are you talking about google webmaster tool the index part or the actual when you type in search box the site:domain...?
Anything involving a search box is google search. What do you mean by "the index part"? The "Submit to index" option that comes after "Fetch as googlebot" in wmt?
if i type <EMD keyword> in search query box
Uh-oh, Sandra, I think you may have snipped some essential information here.
"EMD keyword" = name of domain
"EMD keyword" = "site:" operator?
EMD as such isn't a very good test in google, unless you're something huge like amazon. In general it works much better in bing.
not indexed by google for the past few days..its shows 404 error.
This can only be in wmt, because google search doesn't say anything about 404. A link from search might lead to a 404, but the search results themselves don't give this number.
Even i have given fetches all pages to index.
Can you say this again in different words? I think there's a bit of a language problem, so we need to be very unambiguous. Question
. Do you have access to your site's raw logs? If yes, has the googlebot tried to crawl? If yes, what response did it receive?
