[Resolved] WCML Google Crawler

For reference WCML said it may be possible these filters, is that the case and what could be used?

Hello,

We are due to test the following filters to see if we can use that resolves the issue.

add_filter( 'wcml_geolocation_get_user_country', function( $userCountry ) {
if ( isset( $_SERVER['HTTP_USER_AGENT'] ) && strpos( $_SERVER['HTTP_USER_AGENT'], 'Googlebot' ) !== false ) {
return 'GB'; // GB country code or another country code that allows GBP currency.
}

return $userCountry;
} );

add_filter( 'wcml_client_currency', function( $currency ) {
if ( isset( $_SERVER['HTTP_USER_AGENT'] ) && strpos( $_SERVER['HTTP_USER_AGENT'], 'Googlebot' ) !== false ) {
return 'GBP';
}

return $currency;
} );

I have however found another workaround similar to the above, using Cloudflares transformation rules. In summary, the HTTP Response header rule follows these steps (Similar to the above filters)

Firstly, the following filter needs to be applied for WCML to use cookies:

add_filter ('wcml_user_store_strategy', function($strategy, $key) {
return'cookie';
}, 10, 2);

Then create the following Cloudflare Transformation Rule (HTTP Response Header Modification Rule).

If incoming requests match
1. Country = United States
AND
2. User Agent 'Contains' Googlebot
AND
3. Cookie 'Does not Contain' wcml_client_currency

Then

Add 'Set-Cookie' = wcml_client_currency=GBP

Step 3 stops every single request adding a wcml_client_currency cookie, therefore adding it only once and not repeatedly.

Hello,

We've noticed inconsistencies with the cloudflare workaround, have tried your code but doesn't seem to make any difference when using googles link inspection. prices are still showing in USD.

Hello,

I adapted the code to the following, so any google bot should exclude it.

add_filter( 'wcml_client_currency', function( $currency ) {
if ( isset( $_SERVER['HTTP_USER_AGENT'] ) && strpos( $_SERVER['HTTP_USER_AGENT'], 'Google' ) !== false ) {
return 'GBP';
}

return $currency;
} );

Even using this and with a cookie being manually set via Cloudflare to GBP by default, cached pages are showing as USD or even EUR on first load despite being in the UK.

So this issue seems to be litespeed cache related, as it's caching non-default currencies and serving them. Geolocate after load is then changing back to the default currency.
