We take a look at LeadDoubler vs Riddle this week. Both offer marketers some strong lead generation and interactive content features – which quiz maker should you choose?
Right, there’s no easy answer – you have your own marketing needs. But we’ll provide a detailed overview of both the LeadDoubler (AKA ‘Lead Doubler’) and Riddle quiz creator platforms.

There’s a bunch of quiz makers out there, for the simple reason that quizzes are awesome at converting casual browsers into active and clicking visitors. And best of all – once they’re engaged with your quiz, it’s a natural next step to ask them for their email address and other info, so quiz takers become leads and potential customers.
(Okay, okay – so in the interests of fairness, we should point out that we’re obviously fans of Riddle… this post is from our blog, after all. But both are great platforms for marketers – read on to see how each compares in everything from customization to lead generation and content types. You’ll be much more confident in deciding which – Lead Doubler / LeadDoubler vs Riddle – will meet your own particular use case.)

Quiz engagement vs lead generation
Let’s start with a quick overview of how quiz makers can help marketers – before we dive in and explore LeadDoubler vs Riddle in depth.
As we mentioned at the top, marketers turn to quiz makers for two goals – increasing engagement and collecting leads. It’s a big brief – so you’ll see that every quiz maker has their own philosophy about how to best tackle this challenge.
About engagement – we’ve probably all seen sites use personality tests, quizzes and other interactive content to get their audience involved, staying longer, and sharing their results on Twitter, LinkedIn, Facebook and more.

Quizzes and lead generation go together – like Batman and Robin, Frodo and Sam, or cookies and milk. As we mentioned above, quizzes, lists and polls are centered around getting your audience answering questions. Adding an optional lead generation form works well here – your audience is already in the ‘answering’ mindset, and keen to see their results.
This is a great chance to show each user a chance to sign up for newsletters, enter a contest, or receive a special offer. We’ll compare Lead Doubler / LeadDoubler vs Riddle’s capabilities below – the best marketing is scalable and automated.
A good quiz maker will let you send each lead’s information data to your email tools to trigger follow up marketing messages so you can convert leads into happy, paying customers.
LeadDoubler – overview
LeadDoubler is a Danish company that’s started back in 2008. They emphasize customizable calculators (“How much can you afford in a mortgage?”) as well as quizzes as the best tools to qualify potential customers.

One of the main differences in LeadDoubler vs. Riddle is this focus on calculators – it’s an interesting niche because a lead is volunteering their key buying criteria. LeadDoubler has also included lead generation capabilities to follow up on each sign up – with connections to HubSpot, Pardot, Pipeline, and MailChimp.

However, as one of the oldest tools out there, our review shows they haven’t been upgrading the platform to keep abreast of the latest trends and technology.
For example, they offer only a basic ‘yes/no’ quiz along with their calculators – compared the wider range of personality tests, branching logic quizzes, polls, and more with Riddle.
Riddle – overview
Riddle has a different philosophy – we offer a growing range of quiz types (14 and counting) to help meet marketers’ content needs. This gives you a lot of flexibility to create the right quiz for your use case. And trying a variety of quizzes will keep things fresh for your audience so they don’t get tired of you presenting the same quiz type over and over again.
This approach carries over to lead generation. Looking at LeadDoubler vs Riddle, we’ve made it easy to connect your quiz with over 1,100+ other marketing tools – from ClickFunnels to SalesForce – with no coding required.
