What is a Set?
A Set is the pool of influencers that a Competitive Analytics report draws from. Every report is built on top of a Set. It defines which creators are monitored when measuring brand performance.
Sets are scoped by:
Geography:
Country: profiles in a specific market (e.g. profiles in France with 1M+ followers)
International: profiles across markets (2M+ followers)
Industry: influencers active in a specific vertical (e.g. Beauty, Fashion, Lifestyle)
A report can combine both, for example, Beauty influencers in France.
Please note: Competitive Analytics reports display influencers with a minimum of 10k followers. Lefty tracks data below this threshold inside campaigns, but not within a Competitive Analytics report.
What are Brand Definitions?
Brand Definitions are the tracking parameters that tell Lefty what to count as a mention of a brand within a Set. When an influencer in the Set posts content matching a brand's definition, that post is attributed to the brand in the report.
A Brand Definition can include any combination of:
Mentions: the brand's @handle(s) on each platform
Hashtags: branded or campaign-specific hashtags (e.g. #BrandName, #BrandCampaign)
Keywords: non-generic terms associated with the brand that may appear in captions
Brand definitions are set up to be exhaustive across platforms with brand-relevant parameters, ensuring all meaningful content is captured from the start.
How Sets and Brand Definitions Work Together
A report's output is the result of combining both layers:
The Set determines which influencers are monitored.
The Brand Definition determines which posts from those influencers are attributed to each brand.
If a post is published by an influencer outside the Set, it won't appear in the report, even if it mentions a tracked brand. Likewise, if a post doesn't match any parameter in a brand's definition, it won't be counted for that brand.
