After a contest wraps up, most teams pull the same two numbers: how many entries came in, and how many people saw the post. Both are useful, but neither one tells you whether the campaign actually worked. A handful of quieter metrics usually say more.

Vanity Metrics vs. Signal Metrics

Impressions and total entries are vanity metrics — easy to report, easy to feel good about, and only loosely connected to whether the campaign moved the brand forward. Signal metrics require a bit more digging but tell you what actually happened to the people who participated.

Entry-to-Share Ratio

What percentage of entrants also shared the contest with someone else? This ratio tells you whether the campaign is genuinely spreading or only reaching people who were already in your audience. A low ratio usually means the sharing mechanic needs rethinking, not that you need a bigger prize.

Completion Rate

Of everyone who started the entry process, how many finished it? A gap between clicks and completions almost always points to friction in the form itself — too many fields, a confusing step, or a slow-loading page.

Return Engagement After the Contest Ends

Do entrants keep following, commenting, or opening emails after the contest is over, or does engagement drop back to baseline the moment the prize is announced? This is the clearest signal of whether a campaign built anything lasting or just rented attention for a week.

Sentiment, Not Just Volume

A spike in comments looks great on a dashboard until you read them and realize half are complaints about the entry process. Skimming actual comments, not just counting them, catches problems that pure volume metrics hide.

Building a Simple Metrics Dashboard

You don’t need specialized software to track this. A simple spreadsheet with impressions, completions, shares, and a 30-day follow-up engagement check is enough to compare campaigns against each other over time and see what’s actually improving.
