Offers and seasonal messages on your homepage

Key takeaways

A promotional banner on a homepage works when it is one offer, clearly dated, relevant to most visitors and placed so it supports the main message rather than replacing it. Seasonal homepage updates, such as winter boiler checks or a Christmas menu, should change the proof and wording around the main action, not stack banners on top of it.

• One offer at a time, with a real end date.
• Support the main message; never replace the headline.
• Remove it the day it ends.
• Genuine reference prices only; the CMA can fine misleading ones.

When does an offer banner help a homepage?

An offer banner helps when the offer is relevant to most homepage visitors, time-limited for a genuine reason and simple enough to understand in one line, such as 'Book a boiler service before 31 October and get a free carbon monoxide alarm'. It hurts when it is stale, irrelevant or one of several.

• Why your homepage is not converting visitors into customers
• Seasonal offers in the menu: promote without clutter

Where should an offer appear?

Put a short offer line in the hero's subheadline or as a slim bar above it, linking to a page with the details. Do not replace the headline with the offer, because visitors still need to know what you do. Big rotating promo sliders are the least effective option.

• Announcement bars: useful notice or navigation clutter?
• Carousels on mobile websites: keep, fix or remove?

How do you update a homepage for the season?

Change the context, not the structure. A heating engineer might lead with servicing in autumn and repairs in winter; a restaurant swaps the hero image for the seasonal menu. Keep the main action the same and put dates in your calendar to change the content back.

• How often should you update your homepage?
• Choose a homepage hero image that sells

What rules apply to offers?

Offers must not mislead. 'Was' prices must be genuine, deadlines must be real and conditions must be clear. The CMA can now fine businesses directly under the Digital Markets, Competition and Consumers Act 2024, and promotions must also follow the CAP Code's rules on sales promotions.

When should you skip offers on the homepage?

Skip them if discounts would undermine a premium position, if offers only apply to a small group of visitors or if nobody will remember to remove them. An out-of-date offer says the business is not paying attention.

• Raising prices? Your website has to justify them

What does this look like in practice?

A pattern we see: three overlapping banners for offers that ended months ago, pushing the headline below the fold on phones. Removing them and adding one dated offer line under the subheadline, with a calendar reminder to take it down, restores the first screen.
