Getting discrepancy in result of CLI and https://pub-ads-audits.appspot.com/

[ankitjain082]

I am using CLI command for run the ads-lighthouse-plugin which is "node index.js --output=json --output-path="results" --output=html --max-wait-for-load 60000 --quiet --chrome-flags="--headless" --full --emulated-form-factor desktop " and get result.

From last week I am getting value of Perf score is very low so I verified my website on https://developers.google.com/publisher-ads-audits and found huge difference for perf score.

I am getting Perf score through CLI is 14 and through web is 60.
Can anyone help me to solve this issue or let me know if i am doing anything wrong.

I am sharing snap shot for the same.

Thanks,

Hi Ankit, sorry for the late reply. I expect the difference is related to simulated throttling (more information about throttling can be found at https://ads-developers.googleblog.com/2020/04/improving-accuracy-of-publisher-ads.html)

You can see device information at the bottom of the report:

By default the CLI simulates a slow device on a 3g connection for desktop but the web service does not. You should be able to reduce the discrepancy on the CLI by passing in --throttling-method=provided, but there may still be some discrepancies based on the environment of the CLI vs the web service.

Hopefully this resolves your issue but let me know if you have any additional questions.
