Before deploying, maybe You needs :
Google CSE Id
How to create Programmable Search Engine ID here (opens in a new tab),
and get your search engine id.
Copy Id to env.local file as GOOGLE_CSE.
Google adsense code (Pub id & Unit Id)
Ad-unit-code Example
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-1234567890"
data-ad-slot="unit-12345678990"
data-ad-format="auto"
data-full-width-responsive="true"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
As the ad code sample above, so your PUBLIC_GOOGLE_ADS_CLIENT_ID is ca-pub-1234567890, and your ADS_SLOT_1...5 is unit-12345678990 for env.local file.
