How long does it take for SE's to notice backlinks... i have distributed a large amount of back links and when i do a backlink search to my site only a few show up? Is there a way to speed up this process like pinging or something?
One thing is noticing and a completely different thing is showing. Google notices (and considers) backlinks very quickly, but the list that's being displayed when you search for links or look at GWT is updated only once every couple of months.
Check in yahoo for backlinks, yahoo updates all new backlinks very fast. Google doesnot show all backlinks or they just intentionally show poor quality backlinks at first and hide some backlinks, although they count all backlinks internally when ranking.
Here is an excellent resource on the topic http://www.seomoz.org/blog/google-link-command-busting-the-myths
For a new build websites/blogs or newly build links to it, it takes 2 to 3 weeks before you can see your backlinks in you website/blog according to my experience.
well i have my own technic to build backlink fast,wait for the time,There is comparative between yahoo and google
I think it may take between days to weeks, depending on the frequency in which google caches the website where your backlink comes from. It may help to ping the website where the backlink originates.
