I know google doesnt follow the nofollow tag, but lets say a website doesnt have the nofollow for its trackbacks, will posting a trackback count as a backlink when nofollow tag is absent.
Ofcourse, it will be considered as a backlink, because google won't be able to know whether it is a trackback or not. For google it is a link.
another quick question how long does it take for google to show serp results for a website that you have a backlink from.
The time taken for Google to show the backlink depends on how fast Google is crawling the site. There are two ways to check for the nofollow attribute * View the source of the page and check for somthing like rel="nofollow" * Install the firefox extension Search Status and enable the option Highlight Nofollow Links
