The Safari issue had me tearing my hair out for some time...platform testing, comparison, studying...until I discovered one VERY IMPORTANT thing...
Just as Firefox has the pre-loaded popular sites when a new tab is opened, so does Safari. The difference is that Safari does not use a cached version of your page like FF does - it re-loads it EVERY TIME the user attempts to open a new tab. This counts as a unique (and non-converting) visit. When digging into Safari users, I found some very strange things - lots of very high screen resolutions, lots and lots of people visiting and re-visiting. I discovered these were "power users" who had us saved in their tabs. They didn't necessarily visit the site every day (being ecommerce and all), but wanted to know where to go for their purchase. Our Safari conversion rate is ~1/2 of FF and ~35% less than IE. Not too bad, considering the circumstances.
Disappointing to find out there wasn't a "magic bullet" to fix with Safari users, but relieved that there was an explanation behind the lower conversion rate.
