Creating and adding Google ad tag (pixel)

Go to your ad account by following the link Google Ads - Get More Customers With Easy Online Advertising. Press "Tools and Settings" and select "Conversions" in "Measurements" section
Create a new conversion by clicking on a plus icon
Select "Website"
Next, paste the URL of the flow or the URL of the landing page on the hosting (if you downloaded the landing page archive) and click the "Scan" button
You need to go down the page and click the "Add a conversion action manually" button
In Categories menu, select "Page view"
If needed, set up value or select "Don't use a value"
In Count use "Every"
Next, leave the default or change to suit your needs and click "Done"
Then press "Save and continue"
Next, click on the "Done" button
Now go to the created conversion
And open the tag settings
Select "Install the tag yourself "
When you download a landing page to your hosting, pixel settings have 2 tags: the first one is for all pages, it can be used as index.php on the main page of a landing page, or in trackers.php, for example: to track the users who are interested in the product, but don't buy it so far, so that you can start another retargeting campaign later to put the squeeze on them until they make a purchase. You can also use it on a thank you page invoice2/index.php or trackers_order.php together with the second tag to track events.
So, note again that:

The first tag is used for index.php or trackers.php to collect data;

● for invoice2/index.php or trackers_order.php together with the second one to track conversions.

The second tag can only be used on a thank you page.

Here, we can draw an analogy with FB. Remember that the first tag is about webview (view) event, while the second one is responsible for lead (conversion) event.

If you use a flow, ID is taken from the second tag without AW

and is added to the field with a slash.
Now, setup is finished.
