Google Analytics and Webmaster Tools
Webmaster Tools data may differ from the data displayed in other tools, such as Google Analytics. Possible reasons for this include:
- Webmaster Tools does some additional data processing—for example, to handle duplicate content and visits from robots—that may cause your stats to differ from stats listed in other sources.
- Some tools define "keywords" differently. For example:
- The Keywords page in Webmaster Tools displays the most significant words Google found on your site.
- The Keywords tool in Google Adwords displays the total number of user queries for that keyword across the web.
- Analytics uses the term "keywords" to describe both search engine queries and AdWords paid keywords.
- The Webmaster Tools Search Queries page lists shows the total number of keyword search queries in which your page's listing was seen in search results, and this is a smaller number.
- There may be a lag between when the numbers are calculated and when they are visible to webmasters—although data gets published in intervals, we are continually collecting it.
If you can no longer see a search query you saw recently on the Webmaster Tools Search Queries page, make sure you haven't filtered the results by country or type of search.
Webmaster Tools aggregates query information, and displays search queries once the count of each query reaches a certain threshold. Your logs may show a particular query as having a high rank for a certain day or period, but that query does not appear in on the Search Queries page. If the query continues to be a top referrer, however, it will move to the top of our aggregate results and will appear on the Search Queries page.
Also, Webmaster Tools stats show only search queries from Google. Your log files may combine search results from all search engines.
