High or low compared to what?
Your conversion rate is 12.6%, but this figure on its own is meaningless. So you need to compare it to something. That something will depend on what your solution is, e.g. is there an industry benchmark for the industry sector your solution works in?
The Click Through Rate is usually used by ad companies who want to see how well their ad attracts visitors and just measures the ratio of clicks to impressions of your page, email or advertisement, however clicking doesn't necessarily correlate with conversion.
Obviously looking at your two examples, the variation with the button is the clear winner because the original had no conversions.
The problem with a lot of these metrics like Click Through Rate (CTR) is they don't tell you 'why' someone clicked nor how they feel. Answering why questions is a User Experience thing, and there are much better metrics for measuring the user experience than CTR which is a marketing metric. People don't click ads in the same way few people watching television don't watch commercials.
