Quickly spot changes in market share and performance with the new period-over-period view on the Market Players page.

Our Keyword List Generator in Demand Analysis just got even better thanks to a revamped suggestion pop-up. We’ve made it easier than ever to create a keyword list by enhancing both the interface and the suggestions themselves. Now, keyword phrasing and relevance scores are seamlessly combined into a single, optimized list—helping you find the best options in just one click.

Easily identify and compare shifts in marketing channel performance with our updated Marketing Channels tool. Analyze traffic period-over-period, with detailed breakdowns for both mobile and desktop. Choose how you view channel distribution changes—by percentage or volume—based on your needs. Then, decide whether to analyze the competition by “domain” or by specific “channels,” depending on what information you need.
