency.

 

Thank you for the reply.
I just need to inform Google about other sites' updated pages.
LinkBox is doing it in a matter of days automatically and I think it's working good.
But it's not free and I am looking for an alternative free version.

 

Go to Google Search Console. In the navigation pane, choose Add property or Search property. Click Add property. In the Domain (not URL prefix) option, enter the domain you want to verify.
