Digg it and make sure you have RSS. Also since yahoo doesn't care about nofollow, maybe try commenting on a few popular blogs.
yahoo also have webmaster toolbax, yahoo indexer is usefull, submit ur sites or feeds to yahoo indexer.
Submit you site to popular social bookmarking and add your link to sig in forums, you will be index by yahoo as soon as possible.
My sites are naturally indexed into Yahoo after about three days. I don't think it's plausible to index it in 24 hours.
Just submit your site to yahoo directly.They are quite fast in indexing. Although no matter what method you use it depends upon them how long it will take to index it.
The best way to get added in Yahoo is to submit to Social Bookmarking Websites Yahoo indexed Social Bookmarking links very quickly , it might help you Another Good way is to Submit to feeds, you will find this in Yahoo webmaster tools. Hope this help you Thanks
I am submitting my site to yahoo from last 30 days. But still my site is not properly indexed in Yahoo.
