Tips and Tricks 4 – Download Complete History in CSV Format

A collection of useful tidbits to make GTmetrix a little more convenient and/or useful.


Download a CSV file of your complete report history


Just visit the History tab and click on “Download History” on the right hand sidebar.


Depending on your plan, the amount of historical data you can download will vary.

Basic users can download report history up to 3 months from their generation dates.

PRO plan users on any of the Individuals & Professionals plans can download report history up to 6 months while Team & Champion PRO plan users can download report history up to 12 months. Enterprise plan users can download report history up to 24 months.

Note that if you have a large amount of historical reports, your download will take a while to generate.


URL Suffix Method

You can also add /history.csv to the end of any GTmetrix Report URL in a monitored series and directly download the file.

The CSV file will always contain all historical performance data of that URL’s monitoring history (including the latest data).
