Why Use Meta Description or Keyword Tag? Google Doesn't

[wiseapple]

I have gotten rid of the meta description and keyword tags from some of our articles... I was surfing a few Google sites and noticed that they do not use any meta tags. Take for example Matt Cutt's (Google Employee/Insider) blog. Take a look at his source. No keywords or descriptions. He ranks for plenty of search terms. Also, take a look at any other Google page (ex: Adwords) - no keywords or description.

Do they no longer play into ranking? Since I have dropped these, can anyone predict what the outcome will be?

Appreciate all thoughts.

I wouldn't omit the description meta tag. Google does use it as the page description in your SERPs, if it matches the search query.

As I understand it, MC does a lot of experimentation with his site. He is also experiencing some supplemental problems.
Plus google isn't the only se out there.

Don't omit the meta description.

You need a unique one for every indexed page of the site.
