Google Trends now tracks website traffic, which is great news (previously, Google Trends only showed search trends). Personally, I’m glad to see this new feature, because:

Alexa.com is not very accurate.

Compete.com is more accurate than Alexa, but only uses U.S. traffic and only shows traffic for the past 12 months.

Google Trends for websites has the following advantages

• Probably accurate (although I can’t prove that)
• Allows you to look at traffic for various time periods
• Allows you to look at global traffic, or look at traffic by specific countries

Almost all Google’s products are fantastic, in my opinion, and this new feature is a great addition to Google Trends.
