Today, Matt Cutts released a video, advising not to duplicate Meta descriptions on your website. Matt said that you should avoid duplicating the same Meta descriptions across your website pages, instead, you should create 100% unique Meta descriptions.

Matt suggested having No Meta descriptions OR having 100% unique meta descriptions rather than having duplicate descriptions. Meta descriptions have been an important part of the Google Search algorithm in past, we have seen that in past Google eliminated the importance of the “Keyword” Meta tag as well.

Matt said that even his own blog does not have any Meta descriptions, he leaves this work to Google algorithm to create appropriate snippets. If your website does not have Meta descriptions, Google’s search technology created and display itself based on your page contents.

So next time, if you do not have time to create unique Meta descriptions, it better is to leave them and let Google do its work while you create quality content for your website or read meta tags optimization here
