Question about google search engine

if the meta tag description in a site is diffrent then one a person wants to have in google search engine, can you change that with out changing the meta tag description in a site???

So you want to change it without changing it?
Why do you want to change it in google and not on your site?

If you want to change the description in google SERPs, change your meta description.

As Tybi said changing your Meta Description is the first step. If the meta description is relevant to the site it is likely to be used by Google however Google does still sometimes make its own. If the Desc tag appears to be spammed with a bunch of keywords it will likely not be used.

Google usually grabs a snipet of your content that mentions the searched for phrase... don't they?

Yeah from my experience google will only use the meta description if it contains at least some of the keywords that the searcher was searching for.

A well written and targeted meta description is Google's first default.

Can be 2 possibilites.. Either there is not meta description, in case thats the case, the cralwer by default catches up a few lines from the content..

Second one, in case the site is listed in dmoz then probably it can pick up description from dmoz and not what u desire..

Solution to the first one is like everyone said above, gotta change the meta description..

Solution to the second one u can use the meta noodp tag in the page.. and after a few dasy u will see the original description back..

Probably that shud help you..

There is another case:

There is a meta description, but it doesn't contain the searched phrase.
So google again picks the snippet of your content which includes the keyword.

Google displays the snippet as when u search for a particular term in google then it will first finds your title, meta tags and if the that searched keyword is there it will display that but if it is not there but it is in content of your site it will display that part of the content with that keyword in the snippet.

And you cant change snippet from google.
