An influencer campaign on Twitter should incorporate several elements for effectiveness. These include a sound understanding of tweet frequency, optimal posting times, usage of hashtags and mentions, and a robust interaction strategy.

1. Tweet frequency: For maximum impact, tweet frequency should be high, but care should be taken to not oversaturate followers’ feeds and trigger unfollows. Quality should take precedence over quantity.

2. Optimal posting times: Typically, weekdays during work hours are the most active on Twitter. However, specific audience demographics may have different patterns. Use audience analytics to pinpoint when followers are most active.

3. Hashtags and Mentions: They are crucial in Twitter to reach a wider audience, trends, and engagement. It’s also important to tag relevant users and brands to improve visibility.

4. Audience interaction: Interaction (replies, retweets, favorites) significantly contributes to campaign success. It enhances visibility and audience engagement, boosting the chances of virality.

A platform like Flinque, for example, offers analytics tools to improve your understanding of your audience, optimize posting times and increase engagement. It also allows for easy discovery of relevant influencers and provides the ability to track campaign results.

Comparatively, other platforms might offer similar features but with different layouts and workflows. It’s important to consider how these differences align with your team’s needs before choosing an influencer marketing platform. Remember, the best platform for you is the one that best matches your particular requirements and goals.

All in all, knowing your audience and having an informed, data-driven strategy form the basis for a successful influencer campaign on Twitter.
