How do I put Code from Google Remarketing on every page of site?

I have been asked by the company that does my adwords management to put a code from google remarketing on every page of my site.

How do I go about doing this? With google analytics it was just a plugin that made it easy and fast. By every page, do they mean every individual product page as well? I have over 3,000 products in my store.

Just add the code to a copy for your template of tpl_main_page.php

Will that put it on every page of the site or just the homepage?

Every page

I'm so sorry but I searched developers tool kit for tpl_main_page.php and there are heaps of them. I don't know which one to put it on.

Most say public_html/includes/templates/template_default/ not my actual template name.

Only one has my current template name instead of template_default but that has popup image in there too in public_html/includes/templates/my actual template/popup_image_additional/tpl_main_page.php

/includes/templates/YOUR_CUSTOM-TEMPLATE/common/tpl_main_page.php

If there is no tpl_main_page.php in that folder, COPY one from:

/includes/templates/template_default/common/

Then open that copy for editing using a plain text editor.

Insert your code just above the </body> tag.
