That is exactly what I always try to explain to people: the first thing you need is expertise. And if something goes wrong YOU are the one to blame, not the software you used. Software is to help you to do monotonous boring work, create and send your reports. It is a thing to help you. BTW the one I voted for is WebCEO
I agree about WebPositionGold being very good for reporting. It may have the best reporting features of any software out there. However, the GUI on the rest of the program is ugly and the software in general is not as good in some areas as other proggies are. I also use IBP for the other stuff that WPG isn't as good at.
Thank you all for your votes, now I think I need to download trials and to check them. I will try IBP and WebCEO. And I am a little bit afraid of using WebPosition as it is mentioned in Google Webmaster Guides.
