Render gap
In short
The content difference between a page's raw HTML and how it looks in the browser after JavaScript runs.
Example
A product description loaded only by JavaScript, so the page the bot sees has no product information.
Where you'll see it in AILens
The raw HTML versus render control (TEC-004) and the render gap section of the PDF report.
Many AI bots do not run JavaScript. If key information only appears after rendering, the page can look empty to them.
