What is a Text Overlay?

Text overlays are powerful visual design elements for B2B SaaS landing pages, but poor execution can reduce readability and conversion.

• Contrast & Readability: Text overlays must have sufficient contrast against the background image. Dark text on a light background (or vice versa) is readable. Light text on a light background is not. Poor contrast dramatically reduces readability.
• Accessibility: Users with vision impairments may struggle with text overlays on images. Best practice is to provide the same text content separately (in the HTML), ensuring all users can access the message.
• Mobile Optimization: Text overlays that work on desktop may be unreadable on mobile if the image scales down. Responsive text overlays adjust font size and positioning for different screen sizes.

Example from Flowtrix Projects

For a hero section with light text on a light-colored image, readability was poor and bounce rates were high. We added a dark semi-transparent overlay behind the text, improving contrast significantly. This simple change increased time-on-page by 25% and conversions by 8%.
