The analytics service is very convenient; even a beginner can easily figure it out. The technical support is top-notch and quickly resolves issues. Although correctly connecting turbo pages in Direct is impossible, it's not their fault. The bid management tool is user-friendly, but the search for keywords needs improvement, as it sometimes takes a lot of time to find specific words, and the alphabetical sorting is incorrect. I also use call tracking and give it 4 out of 5; there are specific scenarios by geo that I searched for a long time. However, I feel that some calls are tracked incorrectly.
