A cache is a temporary storage in your internet browser that saves parts of websites you visit, such as images, scripts, or previously entered data. This helps pages load faster when you return to them.
Cache data can sometimes also include information from forms or login sessions. Over time, this stored data can become outdated or too large, which may cause certain websites or tools, including parts of Google Ads, to load incorrectly.
If you experience loading issues or errors, clearing your browser cache is often a simple way to fix the problem and allow the browser to store fresh data again.
