RatingStar is the review tool for businesses: collect customer reviews, bundle reviews from Google and other platforms, and show them all on your own website. RatingStar.de Seal brings them into WordPress:

A seal widget in nine variants — the static round seal and banner seal, plus the live widgets: profile card, trust bar, hero snippet, featured quote, carousel, wall of love and footer bar.
A site-wide seal: show the floating profile card or the footer bar on every page — no theme edit, no per-page block.
Google review stars — server-side JSON-LD (LocalBusiness with AggregateRating) so search engines can show star ratings for your site.
A static image mode: the round seal, banner seal and profile card as a plain SVG image, linked to your profile — for contexts without JavaScript.

Enter your RatingStar profile slug once under Settings RatingStar, then place the seal anywhere with the [ratingstar] shortcode or the RatingStar Seal block — or switch on the site-wide seal.

Customising the look: every embed accepts the appearance attributes produced by the embed generator in your RatingStar portal (for example pc-color, car-count, footer-bar-bg). Use them as shortcode attributes ([ratingstar variant="carousel" car-count="4"]), paste them into the block’s “Embed attributes” field, or into the site-wide settings — seal.js validates the values.

Why it stays fast and clean:

The seal script (seal.js) is loaded asynchronously and only on pages that actually contain a seal.
The JSON-LD rating is fetched server-side — key-based when an API key is set, so it survives a profile rename — and cached for 6 hours; it is printed only on your front page.
When the JSON-LD output is enabled, the seal’s own snippet is suppressed so the AggregateRating is never duplicated.
The static image is rendered and cached by ratingstar.de, with long-lived CDN and browser caching.

External services

This plugin connects to the RatingStar platform (https://ratingstar.de), a review collection and rating seal service operated by Baumgärtner Marketing GmbH. The connection is what the plugin is for: it displays your RatingStar seal with live rating data and outputs your rating as Google review stars. Without a RatingStar profile the plugin does nothing.

What is sent, and when:

Seal widget: When a page containing a seal is shown, the visitor’s browser loads seal.js, the seal styles and the rating data for the configured profile from ratingstar.de, and requests a tracking pixel that counts the seal impression (and, on click, the click). As with any web request, the visitor’s IP address and user agent technically reach the server; the plugin itself transmits no names, e-mail addresses or other personal fields.
Static image mode: The visitor’s browser loads a single SVG image from ratingstar.de.
Google review stars (JSON-LD): Your web server — not the visitor — fetches the rating summary from ratingstar.de (identified by your site URL in the user agent) and caches it for 6 hours. No visitor data is involved.
Settings: When you save a changed profile slug, your web server verifies it against ratingstar.de once.
