5 Landing Page Mistakes That Hold Conversion Back

The five mistakes we find most often: a vague promise, a slow page, a long form, proof nobody can check, and measurement that was never installed.

5 Landing Page Mistakes That Hold Conversion Back

These five mistakes appear in almost every page audit we run. Four of them can be fixed without changing the design.

1. A vague promise

A headline such as "Digital solutions for your business" names no result and no reader. Replace it with a sentence that names the result, the reader, and a time frame when one exists.

2. A slow page on mobile networks

The Core Web Vitals thresholds are LCP 2.5 seconds, INP 200 milliseconds, and CLS 0.1 at the 75th percentile. Ad pages often fail LCP because of large images and third-party scripts.

3. A form that asks for too much

Every extra field adds a reason to stop. Ask for the fields your team uses in the first reply, then collect the rest in the conversation.

4. Proof nobody can check

Customer logos without a description of the work explain nothing. Replace them with one work example, a result number, and a contact name when the customer allows it.

5. Measurement that was never installed

Without form and purchase events, every fix becomes a guess. Install measurement before you switch the ads on.

Questions and answers

What should I fix first? Fix measurement, then speed, then offer clarity. That order keeps every later fix readable.

Does good design raise conversion? Design helps readability and trust. Design does not repair an offer that does not fit the reader.

What if ads are already running? Do not switch the ads off. Fix measurement first, edit the page during quiet hours, and record the date of each change.
