Hello. This product receives regular updates to ensure it continues working properly over time. These updates are shipped out routinely through built-in automatic updates, which you can see from your admin panel.
The latest updates was on May 24 and included some awesome changes to the speed test tool, allowing you to test at different locations. Before that, we had an update on May 17 which maintained compatibility with Alexa tools after their newest redesign.
The most important part of any SEO tool script is consistent updates to ensure it remains working properly over time - and I have proudly maintained regular updates to this script since 2016.
I would encourage you to review your admin panel and see that in fact, you are receiving regular updates.
There is a major feature update planned for SEO Studio that has been heavily, but this is only a planned update; you should only buy this script as-is for the features it has at the time.
Unfortunately this is out of my control, as I am a full-time student and my available time to work on this update is often limited and very unpredictable. Despite that, I still maintain regular updates to SEO Studio's current iteration.
Feel free to contact me via my profile or comments if you have any questions.
