How do I install a visitor ID tag on WordPress (classic)?

On WordPress (classic), your visitor identification tag goes in: Custom HTML block in page editor or wp_head/wp_footer hooks via functions.php. Note the plan gate: Plugin-enabled plan (Personal, Premium, Business, Commerce) with hosting features activated. The install itself takes minutes; the part that goes wrong on WordPress (classic) is below.

Where the tag goes

  1. Custom HTML block in page editor or wp_head/wp_footer hooks via functions.php.
  2. Plan requirement: Plugin-enabled plan (Personal, Premium, Business, Commerce) with hosting features activated
  3. Paste your vendor’s tag snippet exactly as issued. Do not wrap it in extra script tags or reformat it.
  4. Publish or deploy, then verify (below) before trusting data.

Free and Basic plans filter out <script> tags entirely for security reasons.

How do you verify the tag fires?

Publish site and inspect page source (Ctrl+U) for the script tag in head or body.

Then run through the labeled QA checklist before you rely on the numbers, and set expectations with the match-rate calculator — no vendor identifies every visitor.
