Frequently Asked Questions
Do subdomains affect SEO?
Google treats subdomains as somewhat separate entities from your main domain. For most small businesses, keeping everything under your main domain (using subdirectories like /blog/) is better for consolidating SEO authority.
Can I have multiple subdomains?
Yes, you can create as many subdomains as you like. Common uses include blog.yoursite.co.uk, shop.yoursite.co.uk, or staging.yoursite.co.uk for a test version of your site.
Do subdomains need separate hosting?
Not necessarily. A subdomain can point to the same hosting as your main domain, or it can point to a different server entirely. Your developer can configure this based on your needs.
