In the caveman days, scent played a big part in who you wound up with, but we’ve evolved since then, and most of us now prefer the latest perfume and/or cologne from some celebrity. The principles of attraction have also evolved. They now include attracting people online, on networks such as Facebook. But without online olfactory aids available (at least not yet) to help you understand who you are attracting to your business page, you could be totally ignorant about who you’ve ended up with. Thankfully, Facebook has developed Insights to sniff out details from anyone visiting your page.
