Placing the size guide link right beside the size selector on Attrangi's mobile product pages raised conversion rate by 7.77% and revenue by 17.80%. ConvertPolo ran this test for Attrangi, and it was published as a VWO case study. It was a single-change A/B test.

## Result

**+7.77% conversion rate**

- Conversion rate: +7.77%. More product page visitors completed a purchase.
- Revenue: +17.80%. Revenue grew more than conversion, which could mean bigger or more orders per buyer, though the source doesn't explain why.

## Control

On the mobile product page, the size guide sat away from the size dropdown. Shoppers had to look for it when choosing a size.

## Variant

The size guide link was moved to sit directly next to the size selector, where shoppers pick their size.

## Why it likely won (our reading)

- Shoppers need sizing help at the moment they pick a size. Putting the guide there removes a search step.
- First-time buyers are often unsure how a brand's sizes run. A guide in plain view gives them the confidence to commit.
- Fewer size doubts can mean fewer shoppers leaving to check elsewhere and never coming back.

## Caveats

Sample size, test length and confidence level were not shared. The result is vendor-published.

## How to run this test

- Hypothesis: If we place the size guide link directly beside the size selector, then more shoppers will buy, because sizing help is there when they make the choice.
- Primary metric: Product page conversion rate
- Guardrail: Revenue per visitor
- Guardrail: Size-related return rate
- Guardrail: Size guide clicks
- Who should test it: Apparel, footwear, rings and any store with sized products, especially with many first-time buyers. It matters less for one-size products or brands whose customers already know their size.
