1. Google (GSC + GA4)

One sign-in enables search queries & pages from Search Console and site traffic from GA4. Enable APIs in Google Cloud (see setup doc).

On your website first: Take your Google tag (gtag.js) from Google Analytics → AdminData streams → your site → View tag instructionsInstall manually. Paste that snippet in the <head> of every page (or your theme / layout). Without it, GA4 traffic tables stay empty — GSC data still works once the property is verified.

If Google shows redirect_uri_mismatch, open this page and paste the URL into Google Cloud → Credentials → Authorized redirect URIs.

If you see “Google hasn’t verified this app” here but not on GBP: Search Console + GA4 use different (sensitive) scopes than Business Profile. Your app must pass Google’s verification for those scopes separately — or use Test users / Advanced until then.

2. Bing Webmaster

Submit URLs to Bing after you add your site in Bing Webmaster Tools. Register an OAuth app under Settings → API Access.

Why Bing: Bing indexing feeds Microsoft Copilot and related discovery. There is no public “submit to ChatGPT” API — strong Bing + on-page content supports AI visibility.
