Micro-Mark: launching a paint line to a new YouTube audience

Owner-reported workflow, with analytics evidence from YouTube Studio.

1. Challenge

The campaign featured Micro-Mark Acrylic Paints through creator content for hobby painters and modelers, supported by paid amplification. The supplied materials do not establish the channel's pre-campaign audience size.

2. Work

The owner confirms the campaign included paid amplification. According to the owner, the team used SparkLine's video analysis to see which paint and miniature content performed well and to decide what to promote around the launch. This is the owner's description of the creative and promotion workflow; we have not measured how much of the result any single step caused.

Cropped YouTube Studio analytics for Micro-Mark showing 30.9K subscribers gained in the last 90 days, July 10 to October 7, 2026, and 24.7K monthly audience — YouTube Studio analytics supplied by Micro-Mark, cropped to remove account details.

What this does not show

These are channel-wide numbers during the campaign period, not a paid-only or SparkLine-only result. We do not have starting subscriber counts, ad spend, sales, ROAS, per-video performance, attribution lift, or a customer quote, so none are claimed.

Public reviews of the product

Five public YouTube reviews and demonstrations of Micro-Mark paints. They are content about the paints, not endorsements of SparkLine; we do not claim the creators' commercial relationships or show per-video performance statistics. Thumbnails are official video previews, not stills from the moment of playback. Players load only when you click.
