When i give search in Yahoo with my "Domain" name. It displays search results. It shows to me that my home page in not shown "cached" . And other url's of other site shows "cached" Whether can it affect my search engine ranking??? Or whether my site is not properly listed with yahoo??? In google it shows "cached". Help?? I am confused???
If a page is not cached, then there is no information about it. It means that that the page's information has been indexed and placed into the database. So basically, you need to get that page to have a "cache" or you ain't getting no traffic.---
ROAR not really, that only happens if, when searching only the URL appears with no texto whatsoever. If you use the tag noindex it will still rank your websites, you just won't see the cached version.
