Excellent tool to know the natural positioning of a website's keywords.
You can check the history of each word over the last month, which allows me to analyze the effectiveness of the modifications made on the website.
Although it has a free version, if you use it professionally to analyze your clients' websites, the paid versions are quite economical compared to other similar tools.
It is easy to use and configure, and available in my language, which makes my work much easier.
So far, I haven't needed to contact technical support, so I can't evaluate it, but this is also a good sign of its good performance and ease of use. Review collected by and hosted on G2.com.
Some functions, despite having a payment plan, are only available with higher plans. This is not really an inconvenience, as it is remedied by acquiring a greater number of clients on my part. Review collected by and hosted on G2.com.
