I like the fact Raven includes all the crucial information and tools so I can make the best informed decisions for my clients. It makes my job a lot easier by having everything in one place, and inter-connected.
Raven has probably some of the best reporting software available. I am super excited that they recently updated it, so it's even better now. By far the best that I have seen so far.
The other 2 tools/features that I like is the backlink reporting and tracking. It makes it super easy for me to find out what my "competitors" (I like to think we are all friends helping each other) are doing, and what would be the best link opportunities for myself and clients.
The other one is the site auditor. I have used other software that is almost just as good. But again, when it comes down to the details, and then putting it into a easy to understand report for my clients, Raven Tools is second to none.
Overall, I think it is because of the reporting, and how everything is inter-connected that makes me stay with Raven Tools
What I dislike about Raven Tools is the rank tracking. They use Google Webmaster Tools to supply this information. So it is accurate. However it isn't as clear and nice as other tracking software. This is understandable since Google does have requirements for those that want to use Google's Adwords API. You can look into this for more information. So it is understandable why they dropped the old ranking tool, it still is unfortunate, and is the only thing that I dislike.
I am solving the problem of having multiple software trying to do one thing: Find a solution for my clients to increase their rankings, traffic, conversions.
The amount of hours I have saved, I can't even say. All I know it is a lot. And it also makes my company reputable by having such nice looking and informative reports to send to my clients, without me spending countless hours creating them.
