How to improve your small business website's conversion rate

Work out your conversion rate, find where visitors drop off, and fix one step at a time.

Last reviewed 22 October 2026 · Written by the Acing team

Start with the maths

Your conversion rate is the share of visitors who complete the action you want. Divide completed actions by visits, then multiply by 100.

Example: 40 enquiry-form submissions from 2,000 visits is 2%. Pick one action per page. A product page converts when someone buys. A services page converts when someone sends an enquiry or books a call.

Decide your time window and keep it fixed. Compare like with like: this month against last month, or this quarter against the same quarter last year if your trade is seasonal. Split the figure by traffic source, because visitors from search, social and email behave differently.

Do not chase an "average" from an article. Your own baseline matters more, and it is the only number you can act on. If you want to see what a small rise is worth in pounds, the free conversion rate calculator works out your rate and the revenue effect of improving it.

Set up measurement in Google Analytics 4

You cannot improve what you do not count. Google Analytics 4 (GA4) records activity as events. You then flag the important ones.

Key events, not conversions

Google renamed the old GA4 "conversions" label to "key events". Per Google's help pages, a key event is an event that measures an action important to your business. The word "conversion" now refers to actions used to measure and optimise ad campaigns, and it needs a linked Google Ads account. See Google's explanation of conversions versus key events.

For most small sites, key events are all you need. The usual route is: event, then key event, then (only if you run ads) conversion.

Mark your first key event

In Admin, open Events under Data display. You need at least Editor access on the property.
Find the event, such as a form submission, and click the star beside it.
Or choose Create event, name it, and switch on Mark as key event.

Marking only applies from that moment. It does not rewrite history, and standard reports can take up to 24 hours to show it. A standard property allows up to 30 key events, so be selective. Details are in Google's guide to marking events as key events.

Find the leak with a funnel

Google documents a funnel exploration for lead forms. Steps are: home page view, form page view, form_start, then form_submit. The drop between steps shows where people give up. The walkthrough is in Google's lead generation form report guide. Change one thing, wait a few weeks, then compare.

What you want to know	What to track	What it tells you
Are people finding the form?	Page views of the form page	Whether navigation and links work
Do they start it?	Form start event	Whether the offer and page convince them
Do they finish it?	Form submit event	Whether the form itself is the problem
Which channel brings buyers?	Key events by source	Where to spend time or money

Make pages fast enough

Slow pages lose visitors before your message lands. web.dev defines three Core Web Vitals. Each is judged at the 75th percentile of real page loads, split by mobile and desktop. Read the full definitions in web.dev's Web Vitals overview.

Metric	Measures	Good
Largest Contentful Paint (LCP)	Loading	2.5 seconds or less
Interaction to Next Paint (INP)	Responsiveness	200 milliseconds or less
Cumulative Layout Shift (CLS)	Visual stability	0.1 or less

INP replaced First Input Delay. It looks at every click, tap and key press, not just the first one.

Check yours for free

PageSpeed Insights needs no setup. If your site has enough traffic, it shows the last 28 days of real-user data for mobile and desktop. Google Search Console groups pages by type, so you can spot a problem template. web.dev's guidance for non-developers is in Optimize Core Web Vitals for business decision makers.

Fixes you can ask for today

Upload web-sized images, not print-quality files.
Avoid carousels and video at the top of key pages.
Remove plugins, widgets and old tracking tags you no longer use.
Load maps and similar widgets only on pages that need them.
Reserve space for images so the page does not jump while loading.
Show cookie banners as overlays rather than pushing content down after load.
Keep your platform and plugins updated.

Re-test after each change. Speed work can regress quietly.

Write calls to action people can follow

Each page needs one main next step. Two competing buttons halve the clarity.

Use a verb and a result: "Get a quote", "Book a 15-minute call", "Download the price list".
Place the button where the reader has just learned why they need it. Repeat it at the end of long pages.
Say what happens next: "We reply within one working day" only if that is true.
Make it visually distinct from everything else on screen.

Test one change at a time. Your own funnel will tell you whether a new button label helped.

Build trust before you ask

A stranger needs reasons to believe you. Use only what is real and checkable.

Your full business name, address and phone number, plus a registered company number if you have one.
Clear prices, or a clear way to get one.
Delivery, refund and cancellation terms in plain English.
Real photos of your work, premises or team.
Reviews you can link to on an independent platform, used with permission.
Accreditations and memberships, each linked to the issuer's own listing.

Place these near the action. A guarantee beside the buy button does more than one buried in the footer.

Fix your forms

Forms are where many visits end. web.dev's payment and address form best practices give these concrete steps.

Ask only for what you need. Long forms put off people on small screens.
Use a visible label for every field. Placeholders vanish once someone types.
Set the right input type, such as email or tel, so phones show the right keyboard.
Add the correct autocomplete values so browsers can fill name and address.
Keep one field for a card number rather than several.
Validate as people type and explain errors in plain words.

Check the mobile experience

Open your site on your own phone, on mobile data, and complete your main action. Time yourself. Note every pinch, zoom and mis-tap.

Make sure buttons are easy to hit with a thumb, the submit button is not pushed off screen, and phone numbers are tappable. Mobile and desktop are scored separately in Core Web Vitals, so test both.

A simple improvement routine

Record your baseline rate for your main page and channel.
Find the biggest drop in your funnel.
Pick one change aimed at that step.
Run it for a few weeks and compare.
Keep it or revert it. Then repeat.

Once visitors turn into enquiries, the next job is closing them. See the one-page growth plan guide for choosing priorities, and the pitching guide for presenting your offer clearly.
