So I gave Aeden 10 different keywords, (which yes, is quite a few!), and opted to wait several days before leaving a review so I could gague the results.
Half the keywords given had over 100,000 monthly searches per month, one of them even having over 200,000 - so it wasn't like I was expecting any real movement. Just wanted to dilute my link profile a little.
So far, of the 10 keywords given, 6 have shown positive movement, 1 keyword (130,000 monthly searches) even getting position #21 from position N/A, and another (the other 130,000 monthly searches) keyword hitting #37 from N/A. The other 4 out of 6 keywords are all sitting between #50-#60, and the remaining 4 that haven't shown improvement, are sure to show (even a little!) improvement in the near future.
Aeden has also been easy to get in contact with, and generally seems like a great guy to do business with. I would recommend using this service to dilute your link profile with Q/A links, and even go so far as suggest using it if you haven't already.
All in all; would use again. Definitely. Good quality service, Aeden, keep it up.
