Google Cache is important part of SEO, but guys last night i talked with my friend and He was saying that he can cache any site or blog just in 2 second but not shared his technique, Can any tell me solution, is it possible in 2 sec. any site cache in google without any work, if yes then please share it.
in 2 seconds! lol the guy is having you on mate! If he thinks he can really do it, tell him you want to see some real time examples of him doing it, your supply the pages which are new and he can get them cached for you in 2 seconds each! I bet he says no, because its bull! lol
I have tested him and i send him 5 fresh blog and after few minute when i saw i found my all blog indexed in google, its not jock, i was shocked when i saw but its true.
Are you talking about indexed pages or cached pages? A page that's indexed don't always mean its cached! Now if you're talking about getting a page indexed in a couple of minutes (with is a lot longer then 2 seconds btw lol), then yes there are a few techniques that can achieve this. If you send me the exact urls he did on for you I could probable tell you what he did after taking a quick look at em
I bet you're just confusing cache to index (no idea how), and getting indexed in matter of minutes is no super secret method anyways.
A sudden outburst on twitter with retweets, favorites, replies, also +1's Google+ and likes on Facebook would help your page indexed by Google asap. For all this to happen the content quality is what matters.
