We're an SEO agency, providing search engine marketing solutions for Fortune 500 companies. We have to deal with lots of different clients and industries. My 3 favorite features are: 1. Keeping track of clients is a breeze. 2. We can assign team members to different projects and tools. 3. Seoprofiler automatically sends SEO reports to our clients. Bonus feature: All reports look like we did them by hand.
We use Seoprofiler ten hours a day. Without it, I don't think our agency would be near as effective.
