The UI/UX of this product has been designed very well with ease & simplicity in mind for everyone to use it without any struggle at all! -The ability to track leads from multiple channels like Facebook ads etc.- Automation features are really good as well:- Helps you understand your campaigns much better than ever before.- Easy integration into other platforms (like Zapier). Nothing specific I dislike about UltimateLead so far but there might be something which we haven't figured out yet though they do have great customer support team who will help us solve our problems instantly whenever required or asked by them! Great tool if used properly can definitely improve CTRs / conversions dramatically. We were struggling earlier when converting more visitors through facebook ad accounts due to their inability to create custom landing pages easily.
