: How to make Google consider subdomain as part of the main website in SEO? I have a well ranked website on Google and Bing. In the last few months I've been feeding a blog for my webpage

@BetL925

Google will automatically treat subdomains as part of the main site when:


They have related content
They are written by the same person or company
They link to each other


From Vanessa Fox, an ex-Google employee:


Google is no longer treating subdomains (blog.widgets.com versus widgets.com) independently, instead attaching some association between them. The ranking algorithms have been tweaked so that pages from multiple subdomains have a much higher relevance bar to clear in order to be shown.


Here is a list of things you can do from Do subdomains help/hurt SEO?:


Link between the subdomain and the main site in the navigation menu, and visa-versa.
Put the same copyright statement on the bottom of each
Link each to the same terms of service, privacy policy, and contact page
Use the same logo on each
Use the same look and feel: colors, fonts, and layout
Add the subdomain to the same account in Google Search Console
Use the same Google Analytics and adversiting accounts (such as AdSense) on each
