When configured using this method, for offers where the "Thank You" page is hosted on the advertiser's side (offers with auto-login), the pixel will not trigger on the "Thank You" page (but only on the landing page).

Go to your ad account at the link https://ads.google.com
Click "Tools and settings" and select "Conversions" in the "Measurement" section.

Create a new Conversion by clicking the plus icon.

Select the "Website" option.

Next, paste the flow URL or the landing page URL on your hosting (if you downloaded the archive) and click the "Scan" button.

You need to scroll down the page and click the "Set up conversions manually" button.

Next, in the Category drop-down menu, select "Page view".

Next, specify a conversion value if necessary, or select "Don't use a value for this conversion action".

In Count, select "Every".

Next, leave the optimization at the default setting or change it to fit your needs, and click "Done".

Click the "Save and continue" button.

Next, click the "Done" button.

Now go to the created conversion.

And expand the tag setup.

Choose "Set tag manually".

When downloading a landing page to your own hosting, there are 2 tags in the pixel settings: the first one is for all pages, which can be used both on the main landing page index.php or trackers.php — for example, to collect an audience of users who are interested in the product but have not purchased it yet, in order to launch a separate retargeting campaign later and push them to buy. And also on the "Thank You" page invoice2/index.php or trackers_order.php in combination with the second tag to track events.

Therefore, let's note once again: 

• the first tag is placed on index.php or trackers.php to collect data; 
• on invoice2/index.php or trackers_order.php in combination with the second one to track conversions.

the second tag is placed only on the "Thank You" page.

Here you can draw an analogy with Facebook and remember that the first tag resembles the WebView or view event, and the second one is responsible for the Lead event, or in other words, for the conversion.
When using a flow, the ID is taken from the second tag without AW.

And is also pasted into the field with the slash.

This completes the setup.

IMPORTANT: Adding trackers in flows of offers with redirect landing pages (if there are any in the offer) is restricted: if the advertiser supports pixel transmission, the field for entering the pixel will be active. Also, pay attention to the description on the offer card, which may indicate nuances of how pixels work.

A dynamic tracker works in the downloaded landing page. For this, you do not need to insert codes into the landing page. Append ?google_adw_pixel= to the end of the URL (after the domain) or &google_adw_pixel= (after other macros), and after the = sign, insert the tracker ID.
