Quick question: I've started an online marketing campaign for my company -- what would be the best benchmarks for measuring my success? Here's what I've got so far: --Google Analytics for main webpage and landing pages (to track # of visitors, clickthrough rate, bounce rate.) --Bit.ly to track the success of shortened links I post on twitter/facebook --# of leads generated over time --Google Webmaster Tools to track SEO efforts ...Is there anything I'm missing? Are there other benchmarks I could use to track the general success of my online marketing presence?
