Google Trends is useful if you want to compare the popularity of two or more search terms, but it can't generate lists with popular search terms from a category, like in Google Zeitgeist. You need to provide the search terms and adjust them until you found the most popular keywords, but this is time consuming and ineffective.
Google Insights for Search categorizes searches and shows popular queries from a category like Telecommunications, popular queries from a certain country or from a specific date range. You can use it to find answers to questions like:
* what are the most popular cars in the US this year?
* what are the top searches in France for the past 30 days?
* which file sharing services were the most popular in 2007?
* what was the distribution of the Google searches for iPhone in the US last month?
* what are the top searches related to Google this year?
The service has been created with the advertisers in mind and has many potential business uses: examining seasonality, comparing synonyms, finding regions that are interested in a certain product.
To group multiple keywords, separate them using +. To compare two or more keywords, click on "Add search term" or separate the keywords using a comma.
