Most Saas companies seem to host their application on a sub domain rather than on a different domain. For example, the sales / marketing site might be hosted at example.com and the application is at app.example.com whereas we use example.com for our sales site and then example.net for our application.
Is this purely a personal preference thing or is there an advantage to hosting on a subdomain?
We were thinking mainly from an SEO perspective, does using the sub domain help? I assume it will make a difference on things like Alexa as it will show more traffic (I know Alexa is flawed) but also if anyone is linking to the application then it will be to a subdomain of our sales site which might help?
Curious to know if there is any benefit to using the subdomain option.
