Sherpas: Smart SEO

This is one of the best App that I have installed recently. It is easy to use and understand, with just a few clicks, all was optimized in timely manner. I like it. So far so great. I didn't even use their support, there was no need. All was clear to comprehend. And I am on their free plan. Amazing! Good job guys. Thank you!
Update: It has been three months now, and I didn't change my mind, they are still the best, helped me a lot with all of my issues. Still up to date, still very supportive, and do the most things for free. I am impressed by their willingness to support and advice, super fast. It is amazing. Highly recommend. Basic plan is awesome, too, and very affordable. Thanks guys, huge thanks!
