We have a site running on a main domain http://lightandspace.co.uk (60 indexed pages), and a blog running under the subdomain http://blog.lightandspace.co.uk (250 indexed pages)I currently have them running under two Analytics profiles and two Webmaster profiles. Just so traffic figures don't get muddled, is this bad practice from an SEO point of view?
Splitting blog and main site into two different webmaster and anlytics profiles - best practice?
google analytics;google search console
That's perfectly fine, your main domain and blog each have their own sitemaps and are uniquely verified domains so two domains in Webmaster Tools is fine and same with Analytics.
