- No credit card required. We recommend starting small first
"A/B testing requires an expensive tool" or "you can't do it without an engineer" โ you may have that impression. But today, you can get started for free, with no code, using just one tag. This article shows you how to start today, even without specialized knowledge.
Why is A/B testing thought to be expensive in the first place?
Traditional A/B testing tools were often built for large enterprises, with annual costs ranging from hundreds of thousands to tens of millions of yen. Many required engineering work to implement, which spread the impression that A/B testing is "specialized and expensive."
However, there are now more lightweight tools that let small sites and individuals get started for free.
3 steps to get started for free, no code required
- Paste one measurement tag: Just add a single tag to a shared part of your site, such as the header. On WordPress, you can paste it right from your theme settings.
- Create a variant through a visual interface: Choose and specify changes to headline or button copy, colors, and more while looking at the actual page. No coding required.
- Launch it and check the results: Serve visitors either A (the original) or B (the variant), and see which one performs better.
How much can you do without code?
Without writing any code, you can try changes like these.
| What you can do | Example |
|---|---|
| Change the copy | Swap out headline or button text |
| Change the appearance | Adjust styles such as color and size |
| Hide an element | Hide an unnecessary element for comparison |
Tips for making the most of "free"
- Start with just one spot: Don't try to do too much at once โ start with a single element that seems likely to have an impact. This makes it easier to see what actually worked.
- Use a heatmap to aim your test: Rather than testing at random, it's more efficient to use a heatmap to find "problem areas" first, then run your test there.
- Keep going in small steps: Even if one test doesn't produce a dramatic change, stacking up small improvements is what drives real results.
