16% CTR Rate With >32% Sign Up Rate, But No Integrations... Feedback Anyone?

Hey Everyone, as the title suggests we're a little stuck on one of our recent projects.

Without going crazy in depth on the tool, it's a grey hat social tool for Twitter.

Now unfortunately with Twitter's recent changes to their API we have been forced to come up with a new route for integrations. Our best / current approach is a via a Chrome Extension.

Often when we launch a new product that fits vaguely between white hat and black marketing, we will run some basic Google Ads to gauge the interest level of the keyword and tool itself.

STATS:
During approximately 12 days of testing, we were thrilled to see that we could average around 16% click-through-rate on the ads AND an absurd sign up rate of over 32%. Some days it even peaked closer to 45%. The majority of the signups were done via the easy to use Google Signup so the validity is solid.

Total Sample Set:

• 10-12 days
  -16% avg CTR
  -25 Signups at a 32-34% rate per day
  -1 Integration

CHALLENGE:
Where we are having issues is the integration. Great traffic, what seems to be high intent / interest in the product, and then at the final step... hesitation to integrate their Twitter account. We don't ask for credentials (username and pass) and instead just required the Twitter Cookie. On top of that the tool is free to use at the beginning.

Hoping we can get some feedback or hear from others that may have had similar challenges?
