how can it be possible? Just few hours ago i launched by site and now its seen in google. My site is top-best-themes.com I never submitted to google and typically it takes about a week for sites get indexed.
You website is made on WP platform and every time you add anything to your site via WP, an automatic ping is sent to all major search engines. That should explain why.
When you setup Wordpress you were asked if you wanted to advise the search engines of the site, and you obviously clicked yes. Or don't you remember?
hi, This is new for me.. but possible to happen. I might think that google crawling hit your site and get index. Your Lucky J.
nothing shocking, you can get your site indexed in 10 minutes depending on where you submit your site
