If you have created a Clickfunnel step and noticed that the final URL has added extra numbers and digits after the words, it’s because this word already exists in a step for another funnel. For example if you created test.com/hello and Clickfunnel has changed the URL to test.com/hello345353. This is because you have another step somewhere that is using the /hello URL.
To overcome this and stop Clickfunnels from adding extra letters and numbers you have the make the step name unique. EG test.com/welcome. If Clickfunnels can see that no other step is names “Welcome” then it won’t add all that extra stuff after the final URL.
