As a consultant who helps companies with their search presence, I found the tool through a client who recommended it and another competitor. After vetting the two tools, I found that Topic had a superior product both from a features and usability standpoint. Since then, I've optimized a number of drafts using the tool and found that it's saved me time and gives me clear, measurable ways to improve the work I do for my clients. I mainly use the Content Grader to optimize drafts to make sure we didn't miss something obvious compared to the competition. Review collected by and hosted on G2.com.
It would be great if the content draft connected to analytics after a given piece of content is published, however that currently is not a feature offered by Topic (or any of the competitors as far as I know). I've given this feedback to the Topic team and they are considering adding it into the product roadmap, so that's encouraging. Review collected by and hosted on G2.com.
