Vill du ha mer kraft till domänen är /blogg ett självklart val. En subdomän ses som en unik domän och ger således ingen extra kraft, bortsett från ev länkkraft då du troligtvis ämnar länka mellan de olika domänerna.

Förr sågs en subdomän tydligen som en unik domän, men detta har förändrats de senaste åren. Jag tror dock precis som du att länkar till subdomänen inte per automatik stärker huvuddomänen, vilket är fallet om man lägger bloggen i en mapp.

Dominating Results with Domains and Subdomains
Say you decide to start a blog about widgets to share news and information about the widget industry to augment your original e-commerce widget site. How do you structure the blog? Do you place it as part of your original site, or do you place it on a subdomain or separate domain? Three common choices are:
- Existing site: widgets.com/blog/index.html
- Subdomain: blog.widgets.com
- Separate domain: widgetsblog.com
In the past, some search marketers may not have gone with the first option, to have it be within an existing site. That’s because it meant there was no opportunity to get more than two listings on the same page. Instead, historically, putting the blog on either a subdomain or a separate domain meant it would be treated as a completely different site, allowing the marketer to potentially pick up a third or even a fourth listing on the page.
Now that’s changing. 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.
It’s not that the “two page limit” now means from any domain and its associated subdomains in total. It’s simply a bit harder than it used to be for multiple subdomains to rank in a set of 10 results. If multiple subdomains are highly relevant for a query, it’s still possible for all of them to rank well.
