My site has been down since 10 days and i hav redirected it to some other URL. And now i found out dat, even it's home page is dropped from d index. What should i do to bring it again in google's index.
If google spiders your url and it does not find a page it will not list it. If you get the page back up it should re list it again.
That's pretty much it. If the page is there, and if it has one single inbound link it will get eventually listed.
Pls make sure your web site is up and then it cache your page when it will crawl your site. (may be from any backlink to your site).
Yes, I do not submit to SE these days. Just link in from existing sites and it'll be re-index in no time.
Just improve your link popularity and when the other site has been crawled with your link on it your site will be re-index...Goodluck...
Maybe start a link pop campaign since google will spyder through other's website, the trail will go towards you eventually.
