What actually makes a website convert

22 July 2026The Agency

The short version

Most conversion problems on business websites are not caused by the things people argue about online. They are caused by four ordinary things: a slow first page, a fuzzy proposition, forms that ask too much, and pages that do not match what the visitor came to do.

Speed is not optional

Every extra second of load time measurably reduces enquiries. Aim for a Largest Contentful Paint under 2.5 seconds on a mid-range Android phone on a 4G connection — not on your office WiFi. Compress images, defer non-critical scripts, and be honest about what really needs to be on the first render.

Say clearly what you do, for whom, and where

Within five seconds of landing on your home page a visitor should be able to answer:

  1. What is this company?
  2. What do they do?
  3. Is this for someone like me?
  4. Where are they based?

If any of those take more than five seconds, you have a proposition problem, not a design problem.

Ask for less on forms

Every field on an enquiry form loses a percentage of respondents. Ask only for what you genuinely need to reply — usually a name, an email, and a short message. Everything else can be asked in the follow-up conversation.

Match the page to the intent

A visitor searching "web designer near me" wants proof, location and a price signal. A visitor typing your brand name wants a login or a phone number. The same home page cannot do both jobs. Landing pages are how you match content to intent without breaking your main navigation.

Measure the right thing

Track enquiries and qualified conversations, not sessions or bounce rate. If your analytics does not tell you whether last month brought more or fewer real enquiries than the month before, it is measuring the wrong thing.
