Hii.........guys any idea related to site links ...........i had checked so many websites in which Site links ......appears in Google.co.in but Not in Google.com Why its happening .........
That's simply because Google thinks your website is more authoritative in India locally than globally. Could be related to the nature of incoming links or current traffic on site. Well done and good luck with your SEO.
As maltadude said, your website is being seen as authority in Google.co.in over Google.com. It could because of - Your website inbound links are most from India based websites - Your domain may be .co.in extension - Your website may be hosted in India based hosting company - Your content are more relative to India over international
Geographic location definitely has effects on this kind of scenario where your site has good authority on certain location. As always, Google ran different factors on their algorithm, especially on geographic location.
