What do Google Tag Assistant "suggestions" mean?
You may get suggestions from Google Tag Assistant. Note that they are only suggestions and in no way will impede the functioning of the dynamic remarketing of your site. You can just ignore them. But if you want to know more, follow this FAQ.
Some suggestions result from certain option settings in your back-office, while others are linked to the basic structure HTML code in Prestashop.
Still let's look at the most frequent suggestions and see how to use them.
"Missing line breaks may cause issues"
"Code should be placed directly above the closing <body> tag"
"Both <script> and <iframe> used"
This is the most mysterious message because it isn't even documented the help forum of Google assistant. At present, it is impossible to avoid.
Once again these suggestions in no way will impede the functionning of the dynamic remarketing of your site. You can just ignore them.
