Creative Effectiveness Lions

The Creative Effectiveness Lions celebrate the measurable impact of creative work.

Introduction

The work should demonstrate how an effective strategy rooted in creativity has met its chosen business objectives, generated positive customer outcomes and driven sustainable business impact over time.

The history of the Creative Effectiveness Lions

Launched in 2011, the Creative Effectiveness Lions are defined by a demanding entry process involving a detailed dissection of the work, focused largely on articulating demonstrable results. It’s a requirement that often results in agencies and their clients collaborating on submissions – a process that is educational in itself.

Initially this Lion was open only to shortlisted and winning entries from the previous year. However, it was acknowledged that the business impacts of creativity take longer to be proven over time and so the eligibility period was extended to work that won or was shortlisted within the previous 3 years.

In 2021 the Lion and its entry form were redesigned to reflect the principles of the Creative Effectiveness Ladder LIONS created in collaboration with WARC.

Guidelines to Entering

What kind of work can be entered?

The Creative Effectiveness Lions is open to any organisation that has won or been shortlisted for a Cannes Lions Award in 2023, 2024 or 2025 that can demonstrate that their creative work has driven results and achieved commercial success for a brand.

The entry can come from a company credited on the shortlisted or winning work. So even if you were not the original entrant, because you were involved and credited on the work you can submit what has happened since winning as part of a Creative Effectiveness entry.

What are the judging criteria?

A number of criteria will be considered during judging, weighted as follows: 25% idea; 25% strategy; 50% impact and results.

Eligibility

To be eligible your work must have won or been shortlisted at Cannes Lions in 2023, 2024 or 2025.

Is there a limit to how many times I can enter?

The same piece of work can be entered up to four times in Creative Effectiveness.

Exception:

  • The same piece of work may only be entered once in ‘A. Creative Effectiveness: Sectors’.

What do I need to provide with my entry?

To enter, you’ll need to complete an online entry form, which can be found on the Cannes Lions entry site. In the ‘Written Explanation’ section, you’ll be asked to provide the Jury with everything they need to know about your work.

You’ll also be able to submit optional supporting materials to provide additional context with your entry.

Subtitles are highly recommended on all case films, films, demo films and original content.

Detailed information outlining the entry process can be found on A Guide to the Cannes Lions Awards.

More information on the rules for entry can be found on the Summary of Key Rules for Entering and the handbook for our new Integrity Standards can be found on the Integrity Standards.

What if I don’t have all the details right away?

Don’t worry – you can fill in the form in any order and save your progress at any time while it’s still in the pending stage. However, please only check out when your entry is 100% complete as no changes can be made to your entry once you’ve clicked “Submit” and “Checkout”.

The Written Submission

Here’s the questions you’ll be asked regarding your work.

To start your entry to the Creative Effectiveness Lions, go to our Awards page.

The Jury will refer to the written explanation you provide throughout the judging process. Our advice is to provide as much relevant detail as possible.

When answering the following questions keep the main element you’re trying to celebrate in mind (e.g. the storytelling, the strategy, the craft, the use of data).

The bullet points under each question are prompts designed to guide your thinking, based on the factors the jury will be considering when reviewing your work. You might not need to use them all, and that’s totally fine. They’re there to help you consider what’s most important in your work.
