Usage 

Automatic placement 

After installing the extension and entering the credentials, the rating is rendered before </body> on every page, centred. Nothing else to do.

Switch it off with autoInsert in the extension configuration if you want to place the snippet yourself.

Content element 

Add the content element ProvenExpert rating where the snippet should appear. The automatic placement then holds back, so there is never more than one review snippet on a page.

Google grants stars only for a snippet that is fully visible, and expects one review snippet per page.

TypoScript 

Add the static template ProvenExpert (server-side) to your root template, then place the rating wherever you need it:

# e.g. below the footer, on every page
page.footerData.950 < lib.provenExpertRating

# optional: override the configured layout
page.footerData.950.style = stars

Fluid 

{namespace pe=Bm1\ProvenExpert\ViewHelpers}

<pe:rating />
<pe:rating style="textInline" />

Caching 

Rating data is cached for an hour by default. If the API is unreachable, the last successful response keeps being served and the API is retried after a minute, so the rating never disappears because of a network hiccup.

Changes made in the ProvenExpert account show up with a delay: this extension caches, and ProvenExpert caches on its own servers as well.

What is sent where 

Only the web server talks to ProvenExpert. The visitor's browser loads nothing from ProvenExpert: no script, no image, no font. No cookies and no sessionStorage entries are created, and no visitor data reaches ProvenExpert.

This covers the display of the rating. Collecting reviews through ProvenExpert is a separate processing activity.
