As you know, the queries used to find your website in search results can change over time. Your website content changes, as do the needs of all the busy searchers out there. Whether the queries associated with your site change subtly or dramatically, it’s pretty useful to see how they transform over time.
Recognizing this, Top Search Queries in Webmaster Tools now presents historical data and other enhancements. Let’s take a closer look:
Up to 6 months of historical data:
Previously we only showed query stats for the last 7 days. Now you can jump between 9 query stats snapshots ranging from now to 6 months ago. Note that the time interval for each of these snapshots is different. For the 7 day, 2 week, and 3 week snapshots, we report the top queries for the previous week. For the 1 to 6 month snapshots, we report statistics for the previous month. And still others of you who log in may notice that you don’t have query stats data going back to 6 months ago. We hope to improve that experience in the future. 
Top query percentages:
You might have noticed a new column in the top query listings. Previously we just ranked your query results and clicks. While useful, this didn’t really tell you to what extent one query was ranked higher than another. Now we show what percentage each query result or click represents out of the top 20 queries. This should help you see how well the result or click volume is distributed in the top 20. Full article.
