What do you like best?
The data sets available within searchmetrics are the most comprehensive and deep datasets available for enterprise SEO's. Quality of data is critical when performing SEO on large websites, in competitive industries. The customer services teams are very helpful, and really dig into your questions, and become partners in your success.
What do you dislike?
The only negative I see with Searchmetrics is that it can take a few weeks to get familiar with the interface, and learn how to navigate the deep depths of rich data. This process is greatly assisted by a team of great customer success specialists.
There is one element of searchmetrics which I feel could be better and more intuitively setup out of the box. Many users like to just see some pre-populated reports, go get a general baseline of performance. The flexibility and depth of customization offered within the platform is amazing, but it requites a little setup out of the box. While is strategy is desired for more advanced users, its not quite as easy for mid-level SEO's.
Recommendations to others considering the product
Don't just get a trial, without investing significant time in getting used to the platform. Its a "masters level" tool, and will take you time to get used to it, if you do not have at least a few years of SEO experience.
