# Testing a Customer Logo Bar for Trust on a Homepage

## Hypothesis

When visitors see logos of organizations they recognize and that resemble their own, they may more readily believe that businesses of their size use the product. That reassurance may lift the primary action completion rate, while logos that do not match the visitor's scale may weaken the effect or reverse it.

## When to run this test

This test makes sense when not knowing who uses the product seems to hold visitors back, such as prospects asking sales for examples of similar customers, survey answers that mention a lack of trust, or sessions that reach the offer section and leave without acting. If the logos work, visitors who see the strip keep browsing and completed actions rise with no drop in leads that fit the target profile. If the hesitation is about price or the offer itself, a logo strip will not fix it, so work on that first; before building the strip, confirm you have permission to use each logo rather than assuming it.

## Primary metric

**Primary action completion rate**: Compare completion of the target action to see whether a customer-logo strip changes behavior.

## Other metrics

- **Scroll depth**: Make sure the logo strip does not interrupt browsing.
- **Bounce rate**: Track exits that may follow a mismatch in perceived scale.
- **Qualified lead rate**: Make sure the share of leads that fit the target profile does not fall.
- **Page load time**: Ensure logo images do not slow the page.

## What to check before and during the test

- **Logo strip**: Add a predefined set of genuine customer logos in one specified location.
- **Keep constant**: Keep page copy, CTA, testimonials and other sections unchanged.
- **Audience**: Review existing audience segments rather than changing the logo set in this test.
- **Visibility**: Keep logos recognizable on mobile.
- **Separate tests**: Compare logo set, placement or industry-specific selection separately.

## What to watch when reading the result

- A rising primary action completion rate paired with a falling qualified lead rate may mean the logos draw visitors outside the target profile, so do not count that lift as a gain on its own. Any worsening in bounce rate, scroll depth or page load time is also a cost of the strip.
- This logo set, this placement and the page where the test ran limit what the result tells you; run it again on pages for other industries before carrying it there. Check that the logos stay recognizable on mobile, because a result from logos too small to read does not measure the strip at all.
- If the result is borderline, do not decide on a single estimate; a small gap could hide a real gain or a small loss. Enter each arm's completions and visitors in the [A/B test significance calculator](https://alidemirbas.com.tr/en/calculators/ab-test); if it does not mark the gap as significant, this test has not settled the effect of the logos. Review existing audience segments separately as well.

## Frequently Asked Questions

### Which logos can appear in the customer-logo strip?

Use genuine customer logos with verified usage permission. Fix the set and location beforehand. Sector-specific selections or different logo sets require separate comparisons.

### Why might customer logos put visitors off?

Unfamiliar or differently sized organizations can suggest the product is unsuitable. Use completed main actions as the primary outcome and inspect qualified leads, exits and displaced page content.

### Can results be extended to other industry pages?

Validate other contexts before generalizing. Examine predefined audience segments and confirm mobile recognition and acceptable image-loading performance.
