Welcome to the Q&A Forum

I read something in Google support a while ago that stated that Google auto suggest is based on amount of people searching, which makes it show up. so best option is to employ someone or a team of people to do the same search all day long....:)

i have few account in my webmaster tools that are not showing any link data even the has lots of links.

i checked the setup and its everything is good.

is some one tell me why there is no data coming through?

Thanks

Depends on your needs - I use statcounter.com for simple sites . for more full on sites- Look as Kissmetrics (has some very key metrics for customer tracking)
