While both niche and mainstream influencers can execute effective campaigns, their strategies might differ due to their varying audience sizes and engagement levels.

1. Audience Size and Engagement: Niche influencers typically have smaller, but highly engaged audiences. They tend to have higher engagement rates because they focus on specialised subjects, leading to more dedicated followers. Mainstream influencers, on the other hand, boast larger follower bases but might have lower engagement rates.

2. Content Creation: Niche influencers often emphasize authenticity and passion in their content. They may collaborate closely with brands to create original, context-rich content that resonates with their followers. Mainstream influencers, with their vast audiences, might focus more on mass-market appeal.

3. Brand Alignment: Niche influencers are more selective about brand partnerships, aligning only with brands that resonate with their focus area. This could lead to more successful campaigns as their followers trust their recommendations. Conversely, mainstream influencers might partner with a wide range of brands, given their diverse audience.

4. Campaign Reach and Budget: Mainstream influencers tend to command higher budgets due to their wider reach. Conversely, while niche influencers might require a smaller budget, brands might need to work with many such influencers to attain a comparable reach.
