Affiliate Marketing in Thailand: How to Start and Keep Your Audience's Trust
A practical guide to affiliate marketing in Thailand: choosing a niche, making content that helps people decide, measuring results, transparency and tax basics.
A friend posts a clip reviewing an air fryer with a shopping link and says the commission has become extra income. You try it too, pasting links to a dozen best-selling products. A month later almost nobody has clicked. This happens a lot, because affiliate marketing that works does not start with links. It starts with an audience that trusts your recommendations.
What is affiliate marketing?
Affiliate marketing means recommending another brand's product or service through your own link or code. When someone buys through it, you earn a share under the programme's terms. In Thailand there are programmes run by marketplaces, by video platforms with built-in shops, and by brands running their own reseller schemes. Commission rates and rules change often, so read each programme's current terms before you start.
Choose the right product niche before making content
Start with what you actually use or understand
If you are an office worker who cooks every day, small kitchen tools or food storage boxes will come across far more naturally than cosmetics you have never used. Audiences quickly tell who reviews from experience and who is reading specs from the product page.
Pick categories where people think before buying
Products people compare before deciding, such as headphones, office chairs or online courses, give your content a real chance to help. Cheap impulse buys compete on price and speed rather than knowledge.
Go narrow first, then expand
“Home office gear for condo dwellers” is far clearer than “general products”. A narrow focus helps people remember what you are good at and come back when they need to buy in that category.
Content that helps people decide
- Reviews after real use covering both strengths and limits, such as “great sound, but my ears hurt after two hours”.
- Comparisons of two or three options in the same budget, saying who each suits.
- How-tos where the product is part of the solution, such as setting up a desk in a small room, then recommending what you used.
- Answers to questions people search for, such as “how to choose an office chair under 3,000 baht”, which suits articles or long videos that keep being found.
An example closing line that does not oversell: “If you sit at a desk for hours like I do, this one is better value. If you only use it some days, the first one is enough. The link is in the comments.”
Transparency is long-term capital
Tell your audience plainly that the link is an affiliate link and you earn a commission if they buy. A short line like “This is an affiliate link; the price is the same for you” protects trust, and many platforms already require disclosure in their rules. Never praise products you have not used, and never make health claims without evidence, because you lose credibility and may break the law.
Measure properly, not just views
Numbers worth tracking
- Link clicks per piece of content
- Purchase rate from clicks (conversion)
- Revenue per piece of content, to see which format is worth your time
Keep a simple weekly sheet
Record the content title, format, product, clicks and sales. Within a few weeks you will see whether your comparisons or how-tos perform better, and you can make more of what works.
Do not overlook tax
Affiliate income counts as income for personal income tax. Keep records of income and expenses from day one. How to file and what you can deduct depends on the income type and your situation, so check with the Revenue Department or a tax professional before you file.
People do not click because you posted a link. They click because they believe you help them choose.
Where to start
- Choose one narrow product category you actually use.
- Join an affiliate programme that sells that category and read its disclosure rules.
- Create your first three review or comparison pieces, including each product's limits.
- Log results weekly and repeat the format that gets the most clicks and purchases.
- Separate your income records from the start so tax is easier to handle.
