When you look at too many numbers, it's hard not to compare your campaign with others and judge it accordingly. But it's important to keep in mind how many different factors make up the conversion rate.
For example, the reason Capterra's average conversion rate is higher than other channels could be because we target software buyers. This means that more people come to us with an existing interest in buying. As a result, the number of web visitors who click through and sign up as leads is correspondingly higher than with AdWords. This doesn't mean that your AdWords campaigns are performing poorly. It just shows that there are differences in traffic and leads that are reflected in the data.
Judge the performance of your campaigns based on your success criteria and goals, not on the numbers and korea telegram data averages in your industry. I want to use this data to give you an idea of what the numbers look like for similar campaigns. But that is not an answer to the question of how well your campaign is performing. Only you can judge that for yourself.
