Downloading .ipa files from other sources, is right or not recommended?

Hi,

I am Ishaq, I have a query and want to ask. I was searching for an educational learning .ipa file on app store but I was not successful to find it on the app store directly. When I search it on google and find it on a website . I click the download button of the required file and it redirects me to the app store where my required file was placed. I am worried to download it. may I need to download it from this link. ( even then it is placed on the apps store but the link was found by a third-party website). or I need to just skip it.

Please, guys, guide me honestly, what should I need to do?

thanks.

Ishaq
