# Verify Size of Linked Files

Link Analyzer

## What is this warning?

Our tool was unable to determine the size of a file you are linking to. This can happen if the server hosting the file doesn't provide size information correctly. It's a good idea to manually check the file to ensure you aren't unknowingly linking to an excessively large file that could cause a poor user experience.

## How to Fix This Issue

### How to Fix It

#### The Problem

Our analyzer could not retrieve the `Content-Length` header for a linked file.

#### The Solution

Download the file yourself to check its size. If it's large, consider adding the file type and size to the link text as a courtesy to your users (e.g., 'Download Report (PDF, 10 MB)').

#### Why This Works

Manually verifying uncertain links helps you prevent a negative user experience where a user might accidentally start a very large download without warning.

### SEO Impact

This issue can affect your site's search engine rankings and user experience. Addressing it promptly helps ensure optimal performance and visibility in search results.

### Automatic Detection
