I just want to know when we are creating map backlinks on Web 2.0 and other sites, which link do we need to publish like the Google Maps link or that HTML code?
And what about creating PBN links on 2-tier for indexing 1-tier backlinks which are map backlinks?

1. You should use the Google Map Link

2. creating Tier 2 is good ide but make sure about the content quality and site relevancy for more effect.

Publish Google Maps link for map backlinks on Web 2.0.
