Before You Kill That Mobile Subdomain…
Most SEOs I know hate sites with separate mobile URLs. They served their purpose back in the early days of mobile browsers, but over time the maintenance overhead combined with the SEO uncertainty brought on by having two different sets of near duplicate URLs has caused many of us to advocate for migrating to a single set of URLs for both mobile and desktop.

Fortunately Sistrix has a handy tool to estimate organic traffic to subdomains. Let’s look at how some big e-commerce sites have fared with M-dot migrations:
