I think that if you have an important, impressive, well-known brand that you can boost your SERP click through rate and conversion rate by including your brand in the title. However, for a relatively unknown brand like mine there might be more valuable things to include in the limited title tag space.
These might include:
- free shipping
- kick ass price
- free ebook
- fast delivery
- biggest selection
- free beer
- a couple of extra keywords to pull traffic
All of these can elicit clicks and put the buyer in the mood to do what I want him to do when he gets on my site.
I am not out to compete with Microsoft on branding. I am out to get visitors onto my site and covert them - so I believe that in my situation the title tag space can be more wisely spent.
