Compliance may not be the most exciting part of building an online business, but it deserves attention before you publish a promotion or launch an advert. The wording in your ad, the claims on your page, the way you disclose an affiliate link and the emails you send all affect the experience you create for your audience.
You do not need to memorise every rule before you begin. You do need to know where to check the current requirements, make honest claims and review the full journey from the first post or advert to the page and any follow-up.
This guide focuses on practical points for beginners in the UK. It is general information, not legal advice. Rules can differ by location, platform and type of promotion, so check the latest official guidance for your situation.
What does online marketing compliance cover?
Online marketing compliance is not just about the advert itself. A useful starting point is to review each part of the journey:
- The content: Is it clear when you are promoting something commercially?
- The claims: Can you support statements about results, features, savings or performance?
- The destination: Does the page match what the ad or post led people to expect?
- The sign-up: Is it clear what someone is requesting and whether they are also agreeing to marketing emails?
- The follow-up: Can people identify who is contacting them and unsubscribe easily?
Looking at the whole route can help you spot unclear wording or a broken step before you send more people through it.
Make advertising and affiliate promotions clear
If you promote a product through an affiliate link, you may earn a commission when someone buys. Make that commercial connection clear where people see the recommendation.
The UK Advertising Standards Authority (ASA) says affiliate marketing should be obviously identifiable as advertising. On social media, affiliate promotions should be identifiable upfront. On a blog, if only some recommendations use affiliate links, make the relevant content and links clear where they appear. A general disclosure hidden at the bottom may not be enough for readers to recognise a specific promotion.
Use plain wording people understand, such as “Ad” or “Affiliate link — I may earn a commission if you buy through this link.” The exact wording and placement should suit the content and the platform. Read the ASA’s affiliate marketing guidance before publishing a promotion.
Use claims you can support
Marketing copy can be persuasive without promising a result you cannot prove. Be especially careful with claims about earnings, guaranteed outcomes, how quickly something works, “number one” rankings, discounts and product performance.
Before making an objective claim, ask:
- What exactly will a reader understand this statement to mean?
- Do I have reliable evidence to support it?
- Have I explained important conditions or limitations clearly?
- Does the overall impression remain accurate, including the headline and image?
The ASA’s guidance on misleading advertising explains that advertisers should hold evidence for objective claims and should not omit significant qualifications. If you cannot support a claim, remove it or rewrite it as a clearly framed opinion.
Check that the landing page matches the advert
Someone who clicks an ad or post should arrive at a page that follows naturally from what they were promised. If the ad offers a beginner’s guide, the page should explain that guide clearly. If the ad promotes a product, the destination should not hide important information that would help a person decide.
Before sending traffic, check the page on a phone. Make sure the main message is easy to understand, the links work, the price and key conditions are clear where relevant, and the next action is obvious. Also check the current advertising rules for the platform you are using. Meta’s Advertising Standards apply to ads across its technologies, and Meta explains that policy breaches can lead to advertising restrictions.
Be clear about email sign-ups and follow-up
An email address collected to deliver a requested resource is personal information. Explain what the person is signing up for and what messages they can expect. Do not assume that asking for a download automatically gives permission for every kind of future promotion.
In the UK, PECR rules generally require consent before sending unsolicited marketing emails to individual subscribers, unless a specific exception such as the customer “soft opt-in” applies. The rules differ for corporate subscribers, and data protection requirements may still apply. Make sure your form and follow-up fit your circumstances rather than relying on a generic template.
Marketing emails should identify who is sending them and provide a valid contact address. Give recipients a simple way to opt out in each marketing message, and act on unsubscribe requests. The ICO’s current PECR email marketing guidance explains consent, opt-outs and the different subscriber rules.
A simple compliance check before you publish
- Identify the promotion. Mark affiliate or paid content clearly and in the right place.
- Review every claim. Remove unsupported promises, earnings statements or performance claims.
- Follow the click. Check that the landing page delivers what the content promised.
- Test the process. Open the page on mobile, submit a test form and check the confirmation and delivery emails.
- Check your email permissions. Make the sign-up expectations clear and include a working unsubscribe route in marketing emails.
- Read current platform rules. Policies change, so check the official requirements before each campaign.
This checklist will not cover every legal or platform requirement. It gives you a practical routine for catching common problems and knowing when to consult the official guidance.
Compliance is part of a trustworthy customer journey
It is tempting to treat compliance as paperwork to deal with after the marketing is finished. In practice, it is part of how you communicate with people: explain the offer honestly, make commercial relationships visible, respect email choices and ensure each step matches the last.
Before your next campaign, take a few minutes to review the whole journey: the post or advert, the page people reach, the sign-up and any follow-up email. If a claim or requirement is unclear, pause and check the current guidance from the relevant authority or platform before publishing.
