<h4>Why this plugin exists</h4>
<p>Original Plugin (discontinued): https://de.wordpress.org/plugins/json-ld-for-article/</p>
<p>Sadly, the original plugin is not being developed anymore. So I decided to fix some bugs like invalid markup,<br />
    missing tags, putting objects into fields instead of just URLs for images, and implementing for more than just<br />
    articles.</p>
<p>Also, this plugin plays nicely with <a href="https://de.wordpress.org/plugins/yet-another-stars-rating/" rel="nofollow ugc">YASR – yet another star rating</a>. It will<br />
remove yasr’s invalid jsonld-syntax and instead use YASRs rating.</p>
<p>All requests are being cached and purged on page update/edit etc.</p>

<h4>Original description</h4>
<p>Search engines such as Google are using structured data markup in many ways—for example, to create rich snippets in search results. Search results with rich snippets will improve your click through rates and increase the number of visitors on your website.</p>
<p>It has been a tedious task to add the complicated Schema.org markup to your website – sometimes it wasn’t even possible due to technical constraints. Now, thanks to <strong>JSON-LD</strong>, almost any website can enjoy the benefits of structured data. For WordPress users it’s even easier thanks to this plugin.</p>
<p>JSON-LD for Article is simply the easiest solution to create valid schema.org microdata markup on your WordPress site automatically from your web content and its metadata. All you need to do is install and activate the plugin, and it will generate JSON-LD markup of your posts that Google and other search engines can use for rich snippets using the schema.org for articles.</p>
<p>Some WP themes include traditional schema.org markup embedded in the html code the theme produces. If you are using one of these themes, this plugin is probably not necessary. If the markup produced by the theme contradicts the data specified in the JSON-LD, the added information might be not be helpful at all. Thus you should check the markup provided by the theme before adding possibly unnecessary JSON-LD to your site.</p>
<p>On the other hand, if you use a custom theme, it is easier to use the functionality provided by the plugin than to invent the wheel again and add the markup in html. Very often, this leads to html code that is difficult to read and is not valid structural markup according to Google’s validator.</p>
<p>Our plugin:</p>
<ul>
<li>Helps your site to earn rich snippets in Google’s SERP.</li>
<li>Does not depend on other plugins or external code.</li>
<li>Is simple to install: plug-and-play, no need to configure anything.</li>
</ul>

wp-jsonld is the continuation of the simplest solution to add valid schema.org microdata as JSON-LD-script to your blog posts and articles.

<h4>Varying Prices on Product Variations is Tedious and Error-Prone</h4>
<p>Want to add $5 to every blue product you sell? Maybe you sell jewelry with birthstones, and some stones cost more than others. If all “X-Large” products cost 7.5% more, you’d have to manually calculate and change every “X-Large” variation of every product.</p>
<h4>Markup by Attribute Adds ‘Markup’ to Attribute Terms</h4>
<p>Markup by Attribute solves this by letting you add a markup (or markdown) to global attribute terms. If the attribute is ‘Color,’ you can add “+5” to Blue while leaving Green and Yellow alone. When you set regular and sale prices, every blue product will automatically be $5.00 more.</p>
<p>This plugin does one thing – it adds pricing control to WooCommerce’s global product attributes. If your products vary in price based on options like size, color, or material, Markup by Attribute lets you set those price differences once at the attribute level rather than manually adjusting each product variation.</p>
<h4>Key Features</h4>
<ul>
<li>Fixed value markups (like $5) or percentage markups (like 5%)</li>
<li>Positive markups for price increases, negative for decreases</li>
<li>Integrates with WooCommerce’s existing ‘Set regular price’ and ‘Set sale price’ bulk actions</li>
<li>Shows price differences in the dropdown options to help customers make informed decisions</li>
<li>Provides itemized price breakdowns in variation descriptions</li>
<li>Quick bulk update tools to reapply markups when values change</li>
<li>Support for both regular and sale prices</li>
<li>Option to show or hide markup details in various places</li>
</ul>
<h4>Use Cases</h4>
<ul>
<li>Size-based pricing: Charge more for larger sizes, less for smaller sizes</li>
<li>Material upgrades: Add costs for premium materials</li>
<li>Add-on services: Pricing for monogramming, gift wrapping, etc.</li>
<li>Attribute-driven costs: Any situation where product options consistently affect pricing</li>
</ul>
<h4>New in Version 4.3</h4>
<ul>
<li>New Base Price column for easier price management</li>
<li>Improved markup visualization in the product editor</li>
<li>Enhanced bulk update tools</li>
<li>Better multilingual support with new translations</li>
</ul>
