As other reviews have said, this tool takes a few weeks to show effects of updated metatags on page rank. However, so far, it's close to miraculous and the support is great.
Even without waiting for the free onboarding call, it was easy to install code and get it running on two sites. A suite of how-tos helped me add keywords and get into the basics. I was glad I did the easy setup since it saved a lot of time when I got to my onboarding call.
I ended up chatting with Dimar (vs the usual Vlad) and he set up all the rest, identifying opportunities and getting me going as he showed me how the tool works. The interface looks simple but there are many, many settings I would have no idea how to even touch. He then invited me to do another follow-up session in a few weeks to make sure I getting lots of value. I love AppSUmo developers who want customers to succeed rather than just buy the product.
He also explained that Nytro is a complement to Squirrly which I also bought.
