Hi,
I came across a service that provides free 400-500 backlinks to any website, and also allows you to ping it to 10-odd services for faster indexing.
This service is similar to the excellent IMT Website Submitter created by Nemanja, but it may have some non-overlapping submissions.
Check out: freebacklinktool.com
They also have a Youtube video of instructions at: youtube.com/watch?v=C8RBOcZU4wo
Do note, this is not my tool, I am just sharing something I came across.
Best Regards,
Rushin
