There’s no one tool that does it all. I have found that with all products, there are inconsistencies between click throughs and Google Analytics and Twitter native analytics. I have no idea what’s going on. Google Analytics is consistently lower.
After switching from Spredast to Social Hub, did see a different baseline. Spredfast’s numbers were more conservative. Spredfast used Bitly, Social Hub have their own URL shortener. We end up using Google analytics for a lot of reporting and social reporting tool for slicing dicing and trend analysis.
