The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
Overall, the program can redirect specified URLs, but does have a few key app errors. However, customer service appears to be non-existent. I've reached out to this service provider on numerous occasions using different means (support screen, emails, etc.) to secure answers to a few questions not covered well in his FAQ and also to address a few key app errors (e.g., Dashboard red bar shows 399 missing link 404 errors, but detailed reporting function only lists 100 missing link URLs -- critical to identifying redirects so that they can be fixed), but have never heard back even once. I've given this service provider 2 stars only because without a means to identify the full list of problematic urls (ie. 404s) in a single listing am not getting the needed functionality to run my business.
It's unfortunate that they try to up-sell you on additional products that you really need to manage your 404s. I paid $30+ dollars, and did not expect to have to pay $4/month for a key feature (the ability to see 404s you might have missed). Sorry, but that's a pretty big fail in my book.
