For many large sites, it may not be immediately clear how to optimally structure your Dragon Metrics campaigns. A typical question is whether each section of the site (e.g. subfolder or subdomain) should be tracked as a separate campaign.
While there is no one-solution-fits-all, take a look at the following statements that are true for you, and you will likely be able to find the right structure for your situation. In most scenarios, unless there's a good reason to use multiple campaigns, it's best to use one campaign per root domain.
Ask yourself if these statements apply to your situation to see what's the best setup for you:
"I have two or more multinational sites targeting separate countries and languages"
See this article for more specific guidance on multinational sites.
"All keywords should track all URLs on my site, and should all track the same search engines and countries"
Use a single campaign. There's usually no clear advantage to using multiple campaigns in this scenario.
"I want to track different segments of keywords on different search engines"
This can be done within a single campaign by enabling keyword-level search engine tracking.
"I want to find the competitors for each part of my site separately"
"I want to track different keywords for different parts of my site"
If you would like to track different keywords for different parts of the site, there's one more question to ask:
If the "wrong" part of your site ranks for this keyword, do you want to show that there are no rankings at all for this keyword? Or do you just want to be able to see that the "wrong" part of your site is ranking for this keyword?
Show as no ranking: In this case, use separate campaigns for each section.
Show with ranking, but report that it's not the right section: Use one single campaign, but set up Preferred Landing Pages for each keyword and add each section of the site as a competitor.
"I want to compare detailed reports by section"
Campaigns are meant to be independent of each other, so most reports can only view a single campaign at once. While it's possible to compare high-level data between campaigns, if you want to compare different parts of a site at a detailed level, you'll need to keep them as a single campaign.
Inside a single campaign, you can compare sections of the site by adding each subfolder/subdomain section as competitors and/or by tagging keywords by section.
"Each subdomain is owned or managed by a completely separate entity"
If each subdomain is owned by a different organization or is structured in a way that each subdomain should be viewed as a completely independent site, use multiple campaigns for each subdomain you'd like to track.
"I want to keep each section of the site completely separate"
If each part of the site should be viewed as a completely independent site and never have their data mingled together, use multiple campaigns for each section of the site you'd like to track.
"I want to assign some users to only be able to view or manage some country sites"
Use multiple campaigns. Users can be given access only to specific campaigns, but if all sections are using the same campaign, this will not be possible.
"Each section of the site has its own Google Analytics property or Google Search Console site"
Use multiple campaigns. Each campaign can only be set to a single Google Analytics property or Google Search Console site.
"Each section is actually a separate root domain"
It's usually best to use multiple campaigns, one for each root domain, since each campaign can only track URLs on one root domain.
If each domain still tracks the same keywords and search engines/countries/languages, you could still use a single campaign and add each domain as a competitor to compare performance. However, this method will only work for rank tracking, as it will not be possible to track site audit, backlink, Google Analytics, and Google Search Console data for any domain that doesn't have its own campaign.
